ANALYSIS OF MECHANICAL VERSUS HAND HARVESTING OF SUGARCANE


Francisco Rohrmann and Jose Alvarez


(C) IFAS, University of Florida, 1986


INTRODUCTION

Comparing the economics of mechanical and hand harvesting

methods of sugarcane is not an easy task. Sugarcane producers have

difficulty determining which method would result in higher net

returns. Furthermore, the decision has strategic implications

which affect the performance of the sugar industry.

While one method is more labor intensive, the other is more

capital intensive. The mechanical method involves a large capital

investment and results in higher fixed costs. It has lower labor

costs, however, it has higher field losses and higher trash

content.

The comparison process is aggravated by the fact that some

differences between the two technologies are measurable, while

others have more qualitative characteristics that are difficult

to measure at the present time. Although the mechanical

harvesting method may result in a lower cost per gross ton, this

method offers less control over the quality of the cane

delivered to the mill. This could result in lower net returns

than the hand cut method. Other measurable quality

characteristics include the percent trash contained in the

harvested cane, which in turn affects the percent sucrose and

commercial recoverable sugar at the mill. The mechanical

harvesting method has less topping efficiency, thus a higher
5












percent trash. In addition, it presents problems with root

damage to subsequent stubble crops which affect long-term

profits.

The strategic considerations for the alternative harvesting

methods include dependability of labor force, versatility and

mobility, logistical problems with the overall harvesting

schedule, tax advantages, capital investments, and opportunity

cost of capital.

Microcomputer programs to address this important issue are

lacking. The one appearing in Alvarez et al. (1985) is mainly

concerned with field operations. The software explained in this

manual presents a framework for estimating costs and returns for

the two harvesting methods and follows the methodology outlined

in Zepp and Clayton (1975). The computer program can be used to

determine the potential effect of changing input and output

prices, intensity of input use, capital costs, machinery

investment, and other factors that influence costs and returns.

The computer program increases accuracy and saves time. In

addition, it provides consistent and uniform information required

for sound managerial decision making.

The example computer runs in this manual pertain to a

2500-acre sugarcane operation in south Florida. The program,

however, can be used for larger or smaller operations and in

other areas.

The user of this program should be aware of its limitations.

The major limitation is that it provides information that must be

analyzed, as opposed to a decision-aid that helps determining
6












which fields should be harvested and by what means. The costs and

returns results can be used as a tool to complement other

analyses. For example, the program does not incorporate strategic

implications of employing either harvesting method.

Considerations such as added risk with mechanical harvesting due

to large freeze losses or wind damage, and future yield declines

due to stubble damage, although important for estimating

long-term profits, are not included in the program. Since

determining the differences in costs and returns between the two

harvesting methods is the major objective of this program, only

the production, harvesting, hauling and milling costs (and

associated returns) are considered in detail. After reading this

manual, the user will be able to determine the program's

limitations and gather the necessary information to complement

this analysis.



HARDWARE AND SOFTWARE REQUIREMENTS

The computerized "Analysis of Mechanical Versus Hand

Harvesting of Sugarcane" program consists of this user's manual

and a distribution disk. The distribution disk is to be used in

conjunction with Lotus 1-2-3. To use this program, an IBM

Personal Computer, or compatible, with a minimum of 192 Kilobytes

of RAM is required. Version 1, 1A or 2 of Lotus 1-2-3 is also

necessary. All versions require at least two disk drives and

versions 1A and `2 support a hard disk. If printed reports are

desired, a printer is also needed.

The user should become familiar with Lotus 1-2-3 before using
7












this program by working at least the first four lessons of the

1-2-3 Tutorial Disk. Once one has learned how to move the cell

pointer and enter words and numbers into the spreadsheet, this

program should be relatively easy.



GETTING STARTED

Before running the program for the first time, the user

should make a back-up copy of the distribution disk and store it

in a safe location. The instructions for duplicating diskettes

can be found in the IBM user's manual.

If you are using a dual floppy disk drive computer, begin by

placing the Lotus 1-2-3 disk in drive A and the distribution

disk in drive B. If you are using a hard disk system consult your

MS-DOS manual and Lotus 1-2-3 manual for accessing

subdirectories. Turn the computer on and answer the date- and

time prompts. Then press : for the 1-2-3 Lotus Access

System and, finally, when* requested, press any key to continue.

The first screen displays the title and version of the

program. It also gives the user two options. The first one shows

the credit and disclaimer screens. Users are encouraged to select

this option when running the program for the first time. To read

this information, look at the number shown in the cell pointer. If

it is the number you wish, just press . If another number

appears in the cell pointer, type the number you wish (numeric

entries do not require special characters) and press

twice. If number 1 is selected, the credit screen is then

displayed. To read the information contained in the disclaimer
8












screen, press when the cell pointer is in cell E121. To

run the program, press in the E144 cell at the bottom of

the screen to access the main menu.

The second option allows the user to skip the steps described

above when number 2 is selected from the title screen. This will

display the screen access menu to start running the program. If

the number in the cell pointer corresponds to the desired

section, press . If not, type the number you wish and

press twice. The Z command will allow you to go back

to the Screen Access Menu to select another section, and the

A command will return the program to the title screen. These

two macros are mostly used after an input section has been

completed and the program is in READY mode. If a mistake is made

while trying to execute a macro, some letters and numbers may

appear inside the cell pointer. When this happens, enter the

desired number, press twice, then press the macro, and

press again.



BUDGET DESCRIPTION

The costs and returns program presented in this manual has

over 160 lines of information, some of which are provided by the

user and some of which are calculated by the program. Obviously,

it is too long to be displayed at one time on a typical 24-line

microcomputer screen. The program was designed to be displayed in

short, logical sections.

If Version 1A or 2 of Lotus 1-2-3 is used, the numbers to be

entered by the user are highlighted and the rest are calculated
9












by the computer. Neither is highlighted in Version 1. The

numbers within boxes in the Tables presented at the end of this

manual are input figures provided by the user (unprotected cells)

while the rest are calculated by the program (protected cells).

However, almost all the cells that are filled with formulas are

protected in all' versions, meaning that, if a number is typed by

accident into a cell containing a formula, a beep will alert you

of the fact that you are trying to replace a protected formula.

The figures in the example run are for demonstration

purposes only. Most of them, along with some formulas, were taken

from Zepp and Clayton (1975). If the user has better estimates

than those calculated by the program, the corresponding changes

should be made. First, move the cell pointer to the cell you want

to change; then unprotect the cell (/Range Unprotect ),

then type the new estimate. Be sure to have a back-up copy of this

program because the formula will be erased after the new estimate

has been entered. An alternative way to change a figure

calculated by the program is to modify the existing formula or

enter a new one. In that case, press the CF2} Edit key and make

the needed adjustments.

The program provides a Table of Contents called the Screen

Access Menu, which lists the major sections of the program (Table

1). The Screen Access Menu, as explained above, is displayed

whenever the Z keys are pressed once the data disk has been

booted by the system. At the bottom of the menu the user is

asked to enter the number of the section desired. The procedure is

explained twice in the "Getting Started" section of this manual.
10












It is highly recommended to go back to the Screen Access

Menu after one section of the program is completed before moving

to another section. Each section occupies only one screen.



General Information Section

By selecting number 1 from the Screen Access Menu, the

program goes to the General Information Section (Table 2). When

the program reaches this section, the cell pointer will be

located in the "Cane Price" row. The user must enter the expected

average price per standard ton of sugarcane delivered to the

mill. The molasses payment must be specified in terms of cents

per gallon. The price of raw sugar, in cents per pound, is also

requested. The proportional share of the molasses revenue paid to

the grower also should be entered.

On the right hand side of the screen, the user should see the

"Interest Rate" column and enter the corresponding figure for

machinery loans. This figure must be entered as a decimal and the

program will make the conversion to an integer figure. In the

example run, 0.12 was entered and the program translated it to

12% on the screen although the 0.12 is used for calculation

purposes.

The last six figures to be entered in this section are

related to growing, harvesting, hauling, and processing.

Production costs should represent the pre-harvest fixed and

variable costs (harvesting costs are entered in another section

of the program) expressed in terms of dollars per harvested

acre. The user should enter the information for both hand and

11












mechanically cut cane. The cost of hauling the cane to the mill

must be expressed in terms of dollars per gross ton. Milling

cost must be entered in dollars per net ton for the hand

harvesting method. No figure is needed for the mechanical method

because the fiber content represents the proportion of fiber per

net ton of cane when it is received at the mill. The

mechanically-cut cane usually contains a higher fiber content

than the hand cut cane. The program accounts for this by

proportionally reducing the grinding capacity and proportionally

increasing the milling costs.

The average molasses yield must be expressed in gallons per

net ton. Usually, mechanically cut cane has a higher yield of
I -
molasses than hand cut cane. This is due to a higher proportion

of trash, which includes immature stalks. The last figure of

this section is related to the amount of "commercial recoverable

sugar". This figure should express the number of pounds of sugar

that are obtained from one net ton of sugarcane delivered to the

mill.

These entries must be estimated carefully since they are

used to determine the efficiency of both harvesting methods. The

figures provide the necessary information for calculating

revenues, costs and returns on a total, per acre and per net ton

basis, and thus determining the relative profitability of both

operations.



Land Use and Yields

Selecting number 2 from the Screen Access Menu takes the
12












user to the Land Use and Yields section (Table 3). The acreage

figures from the first row are entered only once. In other words,

the acreage distribution is the same for both harvesting methods

for comparison purposes.

The gross tons per acre, trash content, and sucrose content

of plant cane and each of the ratoon crops are required to

calculate net tons, standard tons and total gross tons to be

harvested. The differences between both methods are important

factors to determine the amount and quality of the cane delivered

to the mill.

In summary, the user must enter: first, the number of net

acres devoted to the different stages of production; second, the

yield in gross tons per acre, percent trash and percent sucrose

figures related to the mechanical method; finally, yields, trash

and sucrose for the hand cut method. The remaining figures (net

tons, standard tons and gross tons to be harvested) are

calculated by the program.

To see the results from these entries, press the {F91

recalculation key. It is important to note the difference between

the GROSS TONS TO BE HARVESTED of the alternative methods since

this difference will affect the cost of harvesting, hauling and

grinding the cane.



Tonnage to Handle

This section estimates total gross, net, and standard tons

for the plant cane and for each ratoon crop for both harvesting

methods (Table 4). To reach this section, press Z to return
13












to the Screen Access Menu and select number 3. After doing so,

the program automatically recalculates the worksheet. Notice

that the total gross tons figures are the same under GROSS TONS

TO BE HARVESTED of the previous section.

This section does not require any data entry. It is

presented for analytical purposes. Its main objective is to

provide users with information related to the tonnage to be

handled throughout the harvesting season.



Mahinery Owner shi2_and _QeratingostsMechanical Method

Selecting number 4 from the Screen Access Menu reaches this

section (Table 5). The user needs to specify the purchase cost of

the machinery or the initial total investment (if more than one

unit is required) and the amount spent on fuel, including

gasoli-ne, oil and lubricants in dollars per harvesting season.

This information interacts with other sections of the

spreadsheet to estimate harvesting costs, total costs and

returns. Annual fixed costs include depreciation, interest

charges, repairs, taxes and insurance. The straight line

depreciation method is used assuming a normal useful service life

of 10 years and a salvage value of 10% of the purchase cost. The

formula is the initial investment minus the salvage value divided

by the useful life of the machine. Interest charges are calculated

ias the average value (new cost plus salvage value divided by two)

of the item multiplied by the interest rate for machinery loans

and divided by two in order to account for a six month period.

Repairs are estimated at 16% of the initial investment. Taxes and
14












insurance are estimated at 3.5% of the average value of the

machine.

The machinery ownership and operating costs section presents

valuable information at the bottom of the screen. First, the

program adds all the above costs presenting total machinery

investment and subtotals for fuel, depreciation, repairs,

interests, taxes and insurance categories. It then divides these

subtotals by the GROSS TONS TO BE HARVESTED to provide a cost per

gross ton. The last two lines summarize total costs and total

costs per gross ton. These figures are presented for comparison

purposes. If the user wishes to see the results immediately after

entering this information, the {F9) key must be pressed to

recalculate the worksheet. If the user has better cost estimates,

the values calculated can be replaced by simply entering the

figure after unprotecting the formula.



Machinery_ OwnershiBand_QQeratiaCgosts: Hand-Cut Method

This section can be reached by selecting number 5 from the

Screen Access Menu (Table 6). The layout of this section is

identical to the previous one. Again, the user is required to

enter the purchase cost of the machinery or initial investment

and fuel consumption in dollars per year.

The information provided by the computer program in this

section is calculated using the same formulas and procedures as

those explained in the previous section. The only difference

between these two sections is the type of machinery employed to

harvest sugarcane. Press the CF9} key to see the recalculated

15












results.

The results provided by these two sections can be compared to

observe the different investment requirements for the alternative

harvesting methods. Machinery ownership and operating costs in a

total or a per gross ton basis can also be compared. Notice the

difference in total costs per gross ton between the two

harvesting methods.



Labor Use for Hand and Mechanical Harvesting

To reach this section, select number 6 from the Screen

Access Menu (Table 7). The first column describes the type of

job performed. The user needs to enter the wage rate, in

dollars per hour, for each employee and then the total number of

hours required for each type of job during the harvesting season

for both harvesting methods. Each wage rate entered must include

fringe benefits. The total number of hours required must be

entered under the "Use" columns.

The program calculates estimated labor cost for each type

of job, total labor use and costs, and total labor costs per

gross ton in the following manner: (a) total number of hours

required to perform a specific task are multiplied by the

employee's wage rate to obtain the cost of each task; (b) these

costs are added to arrive at a total figure; (c) total labor

use from all categories are summed to show total number of

hours; and (d) both total labor use and total costs are divided

by total gross tons to express them on a per gross ton basis.

The -{F'} key should be pressed to see the recalculated results.
16














REVENUE, COSTS AND RETURNS

No more data are required beyond this point. The rest of the

figures are automatically calculated by the program. The following

sections related to revenues, costs and returns are the results

from previous entries. The program provides results in absolute

and relative figures. The relative results are expressed in

terms of dollars per acre and dollars per net ton.

Revenues, costs and returns are the most important parts of

this software. There are different payment systems and degrees

of vertical integration in the industry. Three different scenarios

are presented in this section. "The user should concentrate on the

scenario that is relevant to his operation. For example, most

independent producers and cooperative members are not penalized

for extra processing costs due to fiber content, while this

cost is important to those producers of administration cane. The

user should be able to determine, not only which harvesting

method is less costly, but also which method provides greater net

returns. For example, with the figures used in the example run,

the mechanical harvesting method presents a cost advantage when

milling costs are not considered but this cost advantage is more

than offset by the lower revenues obtained after processing.



G3rowinq and Harvesting

These figures are summarized in Table S. This information is

derived from calculations made in previous sections, and can be

reached by selecting number 7 from the Screen Access Menu.

17












Revenues are divided into sugarcane sales and molasses

payments. Sugarcane sales are estimated by multiplying total

standard tons of cane delivered times the price per standard ton

in the general information section. Independent producers and

cooperative members receive a "molasses payment" from the mill

representing their share of the revenue from molasses sales. The

molasses payment is based on net tons delivered, the average price

of molasses, the expected or actual molasses yield coefficient and

the proportional share to be paid to the grower. All the

information required to do the calculations was entered by the

user or generated by the program.

The estimated growing cost was previously entered by the

user in the general information section. The harvesting costs

come from Tables 2, 3 and 4.

A summary of total costs and net returns is presented in the

last two rows of Table 8. It can be useful to compare the

relative importance of fixed (machinery) and variable costs

(production and labor) between the two different harvesting

methods.



Hauling _and ProcessinQ

Selecting number 8 from the Screen Access Menu will take the

user to this section, designed to evaluate the costs and returns

of a sugar mill that processes the cane delivered by other

growers (Table 9). Revenues are divided into raw sugar and

molasses sales. Raw sugar sales are calculated by multiplying the

average commercial recoverable sugar per net ton times the price
18












of raw sugar per pound and times the total number of net tons

harvested. Molasses sales are estimated in the following manner:

total net tons times the average molasses yield (gallons/net ton),

resulting in the total gallons of molasses which is multiplied

by the price of the molasses.

Total costs are divided into transportation, mill operation,

cane purchases and molasses payments. The transportation cost is

estimated by multiplying total gross tons to be harvested by

the cost of hauling from field to mill in terms of dollars

per gross ton. Milling costs are estimated as follows: the hand

cut cost is simply the cost of processing one net ton multiplied

by the amount of net tons delivered to the mill. The program

accounts for the difference in fiber content due to mechanical

harvesting by proportionally reducing the grinding capacity and

proportionally increasing the milling costs in relation to the

hand cut method.

The figures for cane purchases and molasses payments are

derived from the revenues in the growing and harvesting section

(Table 8). In other words, what represents a revenue for the

grower is a cost to the processor.





Up to this point, the growing and harvesting have been

analyzed separately in relation to the hauling and processing. In

order to have the total picture of the whole operation, the

combined net returns from both harvesting methods are presented in

Table 10, which can be reached by selecting number 9 from the
19












Screen Access Menu.

This section is designed to test the profitability from

harvesting sugarcane under both methods and to evaluate the

effect of the two methods on net returns for a sugar mill

processing its own cane --the mill processes only its -own cane

and not that of other producers.

Revenues, hauling, and processing costs are derived from

the previous section (Table 9). Growing and harvesting costs are

derived from the growing and harvesting sections.

The net return results are related to machinery costs,

inputs used, input and product prices, performance rates, etc. If

changes in factor or output prices occur, the figures entered

can be changed to evaluate the impact of these changes on net

returns. Once the new figures are entered, invoking the Z

command will make the program to recalculate the entire

worksheet.

The user can benefit from analyzing the results of different

scenarios. The figures in the General Information section can be

changed to observe their impact on the costs and returns.



SAVING AND PRINTING THE WORKSHEET

To save the worksheet, the user should press the usual 1-2-3

command (/File Save) and the name AUTO123 of the distribution

disk will be displayed on the screen. The user can replace the

old file with the same name or cancel the command. If the user

has any questions, the Lotus 1-2-3 manual should be consulted.

To print the corresponding reports, the program takes

20












advantage of the alternative typing facility or "macros" of the

Lotus 1-2-3 package. For printing reports, press P and a

Menu will appear on the top of the screen. Then press the arrow

keys to move the cell pointer to the section of the menu

you wish to print. If the user wishes to print the entire

worksheet, then the letter E must be entered. If the printer is

on, it will start printing the results of the analysis. If the

printer is off, the machine will beep and a printer error message

will be displayed on the bottom of the screen. Pressing the

or the keys will clear the upper section of the screen.

If the user wants to interrupt printing, the

keys must 4e pressed. The print command is also canceled before

printing starts by pressing the same keys.
