NEW MACHINERY COST ESTIMATES AND PLANTING COST
New machinery cost estimates were released on farmdoc in
June 2003. These cost estimates are calculated using an economic-engineering
approach based on buying new equipment and holding all machines,
except combines, for ten years (combines are held for seven years).
Estimates for tractor, field, planting, forage, and combining operations
are in the management section of farmdoc (click here).
In addition, online Machinery
Costs Tools are available that allow users to change input
so that costs more closely reflect operations on a particular farm.
Costs of Split-row Planters
A new planting operation was added to the 2003 cost estimates to
account for costs on split-row planters. The split-row planter's
costs are based on a "conventional" machine that has 30-inch
rows for planting corn. Rows are added when planting soybeans so
that row spacing is reduced to 15 inches. The split-rows are only
used on soybeans so that additional costs associated with the split-rows
are allocated only to soybean acres. Hence, the reported costs for
split-row planters are only applicable to soybean acres. Costs for
corn acres are based on a "conventional" machine.
The publication lists the costs for an 8-row conventional planter
as $8.10 per acre and the costs of a split-row planter as $11.80
per acre (see Panel A of Table 1). These costs are calculated assuming
that the 8-row planter covers 800 corn and soybean acres and the
split-rows are used on 400 soybean acres (i.e., an assumption of
a 50-50 corn-soybean rotation is made when calculating acres). The
split-row planter includes costs for the base unit ($27,600 of new
investment) plus costs for the split-rows ($12,200 of new investment).
An 800 acre farm that has a split-row planter would use the conventional
planter estimate for corn ($8.10 per acre) and the split-row planter
for soybeans ($11.80 per acre). Average costs over the entire 800
acres are $9.95 (i.e., (8.10 + 11.80) / 2).
Planting System Costs
Costs contained within these publications can be used to compare
the costs of different planting systems. For example, Panel B show
costs for planting equipment that is typically used on a 1,200 acre
farm planting 600 acres of corn and 600 acres of soybeans. Based
on estimates in Panel B, the costs of the following three planting
1. Plant both corn and soybean acres with a 12-row planter having
30-inch rows. Costs for all corn and soybean acres are based on
the conventional planter and equal $7.70 (Panel B of Table 1).
2. Plant corn with a 12-row planter and plant soybeans with split-rows.
In this case, per acre costs for corn are $7.70 (Panel B of Table
1), the costs associated with the conventional planter. Per acre
costs for soybeans are $10.90, the costs associated with the split-row
planter. Average costs over all corn and soybean acres equal $9.30.
3. Plant corn with a 12-row planter and plant soybeans with a drill.
The costs of using a conventional 12-row planter for 600 corn acres
are estimated at $10.68. This estimate was obtained using Machinery
Cost Tool available online at farmdoc. The Tool contains
defaults used for calculating costs for a 12-row planter covering
1,200 acre. The 1,200 acres covered default was changed to 600 acres
in order to arrive at per acres costs of $10.68. The average costs
over all corn and soybean acres are the average of the corn and
soybean costs and equal $10.19.
Planting soybeans with a split-row planter or a drill is more expensive
compared to planting all acres with a conventional planter. This
occurs primarily because the system with only the conventional planter
has lower investment than the other systems. Most likely, the additional
costs associated with the split-row or drill systems would have
to result in higher yields before the split-row or drill systems
are economical compared to the one planter system.
New machinery cost estimates have been released. These costs are
useful for a number of purposes including setting custom rates and
examining planting costs. The costs will vary depending on inputs
used in calculating costs. New Online Machinery Cost Tools allow
users to change inputs, thereby tailoring cost estimates more closely
to match a particular farming operation.
These costs often are used to set custom rates. When used for this
purpose, it is important to remember that the estimates only include
costs. An additional margin should be built in to cover profit.
