Economics of Tile Plow Investment and Use

John Hanchar, Farm Business Management
Northwest New York Dairy, Livestock & Field Crops

July 8, 2013

In an article of the February 2011 issue of AgFocus, James Kingston reviewed the topic of tractor-drawn tile plows. The article utilized data from presentations that he made at the NWNY Dairy, Livestock, and Field Crops Program's 2011 Corn Congresses in January. In the article, James included a brief summary of some economic analyses that we developed to examine tile plow investment and use. The purpose of this article is to provide more detailed information from those economic analyses. For the detailed analyses, including the MS Excel Spreadsheet developed to examine tile investment and use, please visit the team's website at and click on "AgFocus."
SummaryPartial budget analyses for profit indicated that 16 of the 20 expected feet installed annually, expected tile contractor charge combinations yielded expected increases to profit (Table 1). Net present value analyses indicated that of 14 of the 20 expected feet installed annually, expected tile contractor charge combinations yielded net present values greater than 0. Net present values greater than or equal to 0 reflect capital investments that would be considered attractive to the producer (Table 2).
Refer to Table 1 below
Overall, analyses suggest that if a producer can expect to install about 16,000 feet of tile or more annually over 5 years, then investment and use of a tractor pulled tile plow is attractive given expected contractor charges of about $0.65 per foot or greater.
Refer to Table 2 below

Considering Costs to the Producer of Realizing Savings in Contractor ChargesA review of information sources prior to developing the economic analyses produced material that enthusiastically described the money that can be made using owned machinery and labor versus hiring a contractor. One example noted $4,000 made in one afternoon ($0.50 per foot excluding tile, the contractor charge avoided, times 8,000 feet installed). Although the savings are notable, the analysis seems to ignore that a farmer would expect to incur additional ownership costs (depreciation, interest, insurance and others) and operating costs (hired labor, machinery repairs and maintenance, fuel, oil and lube expense, and others) associated with tile plow investment and use. The purpose of our analysis was to evaluate the expected benefits and costs associated with tile plow investment and use. An important assumption for all of the analyses described below is that the decision to tile has already been made - expected benefits exceeded expected costs. The only decision remaining is whether to have tile installed by a contractor, or install tile using owned equipment and labor supplied by the farm.
Partial Budget AnalysisA partial budget projects the expected change in profit associated with a proposed change in the farm business, for example, investment in and use of a tile plow compared to hiring a contractor. The expected change in profit equals the expected change in total value of production, income minus the expected change in the costs of inputs used in production. With regards to tiling, expected cost savings might be considerable. However, what cost increases will the farmer incur to realize these savings? A partial budget considers all expected changes to income and costs ?? the decreases and the increases.<br><br>Net 
Present Value AnalysisNet present value analysis considers the time value of a stream of net cash flows, income over the life of the investment. The time value of money concept results from the fact that individuals, when given the choice, would prefer to receive a dollar today over a dollar received at some future date, for example, a year from now. The net present value of an investment is the sum of the present values for each year's net cash flow less the initial cost of the investment. If the net present value of an investment is greater than or equal to zero, then the investment is attractive to the decision maker. For this analysis, the initial cost of the investment was $33,000 for the tile plow, stringer cart, and control system.
The analyses described here focused on expected changes in profit and net present values of the investment. James' February article mentioned other considerations that help to determine whether tile plow investment and use makes sense for an individual operation.

Come join us on July 23 in Seneca County at Quinten Good's farm for a demonstration and walking tour of 16 different pre- and post-emergence treatments in soybean and 12 different treatments and combinations in corn.
  • Tall waterhemp and marestail are two weeds that are resistant to glyphosate and ALS herbicide modes of action in the WNY and Finger Lakes regions.
  • Each year the number of acres with resistant weed populations expands.
  • For herbicides to be an effective tool in weed management, we have to know what chemistries & application timings are most effective against these resistant weeds.

RMA Announces Additional One-time Changes to Prevented Planting Provisions

RMA Announces Additional One-time Changes to Prevented Planting Provisions
for 2019 Crop Year

In response to delayed and prevented planting resulting from above average rainfall and wetness, the USDA Risk Management Agency has made a one-time change to the 2019 crop year prevented planting rules that effectively allows silage corn, if planted as a cover crop following local agricultural expert guidelines, to be acceptable as a post-prevented planting cover crop. Under this one-time rule change, producers are allowed to produce this crop while retaining their prevented planting payment. This change couples with previously announced one-time changes to the prevented planting rules - including expanded acceptable uses for post-prevented planting cover crops and a change in the cover crop haying and grazing start date rule - serve to help those struggling to meet their forage needs due to the weather.

Read the full article from the New York Crop Insurance Education Program.

The USDA-RMA states that "For crop insurance purposes, a cover crop is a crop generally recognized by agricultural experts as agronomically sound for the area for erosion control or other purposes related to conservation or soil improvement." PRO-DAIRY specialists Joe Lawrence and Karl Czymmek and Dr. Quirine Ketterings, Professor and Director of Cornell Nutrient Management Spear Program have released a letter stating "Corn on Prevented Planting acres meets these objectives."
