Improving Agronomic Profitability through ProTech Analysis
A common question among growers is "What do we do with all of these years worth of yield Maps?"
Yield history is extremely important and useful. The historic yield maps assist us in bench marking and creating mgmt zones, building variable rate planting maps, building N maps, and building fertilizer maps. We really do use all of those old yield files that you have logged and filed away for years and years.
Soil Test Data
Part of the data management is keeping track of all the soil tests and how it relates to yield. We sample every 3 to 4 years and use each sampling cycle as a benchmark against the previous year. Keeping all of this information helps us determine the direction we need to go on fertilizer recommendations and whether we are raising or lowering soil test values. The goal is to raise soil test values to the optimum level with regards to production potential.
We are able to look at our soil test data and see how the soil test correlates to yield in each management zone of the field. This helps us determine the optimum fertility for the most productive portions of the field as well determining the optimum fertility for the least productive portions of the field.
As Applied Data
The as applied, geo-referenced, data is extremely important to us. We want to record everything that is being done in the field. All of the as applied information such as hybrids, rates, yield, and singulation are all read and put into our database. Using the as applied information in combination with soil test results helps us determine how each variable may affect one another and ultimately how it affects yield.
Field History With Costs
The Field History reports give all the information pertaining to a particular field. This would include for example the crop, planting date, tillage type, effect of fertility on yield, chemical and fertilizer applications, plus a break down of the cost of production in cost/ac and cost/bu format. All field history sheets can easily be printed off the website in a batch print.
