Grid Sampling

Whether you need soil sampling for MMPs or VRT application, we can create a program to meet your needs. Typically 2.5 acre and 4.4 acre grids are recommended for fertilizer applications, while 10 acre grids are sufficient for DNR requirements in an MMP. Each fields maps are put in a fertility book, along with printouts for each nutrient tested that explains some characteristics of that nutrient and how it reacts in the soil. Some sample maps are displayed below. 

Benefits of working with Precision Management...

  • All sampling programs and packages can be customized to fit your operation's needs.
  • Ability for you to have samples analyzed by whichever soil lab you prefer.
  • Very efficient turn-around time.
  • Personal working relationship. You will feel as if we are an employee of yours.
  • Quality of work done in the field. We truly understand how important it is to take effective samples. We sample all fields as if they are our own.
  • Quality of our maps & reports. We present the data in a format that is easy read and understand.
  • Option for you to have all maps, reports, and data files posted in your account online. This means you can log on anytime, from anywhere to see your data.
  • We can do everything from sampling the field to making a VRT spread file for virtually any controller on the market.
  • Above all, we want to see your operation be successful. Our success depends on yours.

How a field is Grid Sampled...

To begin sampling a field by grids, the operator drives around the boundary of the field with an ATV equipped with GPS. The computer is logging the boundary while it is being driven. The completed field boundary will show on the computer screen with the exact acres within the field.  The computer will then ask which size of grids to divide the field into. This particular field was sampled using 4.4 acre grids. The computer equipped with GPS will guide the operator to each sample location within the field, where a sample is taken and sent into the lab for analyzing. The sample consists of taking many cores in a radius around each sample point. Once the soil is analyzed, the results are imported into our GIS program and fertility maps are generated.  The following maps are some examples of the grid sampling method.
