Soil Sampling

Soil Sampling


Know Your Soil

Soil sampling is used to determine soil fertility in order to apply nutrients for plant growth in an environmentally and economically sound fashion. Under-apply nutrients, and yield and profit will suffer. Over-apply nutrients, and money is wasted and environmental issues such as phosphorus leaching can occur. Sampling also determines soil pH, which at it’s optimum will allow proper uptake of nutrients that are applied. Other soil factors such as micro nutrients and organic matter content can help with management decisions such as pop-up recommendations and herbicide use.


Customized sampling packages for your operation!

  • Grid sampling
  • Soil Type Sampling
  • Soil Management Zone Sampling

Grid Sampling
Grid sampling divides a field in to square grids, commonly 2.5 or 5 acre grids. Several samples are taken within each grid and combined to form a composite sample for each grid.
Grid Sample Map

Soil Type Sampling
Soil type sampling uses a soil type map from the NRCS to designate sampling zones. Several samples are taken within each soil type and then combined to form a composite sample for each soil type. Soil types with an area larger than 5 acres are broken up in to units of 5 acres or less.
Soil Type

Soil Management Zones
Soil management zones consist of a soil type map that is broken down even further in to atypical areas in the field. Changes in soil water retension, surface runoff, soil texture, soil structure, elevation and many more factors are isolated within soil types and treated as a seperate sample.
