Soil Testing

AGVISE Laboratories has 21 years of experience in soil testing. Soil testing is a process for evaluating the level of available nutrients and physical characteristics of soil samples. Soil samples are collected from representative areas of fields and then delivered to one of our laboratories for analysis. The laboratory analysis is completed within 48-72 hours and then sent to customers via E-mail, telecommunication, FAX, mail, etc. This soil test data is used to determine the rate of each nutrient required for the desired crop and yield goal requested by our customers.

Grid Soil Testing

Grid soil testing is one sampling procedure for evaluating the variability of nutrients within fields. This is accomplished by dividing the fields into small pieces or “grids”. These grids are then sampled and analyzed separately. The soil test data from each grid soil sample is then transferred via telecommunication to our customer’s computer. This data is then used to create maps, which control the rate of applied nutrients on each grid.

AGVISE routinely tests the following parameters on grid fields and commercial fields:

  • Nitrate-Nitrogen
  • Ammonia-Nitrogen
  • Phosphorus
  • Potassium
  • % Organic Matter
  • pH
  • Buffer pH
  • Zinc
  • Copper
  • Iron
  • Manganese
  • Boron
  • Chloride
  • % Soil Moisture
  • % Sand, Silt, Clay
  • Soil Bulk Density
  • Water Holding Capacity (Wilting Point, Field Capacity)
  • Water Soluble P, K, Ca, Mg, Na & S
