Mowers Soil Testing Plus, Inc. -- Field Services -- GPS Soil Sampling

Grid Soil Sampling

Based on some grid frequency, typically 2.5 or 3.3-acre grids. Soil cores are pulled near the center of the grid and the location is recorded using DGPS technology. The smaller the grid size, the more accurately you will be able to measure the variability of the nutrients within a given field. The soil analysis characterizes the current fertility and pH level of the soil. This is often a reflection more on past fertilizer applications and limestone treatments rather than on the natural characteristics of those soils.

Management Zone Sampling

Sampling pattern based upon some user-defined criteria. The criteria can be based on topography, past yield history, combinations of grid, soil types and management zone or others.

Soil Type Sampling

Soil types are characterized by physical factors, not chemical. Physical factors of a soil include the slope, parent material, surface soil thickness, organic matter, texture (% sand, silt, & clay), natural drainage and permeability. Sampling by soil type generally results in fewer soil samples and often does not properly represent a field unless a grid sampling method is applied to each soil type.

Our modern field equipment, up-to-date GPS receivers, and well-trained, professional operators will handle all your GPS sampling needs. We offer many field sampling and mapping services including custom GPS grid or management zone sampling, tile line mapping, field boundary mapping, seed production mapping, crop injury mapping, corn maze mapping, and field diagnostic service mapping.

Incremental Soil Sampling

Incremental soil sampling is sampling a field based upon a predetermined sampling pattern. This pattern may be based upon a grid frequency, soil types, grid management zones and any other type of user-defined management zone.
