Get Bigger Yields with Soil Sampling

Yield Map

High-stress growing seasons increase crop production variability throughout the field, making it more important to plan for next year with soil sampling. 

Your yield monitor offers a lot of insights that can be confirmed with a variety of soil sampling options. With soil samples, your Landus Cooperative Field Sales Agronomist can recommend the right amount of fertilizer with our Variable Rate-Crop Removal Fertilizer Recommendations. Your yield data allows us to help you take a deeper dive using our zone management toolbox. These zones allow your agronomist to better manage fertilizer and seed inputs on your hilltops versus the depressions as well as the high yielding areas versus the lower-yielding areas of your farms. This will ensure you a better return on your fertilizer and seed inputs, knowing that they were placed as the right source, on the right acre, at the right rate, at the right time. 

Standard Grid Soil Sampling 

Grid sampling is a simple and unbiased method for site-specific soil management. After soil samples are pulled, georeferenced, and analyzed, a map is created by assigning soil test values to a grid, revealing soil nutrient levels and variability. With georeferencing grid soil samples, Landus Cooperative ensures that your grid soil samples will be sampled from the same field locations every time.

Grid Size

Grid size typically depends on economics and desired variability. Smaller grid sizes provide a better understanding of variation throughout a field, while larger grids may be more economical.

Grid sizes offered by Landus Cooperative include 2.5 acre grids, 4.4 acre grids, and 10.0 acre grids. While standard grid sampling ensures consistent sampling procedures while revealing variability among soil nutrient values, there are still variabilities throughout a field that grid sampling does not capture. Variabilities that have a direct effect on yield. These variabilities include soil type, elevation, and crop yield potential.

Hybridized Grid Soil Sampling 

Hybridized grids take grid data and overlay it on top of a zone map. The creation of a Landus Cooperative zone map takes these additional variabilities into account. Hybridized grids can be used to gain more information and intensify management across your farm.

Benefits of Hybridized Grid Sampling 

  • Applicable with any grid size
  • Ability to move grid points into management zones to increase management practices
  • Set variable yield goals throughout field
  • Use existing grid soil sample data to intensify management

Manure Management Compliant 

Growers today are challenged to protect resources, while also maintaining crop and animal production. As a result, there is an urgent need to develop, adapt, and innovate when it comes to manure management technologies and practices.

Hybridized grids help minimize over-application of manure in areas of the field with higher nutrient values. This approach is useful for growers who utilize grid soil sample results but have not yet implemented variable yield goals behind their grids. Doing so results in a much higher level of field management.
