Soil Texture Mapping

Current digitized soil maps were hand drawn over the coarse of the last century.  This information was gathered by walking over the land on observing the soil.  Your soil maps are only as accurate as the person many years ago perceived them to be.  Surprisingly, the soil maps do have a fair level of accuracy associated with them.  GPS signal available today has surpassed the accuracy of these hand drawn maps.  Newer technology has emerged and is allowing for the mapping of soil textures several feet below the surface.  This method is called EC or Electrical Conductivity and is foundational information to the building of Management Zones.  This is crucial information for Soil Sampling, Variable Rate Seeding, Multi Hybrids Planting, and Nitrogen Management.  By increasing the accuracy of soil maps, variable rating products across your fields will increase the productivity which leads to an increase in your bottom line.

Organic Matter Mapping

A newer phrase being tossed around today is Soil Health.  One of the key components of soil health is organic matter.  Two of the main sources of organic matter today are decomposing crop residue and manure.  Living organisms in the soil called Microbes feed upon residue and manure recycling it back into plant food.  Organic Matter has several highly important attributes that make it critical to for variable rate success.  Two of them attributes being; mineralized nitrogen, and Water Holding Capacity.  Natural occurring nitrogen is a by product of the Microbes breaking down crop residue.  Organic Matter varies across across a field, resulting in variable rates of organic nitrogen existing in your fields.  Mapping Organic Matter allows for application of variable rate nitrogen.  The second attribute of importance to understand about Organic Matter is the additional water holding capacity.  Water is an important natural resource for crop production.  Creation of variable rate seeding maps need to take water holding capacity into account to sustain the seed population assigned to that management zone.   Mapping of organic matter is highly crucial to the success of variable rate seeding and variable rate nitrogen.  Knowing this information on where to adjust seeding rate based on water holding capacity and nitrogen allows for the increase in yield.  More bushels to sell equates to higher profitability.
