It all starts with the soil. It takes about 300 years to form 3/8 inch of soil in a mild climate. The soils we farm were formed over thousands of years, and if managed well that same soil will be around for generations to come.
Soil texture does not change; which is why Veris EC or Geonics EM38 soil mapping are typically one time operations. Good or bad we can expect to farm the same soil texture as long as we remain stewards of that land.
“It makes sense to understand a resource that is relied on for a lifetime.”
Both Veris EC mapping and EM38 soil mapping leverage the soils ability to conduct electricity. The soils conductivity is related to the particle size, soil moisture, and salt content. By measuring and mapping the differences in the soil ec we can differentiate between soil textures, e.g. clay’s conductivity is higher than sands. Properly calibrated, these soil sensors are also capable of mapping variations in soil salinity.
The soil affects everything, from seed to fertilizer to herbicides. A one time investment in soil texture mapping gives a better understanding of the crops underlying resource. This information has the potential to yield dividends year in and year out because the layer has no expiration date.
