Are there any crops or types of soil where EF Polymer cannot be used?
At present, EF Polymer can be used with any crop and in any type of soil. Even in poorly drained soils, the expansion and contraction of the polymer creates air pockets within the soil. This process helps oxygen reach the roots and provides habitats for microorganisms, which can positively influence both plant growth and soil health.
I would like to hear the voices of farmers who actually use it.
