Is there an excess level of fertilizer that prohibits a yield benefit from BiOWiSH agronomy products?
Excess fertilizer application negatively impacts soil, affecting root systems (which supply water and nutrients to the plant) and overall plant growth. Excess fertilizer application also creates situations where the excess fertilizer cannot be naturally dissolved by rainfall or irrigation water, resulting in the soluble salts and minerals remaining in the soil. This raises soil salinity levels and can lower soil pH, making nutrients less available to plants. In these extraordinary circumstances these factors accumulate and can reduce the efficiency response of BiOWiSH agronomy products, as well as negatively affecting native beneficial soil microorganisms.
