Understanding Soil Carbon Dynamics

Carbon is an often overlooked, but very important com­ponent of the soil. We know how to manage nitrogen, phos­phorus and potassium for maximum production, and that micronutrients play a critical role in crop yield and disease resistance. Deficiencies can usually be corrected relatively quickly through the addition of soil or foliar fertilizer ap­plications. While soil […]

We knew then, and know even more now, that plant stress is a very significant yield-and-quality-robbing factor in agricultural crops to which little attention has been paid. We […]
