Application Tactics.

While crop nutrients exist naturally in the soil, atmosphere and animal manure, naturally occurring nutrients are not always available in the forms plants can use. Manufactured crop nutrients contain the same ingredients as natural ones.Nitrogen (N), phosphorus (P) and potassium (K) are three primary nutrients required by all forms of plant life. N fosters rapid, leafy green growth and builds plant material; P assists with production of seeds and root growth; and K advances fruit quality and boosts disease resistance.We recommend best management practices that ensure crop nutrients are applied in the proper amounts for high yields and protection of the environment. Soil sampling, nutrient management programs and Global Positioning System (GPS) technology help determine the best application levels. And Variable Rate Technology (VRT) helps ensure economical and ecologically sound product applications are made by adjusting crop treatments to meet the varying conditions within each field.
