In segment two of figures one and a couple of, you will discover pH, P, K, and Mg concentrations represented by a numerical worth and also a bar chart describing them as underneath ideal, the best possible, and above the best possible. The calculated soil fertility values are nothing at all without the need of research on how crops react underneath different soil fertility problems. Researchers exam crop reaction to nutrient additions and build curves, Impression three. When soil exam ranges are under the the best possible, there is a greater opportunity the crop will respond to supplemental nutrient offer, positively impacting development and production.
