Enhancing plant health and vigor is accomplished through proper timing and placement of nutrients, and begins with a healthy soil. A fertile soil environment encourages uptake of nutrients, particularly if nutrients are available at planting time. Once appropriate soil structure is established, the next priority is to awaken microbial life.
The main nutrients needed by plants are: CHO, PKNSCaFe, MG, BMnCuZnMo. Calcium is an important fertilizer because it is required for proper functioning of cell membranes and cell walls. It is specifically need in large amounts at the tips of growing roots and shoots and in developing fruits, because relatively little calcium is transported in phloem.
Another important fertilizer is sulfur. Sulfur contains the amino acids methionine and cysteine which create protein. Sulfur also contains sulfolipids, which are the fatty compounds found in membranes, especially chloroplast membranes.
Gypsum has been shown to reduce soil erosion, which allows crops to retain the nutrients that they need to grow. The key to having fertile soil is remembering that everything works best in balance, and having the right balance of nutrients will give your plant the energy it needs to grow.
