Figure 2. Plants take in calcium along with water through their roots, so the . Antacid tablets are made of calcium carbnate (CaCO3). For a grain crop, adequate calcium can help to prevent lodging as the Without the proper supply and intake of calcium, plants can develop conditions such as blossom end rot. • Calcium is a direct nutrient to growing plants and soil life. Therefore, it is necessary to * The tablets supposed to be given to humans have Iron, Calcium, Magnesium etc in the form of suitable salts like Ferrous Sulphate etc. The calcium can be absorbed through the roots, or in the leaves as a foliar spray, and works to strengthen cell walls to prevent cracking, as well as cure/prevent blossom end Many of these minerals are found in multivitamins manufactured for human use. The salts may further be in complex association with other organic molecules and Tomato plants can suffer from calcium, magnesium, potassium, iron and manganese deficiencies just like humans can. Plants and animals have some of the same nutritional needs. Use a mulch like pine straw, dead ground leaves or straw and cover the planting site with approximately a 2 inch layer. Refrain from severe pruning of the tomato plants, as severely pruned plants are more likely to experience 3 UH–CTAHR Natural Farming ater-Soluble Calcium SA-10 Dec. 2013 Figure 1. Plants use calcium to build cell walls and membranes. Remove inner egg membrane from the shell prior to roasting. Among other benefits, it is essential to healthy cell walls, affecting both permeability and strength. Since calcium mobility in plants is limited, calcium deficiency will appear in younger leaves (die back or burns) and in fruits (blossom end rot, bitter pit), because they have a very low transpiration rate. Collect any poultry eggshells (oys - ter and clam shells may also be used).
