Once again, given its limited mobility in the soil, it is commonly applied directly to the deficient organ, for example, calcium chloride can be applied to the fruit. One of our first goals should be balancing the calcium to magnesium and phosphate to potash ratios. The reason is that calcium from calcium nitrate and phosphate from ammonium phosphate in the complete fertilizer may form calcium phosphate, which is insoluble in water. Consequently, calcium is normally applied in its soluble form as a foliar fertilizer. It is treated with acid which breaks down the crystal and produces soluble phosphate.

It’s contact with the root is by mass flow, which means it requires water. Hydroxyapatite was of very low availability on all soils. Too much water can cause leaching and also damage the roots, and not enough water can prevent the mass flow. Phosphorus as an essential nutrient for crops is widely applied in agriculture by a chemical phosphorus fertilizer (CPF), while, globally, phosphate rocks available for CPF production are limited and rapidly being depleted. The basis of phosphate fertilizer is phosphate rock, a crystalline calcium phosphate that is hard and insoluble. An example for such incompatibility is mixing fertilizers that contain calcium with those that contain phosphate or sulphate. Calcium nitrate on the other hand can damage the fruits if applied directly on it, so it is applied on the leaves, such as on tomato leaves. – Longitudinal chlorosis on the leaf edges This is more efficient than broadcasting and causes less root damage.
