The disadvantage of a solid fertilizer is that during the dissolution of the fertilizer salts prior to foliar application the lowering of the solution temperature may affect the solubility of some salts.This is avoided if a true solution such as Wuxal is used since all the nutrient salts have already been dissolved during its formulation.Wuxal also contains a phosphate buffer which improves the affinity of nutrients to the plant leaf tissue.The buffer maintains the required pH value in the tissue for anoptimum uptake of P by the plant.The relative amounts of N components in a liquid fertilizer may have an adverse effect on up-take of Ca, Mg, and microelements by the plant.Wuxal acted beneficially on nutrient uptake by the plant.
