The nutrients, like potassium, calcium, phosphorus, etc., can be added to the soil and plants by using chemical fertilizers. These are synthetic, man-made fertilizers that also make the soil fertile. These chemicals can be used as per the instructions for crops that need to be big and healthy. Composed of non-organic elements, these are water soluble and can be sprayed using a spray gun. Not just potassium humate, calcium nitrate, potassium chloride and other chemical fertilizers work faster, but have longer shelf life in comparison to bio fertilizers. When applied, these fertilizers equally distribute the essential nutrients.
