Products / Fertilizer What's Fertilizer
Fertilizers (also spelled fertilisers) are compounds given to plants to promote growth; they are usually applied either via the soil, for uptake by plant roots, or by foliar feeding, for uptake through leaves. Fertilizers can be organic, or inorganic which made of simple, inorganic chemicals or minerals. They can be naturally occurring compounds such as peat or mineral deposits, or manufactured through natural processes such as composting or chemical processes. Fertilizers typically provide, in varying proportions , the three major plant nutrients nitrogen , phosphorus, and potassium. The secondary plant nutrients calcium, sulfur, magnesium, and sometimes trace elements or micronutrients with a role in plant nutrition: boron, chlorine, manganese, iron, zinc, copper, and molybdenum . In the past, both organic and inorganic fertilizers were called "manures," but this term is now mostly restricted to man-made manure.
