They are also called chemical fertilisers, artificial fertilisers or inorganic fertiliser. They include: simple mineral fertilisers such as urea, ammonium nitrate and sulphate.

Detailed explanation-3: -Fertilizers are labeled with three numbers, giving the percentage (by weight) of nitrogen (N), phosphorus (P), and potassium (K). This is referred to as the fertilizer grade. The remainder of the ingredients are fertilizer carriers such as sand or ground limestone, and sometimes micronutrients.
