excessive use of inorganic fertilizers

Fertilizers are a class of synthetic chemicals supplied to crops in order to increase their growth and yield. Important fertilizers used in agriculture include urea, dia-ammonium phoshate, muraite of potash (potassium chloride), potassium sulphate, gypsum (calcium sulp..

The fertility of the topsoil can be restored by taking the following measures. a) Regular use of manures and fertilizers can replenish the minerals used by the crops. Green manuring can also be done. b) Crop rotation should be practiced c) New techniques of ..

Chemical Fertilizers - These are nutrient supplements for plants manufactured in fertilizer factories from chemicals. They are nutrient specific i.e., they may provide only nitrogen, only phosphorus or only potassium to the soil. They are often used when a particular n..
