organic fertilizers phosphorus

Constant use of the soil leads to the loss of its important nutrients particularly nitrogen, phosphorus and potassium and thus the soil loses its fertility. For the healthy growth of the plant these deficiencies in the soil have to be replenished with the use of certain material..

The amount of phosphorus present in any organic compound is determined by Carius metho..

1) Some amount of phosphorus is returned to earth in the form of birds excreta - Guano deposits (excreta of marine birds) and dead fish (around 60,000 tonnes which is less than 0.5% of phosphorus discharged from rivers). 2) Death and decay of organisms and decompositi..

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 nutrient is required in the ..

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 applying water benea..

Occurrence and Uses of Phosphorus - Phosphorus is widely distributed in nature. It does not occur in free state since it can be very easily oxidised. It is usually present in rocks in the combined state as phosphates. The main phosphate rocks are: Phosphorite: Ca 3 (PO 4 ) 2 Flu..
