organic nitrogen fertilizers

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 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..

Introduction - Functional groups containing nitrogen are present in a variety of naturally occurring and man made organic compounds. These functional groups impart physico- chemical characteristics to these molecules. These groups are responsible for their unique chemical reacti..

Nitrogen forms nearly 78% of the volume of air. Earlier, the useful significance of nitrogen was not known and it was considered to be inactive. At that time, nitrogen was considered important only because it was known to moderate the processes of respiration and combu..

. Plants convert the inorganic nitrates to organic proteins. The proteins from the plants enter the body of animals in form of food. C) How is nitrogen returned to the soil? When plants and animals die their bodies decompose. The organic proteins undergo a series of ch..

Some bacteria are known to fix the atmospheric nitrogen for their own biological activity. This natural phenomena is commercially utilized to increase the nutrient supply to crops. There are two types of nitrogen fixing bacteria. They are a) Symbiotic N 2 fix..

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 ..
