definition of organic fertilizers

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..

The farm yard manure or organic manure or bio fertilizers and inorganic fertilizers supply the necessary plant nutrients to the soil. Thus, application of such materials increases the nutrient value of the soi..

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 ce..

. The generative cell divides and produces two male gametes while the tube cell disappears. After reaching the ovary, the pollen tube enters into the ovule. Depending upon its place of entry, three types of fertilization have been recognised. They are..

Introduction - Organic chemistry is that branch of chemistry which deals with the study of compounds of carbon with hydrogen (hydrocarbons), and their derivatives. Presently about five million organic compounds are known. Since the synthesis of urea from ammonium thiocyanate, ma..

An organism, may be small unicellular or multicellular. Organisms have a fixed life span and organised life cycle comprising of birth, growth, maturity, old age and death. They are always derived from pre-existing ones through the mechanism of reproduction. The offspring resemb..

Continuous addition of fertilizers without any regard to its dosage, balance between nutrients and requirement of crops has caused loss of fertility - although fertilizers are supplied to improve the nutrient status of soil. Soil has been rendered by modern method of ..
