advantages of using manure

Manures are organic materials added to the soil to increase crop production. They are biological in origin. The organic matter content is bulky and large and the nutrient content is small. They have the following effect on the soil. They supply nutrients to the soil. Since the manure..

. The latter system is followed in other short duration green manure crops - which are grown on cultivated lands. Most of green manure crops are leguminous and have capacity to fix nitrogen. Their use as green manure is advantageous - as this helps ..

Green manuring is the practice of growing and ploughing in, the green crops, into the soil. It is a cheap and effective method that increases soil fertility as it can supplement farmyard and other organic manures and is more cost effective. Green manures add nitrogen ..

This is the decomposed mixture of excreta (dung) and urine of farm animals like cow, horse, goat and sheep along with leftover hay and fodder. They are readymade manures and contain nitrogen, phosphorus and potassium. Farmyard manure when collected in the field and stored in an..

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..

It can be used to measure temperature accurately because of its electrical nature and a wide range of temperature difference(0.001K - 2000K) It absorbs a very small amount of heat from the object and therefore does not change the temperature to be measured. As the thermal capacity..

an indefinite number of plants can be raised from a small mass of parental tissue. It is useful for obtaining virus free healthy plants. An unlimited number of plants are produced within a relatively short time..

The demand for electricity varies at different times of a year. One big disadvantage is that the wind, waves and tides do not occur at all time and hence cannot guarantee steady production of electricity. Hydroelectric power stations can solve this problem. When the demand is low, excess power gene..

Applying bio-fertilizers and manures can reduce chemical fertilizer and pesticide use. Biological methods of pest control can also reduce the use of pesticides and thereby minimize soil pollutio..

1) Ammonium nitrate is used in the manufacture of fire works. 2) It is used in the preparation of explosives. 3) It is used as a fertilise..
