Farming Practices Test - 2

Manure contains large quantities of organic matter.

Manure is an organic matter, mostly derived from animal faeces, except in the case of green manure, which can be used as an organic fertiliser in agriculture. Manures contribute to the fertility of the soil by adding organic matter and nutrients, such as nitrogen, that are trapped by bacteria in the soil.

Fertilisers only supply N (Nitrogen), P (Phosphorous) and K (Potassium).
Na (Sodium) is not generally supplied by fertilisers.

Decomposition is the process by which organic substances are broken down into simpler matter. Hence, the correct answer is: `Manure is prepared by decomposition of animal excreta and plant waste`.

Hybridisation is the process of crossing two genetically different individuals to result in a third individual with a different, often preferred, set of traits.

The practice of growing two or more crops simultaneously in a fixed pattern is known as intercropping.

Vermicomposting is a technique of converting decomposable organic wastes into valuable vermin compost through earthworm activity.

Pesticides are substances that are meant to control pests.

Weeds should be removed as they compete for food, space and light with the main crop, take up nutrients from the soil and reduce the yield of the main crop.

The inorganic substance which has three main elements present, i.e. nitrogen, phosphorus and potassium, is called a fertiliser.
