Answer 1

Answer:

We know that plants need certain essentials to grow and nurture. Water and sunlight are the obvious ones. However, plants also need certain nutrients (like nitrate, magnesium, etc) which it absorbs from the soil. But say your soil is lacking in certain minerals that these plants require for growth. Then these minerals and nutrients must be added to the soil to make it fertile. So we add manure and fertilizers which compensate for the infertility of the soil.

Manure

Manure is a natural fertilizer. To make manure, decomposition of plants and animal waste is done by farmers. The product of this decomposition is a material rich in organic matter which we call manure. Manure does not have a high content of nutrients. Instead, it gives fertility to the soil by adding humus (an organic component of the soil). This improves the soil’s physical properties, with better retention of moisture and more aeration.

And since manure is made entirely of organic materials it does not contribute to any form of pollution. In fact, it reduces waste on the farm, by decomposing waste materials to make manure.
