Manure and Fertilizers

Have you ever tried growing a plant in your garden? You did everything correctly, you gave it water and kept it in sunlight. And yet, it did not grow. What did you do wrong? Do you just not have a green thumb? Or was it perhaps that the plant needed manure and fertilizers? Let us learn more about them.

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.

Answer 2

Manures are natural agricultural waste which can be useful for helping plants grow and giving them nutrients.
Ex: compost, dry leaves, cow dung etc.

Fertilisers are chemical and many farmers use it in normal food. While growing organic food, farmers do not use fertilisers because it is chemical.
