When the soil is too basic, plants do not grow well in it. To improve its quality what must be added to the soil?.
Xelga [282]

Organic matter is added to basic soil to neutralize its base which improves its quality.

<h3>What is an organic matter for soil? </h3>

Manures are organic matter. These are the waste products of plants and animals that are used as sources of plant nutrients. After their decomposition, they release nutrients.

The practice of collecting and using wastes from animal, human and vegetable sources for the improvement of productivity of crops is as old as the practice of agriculture.

Plant nutrients in complex organic forms are present in the manure which is the organic matter in the plant and animal wastes. The synthetic chemicals that contain plant nutrients are called fertilizers.

Manures have low nutrient content per unit quantity and have a longer residual effects. They can work by improving soil's physical properties compared to fertilizer with high nutrient content.  

Therefore, organic matter is added to basic soil to neutralize its base which improves its quality.
