Describe the important of the factor that makes the soil fertile
Answers
Answer:
Factors Influencing the Fertility of the Soil:
Soil pH - After testing the soil, you determine the existing pH level of the soil. Along with that, you would discover the nutrients that are available that can be used for planting crops.
Organic matter - You can also increase the fertility of the soil by determining the presence of certain organic materials that contain nutrients in them. These can be reused for the next growing cycle.
Moisture content - The amount of moisture that resides in the soil can also influence soil fertility. Actual nutrients can be found in the soil solution and not the solid matrix. Therefore, it's more desirable to use soil with higher moisture content to increase and ensure its fertility.
Clay content - Through the soil's clay content, the cation exchange capacity (CEC) is determined. There are more nutrients present in soil with a higher CEC than its opposite. Low CEC indicates the possibility of easily losing nutrients by leaching.
Bulk density - Soil fertility also depends on its bulk density. As a rule of thumb, the soil to be used should not be compacted. Or else, it can easily obstruct root penetration. If this happens, it's going to be difficult for the roots to reach the nutrients it needs.
