How do you balance soil fertility?
7 Creative Ways to Balance Excess Soil Nutrients
- Leaching. Leaching is the removal or loss of soluble nutrients through the application of water, either naturally from rain or intentionally through irrigation.
- Cover Crops. Cover crops are nifty things.
- Crop Selection.
- Rotational Grazing.
- Mulch.
- 15-15-15.
- Balance with Compost.
How can I make my soil more fertile?
Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose …
Which type of soil is most fertile?

What is a good soil moisture?

What is soil moisture affected by?
Soil moisture is the water stored in the soil and is affected by precipitation, temperature, soil characteristics, and more. These same factors help determine the type of biome present, and the suitability of land for growing crops.

How is soil fertility related to human activities?
Soil fertility. In lands used for agriculture and other human activities, maintenance of soil fertility typically requires the use of soil conservation practices. This is because soil erosion and other forms of soil degradation generally result in a decline in quality with respect to one or more of the aspects indicated above.
