By avoiding bush burning,erosion and other activities harmful to the soil
You can use a Soil Test kit (Rapitest Soil Test Kit) to find the pH and levels of nitrogen, potassium and phosphorus.
plant long rooted plants(this will help hold down the soil) and keep it damp
There are two ways plants put nitrogen into the soil one is decomposition where a plant dies then decomposes putting the nitrogen back into the soil that it once took out. The other is from the air, Legumes are plants that take nitrogen from the air with their leaves and release it into the soil with its roots.
Nitrogen can enter the soil from plants such as legumes which fix nitrogen in their roots. Also dead plants and animals add nitrogen into the soil.
Which of the following enriches the soil

legumes contain high level of nitrogen which are leeched into the soil. this allows the farmer to then plant crops such as corn that use that nitrogen

if not from the atmosphere , they must depend on a process called nitrogen fixation. They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content

Plants like clover, alfalfa, and beans contain nodules in their roots and these nodules are full of nitrogen fixing bacteria. Plants that contain root nodules are called legumes. Fields are often planted with clover to increase the nitrogen content of the soil. Once the plants have grown they are ploughed back into the soil. As they decay, the nutrients they contain are released into the soil. One advantaged of using legumes is that they are a cheaper source of nitrogen for the soil than artificial fertilisers.There are two main reasons for a farmer to plant mustard: 1) to grow a crop of mustard seed for the production of mustard, a condiment common in the US and Europe; 2) to have a "cover crop" to plow down for organic matter and nutrient content, to enrich the soil. Unlike legumes, mustard's only nitrogen content is that which it was able to draw from the soil.

Farmers turn their soil to replenish valuable nutrients such as nitrogen and oxygen to the soil. If a farmer was to continually use the soil over and over again the nutrient level would be depleted and be deamed useless. Soil need nutrients to survive and allow other plants to grow.
