The farmer practices crop rotation, where different crops are planted in succession to replenish nutrients in the soil. This helps prevent soil exhaustion and maintains soil fertility. Additionally, the farmer may add organic matter such as compost or manure to improve soil structure and nutrient content.
draining of nutrients 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.
A cover crop use can replace nutrients in the soil by adding organic matter and nitrogen through decomposition. No-till farming helps to improve soil structure and reduce erosion, allowing nutrients to remain in the soil. Terracing and contour plowing focus more on preventing soil erosion rather than directly replacing nutrients in the soil.
what following do you mean you didnt list them
This largely depends on the soil and how the soil is tilled by each individual gardener or farmer. Typically the Top Soil will have the most nutrients available.
There are nutrients in the manure that plants need. The manure is a natural fertilizer.
They get their nutrients from the roots they grow underground. The roots "soak" up the nutrients and water the plant needs.
All plants will deplete the soil by the fact that they take nutrients from it. The art of the good gardener is to replace the nutrients taken.
No, you do not have to replace garden soil every year. It is recommended to amend and improve the soil with compost and other nutrients regularly, but complete replacement is not necessary annually.
if the farmer do not replenish the soil the crops will damage.
Because it contains plenty of nutrients and minerals that plants need to grow that can be incorporated into the soil.
