If the top layer gets eroded, the soil loses its fertility." Top soil is the most important in any type of farming. The first layer is an important one. Some crops have deep roots and in that case, the second layer also becomes important. If the top layer gets eroded, the soil loses its fertility. Representative Image.

Soil erosion and fertility loss affect a disproportionally large area of land where climate extremes decrease yields the most, aridity increases the fastest, and majority of people's livelihoods depend on agriculture . Halting soil degradation is thus a key priority to realize the zero-hunger development goal. Avoiding competition for land
After adding the fertilizer, moisten the mixture with a brief portion of water to make it easier to mix and activate the beneficial microbes in the soil. Then, gently mix the old and new soil with the other ingredients with your hands. Continue mixing until you distribute all the soil ingredients equally. 8. Let It Cure.
This first layer of soil is the key to the Midwest's immense fertility and agricultural strength, but a resource that is slow to rebuild after major losses like farms are currently experiencing.

The goal of good soil management is to meet essential plant needs. Healthy plants need water, nutrients, oxygen, and a physical medium that allows seeds to germinate, shoots to emerge and grow up toward the sunlight, and roots to anchor the plant by growing strong and deep. In a previous article, Introduction to Soils: Soil Quality, we ...
You can even make your own compost bin and start healing your soil today. 2. Leaf Humus – This is really just a different type of compost. Instead of raking up leaves and throwing them away, allow them to compost. They make a very balanced soil amendment that has balanced Ph levels to add to your garden. 3.
