Soil Conservation with Green Manures - The Garden Forum.
Nobody has perfect dirt, yet soil is the most fundamental resource for rural living.
Fortunately, there are ways to remedy common soil problems on a large scale that are both effective and economical. The key is understanding the basics of what makes soil productive. Two of the most important soil qualities are structure and fertility. All soils are composed of particles of different sizes, and the proportions of these sizes relate to the texture or structure of the soil. Particle sizes are divided into three sizes, with the largest being sand, medium sized particles are silt, and the smallest are clay.
