How could we improve structure of the soil?
Adding compost to a sandy or clay soil significantly improves the soil structure, which in turn makes plants healthier. Compost is the great equalizer; a 2-inch layer of compost incorporated into the top 6 to 8 inches of soil will help clay soil become more porous and sandy soils less porous.
How can we improve soil structure and drainage?
Adding lots of organic matter such as compost, farm manure, or shredded leaves to clayey soil will allow it to drain more easily and hold the right amounts of water and air for better plant growth and increased biological activity.
Can you change soil structure?
While changing a soil's basic texture is very difficult, you can improve its structure–making clay more porous, sand more water retentive–by adding amendments. The best amendment for soil of any texture is organic matter, the decaying remains of plants and animals.
How is soil structure developed?
Physical-chemical processes that build soil structure include: Polyvalent cations like Ca2+, magnesium Mg2+, and aluminum Al3+ bind together clay particles.
