Sand soils and silt soils
1. Sand soils
Sand soils are often dry, nutrient deficient and fast-draining. They have little (or no) ability to transport water from deeper layers through capillary transport. Therefore, tillage of sandy soils in the spring should be kept to a minimum in order to retain moisture in the seedbed. The nutrient- and water-holding capacity of sand soils can be improved through adding organic material.
2. Silt soils, 0-10% clay
These soils differ from sand soils by having a greater tendency to form a crust, which is often very hard. If they are over-tilled, they can become compact and this decreases their ability to infiltrate water in wet periods. In dry conditions they can become hard and difficult to till. However, they are generally easy to till and can store considerable amounts of water. They require good reconsolidation, but tillage in wet conditions should be avoided.
