Characteristics of different soil types - from sand to clay

Here is a quick guide to the characteristics of each soil type. 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 ...
