The amount of water, air and nutrients available for plant growth is affected by the soil physical properties and turf management practices that include watering, mowing, and aerifying and how much the fields are used. Determining the physical properties of your soils will ultimately help you determine how to manage them effectively. Soil texture is based on the relative proportion of sand

Important soil properties — Science Learning Hub

There are several different properties that are really important to soil. The first probably is the physical structure of that soil. It's got to have pores in it that allow water to be able to transport away from the soil surface. Otherwise you just have rain running over the surface, and you'd end up with erosion. It's got to

It is not surprising, then, that soils with more clay have more nutrients than sandy soils. Likewise, deep clayey soils have more nutrients than a clayey surface horizon above sandy subsoil horizons. Eroded soil that once had a clayey surface horizon and a silty or sandy subsoil will also have less nutrient-supplying capacity because of the loss of clay — fine, medium, and coarse. Previous

Characteristics of different soil types from sand to clay

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.

Inorganic amendments (i.e. sand, calcined clay, diatomaceous earth) can be used to improve drainage and aeration along with water and nutrient holding capacity. Long term improvement in soil properties can be achieved by topdressing.

Soils with large percentages of sand are easier to work than soils with large percentages of clay. Clay soils tend to be tighter, making them more difficult to break up or cultivate, whereas sandy soils are looser. A clay soil also takes longer than a sandy soil to dry after a rain. Because of the better drainage, a sandy soil can be worked
