Soil texture depends on the proportion of particles from each of these groups. For example, a loam has similar proportions of all three classes of particles. Soil structure , or how soil is put together, can be as important as what it is made of. Most soil particles are held together in aggregates of many particles. The size and stability of these aggregates determine the size of pores.
Soil texture is difficult to change, but farming does impact soil structure.
Get this information onto paper, so you can use it as a base map. A base map shows the permanent features of your land. Start your base map by copying or tracing a Soil Survey map or aerial photos. Today, you might just sketch a portion of your farm with a pencil so you can learn what you want to include in your base map. This information is available in the county Soil Survey.
