Sod is grown on specialist farms. For 2009, the United States Department of Agriculture reported 1,412 farms had 368,188 acres (149,000.4 ha) of sod in production. [9]It is usually grown locally (within 100 miles of the target market) [10] to minimize both the cost of transport and also the risk of damage to the product.

About 1,000 soil subgroups are defined in the United States. [6] A soil family category is a group of soils within a subgroup and describes the physical and chemical properties which affect the response of soil to agricultural management and engineering applications. The principal characteristics used to differentiate soil families include ...
An equipment operator uses a trackhoe to install soil nails for a highway abutment. With the design complete, construction is the next step. Most soil nail wall construction follows a specific procedure. First, a cut is excavated and temporary bracing is put in place if necessary.
Among the major field crops, oats, wheat, and rye are sown, grasses and legumes are seeded and maize and soybeans are planted. In planting, wider rows (generally 75 cm (30 in) or more) are used, and the intent is to have precise; even spacing between individual seeds in the row, various mechanisms have been devised to count out individual seeds at exact intervals.
Soil compaction is a vital part of the construction process. It is used for support of structural entities such as building foundations, roadways, walkways, and earth retaining structures to name a few. For a given soil type certain properties may deem it more or less desirable to perform adequately for a particular circumstance.
Soil formation, also known as pedogenesis, is the process of soil genesis as regulated by the effects of place, environment, and history. Biogeochemical processes act to both create and destroy order within soils.
The load of approximately 250 kg per m 2 of a sod roof is an advantage because it helps to compress the logs and make the walls more draught-proof. In winter the total load may well increase to 400 or 500 kg per m 2 because of snow. [1] Sod is also a reasonably efficient insulator in a cold climate.
