The Act also gave directives to conserve the soil in the "high plains"—soil that was being raised into huge dust bowls during the 1930s. This period, known as the Dust Bowl, coupled with the economic hardships of the Great Depression, hit farmers particularly hard. The act attempted to correct earlier government policy that encouraged farmers ...
Houston black soil extends over 1,500,000 acres (6,100 km 2) of the Texas blackland prairies and is the Texas state soil. The series is composed of expansive clays and is considered one of the classic vertisols. [1] Houston black soils are used extensively for grain sorghum, cotton, corn, small grain, and forage grasses.
Soil quality reflects how well a soil performs the functions of maintaining biodiversity and productivity, partitioning water and solute flow, filtering and buffering, nutrient cycling, and providing support for plants and other structures. Soil management has a major impact on soil quality. Soil quality relates to soil functions. Unlike water ...
Texas has the most farms of all United States both in terms of number and size. Agriculture is a major contributor to the economy of Texas and is the primary land use in the state. It is the country's leading producer of livestock. Wine production in Texas is significant, although small by global standards.
Agriculture in Van Zandt County, Texas in 1904. Early Czechoslovakian and German immigrants arrived in the region around 1825 to 1845 and found the rich black soil excellent for farming. By the end of the 19th century 98% of the blackland prairies were cultivated and it was the leading cotton region of the state, also producing sorghum, corn ...
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 ...
Soil structure is essential to soil health and fertility; soil structure decline has a direct effect on soil and surface food chain and biodiversity as a consequence. Continued crop cultivation eventually results in significant changes within the soil, such as its nutrient status, pH balance, organic matter content, and physical characteristics ...
Soil scientists use the capital letters O, A, B, C, and E to identify the master horizons, and lowercase letters for distinctions of these horizons. Most soils have three major horizons—the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but this horizon can also be buried.
