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 ...
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 fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. [3] It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.
The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2] Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia ...
There are various factors that affect soil temperature, such as water content, [84] soil color, [85] and relief (slope, orientation, and elevation), [86] and soil cover (shading and insulation), in addition to air temperature. [87] The color of the ground cover and its insulating properties have a strong influence on soil temperature. [88]
Soil is used in agriculture, where it serves as the anchor and primary nutrient base for plants. The types of soil and available moisture determine the species of plants that can be cultivated. Agricultural soil science was the primeval domain of soil knowledge, long time before the advent of pedology in the 19th century.
The Professional Soil Scientists Association of Texas has recommended to the State Legislature that the Houston Black series be designated the State soil. The series was established in 1902. [ 14 ] National Parks in this area are the Lyndon B. Johnson National Historical Park and the San Antonio Missions National Historical Park .
Agricultural soil science is a branch of soil science that deals with the study of edaphic conditions as they relate to the production of food and fiber. In this context, it is also a constituent of the field of agronomy and is thus also described as soil agronomy .
