Soil survey products include the Web Soil Survey, [28] the NCSS Characterization Database [29] and many investigative reports and journal articles. [30] In 2015 NRCS began broad support of soil health, which incorporates less tillage and more cover crops to reduce erosion and improve the diversity of the soil. [31] Information is maintained in ...
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 ...
SSURGO (Soil Survey Geographic database) refers to digital soils data produced and distributed by the Natural Resources Conservation Service (NRCS) - National Cartography and Geospatial Center (NCGC) in the United States. The database has information on soil types and their distribution. The information covers soil characteristics, soil ...
Selection of a hydrologic soil group should be done based on measured infiltration rates, soil survey (such as the NRCS Web Soil Survey), or judgement from a qualified soil science or geotechnical professional. The table below presents curve numbers for antecedent soil moisture condition II (average moisture condition).
What are the most significant threats, in your view, facing our soil and water resources in Mecklenburg County? The decreasing of our impervious surfaces. Development brings roads, parking lots ...
The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil ...
