Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) [ 1] and claimed to be successfully in use on over a million acres (4,000 km 2) of farmland worldwide. The traditional method, as used by ...
A soil test can determine fertility, or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive fertility and inhibitions from the presence of non-essential trace minerals. The test is used to mimic the function of roots to assimilate minerals. The expected rate of growth is modeled ...
Percolation test. A percolation test (colloquially called a perc test) is a test to determine the water absorption rate of soil (that is, its capacity for percolation) in preparation for the building of a septic drain field (leach field) or infiltration basin. [1] The results of a percolation test are required to design a septic system properly.
Soil testing labs are typically less busy in the fall compared to the spring, allowing you to receive results back from the lab more quickly. Soil testing should be done once every three years.
Sanborn Field is an agricultural experiment field, located on the University of Missouri campus in Columbia, Missouri. Established in 1888, it was the first facility in the United States intended to measure erosion and run-off for differing crops and agricultural practices. Work at Sanborn Field was influential in the establishment of soil ...
Proctor compaction test. The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density. The test is named in honor of Ralph Roscoe Proctor [de], who in 1933 showed that the dry density of a soil for a given ...
Symbol used in drawings. Simplified version of a cone penetrometer. The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft ...
The soil tests we offer test both the main macro and micronutrients. These nutrients include phosphorus, exchangeable potassium, calcium, magnesium and more. The tests also include soil pH ...
