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.
Soil test kits are available but aren't the best option for a good understanding of what's going on in the soil. "At-home soil test kits can result in inaccurate or inconsistent results," she says.
A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.
Soil acidification is the buildup of hydrogen cations, which reduces the soil pH. Chemically, this happens when a proton donor gets added to the soil. The donor can be an acid , such as nitric acid , sulfuric acid , or carbonic acid .
Sulfur has long been known to contribute to damage. This is true for many materials such as metal corrosion, or concrete degradation. In King Lear, Shakespeare says: [5] There’s hell, there’s darkness, there is the sulphurous pit, Burning, scalding, stench, consumption; fie, fie, fie!
With 0.023 g flowers of sulfur per kg of soil, vegetation growth increased by 10 to 40%. [10] Flowers of Sulfur (FoS) Tests have also been used to test porosity of metallic finishes over silver, copper, and copper alloy substrates. The original FoS test method was standardized by ASTM through ASTM-B809 which was established in 1990.
Inland acid sulfate soil systems across Australia: CRC LEME Open File Report 249 [24] [39] (Fitzpatrick and Shand, 2008) provides a comprehensive introduction to the subject as well as more detailed discussion on select aspects such as the mineralogy of and toxic gas emissions from acid sulfate soils. The report also contains a range of ...
