For each test, the document describes what is measured, recommends how and when to test, indicates levels at which test results suggest deficiencies or excessive concentrations, and suggests solutions to correct soil imbalances.
The “standard soil analysis package” measures soil acidity (pH) and estimates the plant-available concentrations of the major nutrients, phosphorus (P), potassium (K) and magnesium (Mg), in the soil.
TEXTURE is determined by Feel Method and indicates approximate CEC (Cation Exchange Capacity) range. The higher the CEC, the higher the soil's nutrient and water-holding capacity. The Bouyoucos analysis by Hydrometer, an alternative method, is also available as an option (% Sand - % Silt - % Clay).
Most sandy soils have calcium concentrations below 400 to 500 parts per million (800 to 1,000 lb/acre), while clayey soils usually test above 2,500 ppm. Normally, the higher the calcium level, the greater the soil clay content. Recent limestone applications may result in higher calcium levels.
3 Οκτ 2014 · nutrients and soil properties. The subsoil sample (6-24 inch) is analyzed for mobile nutrients and soil properties such as nitrate-N, su. fate-S, chloride, and salinity. The deep subsoil sample (24-48 inch or deeper) is also . analyses routinely co.
5 Μαΐ 2020 · I can look at a soil test and predict whether it's from an arid or wet climate based on how much chloride is on the test. If there's really low chloride on the paste test, usually that's indicative that there's been a lot of water running through that soil profile and leaching it out.
Calcium is closely related to soil pH. Calcium deficiencies are rare when soil pH is 6.2 to 7.2. The level for calcium will vary with soil type, but optimum ranges are normally in the 65% to75% of cation saturation range. Calcium saturations above 85% may indicate a calcareous soil.
