Why is sand not considered soil?

Sand is not considered soil because soil is made up of sand, silt, and clay particles along with organic matter and various microorganisms. Sand is primarily composed of large particles of rock, lacking the organic material and soil structure that defines true soil. Furthermore, sand is less able to support plant growth compared to soil.

Does dolomite reduce soil acidity?

Yes, dolomite reduces soil acidity. Its addition to the soil raises the soil pH, which is measured on a 1-14 scale. Midpoint is considered a neutral pH. Below about 6.5-7 is considered acidic. Above it is considered alkaline.


How much fertility in soil has to be lost before the soil can be considered infertile?

There is no specific threshold for when soil is considered infertile, as fertility is influenced by a variety of factors including nutrient content, pH levels, and organic matter. Generally, if a soil's fertility has declined significantly and cannot support plant growth without added inputs such as fertilizers, it may be considered infertile. Soil tests and monitoring plant growth can help determine fertility levels.
