There are four main types of soil: sand, loam, silt, and clay. Each one has a different granule size, and different water retention rates. Granule size is important when referring to gardening because the larger the granule size, the more air can get to the roots. Air is a very important factor in eliminating root-rot.
Sandy soil consists of comparatively large granules, causing it to not hold water very well. However, on the other side of the spectrum, clay soil has minuscule granules, which makes it very hard for it to absorb water in the first place, but once it does, it will hold it for an extremely long time. Loam is considered the "ideal" soil because it balances water retention with granule size providing the optimum medium for bacteria and plants to grow. But clay soil remains the soil type with the finest grain and highest water retention rate.

surface soil
Clay retains the most water.
A plant that grows in soil and holds little water is that is does not need nutrient.
Soil absorbs heat much faster than water, but water does not have air in between like soil so it doesnt lose heat as fast, so water holds heat longer
Clayey soil hold the most water of all, as sand and chalk. Loamy soil holds water but not as much as clayey.

Sand holds the least amount of water
soil that is made up of about equal parts of clay, sand, and silt is called loam. it has a crumbly texture that holds both air and water. loam is best for growing most types of plants.
