In turn, sandy soil is simple to work, and loam soil is moderately difficult to work. Of the three components, sand particles are the largest. When more sand is present in the mix, gardeners consider the loam to be sandy loam soil. Doing so will result in something like cement. Soil Profile – Soil Horizon: O horizon, A Horizon, E horizon, B Horizon, C Horizon or Parent rock, R Horizon or Bedrock. Loam soil holds water better than sandy soil types because of the level of clay particles. Soil Intake Rate and Field CapacityIn addition to the preset soils, you can input your own "Custom" variables to describe your soil composition:- Intake Rate (inch/mm per hour)  Relates to the time required to infiltrate a given quantity of water in a specific soil type. Most soils are a combination of these three particles, but the particle type that dominates dictates many of the properties of your soil.The ratio of these sizes determines soil type: clay, loam, clay-loam, silt-loam, and so on.The ideal soil is 40% sand, 40% silt, and 20% clay. There are 12 different textural categories that fit into what is known as the soil texture triangle: clay, sandy clay, silty clay, sandy clay loam, clay loam, silty clay loam, sand, loamy sand, sandy loam, loam, silt loam, and silt. Problems occur if the builder added fill to the substrate that was of a different soil composition. Knowing the kind of soil you have helps you determine its strengths and weaknesses. The lack of sufficient organic material in a loam soil may result in soil that dries out too quickly, according to the World of Soil.

To find the texture of a soil sample, first separate the fine earth, all particles less than 2 mm, from larger particles such as gravel and stones. With sandy soil, it’s similar to loam soil, having a mix of silt, loam, and sand. While sand is coarse-grained and drains most of the water, loam retains some amount of water in this type of soil. Loam and silt are rich nutritionally and easier to work than clay soil, and loam's and silt's particles are not damaged when the soils are worked while wet. The sandy loam category is made up of about 60 percent sand, 30 percent silt particles and 10 percent clay. 2. Aeration. It has good water drainage and allows air to infiltrate the soil like sand, but it also holds moisture well and is fertile like silt and clay. Sandy soil essentially consists of small particles formed by weathering rocks. Sandy soil will not hold water, it drains away, clay holds water, so water logging takes place, loam is perfect for growing, it holds water, but does not water log. Crushed Concrete Rock" for additional details on the differences of the types of Crushed Rock). Sand particles are the largest of the three.
