Available Water Capacity 1.5-2.1 inches/foot: Percent Available: Currently available soil moisture as a percent of available water capacity. Clay soil easily compacts, as we have said. If it has more clay than a good loam should have, it would be a clay loam soil. Loam in subsoil receives varied minerals and amounts of clay by leaching (percolation) from the topsoil Soil type, production history, soil testing, and soil amendments may influence potential microbial risks. Soil is formed by different particels such as gravel, rock, sand, silt, clay, loam and humus. If you set the ball aside and let it dry, it will become rock-hard and difficult to break.
