WebSilt loam refers to soil having a moderate amount of fine sand and only a small amount of clay; over half of the particles are of the size called silt. When dry, a silt loam appears cloddy, but the lumps can be broken readily. When pulverized, it feels soft and floury. When wet, the soil runs together readily and puddles. WebDec 21, 2024 · Loam soil is a balanced mixture of sand, silt and clay, ideal for growing garden plants. Loam’s mineral content, and the way the three sizes of particles work together, combine to make it extremely fertile. The larger sand grains prevent the soil from compacting, so it drains well and helps oxygen reach plant roots. crypto fond ecran
