NE Indiana-Fort Wayne and NE China | It might be a calcium concentration but I suspect the soil particles are silt. They are the size ( and density) that move with free water. Sand is too heavy and clay is too light to move down. This physical separation due to density is the essence of the curse pronounced by God in Genesis 8:21. The command to till given to man became more than a "suggestion" when it began to rain on the Earth. |
