Composition soil testing
Is there a test to get a percentage of organic matter in a soil
sample? Anyone know how is this typically done in a lab? I was wondering if the sample is weighed, burned off, and re-weighed to calculate a percentage? I guess compost made from leaves, twigs, peat moss, grass would be close to 100% "organic matter." Sand, stones, clay, perlite, vermiculite, water, nitrogen salts would be "inorganic matter?" What I am hearing is that good soil must have greater than 5% organic matter. |
