What is humus and why is KELP FIBER a good source of humus?
Humus is the organic part of the soil that is formed from the partial decomposition of vegetable matter in the soil. Humus greatly affects the workability (tilth) and structure of soil because it is essentially fibrous in nature and thereby prevents hardening of packed soil particles into a mass. It makes the soil more friable (loose) by physically separating the packed soil particles and by chemically causing them to aggregate together (by combination with existing soil colloids which are small insoluble particles that remain suspended in a fluid medium to make a gelatinous substance.) This complex restructuring of the soil increases the amount of pore space in the soil and also produces a more hydrophilic (water attracting) surface. This in turn, improves the water-holding capacity of the soil. These beneficial effects are all produced by adding humus to the soil, and KELP FIBER is an excellent source of humus. Humus is formed from those parts of decaying plant material that are most
