Some of the main functions of humins within the soil are to improve the soil's water holding capacity, to improve soil structure, to maintain soil stability, to function as an cation exchange system, and to generally improve soil fertility. Soil aggregation is improved by increased organic matter content and hence has a role in maintaining soil structure, drainage and aeration; all of which are necessary for good crop yields. Before a foundation is considered ,it is necessary to investigate the properties of the soil. Sand, silt, clay and organic matter help provide tilth, necessary aeration and favorable water intake rates, but they seldom maintain adequate plant food to sustain continuous healthy plant growth. If the moisture content of a soil is optimum for plant growth, plants can readily absorb soil water. soil or dust deposit can provide important clues to nature and provenance It influences a variety of analysis Fully automated, modular sampling systemsScience, and each year hosts an international soil science conference.
