Soil humus is so important in garden and crop production that the necessity of maintaining adequate concentrations of it in productive soils has been recognized and emphasized for many years. Agronomic research has invested humic substances since at least the early 1930’s. Application of humates to almost any type of crop will help to compensate for lost productivity that occurs with soil humus losses, and will help to speed the process of building up necessary reserves of humus in agricultural soils under good management.
Black Earth Humate is weathered sub-bituminous coal (humalite), mined in Alberta, Canada and is similar to weathered lignite (leonardite). Alberta humalite is a highly oxidized naturally occurring organic material that has the lowest ash content at 11%, and the highest humic acid content at 83%, of all humates mined in North America. It is screened to a dust-free consistency and packaged in 25 kg. bags (55 lbs.).
Density: 49 lbs. per cubic ft.
100 lbs. per acre (300 lbs./acre first time for soils with low humus levels). 3-4 times during the growing season, will help strengthen soil structure by binding particles together, enabling increased aeration and root penetration. They will also increase the cation exchange capacity of the soil, and increase the nutrient-and water-holding capacity and directly stimulate plant root and top growth, increasing yields and food quality.
