    ORGANIKSAORGANIKSA Black Diamond Humic Acid
    • Functions:Fertilizer
    • Chemical Family:Humic Acids
    • Application Technique:Sprayers
    Black Diamond Humic Acid is specially recommended on chalky soils, poor in organic matter or soils which salinity makes the uptake of nutrients more difficult to plants. Its use improves the physicochemical characteristics of the soil and favors microbial life. Black Diamond Humic Acid As a whole, plants develop better their root system and dispose of more readily accessible nutrients. Generally these products are used on soils diluted in irrigation water. Its use is recommended before sowing or planting and during the first third of half of the culture. Dosage is a according to the soil and crop characteristics and whenever it is the case with the nutrient richness of the formulation. Calcium uptake by the plant is passive and does not require energy input. Calcium mobility in the plant takes places mainly in the xylem, together with water. Therefore calcium uptake is directly related to the plant transpiration rate. Conditions of high humidity, cold and a low transpiration rates may result in calcium deficiency. Salinity buildup might also cause calcium deficiency because it decreases the water uptake by the plant. Since calcium mobility in plants is limited, calcium deficiency will appear in younger leaves (die back or burns) and in fruits (blossom end rot, bitter pit), because they have a very low transpiration rate. Therefore, it is necessary to have a constant supply of calcium for continued growth. Soils with adequate amounts of calcium tend to be more friable and have better water infiltration properties. This is because calcium displaces sodium in the soil, and with adequate leaching irrigations, it can help improve overall soil quality. Soils that have high sodium and low calcium become sodic and do not allow for good water penetration.
