Agroblen fertiliser is recommended for outdoor, soil-based cultivation. Its granules contain macroelements. The granules of the fertiliser are coated during production. The Poly-S coating protects the nutrients from immediate leaching and gives the formulation a shelf life of several months. Once applied to the soil, soil moisture penetrates the coating and dissolves the nutrients inside the granules. The dissolved nutrients are then continuously released into the surrounding soil from where they can be easily taken up by the roots. Fertilizer granules release nutrients continuously throughout their duration of action. The emptied envelope is later decomposed in the soil. The rate of nutrient release is controlled by the thickness of the resin coating. This also protects the roots of the plants from damaging salt accumulation. The rate of nutrient leaching depends on soil temperature: at higher temperatures nutrients are released more quickly, at lower temperatures the process slows down and the duration of action is longer. The effect times given by the manufacturer are based on an average soil temperature of 21 oC. The release of nutrients starts above freezing point and becomes more intense as the soil is released. As the soil warms, more nutrients are released and less as the root zone temperature decreases. This corresponds to the growth rate of the plants. The unique nutrient release method is particularly effective on soils with low nutrient fixing capacity (e.g. sandy soils). For general use, for transplanted and outdoor cultivation. Balanced nitrogen and potassium ratios. Ideal for soils containing organic matter and potassium fixing soils. Composition: 18%N, 8%P, 16%K, 2%MgO. Duration of action: 2-3 months.
