Fertilizer based on leaf granules+horse manure+sheep wool

Abstract

Fertilizer granules, characterized by the components leaves, horse manure and sheep wool in a certain ratio

Description

The invention relates to fertilizer granules from the natural starting materials leaves, horse must and sheep wool. The granulate serves as an organic fertilizer for improving soil fertility and for supplying plants with nutrients.The granulate is made from such a specific mixture of leaves, dried horse must and sheep wool, in order to achieve a balanced carbon-nitrogen ratio (C:N ratio) of 25:1 to 35:1 and at the same time not to exceed the limits of the fertilizer regulation (DüMV).Leaf granules typically have the following properties:• Carbon (C): High proportion of cellulose and lignin (C:N ratio of 40:1 to 60:1).• Nitrogen (N): 0.4-0.6%• Phosphorus (P 2 O 5): 0,1-0,3 %• Potassium (K 2 O): 0.4-0.6%• Organic substance: 70-80%Dried horse must typically have the following properties:• Nitrogen (N): 1.3-1.7%• Phosphorus (P 2 O 5): 0,5-0,7 %• Potassium (K 2 O): 1.0-1.4%• Organic substance: 70-80%• C:N ratio: 20:1 to 30:1• pH 6.5-8 (slightly alkaline)Sheep wool typically has the following properties:• Nitrogen (N): 9-13%• Phosphorus (P 2 O 5): 0,1-0,3 %• Potassium (K 2 O): 0.2-0.4%• Organic substance: > 90 %• C:N ratio: 4:1 to 8:1• High water-holding capacityThe granulate of the specific mixture of leaf granulate, dried horse must and sheep wool has the following nutrient composition:• Nitrogen (N): 1.43%• Phosphorus (P 2 O 5): 0,32 %• Potassium (K 2 O): 0.698%• Organic substance: 75-85%• C:N ratio: 25:1 to 35:1The granules are dried to reduce the moisture to a level suitable for granulation (e.g. 10-15%). Optionally, additives such as rock flour, algal lime or micronutrients can be added in order to optimize the nutrient content.The finished fertilizer granules have the following material composition:• Nitrogen (N): <1.43%• Phosphorus (P 2 O 5): < 0,32 %• Potassium (K 2 O): <0.698%• Organic substance: 75-85%• Micronutrients: traces of magnesium (Mg), calcium (Ca), iron (Fe), zinc (Zn) and other trace elements.The granulate is suitable for use in agriculture, horticultural and landscape care. It improves soil structure, increases humus content and provides plants with nutrients over the long term. The addition of sheep wool also improves the water-retaining capacity of the soil.The granulate meets the requirements of the fertilizer regulation (DüMV). In particular, the pollutant limits for heavy metals (e.g. cadmium, lead, nickel, mercury) are complied with. The granulate is regularly tested analytically in order to demonstrate compliance with the legal requirements.
