Düngemittelzusatz

Düngemittelzusatz refers to substances added to fertilizers to improve their effectiveness, handling, or release characteristics. These additives are not primary nutrients themselves but serve a functional role in the fertilizer product. Common examples include anti-caking agents, which prevent the fertilizer granules from clumping together, ensuring easier application and uniform distribution. Stabilizers are another category, often used with nitrogen fertilizers to slow down nutrient loss through volatilization or leaching, thereby extending the nutrient availability to plants.

Coating materials, such as polymers or sulfur, are applied to create controlled-release or slow-release fertilizers. These coatings gradually break down or allow nutrients to diffuse out over time, matching plant uptake needs and reducing the frequency of application. Micronutrient chelates are also considered Düngemittelzusatz; they enhance the solubility and availability of essential trace elements like iron, zinc, or manganese in the soil, preventing deficiencies. Other additives can include wetting agents to improve water penetration, pH modifiers to adjust soil acidity or alkalinity, and substances that promote beneficial microbial activity in the soil. The choice and inclusion of Düngemittelzusatz depend on the type of fertilizer, the intended crop, soil conditions, and application methods. Their use aims to optimize nutrient delivery, minimize environmental losses, and enhance overall agricultural productivity.
