Düngezusammensetzung

Düngezusammensetzung refers to the analysis of the nutrient content of fertilizers. This analysis is crucial for determining the efficacy and appropriate application of fertilizers in agriculture and horticulture. Fertilizers are typically composed of macronutrients, primarily nitrogen (N), phosphorus (P), and potassium (K), often referred to as NPK. They also contain secondary nutrients like calcium (Ca), magnesium (Mg), and sulfur (S), as well as micronutrients such as iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), and molybdenum (Mo).

The specific proportions of these nutrients in a fertilizer are indicated on its packaging, often as percentages or in specific units like grams per kilogram. For example, a fertilizer labeled 10-10-10 would contain 10% nitrogen, 10% phosphorus (expressed as P2O5), and 10% potassium (expressed as K2O). The exact form in which each nutrient is present is also part of the detailed düngzusammensetzung, as different chemical compounds can affect nutrient availability and plant uptake.

Understanding the düngzusammensetzung allows farmers and gardeners to select the most suitable fertilizer for specific soil types, crop needs, and growth stages. This precision in fertilization optimizes plant growth, improves crop yield, and minimizes the risk of nutrient imbalances or environmental pollution from excessive nutrient runoff. Soil testing is often performed in conjunction with analyzing fertilizer composition to ensure a balanced nutrient supply for optimal plant health.
