Yhdistelmälannoitteet, known in English as compound fertilizers or mixed fertilizers, are agricultural products containing two or more essential plant nutrients in a single granule or formulation. These nutrients are typically nitrogen (N), phosphorus (P), and potassium (K), often referred to as NPK. However, compound fertilizers can also include 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 key advantage of compound fertilizers is their convenience and efficiency. By combining multiple nutrients in a balanced ratio, they allow farmers to apply all necessary elements for plant growth in a single application. This reduces labor, fuel, and machinery costs associated with separate fertilizer applications. The nutrients in compound fertilizers are often processed and granulated together, ensuring a uniform distribution of each nutrient in every granule. This homogeneity helps prevent segregation of nutrients during handling and application, leading to more consistent crop nutrition.

The specific nutrient ratios in compound fertilizers are tailored to the needs of different crops, soil types, and growth stages. For example, a fertilizer high in phosphorus might be used for root development, while one with a higher nitrogen content is beneficial for leafy growth. Farmers and agronomists select compound fertilizers based on soil test results and crop requirements to optimize nutrient uptake and minimize waste, thereby improving crop yields and quality while reducing environmental impact. The production process involves various methods, including chemical granulation, blending, and pressing, to create the desired nutrient composition and physical properties.
