Sõnnikust

Sõnnikust, commonly known as manure, is a material composed of animal feces, urine, bedding, and feed residues. It is a valuable organic fertilizer that has been used for centuries to improve soil fertility and crop yields. The composition of sõnnikust varies depending on the type of animal, its diet, and the bedding material used.

Nutrient-wise, sõnnikust is rich in essential plant nutrients such as nitrogen, phosphorus, and potassium, as well as micronutrients. When applied to the soil, these nutrients are gradually released, providing a sustained source of nourishment for plants. Beyond its nutrient content, sõnnikust also enhances soil structure by increasing organic matter. This improves water retention, aeration, and drainage, creating a more favorable environment for root growth and microbial activity.

The application of sõnnikust can be done in various ways, including spreading it on fields before planting, incorporating it into the soil, or using it as a top-dressing. Composting sõnnikust before application is often recommended to reduce weed seeds, pathogens, and odor, and to stabilize the nutrient content. Improperly managed sõnnikust can lead to environmental concerns such as water pollution through nutrient runoff and greenhouse gas emissions. Therefore, sustainable handling and application practices are crucial.
