väetist

Väetist, commonly known as fertilizer, is a substance added to soil or plants to supply essential nutrients necessary for growth and development. Fertilizers are used in agriculture, horticulture, and gardening to enhance plant productivity and soil fertility. They can be derived from natural sources or manufactured through chemical processes.

Natural fertilizers include organic materials such as manure, compost, bone meal, and seaweed extracts. These organic options improve soil structure, increase microbial activity, and release nutrients gradually. Chemical fertilizers, on the other hand, are synthetically produced and formulated to provide specific nutrients in precise amounts, often including primary nutrients like nitrogen (N), phosphorus (P), and potassium (K). Examples include ammonium nitrate, superphosphate, and potassium chloride.

Fertilizers play a key role in addressing nutrient deficiencies, which can limit plant growth and crop yields. Proper application of fertilizers improves plant health, boosts fruit and seed production, and supports sustainable agricultural practices when managed appropriately. However, excess or improper use of fertilizers can lead to environmental issues, such as nutrient runoff, water pollution, and greenhouse gas emissions.

The choice and application of fertilizers depend on factors such as crop type, soil conditions, climate, and farming practices. Integrated nutrient management practices aim to optimize fertilizer use while minimizing environmental impacts. Advances in precision agriculture and soil testing have contributed to more efficient and targeted fertilizer application.

Overall, väetist is a vital component in modern crop production systems, balancing the need for increased food security with environmental sustainability.
