väetistest

Väetistest is a general term in Estonian referring to fertilizers. Fertilizers are substances that are added to soil or plants to supply nutrients essential for growth. These nutrients can be organic, derived from plant or animal matter, or inorganic, typically manufactured from mineral sources.

The primary nutrients plants require are nitrogen (N), phosphorus (P), and potassium (K), often referred to as NPK. Nitrogen is crucial for leaf growth and chlorophyll production, phosphorus is important for root development and flowering, and potassium aids in overall plant health and disease resistance. Fertilizers may contain one or more of these macronutrients, as well as secondary nutrients like calcium, magnesium, and sulfur, and micronutrients such as iron, manganese, and zinc.

Fertilizers can be applied in various forms, including granular, liquid, or powdered. Their application aims to improve soil fertility, enhance crop yields, and promote healthy plant development. However, overuse or improper application of fertilizers can lead to environmental issues such as water pollution through nutrient runoff and soil degradation. Therefore, responsible and balanced use is generally recommended.
