Väetusomadused

Väetusomadused refers to the properties of a substance that contribute to its ability to act as a fertilizer. Fertilizers are substances that provide essential nutrients to plants, promoting their growth and development. These nutrients are typically in the form of chemical elements that plants need in large or small quantities.

The main macronutrients provided by fertilizers are nitrogen (N), phosphorus (P), and potassium (K), often referred to by their chemical symbols. Nitrogen is crucial for leaf growth and the formation of chlorophyll, the pigment essential for photosynthesis. Phosphorus plays a vital role in root development, flowering, and fruiting. Potassium is important for overall plant health, disease resistance, and water regulation.

Micronutrients, such as iron, manganese, zinc, copper, boron, and molybdenum, are also essential but are required in smaller amounts. Fertilizers can be categorized based on the nutrients they supply. For example, nitrogenous fertilizers primarily provide nitrogen, while phosphate fertilizers supply phosphorus. Compound fertilizers contain a combination of two or more primary nutrients.

The väetusomadused of a substance are determined by its chemical composition, solubility, and the form in which the nutrients are present. For instance, the rate at which a nutrient is released into the soil and becomes available for plant uptake is a key aspect of its fertilizing properties. Organic fertilizers, such as compost and manure, also possess väetusomadused, releasing nutrients more slowly as they decompose. The effectiveness of a fertilizer is also influenced by soil type, pH, and environmental conditions.
