Väetamisviisi

Väetamisviis refers to the method by which fertilizers are applied to crops or soil. The goal of proper väetamisviis is to ensure that nutrients are available to plants when they need them, in the correct amounts, and in a form that can be easily absorbed. Different väetamisviisid are chosen based on the type of fertilizer, the crop being grown, the soil conditions, and the stage of plant growth.

One common väetamisviis is broadcast application, where fertilizer is spread evenly over the entire surface of the soil. This can be done manually or with machinery. Another method is band application, where fertilizer is placed in narrow bands near the seed or plant roots. This is often more efficient as it concentrates nutrients where the plants can access them.

Foliar application is a väetamisviis where liquid fertilizer is sprayed directly onto the leaves of plants. This allows for rapid nutrient uptake, especially for micronutrients. Subsurface application involves placing fertilizer below the soil surface, which can reduce nutrient losses through volatilization or runoff. Side-dressing is a type of band application performed after the crop has emerged, typically applied to the side of the rows. The choice of väetamisviis significantly impacts fertilizer efficiency and can influence environmental outcomes by minimizing nutrient losses.
