Täsmälannoituksen

Täsmälannoitus, often translated as precision fertilization or site-specific fertilization, refers to the practice of applying fertilizers to agricultural fields in a way that matches the specific nutrient needs of the crop and the varying conditions of the soil. This approach moves away from uniform application across an entire field, acknowledging that nutrient levels, soil type, and crop requirements can differ significantly even within small areas. The primary goal of täsmälannoitus is to optimize nutrient use efficiency, reduce environmental impact, and improve crop yield and quality.

The implementation of täsmälannoitus typically involves a combination of technologies and methodologies. Soil sampling and analysis are crucial first steps, providing data on existing nutrient levels and soil properties. Geographical Information Systems (GIS) and GPS technology are then used to create management zones within a field. Variable Rate Technology (VRT) on fertilizer spreaders allows for precise adjustments to the application rate based on the predetermined zones and real-time data. Remote sensing technologies, such as satellite imagery and drone surveys, can also provide valuable information on crop health and nutrient status, further informing the application strategy. By applying nutrients only where and when they are needed, täsmälannoitus aims to minimize nutrient losses to the environment through leaching or runoff, thereby contributing to more sustainable agricultural practices.
