tarkkuuslannoituksen

Tarkkuuslannoitus, also known as precision fertilization, is an agricultural practice that involves applying fertilizers to fields in a highly targeted and precise manner. Instead of broadcasting fertilizer uniformly across an entire field, tarkkuuslannoitus utilizes data and technology to determine the specific nutrient needs of different areas within a field. This approach aims to optimize nutrient use efficiency, reduce environmental impact, and improve crop yields.

The core principle of tarkkuuslannoitus is to deliver the right amount of fertilizer to the right place at the right time. This is often achieved through the use of technologies such as GPS (Global Positioning System), soil sensors, yield maps, and variable rate application (VRA) equipment. Soil samples are taken from various zones within a field to analyze nutrient levels. Yield monitors on harvesters can create maps that show areas of high and low productivity, indicating potential nutrient deficiencies or other limiting factors. This data is then used to create management zones, each with its own specific fertilizer recommendation.

The VRA fertilizer spreaders or applicators can then adjust the amount of fertilizer applied in real-time as they move across the field, based on the predetermined management zones. This ensures that nutrients are applied only where and in the quantities they are needed. Benefits of tarkkuuslannoitus include reduced fertilizer costs due to less waste, minimized nutrient runoff into waterways, improved soil health, and potentially higher and more consistent crop yields. It represents a shift towards more sustainable and data-driven farming practices.
