Variable rate of fertilizers is the most important function of the CropManager program, which allows you to optimize yields and crop quality according to selected scenarios. The benefits of this function are as follows: adjust the amount and type of fertilizers to the needs of plants, soil and climatic conditions, save costs by reducing the use of fertilizers and fuel, reduce the risk of over-fertilization or nutrient deficiency, which affects the health of plants and soil, it is much easier to identify fields ready for harvest, improve the natural environment by reducing greenhouse gas emissions and water pollution. Prepare a preliminary fertilization plan, which will then be sent directly to CropManager. This programme will select the most optimal fertilisation scenario, then simply export it to the machine.
