This practice describes the use of available satellite images to monitor actual crop status and act quickly on it. This helps to use fertiliser inputs more efficiently and reduce costs. Variable rate fertiliser prescription maps are traditionally based on soil samples of a given area. The aim of this new approach is to optimize fertiliser use, reduce costs and at the same time increase the efficiency of fertilization using crop information acquired from satellite images. Satellite images make it possible to retrieve information on the state of agricultural areas in a global level. These images can be used so that farmers, researchers and agronomists can monitor plant growth, assess field conditions and identify potential problems that affect the quantity and quality of crops. With the latest development of satellite technology, images have become increasingly accurate and more accessible, making it easier to use them in agricultural practice. A significant advantage is the speed with which information on the situation of crops in the field can be obtained so that the farmer can react immediately with the application of appropriate fertilisers at the right location.
