In the second half of the twentieth century, production systems were established based on industrial farming, but biological control systems were almost completely neglected in contrast to chemical methods. Over the course of a few decades, industrial agriculture, together with other economic actors, caused such natural damage and losses that it became obvious that this path could not be continued. That’s when the idea of sustainability was born.
Plant protection can only be carried out with a well-prepared, foolproof sprayer at an optimal time and in good quality. Due to errors during the season, it is often impossible to realize these tasks at the most appropriate time, which can lead to significant damage. By using GPS, we can analyze the information obtained in a location-specific way and intervene based on the results. The term precision farming is used to think not at field level, but in patches of equal quality within the field using satellite navigation. Precision production means production adapted to local conditions and needs within the field, an integral part of which is a large number of reliable measurements and the related precisely regulated intervention. The main reasons for the development and spreading application of this production technology are the desire to increase the economy of production, as well as the need for environmental protection, environmentally sound farming and the need for a crop of controlled quality. With manual steering, inaccurate grip connections inevitably arise, even for a highly capable operator. A person gets tired, and as work progresses, the ability to concentrate decreases. Operators compensate for inaccurate connections with greater overlay, which inadvertently increases the number of overlaps on the field. The resulting additional fuel consumption and input material consumption can result in additional costs of 5-15%. Another mistake resulting from inaccurate connection is the amount of uncultivated areas. This is mainly the case in operations where there is no clear distinction between cultivated and uncultivated land. Such a field with uncultivated patches impairs the homogeneity of the crop stock, and this also means a loss of yield.
One of the biggest problems is weather conditions. We need to look at the number of days or hours that can be worked in one decade, as well as take into account technical failures and plant protection problems. With liquid fertilizer application and spraying, site-specific farming can be carried out by applying application maps prepared in advance. The activities carried out this way can be accurately documented and subsequently evaluated over several years. By spraying, the machine's control system switches the dosing system on and off by itself, even one nozzle at a time, observing field boundaries and planned dose sizes. This will eliminate almost 100% of unmanaged lanes and overlaps, which is of paramount importance from an environmental and economic point of view.
