Application Of Differentiated Technologies In The Precision Agriculture System Of Northern Kazakhstan

The most important stage of the transition to precision agriculture is the assessment of spatial heterogeneity of fields and the calculation of doses of differentiated fertilization. Modern means of differentiated application of fertilizers allow you to make different doses of mineral fertilizers in the designated elementary areas. Therefore, when composing soil and agrochemical maps, it is necessary to take into account the characteristics of each field with high accuracy. To do this, in the conditions of production of «AES «Zarechnoye» LLC, scientists conducted agrochemical surveys and compiled digital agrochemical maps. Based on the results of calculating the economic efficiency of differentiated application of mineral fertilizers, it is worth noting an increase in the cost of fertilizer application at different levels of mobile phosphorus availability. However, this event was profitable in all its variants. Thus, the application of mineral fertilizers during sowing provided an increase in profitability relative to the control options from 11.7 to 40.3%. These indicators were achieved not only due to the growth of the crop, but also due to the higher price for high-quality products.Differentiated use of plant protection products – pre-sowing chemical treatment with a John Deere 4730 sprayer equipped with an autopilot system and a WeedSeeker system, reduced the number of overlaps, thereby increasing the accuracy ofthe unit’s movement along the lines and improving its productivity, saving glyphosate up to 7%.
