The article presents the results of research on the state of phosphate regime of soils in the Ternopil region. It was found the weighted average content of mobile phosphorus compounds in the Ternopil region was at the level of 106 mg/kg during the tenth round and up to 112 mg/kg at the time of the eleventh round of their survey. According to the existing classification, this corresponds to an increased content of the studied nutrient. Among the existing administrative districts, the soils of Kremenets and Ternopil administrative districts were characterized by the lowest content of phosphorus available for agricultural crops. During the tenth round of the survey its weighted average amount was 98.5 and 99.8 mg/kg respectively, and during the eleventh round of the survey – 108.3 and 106.9 mg/kg. At the same time, the highest content of this nutrient was noted in the Chortkiv administrative district.
It has been established that there is a clear dynamics of the content of available phosphate in the soils of the studied region – the area of soils with very low, low, medium, high and very high content of this nutrient is decreasing. At the same time, there is an increase in the proportion of soils with an increased amount of mobile phosphorus compounds. The main reason for these processes is the differentiated use of phosphate fertilizers in crop cultivation technologies based on the results of agrochemical soil testing conducted by both public and private laboratories.
Keywords: fertilizers, nutrients, phosphate regime.
