SSAU professor spoke at a meeting on the agrochemical support of spring field work

In the center of the agrochemical service “Stavropolsky” under the leadership of the Ministry of Agriculture of the Stavropol Territory, a meeting was held on the issue of agrochemical support for spring field work, early spring feeding of winter crops and the specifics of its implementation in 2023. The scientific expert of the meeting was the head of the Department of Soil Science named after professor V.I. Tyulpanov, Doctor of Agricultural Sciences, Professor Valery Tskhovrebov.

The meeting brought together agrarians mainly from the western regions and districts of the Stavropol Territory. SSAU Professor Valery Tskhovrebov acted as the scientific expert of the event and began his speech with the factors that must be taken into account in the early spring top dressing. With the second question, the professor indicated the expediency of conducting an agrochemical survey of soils. The soils of each of the fields of the farm should be analyzed, since the difference in these indicators on the territory of one farm can also be very significant.

— It is necessary to have information about the distribution of nitrate nitrogen along the soil profile. The most active zone for winter wheat is 0-40 cm. From the lower part of the meter zone, nitrogen can be available for winter wheat by the middle or end of the growing season. Its low content in the arable horizon indicates the need for top dressing. The warm winter of 2022-2023 provokes the development of various pathogens in the soil and on plant debris. Excessive and early, before the optimal time, the introduction of nitrogen fertilizers contributes to the development of diseases. Pay special attention to fields with a high nitrogen content. It is necessary to combine biological and chemical methods of control. A prerequisite for making any decision is a survey of the territory, soil-agrochemical and microbiological, - said in his speech the head of the Department of Soil Science named after professor V.I. Tyulpanov, Doctor of Agricultural Sciences, Professor Valery Tskhovrebov.
