Physico-chemical assessment of the soil in the technology of growing winter triticale

In the experiment, it was found that the productivity indicators of the aboveground mass of winter triticale of the Tribune variety and the content of nitrogen, phosphorus and potassium in their plant tissues are generally consistent with water-physical, physico-chemical parameters and with soil bonification data. It was found that there were no differences in the mass of green leaves and the dry mass of the aboveground part of triticale on chernozem typical of agrocenosis and virgin soil. Of the forest soils, the smallest mass of triticale leaves was obtained on gray forest and turf alluvial, and the largest on sod–podzolic light loamy soil. Plants with massive leaves were also obtained on alluvial meadow soil of the same light loamy granulometric composition. The water content of triticale leaves, as a rule, does not depend on soil fertility. Only on the chernozem-meadow soil of the trunk strips of the apple orchard, in contrast to the row-to-row soil, the hydration of the leaves turned out to be significantly higher. This can be explained by a less acidic reaction, greater hygroscopicity and nitrogen content in the soil of the trunk strip. In summary, winter triticale plants are recommended to be used as a test crop when assessing the degree of soil cultivation.
