The main chemical soil properties, winter wheat yield and their variability in framework of field
2000
Torma, S.
The extraordinary high spatial variability of basic chemical soil parameters (pH value, content of available forms of phosphorus and potassium) has a great influence on the unequal reached yield of growing plants. There were reached differences in the winter wheat yield by 26% in the 11 hectares field and contents of phosphorus and potassium has been occurred in three categories of nutrient supply. The soil pH has been occurred even in four categories - from extremely acid to weak acid. The economisation of inputs into the soil is one of the most urgent necessity of present agricultural production. There is possible on the base of finding of basic chemical soil properties spatial variability to apply the lime and mineral fertilizers only where is need and in the case of high nutrient content in soil should be the fertilization skipped to avoid the excessive nutrient uptake. Therewith can be contributed to the ecologisation of inputs into the soil. It has an extraordinary meaning in present conception of environment protection and soil as one part of environment
