Estimation of narrowness and reliability of connection of increase of winter wheat’s crop yield and of agrochemical properties of soil

The statistical estimation of influence of agrochemical properties of soil, phosphorus doses on variability of an increase of productivity of spring wheat is spent. It is established that features of correlation communications (narrowness, the form) in system «soil – a plant – fertilizer» can be used as a theoretical substantiation for the forecast of efficiency of phosphoric fertilizers.

Keywords: AGROCHEMICAL PROPERTIES of SOIL, CORRELATION, CORRELATION FACTOR, the CORRELATION RELATION, CRITERION of LINEARITY of CORRELATION
