In course of the research there was determined dependence of composition and carrying out of nutrients by spring wheat (Triticum aestivum) yield on the levels of content of mobile phosphate. The field experiment with fertilizer treatments of spring wheat on the four different levels of sod-podzolic sandy loam soil with mobile phosphates was realized in 2005-2007 in the conditions of the Republic of Belarus. As a result of the realized research it was revealed a significant increase of phosphorous content in grain (in 1.2 – 1.3 times or on 0.14 -0.19%) and straw (3 - 4 times or from 0.06 – 0.09 to 0.26 – 0.27%) at increasing of content of mobile phosphates from 67 to 400 mg of P2O5 on 1 kg of soil. Pre-set values of carrying out of phosphorus and other nutrients (natrium, potassium, calcium and magnesium), which could be taken into account at planning of system at spring wheat fertilizing on the analogous soils with various levels of providing with phosphorous, were presented.
