In Latvia, there are almost no data on the influence of soil agrochemical parameters (phosphorus and potassium content, pH KCL) on development and yield of winter wheat using precision agriculture methods. Investigations were carried out in Research and Study farm "Vecauce" in 2005-2007. The aim of this study was to clarify the effect of soil agrochemical properties on development and yield of winter wheat in production conditions. Soil reaction and phosphorus content were showed significant effect on the winter wheat yield in 2006, when the yield level was 7.50-9.20 t haE-1. Coefficient of tillering and fresh weight of winter wheat plants in both trial years was significantly higher when soil reaction and phosphorus content were above the medium range. Area of flag leaf had significant effect on the winter wheat grain yield in 2006 with the yield level from 7.02-9.02 t haE-1 and in 2007 with the yield level from 3.53-7.05 t haE-1.
