Mapping of soil conditions in precision agriculture

Original language description

The present paper verifies the efficiency of the method for electrical conductivity (EC) measurement for the assessment of spatial variability of soil properties in precision agriculture. The verification was carried out in a 53ha experimental field situated in South Moravia, Czech Republic. EC was measured using the EM38 (Geonics Ltd, Canada) in 2004 and 2005. At the same time, topsoil samples were taken for agrochemical analyses of P, K, Mg, Ca, humus content and pH value, and for soil texture analysis. A strong correlation between years of EC measurements (r2 = 0.936) was found, which confirms the stability of EC measurement from a shorttime point of view. Strong relationships between EC and clay content (r2 = 0.548) as well as sand content (r2 = -0.406) confirm the influence of soil texture on EC. Furthermore, almost all examined agrochemical characteristics (P, K, Mg content and pH value) and humus content show relatively balanced, moderately strong correlations with EC. It indica
