    Soil testing system in the Czech Republic - upgrade for agricultural practice

  • Original language description

    The systematic soil testing system in the Czech Republic has long-term duration - was established 1961. Presently more than 500 thousand hectares agricultural soils are tested every year for determination wide scale soil properties, including content of available nutrients. Since 1999 extraction method Mehlich 3 is used for determination basic macronutrients (content of available phosphorus, potassium, calcium, magnesium). Uniformity, suitability and relatively cheap process of this analytical procedure are crucial point for wide expansion in practice. The Mehlich 3 extractant can be used for a multiple-element extraction from soils with a relatively wide pH range (with some limitations for carbonate soils) and it has a potential for a simultaneous determination of plant avail¬able nutrients, micronutrients (e.g. Mehlich, 1984) as well as available fractions of some risk elements (e.g. Čižmárová et al, 2016; Zbíral, 2016). Suitable and reliable criteria for fertilizer recommendation for Mehlich 3 extractant in the Czech soil testing scheme were established only for K, Mg, Ca and P. Based on comparison different analytical method (i.e. Mehlich 3 versus DTPA and hot water) and through simple calculation of relationship between these extractants, new criteria for available copper, zinc, iron, manganese and boron were suggested (Zbíral, 2016). The goal of next works was to verify this first proposal of criteria for micronutrients valuation in the soil to improve for individual soils according to results from pot and field experiments.
