Relationship between soil organic matter lability and liming requirement in acid sandy-loam cambisols

Popis výsledku v původním jazyce

It is evident that the presence of organic matters in soil considerably influences by its microbial oxidation to CO2 the requirement for calcareous compounds as well as the necessary amelioration dose of lime to reduce incurred soil acidity as the impactof balanced buffering CO2-HCO3 system, the more labile the organic matters are. If we take into consideration that the content of soil water per hectare of topsoil is, at the total weight of 6000000 kg, approximately, in analyzed sandy-loam soils 1200000 litre, in the given experiment soil water is just able to use up to 220 kg CaCO3/ha for the fixation of free surplus CO2 to the value of equilibrium CO2, at zero elution! From this process, even 300-400 kg water-soluble Ca(HCO3)2 result. Of course, theion exchange and the buffering system of the soil have further requirements for Ca compounds. Consequently, an unambiguous conclusion is: doses of calcareous compounds cannot be calculated only with the aim of reducing soil acidity and c
