| Description
| - Organická hmota a její mikrobiální oxidace na CO2 významně ovlivňují potřebu vápenatých hmot a rovněž potřebné meliorační dávky vápna jako činitele tlumícího pH. V analyzovaných vzorcích písčitohlinité ornice (6.106 kg půdy na hektar) se známým obsahem vody (1,2.106 litru), je půdní voda schopna využít až 220 kg CaCO3 pro fixaci přebytečného CO2 při zcela nulové eluci. Výsledkem tohoto procesu je tvorba 300-400 kg vodorozpustného Ca(HCO3)2. Navíc, iontová výměna a pufrační systém půdy mají další požadavky na vápenaté hmoty. Z toho je jasně patrné, že dávky vápenatých hmot nemohou být počítány pouze s cílem pufrace půdní kyselosti a spotřebou Ca jako živiny rostlinami, jak je to běžné u ostatních živin. (cs)
- 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 impact of 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, the ion 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 consumption of C
