Influence of the Degree of Soil Organic Matter Lability on the Calcium Carbonate Equilibrium of Soil Water

Popis výsledku v původním jazyce

In average samples of three sandy-loamy acid Cambisols from a South Bohemian area labile organic matters were determined by the permangate method modified by the dichromate method, and the rate constant of their biochemical oxidation was determined in hot water extracts of the samples. The need of liming was determined by means of 2 methods. In soil solutions of these samples, all values necessary to evaluate their calcium carbonate equilibriums were determined. The soil samples were enriched with 3% ofdry matter of two organic materials, farmyard manure and meadow clover meal, and were incubated at 25°C for 180 days under wetting above 50% of their retention water capacity, and after this procedure all analyses were repeated. Both methods were foundto increase the need of liming in all three soils: the more labile the organic matter in 3% addition, the higher the need. The meadow clover matter was more labile than the farmyard manure matter. All three methods for the study of soil c
