Název v původním jazyce

Soil organic matter quality and microbial activity as affected by ameliorative liming

Popis výsledku v původním jazyce

The global carbon storage in soils is widely discussed today because of climate uncertainty and maintaining sustainable agricultural production. Human intervention for agricultural or energy production poses many changes in soil management, which highly effects soil quality/health. Permanent grasslands fulfil a wide range of ecosystem functions and have high potential for increasing arable land. Optimizing their management is important to maintain resilient and stable ecosystem. Today, grasslands are becoming more and more disturbed by intensive fertilizing and produced biomass is mainly used as a forage source or energy production. This study examined the impact of long-term grasslands liming on total content of soil organic carbon (SOC), humic substances (CHS), and microbial biomass (Cmic). Furthermore, selected soil chemical parameters and available nutrients content were evaluated. Soil samples were collected from a split-plot field experiment of Mendel University in Brno (locality Kameničky). The soil was classified as Dystric Planosol, medium textured, strongly acidic, with high soil organic carbon content. The yearly liming rate was 1.4 t/ha CaO. The linkage between the soil pH, SOC, Cmic, and available nutrients content was evaluated by the multivariate exploratory techniques and regression models. Results showed that long-term liming affects both soil biota and carbon storage.
