The effect of permanent grassland fertilization on the state of soil organic matter and nutrients in Haplic Luvisol

Original language description

Soil and Soil organic matter (SOM) represents one of the largest and most important reservoirs of organic carbon (SOC) in the terrestrial ecosystems. The quality of SOM (e.g. content of SOC and fractional composition of humic substances /HS/: humic acids /HA/, fulvic acids /FA/, HA/FA ratio) is the key factor of soil fertility and productivity. The loss of SOM is currently considered to be clearly a negative form of soil degradation, which disturbs the ecological stability and causes other environmental problems. The aim of the study was to evaluate the effect of long-term application of mineral (NPK), livestock (manure /FYM/, slurry /CS/) and organic (digestate) fertilizers on the state of soil organic matter (SOC content, HS content, fractional composition of humic substances /HA, FA/, degree of humification /DH/, etc.), soil reaction and content of available nutrients in the permanent grassland (PG). The type of studied PG is the oat-type grassland (Arrhenatheretum), with intensive 4-cutting management. The soil type is classified as Haplic Luvisol (region of Boskovice Furrow /Malá Haná/, the Czech Republic). The results showed that the lowest carbon content (SOC) was determined in the variant of control, the highest in the FYM, and lower in the CS, NPK, and Digestate variants. The highest content of HS, HA was determined in the FYM, the lowest in the control variant. The lowest HA/FA ratio was found in the control and digestate variant (0.80-0.87), higher in the NPK and CS (0.91-0.93), and the highest in the FYM (1.13). The lowest values of soil reaction (pH/KCl) were found in the NPK and control variants, the highest pH was determined in the FYM, slightly lower in the CS and digestate variants. The content of available nutrients (P, K, Ca, Mg) was the lowest in the control and NPK variants, higher contents were recorded in the CS and digestate variants, and the highest contents were determined in the FYM. The results of the multicriteria evaluation (principal component analysis, factor analysis) confirm that fertilization with manure (manure /FYM/, slurry /CS/) clearly leads to an increase in soil quality and health (higher soil fertility compared to NPK and digestate fertilization) in the current conditions of the global climate change (GCC).
