“…As a result, the soil becomes more susceptible to various forms of degradation, including acidification, wind and water erosion, low water retention, and pedocompaction. Bramble et al (2024), Karabcová et al (2015), and Pospíšilová et al (2011) discussed the opposite effect of fertiliser on SOM, where fertiliser positively increases plant production but reduces species diversity in grassland. Simiraly to us, they demonstrated that SOM accumulation in temperate grasslands is affected by management practices and fertilisation.…”

Soil organic matter (SOM) represents one of the largest and most important reservoirs of organic carbon in terrestrial eco-systems. The quality of SOM (e.g., content of soil organic carbon, humic substances, humic acids, fulvic acids, and HA/FA ratio) is a key factor in determining soil fertility and productivity. The loss of SOM is currently considered a detrimental form of soil degradation. The study aims to evaluate the effect of mineral fertilising (NPK), farmyard manure, cattle slurry, and digestate applications in intensively used permanent grassland. The long-term field experiments were carried out at the locality Jevíčko, region of Boskovice Furrow Malá Haná (the Czech Republic). The effect of amending soil with different organic and mineral fertilisers was studied. Qualitative parameters of SOM, soil reaction, and the content of available nutrients (N, P, K, Ca, Mg) were followed. Results showed that the control (no organic input) and the NPK variants had the lowest SOM quality. Higher SOM quality was after the farmyard manure, Slurry, and Digetsate applications. The highest acidity (indicated by the lowest values of pH/KCl) was determined in the control, NPK, Slurry, and D variants. The most favourable soil reaction and available nutrient content were after the farmyard manure application. Humic substances spectral absorption in the UV-VIS and infrared spectral ranges showed that the highest absorbance and amount of aliphatic hydrophobic components were observed after the application of farmyard manure. The multi-criteria statistical evaluation, including principal component analysis and factor analysis, confirmed that amending soil with farmyard manure and slurry resulted in an increase in humic substances content and improved SOM quality.

“…With regard to the discussed factors of grassland degradation, it should be emphasised that studies conducted by various authors prove that there is a positive relationship between the SOC content in grassland soils and their pH [KARABCOVÁ et al 2015], the state of humidity [KERR, OCHSNER 2020;TIAN et al 2016], and the level of fertilisation [VARGOVÁ et al 2020].…”

The aim of the study was to recognise the accumulation of organic carbon (SOC) in the soils of Polish grasslands (GL) and to consider the possibility of increasing its sequestration in these soils. The Tiurin method (mineral soils) and the mass loss method (soil of organic origin) were used. It was found that: (i) the average SOC content of mineral soils is 2.44% and of organic soils -10.42%; (ii) according to the Polish criteria, approximately 84% of GL mineral soils are classified as classes with high and very high SOC content, and over 15% and 1% -in classes with medium and low SOC content, respectively; more than 99% of organic soils belong to two classes with the highest SOC content and less than 1% to the class with an average content; (iii) according to the European Soil Bureau, the share of GL mineral soils with a high SOC content is slightly over 4%, medium -slightly over 47%, and low and very lowaround 50%; for organic soils they are 67, 29, and 4%, respectively; (iv) the reserves of organic carbon in the 0-30 cm layer on the entire surface of GL soils amount to 412.7 Tg of SOC. There is considerable scope for increasing the SOC stock in meadow-pasture soils.

The aim of the study is to evaluate the content of organic carbon (Corg) in the soils of Polish grasslands (GL). The Tiurin's method (mineral soils) and the mass loss method (soil of organic origin) were used. It was found that: /i/ the average Corg content of mineral soils is 2.44% and of organic soils – 10.42%; /ii/ according to the Polish criteria, about 84% of GL mineral soils are classified as classes with high and very high Corg content, and over 15% and 1% – in classes with medium and low Corg content, respectively; more than 99% of organic soils belong to two classes with the highest Corg content and less than 1% to the class with an average content; /iii/ according to the European Soil Bureau, the share of GL mineral soils with a high Corg content is slightly over 4%, medium – slightly over 47%, and low and very low – around 50%; for organic soils they are 67%, 29%, and 4%, respectively; /iv/ the reserves of organic carbon in the 0–30 cm layer on the entire surface of GL soils amount to 412.7 million tons of Corg. There are opportunities to increase the Corg stock in meadow soils.
