Abstract
Changes in land use from high-nature-value grasslands to arable fields reduce the organic carbon stock in soil, increasing atmospheric carbon concentrations. Maintaining grasslands through traditional agricultural techniques can mitigate climate change by transferring atmospheric carbon to the soil. Benefits of soil organic carbon [...] Read more.
Changes in land use from high-nature-value grasslands to arable fields reduce the organic carbon stock in soil, increasing atmospheric carbon concentrations. Maintaining grasslands through traditional agricultural techniques can mitigate climate change by transferring atmospheric carbon to the soil. Benefits of soil organic carbon sequestration include improved soil properties and enhanced ecosystem services and biodiversity. With Romania’s ratification of the Paris Agreement, it is crucial to review climate-related agricultural policies and incentivize carbon sequestration practices in organic soils. This paper presents a soil carbon study in Transylvania’s Târnava Mare region, Romania, known for its preserved cultural landscapes. Soil samples were taken at a depth of 60 cm to assess organic carbon pools under grassland and arable land management across three soil classes: Cernisoils, Hidrisoils, and Luvisoils. Several statistical tests were applied to evaluate the most significant drivers of soil organic carbon sequestration including land use, soil class, and soil depth. The results indicate that land management has the largest impact, with grasslands storing 45% more carbon than arable land on average. This finding should be integrated into national climate action plans, prioritizing the preservation of grasslands and sustainable agricultural practices to support soil organic carbon sequestration.

This study aimed to evaluate the fertilizing value of rye stillage used in the cultivation of winter triticale cv. ‘Grenado’. The research was performed in 2018 (autumn, before the application of the stillage), 2019, and 2020 (spring and autumn after stillage application) on Luvisoil at the depth levels of 0–20 and 20–40 cm. Each year, the basic soil parameters were analyzed, i.e., pH in 1M KCl, organic carbon (Corg), available phosphorus (P), potassium (K), magnesium (Mg), zinc (Zn), and copper (Cu). Enzymes were also accounted: alkaline phosphatase (AlP), acid phosphatase (AcP), and dehydrogenases (DEH). The use of stillage resulted in a significant increase in the content of P, K, and Mg and the activity of AlP, AcP, and DEH in the soil. It significantly increased the Corg content and did not have a significant effect on pH. The obtained results indicate that the response of the enzymatic activity to the distillery stillage depended on both the sampling season soil and the depth. However, it is necessary to systematically monitor the pH of the soil and at the same time to rationally apply mineral fertilization. Full article
