Influence of grazing patterns on the stability of soil aggregates in semi-arid grasslands (Postprint)

日本語

半乾燥草地において、放牧排除（GE）、寒冷季放牧（CG）、自由放牧（FG）の3つの放牧パターンが植物群落構造と土壌団粒安定性に与える長期的な影響を評価した。その結果、GEとCGはFGと比較して土壌有機炭素と土壌水分含有量を有意に高め、団粒安定性を向上させることが明らかとなった。持続可能な放牧管理戦略の重要性を示唆する。

English

This study evaluated the long-term effects of three grazing patterns—grazing exclusion (GE), cold-season grazing (CG), and free grazing (FG)—on plant community structure and soil aggregate stability in semi-arid grasslands. The results showed that GE and CG significantly increased soil organic carbon and soil water content, and improved aggregate stability compared to FG. The findings highlight the importance of sustainable grazing management strategies.

日本のGX文脈において

日本の草地生態系への直接的な適用は限られるが、土壌炭素貯留に関する基礎的な知見は、国内の放牧地管理や農地の炭素隔離策の検討に参考となる可能性がある。

In the global GX context

While the study focuses on semi-arid grasslands not typical of Japan, it provides empirical evidence on how grazing management affects soil carbon stocks, which is globally relevant for developing sustainable land-use practices that contribute to climate mitigation.
