Grazing has been shown to impact the soil environment and microbial necromass carbon (MNC), which in turn regulates organic (SOC). However, sequestration potential of fungi bacteria under different stocking rates remains unclear, limiting our understanding grazing management. In 2004, we established experiments desert steppe northern China with four rates. Our findings indicate that MNC decreased moderate heavy grazing, while light did not significantly differ from no grazing. Notably, reduction fungal carbon, rather than bacterial was primarily responsible for contribution SOC. This difference is attributed varying effects sheep on community characteristics, including richness, diversity, composition. Thus, accurately predict dynamics grassland ecosystems, it essential consider ecological impacts communities may vary management practices.

The objective of this study was to analyze soil organic carbon (SOC) and environmental footprints—water carbon—in an area livestock intervention located in the high tropics. work conducted La Nevera, Colombia, 03°33′460″ N–76°06’278″ W 03°31′405″ N–76°01’804″ W, between 2700 3300 AMSL. Estimates (t SOC/ha), footprint (kg CO2eq/kg product generated), water (m3 per kg primary product) were made. results obtained were: for forest cover 237,491.91 tons (33 t SOC/ha) average bulk density 0.46 (g/cm3) at a depth 10 cm. For vegetation cover, amount SOC 52,281.22 (25 SOC/ha). greenhouse gases emitted by activity estimated 2,119,416.29 CO2eq/year, with emission intensity milk production 2.77 34.71 meat. cattle farming consumed 1,909,430.83 m3 year, 2.5 m3/kg produced 35 Given negative impact on resources low biological efficiency, it is necessary intervene systems.

The high resource intensity of industrial beef in high-income economies has prompted growing interest alternative, potentially lower environmental impact production pathways. Of those, grass feeding is promoted by some as one such but rigorous quantification this claim required. Motivated to bridge knowledge gap, we integrate empirical evidence with a model based on authoritative equations governing cattle performance quantify the greenhouse gas emissions producing grass-fed beef. Because geographical specificity and dependence agricultural are key, widely varied herds, from extensive operations semiarid, marginal rangelands partially industrial, intensive ones lusher, more accommodating settings. We find that per kg protein even most efficient 10 25% higher than those US 3- over 40-fold wide range plant animal alternatives.

These differences prove robust across broad set combinations operation types, management practices, ration qualities. Consequently, maximal credit for putative enhancement, no less carbon beef, severalfold

Land-use intensity drives productivity and ecosystem functions in grassland. The effects of long-term land-use intensification on plant functional community composition its direct indirect linkages to processes nutrient cycling are largely unknown. We manipulated mowing frequency nitrogen inputs an experiment temperate grassland over ten years. assessed changes species calculated diversity (FDis) weighted mean (CWM) traits specific leaf area (SLA), dry matter content (LDMC) root the community, using species-specific trait values derived from databases. above- belowground decomposition soil respiration. Plant strongly decreased with increasing intensity. CWM SLA decreased, while LDMC increased intensification, which could be linked proportion graminoid species. Belowground were unaffected by Land use affected aboveground litter directly indirectly via composition. Mowing frequency, not a index combining fertilization, explained most variation decomposition. Our results show that only reduces diversity, but these also affect dynamics.
