The utilization of integrated systems in livestock production has been implemented as a practice aimed at intensifying pasture area while maintaining sustainable soil management to enhance total organic carbon (TOC) storage. However, the dynamics systems, involving inclusion legumes or tree components pastures, are not fully understood. Our research assessed soils from pastures composed grass-legume consortia (GLS), silvopastoral (SSP), and monoculture grass (MP), comparing them native forest (NV) Cerrado biome, different evaluation depths: 0-5 cm, 5-10 10-20 20-30 cm. Using indicators such labile (LC), water-soluble (WSOC), microbial biomass (MBC), (TC), nitrogen (TN), index (CMI), stock, we compare potential each system store contrast vegetation soil. SSP GLS did differ terms stock (p>0.050) showed significant reduction TOC compared (p<0.05). Silvopastoral pasture, carbon, content (p>0.05), show similarity NV any analyzed variables Only achieved CMI greater than 100 all depth ranges evaluated. study demonstrated that association between fractions relationship biological attributes can be used proxy for system's sequester Collectively, studied indicate exhibited recovery integration pasture.

Soil microbial communities are essential components of agroecological ecosystems that influence soil fertility, nutrient turnover, and plant productivity. Metagenomics data increasingly easy to obtain, but studies metagenomics face three key challenges: (1) accounting for physicochemical properties; (2) incorporating untreated controls; (3) sharing data. Accounting properties is crucial better understanding the changes in community composition, mechanisms, abundance. Untreated controls provide a good baseline measure separate treatment effects from random effects. Sharing increases reproducibility enables meta-analyses, which important investigating overall To overcome these challenges, we suggest establishing standard guidelines design experiments studying metagenomics. Addressing challenges will promote composition function, can exploit enhance quality, health, fertility.

As the most widely distributed and largest terrestrial ecosystem in world, grasslands play an important role supporting global livestock production maintaining services. In light of accelerated socio-economic development sustained population growth, grassland ecosystems are increasingly subjected to anthropogenic disturbances. However, there is a paucity research examining impact such disturbances on plant–soil–microorganism interactions systems, particularly from perspectives grazing tourism. Accordingly, this study presents comprehensive analysis impacts disturbance over past two decades, employing dual perspective tourism utilizing econometric existing literature through software as CiteSpace. The results demonstrate following: (1) current focus primarily concentrated fields ecology environmental sciences, topics plant diversity, abundance, well intensity grazing.

Grass intercropping under no-till is an option to increase crop residues on the soil surface and diversity. Urochloa spp. frequently selected for improve land use agricultural production because of its high residue production, slow decomposition, as well vigorous, abundant, deep root system. However, effects maize, especially residues, subsequent crops in rotation have not been established. To address this knowledge gap, a field experiment was carried out over 5 years (from 2014 2018) comprising 2 maize monocropping or 3 (common bean-wheat-common bean-wheat-maize). We evaluated medium-term monocropped intercropped with brizantha fertility development, yields, grain nutrient accumulation common bean, wheat, crops.
