Few studies have shown the importance of different pasture management practices on C storage and the reduction of CO2-C emissions in tropical conditions. The objective of the present study was to determine short-term changes in C pools and C balance from different pasture management practices established in the Atlantic Rainforest. A field study was carried out in Alegre, ES, Brazil from September 2013 to August 2014 to investigate the first-year effect of pasture management practices on a Udult clayey soil. The different pasture management practices studied included the following: control (CON), chiseled (CHI), fertilized (FER), burned (BUR), integrated with crop-livestock (iCL) systems, and plowed and harrowed (PH). Monthly disturbed and undisturbed soil samples were taken at two different layers (0.00-0.05 and 0.05-0.20 m) for chemical, physical, and organic matter characterization. C inputs monitored in aboveground pools included plant aerial parts and litter, and belowground pools included roots and soil C stocks. C outputs monitored were CO2-C emissions, erosion water, and sediment. C balance was considered the difference between inputs and outputs in each treatment during four seasons. The spring and summer seasons had a strong influence on C inputs and outputs where there is significant difference between spring and summer, while the autumn and winter seasons had less influence. All pasture management practices exhibited positive C balance after 1 year. High values of C balance were verified in pastures fertilized (FER) (53.04 Mg ha-1 year-1. Intermediate C balancewas found in the burned (BUR) (40.84 Mg ha-1 year-1), traditional control (CON) (40.31 Mg ha-1 year-1), and in the plowing and harrowing (PH) (40.02 Mg ha-1 year-1) management practices. The practices of chiseled (40.00 Mg ha-1 year-1) and integrated crop-livestock systems (iCL) (59.06 Mg ha-1 year-1) resulted in low C balance.

Combined abiotic stress may harm forage yield due to the direct effects on physiological and production processes. There fore, this study assessed the development of Macroptilium genotypes native to the Brazilian semi-arid region under the combination of water deficit and temperature in crop seasons. The experiments were conducted in 2021 and 2022, using five Macroptilium genotypes and combined water and temperature stress, in factorial 5 × 4 × 2 with five genotypes, four water availabilities (25, 50, 75, and 100% field capacity) and crop seasons (Season 1–high temperature and Season 2–temperature moderate) with four replications. Physiological analyses were performed 30 days after planting, aided by a portable infrared gas analyzer and Chlorophyllometer. Next, cutoffs were made for production assessments (leaf and shoot dry mass, leaf shoot dry mass content, plant dry mass, forage accumulation rate, and water use efficiency). The data were subjected to analysis of variance by the Scott-Knott test and regression for water availability. The interplay between water availability and crop season temperatures exerted a notable influence on the physiological, biometric, and production characteristics of Macroptilium genotypes. Opting for the warmest season for planting proved to be advantageous in enhancing the yield of the genotypes under scrutiny, thereby elevating water use efficiency. Notably, the A59 and L34 genotypes exhibited superior plant dry mass and forage accumulation when exposed to higher temperatures and less than 100% water availability. These findings suggest that A59 and L34 may hold promise as prospective cultivars of Macroptilium sp. with a heightened tolerance to combined abiotic stresses.
