Abstract: Development of strategies to ensure grazing systems are sustainably produced in harsh environments, while not fertilizing them conventionally, is challenging. Figuring out the extent to which dose of inoculation and period of watering can positively influence the establishment of an effective symbiosis between U. brizantha cv. Marandu and Azospirillum brasilense is the point of this research. The treatment consisted of mixing 1 kg seeds with the inoculant of the strains Ab-V5 and Ab-V6 at 5, 10, 20, and 40 mL kg-1, 2 x 108 CFU mL-1. The plants grew in pots watered 2, 4, 8, and 16 days after sowing over thirty-days, twice. The bioagent at 5?10 mL kg-1 enabled the plants watered up to 4 days after sowing to peak the production of dry mass of shoots (28.50 g) and roots (12.55 g). The efficiency of the symbiosis goes down quickly with increasing dose and delay of watering. Hence, if the dose of inoculant is higher than 10 mL kg-1, it cannot successfully act in plants watered at least 8 days after sowing anymore. In conclusion, A. brasilense can assist in U. brizantha cv. Marandu growth and healthy development unless a lack of water in the substrate and an overdose collectively deter its potential. |

Context: There is little information on the effects of tree densities and ages of silvopastoral systems (SSPs) on total soil carbon stock (TSCS). Aims: This study aimed to evaluate the TSCS, carbon and nitrogen fractionation and biological activity in SSPs planted with Eucalyptus grandis in different densities and ages. Methods: Two SSPs (333 or 166 trees ha?1) and one full sun pasture (FSP) grown for 5 or 7 years and native vegetation (NV) were evaluated (seven treatments). Samples were collected up to 1 m deep to evaluate the variables. Key results: Particulate organic carbon (POC) and particulate organic nitrogen (PON) were higher (P < 0.05) in FSP (14.1 and 0.725 g kg?1), intermediate in SSP (9.88 and 0.46 g kg?1) and lower in NV (6.12 and 0.29 g kg?1). TSCS was 44.8% (194 vs 134 Mg ha?1; P < 0.001) higher in SSP and FSP compared to NV. Higher tree density reduced TSCS in younger systems, but without effect on older systems. TSCS was 13.7% (207 vs 182 Mg ha?1; P = 0.026), POC was 52.0% (11.9 vs 7.83 g kg?1; P < 0.001) and PON was 54.4% (0.556 vs 0.360 g kg?1; P < 0.001) higher in SSP for 7 compared to 5 years, respectively. Conclusions: Tree density had a limited effect on TSCS. Higher SSP age increased carbon sequestration, probably due to greater cycling in the particulate fraction and better biological activity. Implications: The SSP and well-managed FSP are good strategies to increase TSCS compared to NV, and their use can improve environmental indicators. |
