| The present study aimed to evaluate the fermentation kinetics and degradation rates of Cynodon grasses estimated by semi-automated technique of in vitro gas production. The forages were: Coastcross, Tifton 85 and Tifton 68. Pressure readings were taken at 0, 2, 4, 6, 8, 10, 12, 15, 19, 24, 30, 36, 48, 72 and 96 hours. Dry matter degradability (DMD) was obtained by the percentage of dry matter (DM) remaining after 0, 6, 12, 24, 48 and 96 hours of fermentation. Tifton 85 showed a higher total gas production (p <0.05). Higher fermentation rates were found at the beginning of fermentation followed by subsequent reduction (p <0.05) over time. Tifton 85 and Tifton 68 showed higher values (p < 0.05) for soluble fraction, potentially degradable insoluble... |

| The experiment was conducted in Eutrophic Red-Yellow Ultisol, and aimed to evaluate soil chemical properties in ICLF systems compared with other types of soil use. The study assessed ICLF systems, monocultures of acacia (Acacia mangium), Eucalyptus (Eucalyptus urophylla x E. grandis), Urochloa Brizantha, Urochloa decumbens, Sorghum bicolor and Panicum maximum, with crop variations in three agricultural cycles in a 2 year period, compared to native vegetation, 8-year-old U. Brizantha pasture and degraded pasture of P. maximum with areas of exposed soil. Compared to native forest and well-managed pastures and ICLF systems, contents of organic matter and calcium in the soil were lower in monocultures of eucalyptus, acacia and forage. The fact that the soil... |
