Integrated systems have been shown to be viable technology for increase agricultural yields and reduce environmental impact. The enteric methane emissions and milk yields were assessed in crossbred grazing cows in the Cerrado region of central Brazil. Treatments were allocated in a completely randomized design and consisted of two dairy production systems based on Megathyrsus maximus cv. Mombaça cultivated in Integrated Crop-livestock (ICL) or Integrated Crop-livestock-forestry (ICLF). The treatment means were compared using the F test at 5% probability of error. Mombaça grass presented the same forage yield and 22% more CP (P=0.0105) in ICLF. Treatments did not differ for any enteric methane emission variable; however, the cows? fat milk content and fat corrected milk yield (FCM) were, respectively, 7.3% and 9.7% higher in ICLF (P<0.05). In conclusion, crossbred dairy cows produce more FCM in ICLF, with the same methane intensity and production when grazing Mombaça grass under ICL or ICLF systems. |

Our study aimed to evaluate the influence of rubber tree plantations (Clones IAN 873 and FX 3864) on microbial activity, total organic carbon (TOC), and soils chemical attributes, using as reference pasture and secondary forest, in Rio de Janeiro. The plantations areas showed pH; Mg2+, Ca2+, K+ levels; sum of bases; base saturation, basal respiration; metabolic quotient; and arylsulfatase and FDA activities in the soil similar to or greater than the values found in the forest. In contrast, showed lower P and TOC levels; carbon and nitrogen in the microbial biomass; and Beta-glucosidase activity than of forest and pasture. Higher acid phosphatase and laccase enzymes activities was observed in the forest and plantations than in the pasture. Thus, we verified that the rubber tree plantations (Clones: IAN 873; FX 3864) maintain or improve the quality of some chemical and microbiological attributes of the soil regarding secondary forest and pasture. |
