Soil organic matter (SOM) and their humic fractions (e.g., Humic Acids, HA) are considered a relevant soil quality indicator, due to its direct relation with biological, chemical and physical soil properties, permitting to evaluate agricultural management impacts. Soils under Integrated Crop-Livestock-Forest Systems (CLFS) have the potential to capture and sequester carbon, in the form of increasing SOM content, contributing to the mitigation of greenhouse gas emissions from agriculture. In this study aimed was characterization the HA extracted from CLFS and Native Forest (NF) soils using elemental analysis (CHN), fluorescence spectroscopy and electronic paramagnetic resonance (EPR). For this, samples of a dystrophic Red-Yellow Latosol (Oxisol) were collected from the experimental site of a research station called Embrapa Pecuária Sudeste (located in the Southeast of Brazil), five years after the implementation of the agricultural integrated systems. Results showed positive correlation between HA humification index with semiquinone-type free radical present in these soils (R = 0.69). Therefore, these results showed that HA from these integrated systems have a more stable and humified soil organic matter than in native forest, contributing to soil carbon compounds with higher chemical stability and possibly with longer lifetime in the soil. |

This study aimed to assess the growth performance and nutritional status of sheep under intermittent water supply by means of performance, intake, apparent digestibility of nutrients, water balance and nitrogen. Thirty-two intact male sheep (20.7 ± 2.63 kg, 8 months of age) were distributed in a completely randomized design with 4 water supply intervals via drinking trough (0h00, 24h00, 48h00, and 72h00), with 8 replicates. The extension in the water restriction period caused a reduction in the intake of dry matter, crude protein, neutral detergent fiber, digestible energy, and metabolizable energy (P < 0.05). The digestibility coefficients of dry matter, crude protein, and neutral detergent fiber showed a linear decrease with increasing periods of water restriction (P < 0.05). Water intake via food, total water intake, and water excretion via feces showed a linear increase in response to an increase in the water supply interval (P < 0.05). Water intake via drinking, metabolic water, total water excretion and water balance presented a linear decrease, with increasing periods of water restriction (P < 0.05). Nitrogen intake and absorbed nitrogen were influenced by water restriction, presenting a linear decreasing trend according to water supply periods (P < 0.05). Final weight, daily weight gain, and total weight gain, were influenced by the periods of water restriction, showing a linear reduction (P < 0.05). Feed conversion increased as the water restriction period increased (P=0.004). Intermittent water supply at intervals of up to 72h00 reduced nutrient intake and digestibility, resulting in a decrease in weight gain of the studied animals.
