This study evaluated beef cattle performance, nitrogen (N) dynamics, and potential greenhouse gas emissions (GHG) in tropical pastures receiving N fertilization or mixed with legumes. During the cool season, 54 Nellore heifers were randomly allotted to continuous grazing in three plots of each pasture type: T1 (Marandu grass with 150 kg N/ha), T2 (Marandu grass with 120 kg N/ha), T3 (Marandu grass with Arachis pintoi), T4 (Marandu grass with Desmodium heterocarpo), T5 (Marandu grass without N fertilization), and T6 (degraded pasture). The stocking rate was periodically adjusted to achieve the target canopy height of 20?25 cm. Animal performance and N livestock excretion were estimated by variation in live weight and spot samples of urine and feces, respectively. GHG emissions were calculated using the methodology of the Intergovernmental Panel on Climate Change. Animal performance was higher in fertilized and mixed pastures (e.g., T1 to T4) than in T5 and T6 pastures. Heifers grazing on T1, T2, T3, and T4 excreted lower amounts of urine with higher N concentrations than heifers grazing on T5 and T6. Heifers grazing in T2 and T4 pastures had a lower concentration of fecal N than those grazing on other pastures, reflecting lower N excretion in this form. The potential for direct nitrous oxide emissions per unit area in pastures mixed with legumes was approximately four times lower than that in pastures with mineral N fertilization. The recovery of degraded pastures and the inclusion of forage legumes contributed to maintaining the sustainability of animal production in pastures.

Soil organic matter accumulation provides benefits to soil productivity and reduces atmospheric carbon concentration. However, little is known about the accumulation of C and N by sandy soils under perennial irrigated crops in semiarid regions. The objective of this study was to evaluate the effect of irrigated fruit orchard cultivation on the stocks of soil organic carbon (SOC) and total nitrogen (N) of an Arenosol/Quartzpsament from Paraipaba-CE, Semiarid Brazil. Soil samples were taken from irrigated orchards of banana (Musa ssp.), cashew (Anacardium ocidentale), guava (Psidium guajava), bullock's heart (Annona reticulata), mango (Mangifera indica), and sapote (Manilkara zapota) in the wetted-bulb and non-irrigated area between the plant rows. Additional samples were collected from adjacent areas under secondary Caatinga forest, and under a 2-year-old deforested area. Sampling depths were: 0-0.1, 0.1-0.2, and 0.2-0.4 m. The highest contents of SOC and N were found in the surface layer. The soil bulk density did not change in depth. The stocks of SOC and total N under secondary forest at 0-0.40 m layer were 27.6 and 2.4 Mg ha-1, respectively. Caatinga Forest conversion into fruit orchard cultivation led to a decrease of 5 to 23% and 4 to 21% on SOC and N stocks, respectively. Compared to other soil uses, sapote and bullock's heart contributed for a lower decrease of SOC and N stocks after deforestation. Guava, bullock's heart, mango and sapote contributed for improving the SOC stratification index. O acúmulo de matéria orgânica beneficia a produtividade do solo e reduz a concentração do carbono atmosférico. Entretanto, pouco é sabido a respeito do acúmulo de C e N em solos arenosos cultivados com culturas perenes irrigadas em regiões semi-áridas. O objetivo deste trabalho foi avaliar o efeito do cultivo de fruteiras irrigadas nos estoques de C e N de um Neossolo Quartzarênico em Paraipaba, CE. Foram coletadas amostras na linha e na entrelinha de pomares irrigados de banana, caju, manga, sapoti, goiaba e graviola. Em áreas adjacentes sob vegetação de Caatinga hipoxerófila e após dois anos de desmatamento foram coletadas amostras adicionais. As profundidades de amostragem foram: 0 a 0.1, 0.1 a 0.2 e 0.2 a 0.4 m. Os teores de C e N no solo foram mais altos na camada superficial (0 a 0.1 m). Não houve efeito da profundidade de amostragem sobre a densidade do solo. Os estoques de C e N na área com vegetação de Caatinga na camada de 0 a 0.4 m foram de 27,6 and 2,4 Mg ha-1, respectivamente. A retirada da vegetação natural e o cultivo das fruteiras levaram a reduções de 5 a 23% e 4 a 21% nos estoques de C e N do solo, respectivamente. As culturas do sapoti e da graviola contribuíram para o aumento dos estoques de C e N após a retirada da vegetação natural.
