A castanha-do-brasil (Bertholletia excelsa Bonpl.) é uma espécie que se destaca na região amazônica, por ter uma importante função econômica, ecológica e social. A espécie tem grande potencial silvicultural para reflorestamentos com fins madeireiros ou para produção de frutos, também pode ser considerada apta a compor sistemas agroflorestais. O objetivo deste estudo foi o de analisar dados de atributos químicos do solo (pH e P) e comparar alterações durante o desenvolvimento do plantio em Machadinho d`Oeste, Rondônia. Para determinação das características químicas do solo foram realizadas coletas de amostras de solo antes do plantio e ao longo do tempo, sendo os atributos analisados, pH em água 1:2,5; P, K, Ca, Mg, Ca+Mg, Al+H, Al, M.O. e V%. Pelas análises dos dados, observou-se que não ocorreram alterações significativas nos atributos químicos do solo na área do experimento, ao longo dos 28 anos de avaliação, o crescimento foi satisfatório em DAP, sendo indicada para plantios em áreas degradadas, como elemento da recomposição florestal. |

This study employed infrared thermography to assess the thermoregulatory responses of female buffaloes reared in a hot and humid climate as a function of variations in time and the thermal environment, and to correlate rectal temperature with that of different body areas. The trial was carried out at Embrapa Eastern Amazon (01°26'S and 48°24'W) in Belém, PA, Brazil. Twenty-four female buffaloes fed exclusively on pasture and exposed to the sun throughout the day in an open area were used. The animals were taken back to the corral at 6 A.M., 9 A.M., 12 P.M., 3 P.M., 6 P.M., and 9 P.M. for measurements of rectal temperature (RT), respiratory rate (RR), and body surface temperature (BST) using infrared thermography (IRT). Data on air temperature (AT), relative air humidity (RH), wind velocity (WV), and solar radiation (SR) were also recorded. A quadratic effect of AT, RH, SR, RR, and RT (P < 0.01) was found as a function of measurement time. Between 12 P.M. and 3 P.M., AT, SR, RR, and RT values were the highest, while RH values were the lowest (P < 0.05). WV was the highest between 12 P.M. and 9 P.M. A difference was found in RR and RT among the day's times, with the highest values at 12 P.M. and 3 P.M. (P <0.05). The IRTs have a quadratic effect as a function of day's times, with the highest levels between 12 P.M. and 6 P.M. and a reduction at 9 P.M. All IRTs are correlated with the physiological variables RR and RT, except for the IRT of the side of the back, which is not correlated with RT. The IRTs of the eye and cheek are correlated with RT (P < 0.01) and with RR (P < 0.05). IRT was efficient in evaluating the thermal stress of female buffaloes in hot and humid climates, and the technique can be used to evaluate the body temperature of these animals, since the RT was positively correlated with the temperature of the eye and cheek.
