Soil properties and classes can influence the occurrence of plants and the production of Brazil nut fruits and may have a different distribution between sites. This study aimed to evaluate the relationship of plants' occurrence, production of Brazil nut fruits, and spatial variability of the properties in different soil classes in two Brazil nut stand in the state of Acre, Brazil. The study was conducted in two plots in two native Brazil nut stand, Cachoeira (CP01 and CP02 - plots 1 and 2) and Filipinas (FP01 and FP02 - plots 1 and 2). The soil profiles were described morphologically. Sixty soil samples were collected in each plot. The chemical properties, granulometry, soil density, particle density, and estimated total porosity were determined. The average fruit production was calculated by counting the fruits in a sample of Brazil nut trees. Subsequently, the trees were divided into three classes of production: low (<-1.5 can; the can unit has 18-L, which is able to hold 59 and 77 fruits, respectively, for Cachoeira and Filipinas), medium (1.6 to 3.9 cans), and high (>-4.0 cans). The can unit is the traditional measure of volume in the region and varies according to the locality. Cluster analysis was performed to determine whether there was a difference between Brazil nut stands and soil profiles, and geostatistics was used to evaluate the spatial dependence of soil properties. The highest occurrence of Brazil nut trees with high fruit production (>-4.0 cans) was found in the Latossolo Vermelho Distrófico argissólico (Oxisol) and Argissolo Vermelho-Amarelo Distrófico típico (Ultisol). However, the Argisol also hosted the plants with the lowest productions (<-1.5 can). The pH, total organic carbon, sum of bases, P, N, granulometry, and porosity showed a greater spatial variability, and FP02 showed a greater number of properties with high spatial variability compared to the other areas. Although the occurrence of plants and the production of Brazil nut fruits (Bertholletia excelsa) were associated with the classes and the physical and chemical properties of the soil, pyxidium production differed between areas. In general, soil physical properties were limiting factors for Brazil nut production and/or higher tree occurrence. Filipinas environment showed a low fruit production and a greater spatial variability of soil properties compared to Cachoeira.

To evaluate the water requirements for Irrigated wheat, a mlcrometeorological study was conducted during the dry seasons of 1982 and 1983 at the Cerrados Agricultural Research Center, Brasilia-DF, BraziL The crop was Irrigated when the soU water potential at 5 cm reached-60 to -7OJIkg. Bowen ratio measurements were made on an hourly basls during the entire crop season, Total amount of water evapotranspired during the crop cycle and the energy balance terms varied year to year due to regional advection; ln 1982,a Iess advective year, the total amount of water evapotranspired was 345 mm, with approximately 80% of the net radlation dlsslpated as latent heat, 13% as a sensible heat and 7% as soU heat after the crop obtalned a Leaf Area lndex (LAI) of 1.5. ln 1983, when advection was greater than 1982, total water evapotranspired Increased to 385mm. The partitloning of energy was similar to 1982 during periods of title or no advecnon, However, during periods of Intense advection, latent heat was greater. In net radlation partitioning. Although regional advection Increased the water used by the crop, Irrigation scheduling based on soíl tensiometers was considered adequate and eflicient due to the low values of the Bowen ratio obtalned. Um estudo núcrometeorológico para avaliar a demanda hídrica do trigo Irrigado foi conduzido nasestações secas de 1982 e 1983 no Centro de Pesquisa Agricola dos Cerrados, Brasilia-DF, Brasil A cultura foi Irrigada quando o potencial de água no solo a 5 cm atinriu -60 a -70 JIkg. Durante todo o ciclo da cultura medidas da razão de Bowen foram feitas numa base horária. A quantidade total de água evapotranspirada durante todo ciclo da cultura e o balanço energético variaram entre os anos devido à advecção regional; em 1982, um ano menos advectivo, a quantidade total de água evapotranspirada foi de 345 mm, sendo 80% da radiação líquida dissipada como calor latente, 13% como calor sensível e 7% como calor do solo após a cultura ter atingido um Índice de Área Foliar (IAF) de 1.5. Em 1983, quando a advecção foi maior que em 1982, a quantidade total de água evapotranspirada aumentou para 385 mm. A partição de energia foi similar à 1982 durante periodos de pouca ou nenhuma advecção. Entretanto durante periodos de Intensa advecção, o calor latente representou a maior parte da radiação líquida. Apesar da advecção regional aumentar o consumo de água da cultura, programação da irrigação baseada em tensiometros foi considerada adequada e eficiente devido aos baixos valores da razão de Bowen obtidos.
