“…By the criteria of Warrick and Nielsen (1980), this variability can be classified as medium in the first three crop stages and high for the end of the cycle. In addition, data variation was much higher in the last period, when rainfalls were recorded, confirming that the greatest variations in the internal drainage process occur in the periods of greatest rainfall (Ghiberto et al, 2011b).…”

“…The K(θ) and at 0.2 and 0.9 m soil depth were calculated from weekly readings of tensiometers installed at depths of 0.15, 0.25, 0.85 and 0.95 m. The tensiometer readings were monitored for 36 months (Feb 2009to Jan 2012. To calculate the soil water flux density, we determined the soil water retention curve to obtain the soil water content from tensiometer readings and then the soil hydraulic conductivity K from the equation of K as a function of volumetric water content obtained at both depths (0.2 and 0.9 m) by the instantaneous profile method (Ghiberto et al, 2011).…”

High productivity of eucalypt plantations is the result of advances in research that have led to gradual improvements in intensive silvicultural technology. High productivity notwithstanding, eucalypt plantations remain the focus of environmental concerns. Our study aimed to compare the soil water regime, litter fall and nutrients dynamics either in a fragment of native forest or in an adjacent stand of growing eucalypt. We took field measurements during the first three years of eucalypt plantation in a sandy soil in the southeastern region of Brazil. Soil moisture and internal drainage were higher during the early stages of growth of the eucalypt stand, as compared with native vegetation. However, one and a half years after planting, available soil water was similar in both vegetations. Higher water availability under the eucalypt stand during the first year occurs because of silvicultural operations (soil preparation and weed control) and the small size of eucalypt trees; these factors increase water infiltration and decrease transpiration. Total leaf fall, over the study period, was similar for both ecosystems; however, differences were observed in the winter and early spring of 2010. The transfer of nutrients to soil by leaf fall was similar except for N and S, which was higher in native vegetation. Nitrogen concentration in the soil solution was higher in native vegetation, but K was higher under the eucalypt stand, mainly to a depth of up to 0.2 m.

“…Soil water dynamics provides essential knowledge for agricultural management practices during different phenological stages for crop yield improvement (Zougmoré et al, 2004;Ghiberto et al, 2011), whereas ET provides important information for water management both in irrigated and dry soil conditions. However, records on ET data for forage cactus are few around the world and practically non-existent in the Brazilian semiarid region, where this crop is of great economic importance (Oliveira et al, 2010).…”

-The objective of this work was to evaluate soil water dynamics in areas cultivated with forage cactus clones and to determine how environmental conditions and crop growth affect evapotranspiration. The study was conducted in the municipality of Serra Talhada, in the state of Pernambuco, Brazil. Crop growth was monitored through changes in the cladode area index (CAI) and through the soil cover fraction, calculated at the end of the cycle. Real evapotranspiration (ET) of the three evaluated clones was obtained as the residual term in the soil water balance method. No difference was observed between soil water balance components, even though the evaluated clones were of different genus and had different CAI increments. Accumulated ET was of 1,173 mm during the 499 days of the experiment, resulting in daily average of 2.35 mm. The CAI increases the water consumption of the Orelha de Elefante Mexicana clone. In dry conditions, the water consumption of the Miúda clone responds more slowly to variation in soil water availability. The lower evolution of the CAI of the IPA Sertânia clone, during the rainy season, leads to a higher contribution of the evaporation component in ET. The atmospheric demand controls the ET of clones only when there is higher soil water availability; in this condition, the water consumption of the Miúda clone decreases more rapidly with the increase of atmospheric demand.Index terms: Nopalea, Opuntia, CAM photosynthetic pathway, evapotranspiration.
