“…Similarly, ref. [24] found the highest rates of ET in the summer, December and February, in sugarcane and eucalyptus plantations and native areas of Cerrado and Atlantic Forest. Furthermore, these higher ET values related to the tree strata may be due to greater height, deeper roots [25], in addition to greater biomass production.…”

The balance between precipitation and evapotranspiration (ET) has direct effect on vegetation, and any change in its structure and composition can influence it. The aim of this study is to determine experimentally the daily evapotranspiration (ET) of the invasive species, Hedychium coronarium, and to compare with a group of four native species of the riparian forest. The experiment was carried out in a greenhouse with three different treatments: (1) only the invasive species; (2) only native species; and (3) a mixture of invasive and native species. In each lysimeter, pressure transducers recorded the water level at every 15 min along 14 months. Daily ET was calculated by the method of Gribovszki et al. (2008) and varied according to the treatment, indicating that different species (invasive or native) use the water differently. The maximum accumulated daily ET occurred for mixture treatment (2540.16 mm), while the treatment with the invasive plant presented the lowest value (2172.53 mm). H. coronarium, in monodominant stands, can reduce evapotranspiration on invaded areas and increase it when immersed in the riparian forest.

“…This biologically driven control on surface gas fluxes observed here for a very modest biome (see ) accounted for ∼10% of the variations of the flux. It could well be much higher for larger biomes, such as meadows or forests, because it scales with the intensity of evapotranspiration and root respiration (Bosquilia et al., 2019; Pauliukonis & Schneider, 2001). Also, microbiological activity known to be active in natural soils would enhance the respiration effect, whereas it is much more likely limited in our studied case of a model soil consisting of washed pure silica sand.…”

Modulations of advective gas fluxes at the soil-atmosphere interface were investigated using an enhanced experimental setup developed to perform tracer gas percolation experiments through unsaturated soil columns under well-controlled conditions associated with long-term and high-resolution monitoring. The setup design includes the effect of watering and evaporation cycles, barometric pressure fluctuations, variations in the injection pressure, and plant metabolism. Although injected at a constant flux at the base of the columns, SF 6 surface fluxes varied on a timescale of hours to days. These modulations are controlled by (a) barometric pressure, (b) water content and distribution, and (c) plant metabolism. All three mainly act on the pressure gradient. Surface gas fluxes decrease under drying conditions, which increases gas porosity and the relative gas permeability and lowers the pressure gradient. Respiration of plant roots is shown to be responsible for daytime-nighttime oscillations of the tracer flux. During nighttime, O 2 consumption and CO 2 production locally lowers the pressure gradient up to the root zone due to the higher solubility of CO 2 in pore water, resulting in an increased SF 6 flux at the surface. During daytime, enhanced water loss by evapotranspiration associated with photosynthesis dominated the respiration effect and resulted in decreasing surface gas fluxes, as generally shown for drying conditions. Surface gas fluxes are therefore controlled by combined physical, chemical, and biological processes. This has important consequences, notably when discrete flux measurements are integrated in space and/or in time to quantify emissions or when used for detecting, identifying, or monitoring underground gas sources.

A evolução da tecnologia da irrigação associada aos aspectos agronômicos permitiu um avanço no entendimento do sistema de produção e, com isso, o desenvolvimento da agricultura irrigada, onde a produção vegetal está associada a um novo paradigma, envolvendo a escolha de uma rotação de cultura adequada do ponto de vista agronômico, comercial e da sustentabilidade. O sistema de produção passou a exigir diferentes estratégias caracterizando que a agricultura irrigada é distinta da agricultura de sequeiro mais aplicação de água. Questiona-se não só o que plantar, mas também qual variedade cultivada seria mais adequada a disponibilidade permanente da água, possibilidade de organizar o calendário de cultivos com vista a um melhor atendimento do mercado, novos critérios de planejamento da fertilização da cultura e dos tratamentos fitossanitários, com o uso da quimigação como uma das suas principais tecnologias que é a fertirrigação. Para isso, foi fundamental o incentivo e a apropriação das inovações que cada dia permitem uma melhor condução e acompanhamento do sistema produtivo. Os temas inovação, empreendedorismo e sistemas de produção sem vírgula são tratados dentro das diferentes abordagens da agricultura irrigada no Brasil, constituindo uma importante contribuição para o desenvolvimento sustentável da agricultura irrigada brasileira e mundial.
