Abstract. The input of liquid water to terrestrial ecosystems is composed rain and non-rainfall (NRW). latter comprises dew, fog, the adsorption atmospheric vapor on soil particle surfaces. Although NRW inputs can be relevant support ecosystem functioning in seasonally dry ecosystems, they are understudied, being relatively small, therefore hard measure. In this study, we apply a partitioning r...

Abstract The objective of this work was to determine the accumulation silicon in plant components cauliflower (Brassica oleracea var. botrytis) grown with different levels water replacement and rates Si. experimental design a randomized complete block three conditions (40, 70, 100% evapotranspiration), four Si (0, 50, 100, 150 kg ha-1), replicates. Daily evapotranspiration determined constant t...

a field study was conducted to evaluate the possibility of using water table control techniques in the semi arid region of iran with special attention to its salinity management. the wtm consisted of three subirrigation treatments with water table controls set at 0.3, 0.5 and 0.7 m from the soil surface and a free drainage (fd) treatment. the electrical conductivity (ec) of water was 1.5 ds/m. ...

Disrupting ecosystem components, while transferring and reconstructing them for experiments can produce myriad responses. Establishing the extent of these biological responses as the system approaches a new equilibrium allows us more reliably to emulate comparable native systems. That is, the sensitivity of analyzing ecosystem processes in a reconstructed system is improved by excluding the per...

To better understand the impact of conventional agricultural practices on soil and water resources, two main objectives were established in this study: to measure nitrate (NO3-) sulphate (SO42-) concentrations lysimeters drainpipes leachates response different nitrogen fertilization levels amendments identify organic contaminants that could have originated from long-term use agrochemicals histo...
