Webb3 jan. 2024 · This work arises from the need of exploring new features for modeling and optimizing water consumption in irrigation processes. In particular, we focus on water flow model in unsaturated soils, accounting also for a root water uptake term, which is assumed to be discontinuos in the state variable.

Webb17 mars 2015 · Those with RSC values greater than 2.5 meq/L (RSC > 2.5 meq/L) are said to be unsuitable for irrigation (Eaton 1950; Richards 1954). In this study, 56 % of the samples are safe for irrigation, 34.78 % are marginal and would require great care in its usage. The remaining 8.7 % are unsuitable for use as irrigated water.
