Automation of irrigation by electronic tensiometry based on the arduino hardware platform

open access: yesRevista Ambiente & Água, 2020
This study developed and evaluated an electronic irrigation system controlled by soil water matric potential. The controller uses tensiometers and pressure transducers as a reading mechanism, integrated with an Arduino microcontroller board that drives ...

Saturation‐matric potential relations in gravel [PDF]

open access: yesWater Resources Research, 2002
Some environmentally sensitive unsaturated zone sediments, such as those underlying radioactive waste tanks in Hanford (Washington State), contain large fractions of gravels and coarse sands. Coarse, granular media are also included in designs of engineered capillary barriers for subsurface waste isolation.

Effect of Water Potential on Germination of Verticillum dahliae microsclerotia

open access: yesPhytopathologia Mediterranea, 2006
The effects of osmotic and matric potentials on the microsclerotial germination of Verticillium dahliae was examined at room temperature in 1% water agar amended with sodium chloride and polyethylene glycole.

Intrinsic Relationship between Matric Potential and Cation Hydration

open access: yesVadose Zone Journal, 2016
Core Ideas Exchangeable cations are important in water sorption, hydraulic conductivity, swelling, flocculation–deflocculation, and fertility. Intrinsic relationship exists between matric potential and cation hydration at very low water contents ...

Interpolation of multidimensional diabatic potential energy matrices [PDF]

open access: yesThe Journal of Chemical Physics, 2006
A method for constructing diabatic potential energy matrices by interpolation of ab initio quantum chemistry data is described and tested. This approach is applicable to any number of interacting electronic states, and relies on a formalism and a computational procedure that are more general than those presented previously for the case of two ...

Effect of water potential on sclerotial germination and mycelial growth of Macrophomina phaseolina

open access: yesPhytopathologia Mediterranea, 2008
The effect of the osmotic (Ψs) and matric (Ψm) potential on the sclerotial germination and mycelial growth of Macrophomina phaseolina was examined at room temperature. Sclerotial germination was determined in 0.1% water agar and mycelial growth on potato
