Soil Electrical Conductivity and Soil Salinity: New Formulations and Calibrations

- J. Rhoades, Nahid A. Manteghi, P. Shouse, W. Alves
- Environmental Science
- 1 March 1989

A new model describing the relation between bulk soil electrical conductivity (EC,), volumetric content (0W) and electrical conductivity of soil water (EC») is given along with supporting evidence… Expand

Scaling Parameter to Predict the Soil Water Characteristic from Particle-Size Distribution Data

- L. Arya, F. Leij, M. T. Genuchten, P. Shouse
- Mathematics
- 1 May 1999

The Arya-Paris model is an indirect method to estimate the soil water characteristic from particle-size data. The scaling parameter, α, in the original model was assumed constant for all soil… Expand

Identifying Soil Properties that Influence Cotton Yield Using Soil Sampling Directed by Apparent Soil Electrical Conductivity

Crop yield inconsistently correlates with apparent soil electrical conductivity (EC a ) because of the influence of soil properties (e.g., salinity, water content, texture, etc.) that may or may not… Expand

Relationship between the Hydraulic Conductivity Function and the Particle‐Size Distribution

- L. Arya, F. Leij, P. Shouse, M. T. Genuchten
- Materials Science
- 2003

We present a model to compute the hydraulic conductivity, K, as a function of water content, θ, directly from the particle-size distribution (PSD) of a soil. The model is based on the assumption that… Expand

In situ use of groundwater by alfalfa

Disposal of saline drainage water is a significant problem for irrigated agriculture. One proposal is to recycle drainage water to irrigate salt tolerant crops until the volume has been reduced… Expand
