Stochastic modeling of soil salinity
[1] A minimalist stochastic model of primary soil salinity is proposed, in which the rate of soil salinization is determined by the balance between dry and wet salt deposition and the intermittent leaching events caused by rainfall events. The long term probability density functions of salt mass and concentration are found by reducing the coupled soil moisture and salt mass balance equation to ...
متن کاملSoil and Water Salinity
Definitions and forms of salinity All natural waters contain soluble salts. The concentration of the salts determines whether the water is of high quality (drinkable or usable for irrigation without need for special precautions) or of low quality (brackish or saline). Water in the soil also contains soluble salts (sometimes called free or nonattached salts). The amount of salts in the root zone...
متن کاملSoil salinity detection using RS data
Soil salinity refers to the state of accumulation of soluble salts in the root zone to adversely affect the growth of most crops. It is a severe environmental degradation that impedes crop growth and production [1]. The conventional processes for the detection, monitoring and mapping of salt-affected soil are known to be difficult and dynamic.(206khan). Remote Sensing has the ability to predict...
متن کاملData Mining and Soil Salinity Analysis
The paper explores connections between decision support systems, remotely sensed and GIS data for environmental planning and monitoring of secondary soil salinisation. The paper introduces a decision support knowledge base system called SALT MANAGER used as the starting point for three experiments in data mining. These experiments structure the paper. In the first, classified GIS data is passed...
متن کاملEffect of initial soil salinity and subirrigation water salinity on potato tuber yield and size
A ®eld lysimeter study was conducted to investigate the effect of initial soil salinity and salinity level of brackish subirrigation water on tuber weight and tuber size of three potato (Solanum tuberosum L.) cultivars (Kennebec, Norland and Russet Burbank) under simulated arid conditions. Both saline and non-saline initial soil conditions were simulated in a total of 36 lysimeters. Eighteen ly...
