Integrated Assessment of Irrigation Water Quality Based on Harrington's Desirability Function
Abstract
It was proposed the integrated approach to the irrigation water assessment as its quality index IWQI. This criteria is united the quantitative assessment of different risks such as soil sodicity, plant toxicity, biofilm formation in drippers of irrigation systems etc. It is proposed to combine agronomic, ecological and technological requirements to the irrigation water using a generalized Harrington's desirability function (HDF). Within the framework of this concept, it was developed the scales of particular HDF for physico-chemical indicators, SAR values, and the Stebler's irrigation coefficient. IWQI was determined for the assessment of water quality for irrigation purpose on the examples of 3 dug wells located on the Agronomic Experimental station of National University of Life and Environmental Sciences of Ukraine (Pshenichne village, Kiev region). It is shown that water quality varies considerably (from 56 till 85%).
