MATHEMATICAL MODEL BY PREDICTING THE DISTRIBUTION OF SOIL MOISTURE IN THE ROOT ZONE OF TURF LANDSCAPE

Abstract

Shahenda yehia Ebrahim Ali El Basha: Mathematical Model By Predicting the Distribution of Soil Moisture in the Root Zone of Turf Landscape. Unpublished M.Sc. thesis, Department of Agricultural Engineering, Faculty of Agriculture, Ain Shams University, 2019. A laboratory experiment was conducted to study the irrigation interval day around effective root zone for turf, used three treatments (spray, SDI and hydrogel) by measuring the moisture content every day in soil and then determine irrigation interval time for every irrigation treatment. The Field experimental was carried out in Faculty of Agriculture, Ain Shams University, Kalubia Governorate , Egypt , Throughout the period from 21/10/2016 to 20/10/2017 (12 months), to construct mathematical model by predicting the distribution of soil moisture content in the root zone of turf landscape . Experimental area of 182.25 divided into 9 plots (4.5*4.5m) for three irrigation treatments ((spray type (nozzles 15) under pressure 2 bar, with discharge 0.8 / hr, SDI (Type of emitters used (built-in) with discharge of 2L/h at 1.0 bar operating pressure) and hydrogel where it is a unique material in terms of its ability to absorb water ) . Each treatment replicated three times , The plants used was one of the landscape plants (passpalm 10 ) at the landscape area and it was new rolls and the roots were short.
