3 Introduction Soil water characteristics, e.g., field capacity, soil water tension at FC, and permanent wilting point Soil water release processes 3
4 Objectives To propose a new method of calculating field capacity from the van Genuchten Model To evaluate the irrigation scheduling generated from van Genuchten Model and compare the results with those from water balance equation 4
5 Objective 1. Calculating Parameters of Soil Water Status Using van Genuchten Model Methods - Assumption 1 Soil water content at the inflection point of the van Genuchten Model is assumed to be the situation of texturedominant pores (large and small) filled with water. Reynolds, et al Use of indicators and pore volume-function characteristics to quantify soil physical quality. Geoderma 152: van Genuchten, M.T A closed-form equation for predicting the hydraulic conductivity of unsaturated soils. Soil Sci. Soc. Am. J. 44:

14 Conclusions Reliable calculatioin of FC from van Genuchten Model Use of van Genuchten Model in irrigation scheduling FC, SWT at FC, and PWP Soil water release processes 14
15 Future work To calibrate the irrigation scheduling To simplify the procedure by soil texture To input the information into precision irrigation systems. 15
