Land<br>suitability is one of the good management practices for determining appropriate irrigation methods in upland fields.<br>To determine land suitability, various soil experiments as determination of basic physical soil properties,<br>permeability, saturated hydraulic conductivity and soil moisture characteristics method are important. This study<br>was conducted on soil experiment with the aim to provide a detailed comprehensive understanding of soil<br>capabilities for applying certain irrigation methods in two upland fields, broccoli field (BF) and tomato field (TF),<br>in Mie prefecture of Japan. Soil physical structure properties, water holding capacity, and hydraulic properties<br>were determined using disturb and undisturbed soil samples on laboratory bases. The results obtained showed that<br>TF had deeper effective soil layer of 30 cm, better structure (more porosity, better pores connectivity, and<br>channeling), the water holding capacity of 0.082 mm mm-1<br>, and higher hydraulic conductivity, compared to BF. It<br>is concluded that TF is suitable for applying shallow surface irrigation method, while the BF have better response<br>on micro-irrigation methods which prevents water pounding in this fields. Application of this approach can<br>improve irrigation practices and efficiency and decreases water loses through accurate irrigation scheduling and<br>application management of irrigation water in upland field agriculture system, especially in dry areas.<br><br></p> ER -
