Abstract

NANDA AKBAR SIREGAR: Study The Permeability of Some Soil Types in Field Trials USU Kwala Bekala Through Laboratory Tests and Field, under supervision of SUMONO dan ACHWIL PUTRA MUNIR. Soil permeability is the ability to pass water in saturated conditions. Some types of soil in field trials USU Kwala Bekala have different permeability rate. It is caused by several factors including texture, organic matter content, porosity and effective depth of soil. Measurement of soil permeability is very important to some interest in agriculture, such as the entry of water into the soil, water movement to plant roots, and the flow of drainage water. Thus necessary to study more about the permeability. This study aimed to determine the value of some types of soil permeability rate through laboratory and field testing. Of the results of research in the laboratory permeability values obtained rate of 1,34 cm/hr at ground Andepts, 3,20 cm/hr at ground Inceptisol, and 1,06 cm/hr at ground Ultisol. Of the results of research in the field permeability values obtained rate of 1,26 cm/hr at ground Andepts, 2,23 cm/hr at ground Inceptisol, and 0,98 cm/hr at ground Ultisol.
