Kajian Efisiensi Penyimpanan Air dari Berbagai Tekstur Tanah

Abstract

Water storage efficiency showed the water irrigation that meet crop needeed in terms of water demand in the growing media and the media's ability to hold water. To determine the amount of water retained in the soil, it is necessary to study water storage efficiency in a variety of soil texture were to determine the ability of water storage in loam, clay loam, and sandy loam soil textures. The study was conducted using a completely randomized experimental design (CRD), which consist of three soil texture, i.e. sandy loam, loamy clay, and loam with 5 replications. Data analysis was performed using analysis of variance (ANOVA), Duncan-test, and bar charts. The results showed loam soil texture is the most efficient in holding water. The amount of water that can be held was 11566 mm with 46.3% efficiency storage. Clay loam can hold 9340 mm water with holding efficiency 37.4%, while sandy loam 7786 mm and 31.2%. Having the ability to retain water in the soil texture known, water applied to soil should not exceed the ability of the soil to hold water. If the aplication exceeds the capacity, the water supplied is not efficient.
