Proses pencucian dengan drainase ba

Proses pencucian dengan drainase bawah permukaan diperlukan dalam menangani masalah salinitas di lahan pertanian. Tujuan penelitian ini adalah menentukan laju pencucian garam dalam tanah melalui percobaan aliran kontaminan dalam tanah, dan mengetahui kesesuaian formuls yang dituliskan ILRI (1994) dalam menentukan laju pencucian. Tahapan pengumpulan data terdiri atas percobaan sifat fisik tanah, kontaminasi garam, dan pencucian tanah. Hasil percobaan menunjukan bahwa setiap laju perkolasi membutuhkan waktu pencucian yang berbeda, yaitu 0,07, 0,13 dan 0,08 hari untuk laju perkolasi 1035,73, 1614,12 dan 1888,52 mm/hari. Hal ini dipengaruhi oleh konsentrasi garam terlarut (Ct), laju perkolasi (q), kemampuan tanah dalm menyimpan (Wfc) dan meloloskanair (K). Namun hasil tersebut berbeda bila dihitung secara teori, sehingga untuk kondisi tanah dan metode yang digunakan seperti dalam proses penelitian perlu adanya pengembangan terhadap formula yang dikeluarkan oleh ILRI (1994), yaitu dengan menambahkan koefisien koreksi untuk nilai Wfc sebesar 0,076, 0,078, dan 0,042 untuk percobaan 1, 2, dan 3 guna memperoleh hasil perhitungan yang lebih sesuai dengan kondisi sebenarnya.

The process of leaching with subsurface drainage is needed in dealing with the problem of salinity in farmland. The purpose of this study was to determine the rate of leaching of salts in the soil through experiments the flow of contaminants in the soil, and know the suitability of formuls rendered ILRI (1994) in determining the rate of leaching. The stages of data collection made up of soil physical properties, experiment Salt contamination, and leaching of soil. The experiment results show that each leaching rate of perkolasi takes a different path to 0.07, 0.13 and 0.08 today to rate perkolasi 1035,73, 1614,12 and 1888,52 mm/day. This is affected by the concentration of dissolved salts (Ct), the rate of perkolasi (q), the ability of the land in respect of save (Wfc) and meloloskanair (K). But the results are different when measured in theory, so to soil conditions and the methods used such as in the process of research is need for the development of the formula issued by ILRI (1994), i.e. by adding value to the correction coefficient of Wfc 0,076, 0,078, and 0.042 for experiments 1, 2, and 3 the calculation results to get more in line with actual conditions.

The process of leaching with subsurface drainage is needed in dealing with the problem of salinity in agriculture. The purpose of this study was to determine the rate of leaching of salt in the soil by the flow of contaminants in the soil experiments, and determine suitability formuls written ILRI (1994) in determining the rate of leaching. Stages of data collection consisted of experimental physical properties of soil, salt contamination, and soil leaching. The experimental results showed that each of the rate of percolation leaching takes a different, namely 0.07, 0.13 and 0.08 days for the percolation rate of 1035.73, 1614.12 and 1888.52 mm / day. It is influenced by the concentration of dissolved salts (Ct), the percolation rate (q), the ability of the soil store preformance (WFC) and meloloskanair (K). However, these results differ when calculated in theory, so as to soil conditions and methods used in the research process as necessary to the development of the formula issued by ILRI (1994), by adding the correction coefficients for WFC value of 0.076, 0.078, and 0.042 for Experiments 1, 2, and 3 in order to obtain calculation results more in line with actual conditions.
