Abstract

The research about residue effect of hurnic acid from imperata cotnpost and water management to decrease the dissolved of iron (fe) on recently used rice field had been conducted from march till august 2007. The objective is to study residue effect of hurnic acidity application and water management to controlling Fe and to increase rice production on recently used rice field. The experiment using design factorial 2 x 4 with three replication wich is place as the split plot. The major factor is water management consisted of two treatment, thos were continuously flooded (P1) and flooded and dried (intermittence) with two week interval (P2). The minor factor are four level from residue effect of humic acid (0, 200, 400, 600 ppm). The result of this study can provided the information that residue effect of humic acid at 600 ppm can reduce solubility of,Fe2* from327,9l to 37,53 ppm for continously flooded and from 173,51 to 38,13 ppm for intermittence flooded. And the yield of rice (dry weight of 1000 grain ad straw) increase as much as 4,9 and 5,38 g with residue effect of humic acid at 600 pprn combination with intermittence flooded.
