Abstract
Nutrient Balance at Integrated Nutrient Management on Lowland Rice Which is Dominated by 1:1 Clay Mineral for High Potential Rice Yields
Highlights
About 500,000 km2 of acid sulfate soils (ASS) is spread worldwide, and mainly found in coastal zones (Sullivan et al 2012)
A greenhouse experiment was conducted on potentially acid sulphate soils (PASS) that was originated from two types of tidal swampland, i.e.; PASS in type B tidal swampland (PASS-B) and PASS in type C tidal swampland (PASS-C), each of them was set as individual experimental set
The increase of soil pH occurred since the first week until the fourth week of observation especially for P6, which may be related to the presence of Fe-hydr(oxide) in these soils, but in detail, the increase of soil pH in PASSB was higher than in PASS-C
Summary
About 500,000 km of acid sulfate soils (ASS) is spread worldwide, and mainly found in coastal zones (Sullivan et al 2012). Based on the tidal inundation and drainage intensity, tidal swampland is divided into four types, i.e. type A, B, C and D. Type B is the tidal swampland that experiences inundation only at high tide and undergoes draining every day. Type C is the tidal swampland that does not experience inundation even at high or low tide, but undergoes draining every day. Type D is the tidal swampland that does not experience inundation at high or low tide and undergoes a little bit of draining (Kselik 1990)
