“…With increasing demands for sustainable food production, how to best utilize the ASS that typify much of South and East Asia remains a significant challenge. To overcome the problems associated with rice cultivation in ASS outlined above, farmers have traditionally applied lime or other chemical neutralizers such as rock phosphate to reduce soil acidity, which has proven to be effective and practical (Von Willert & Stehouwer 2003). However, rice production in ASS is complex (Mathew et al .…”

SUMMARYMost acid sulphate soils (ASSs) in the Pearl River Delta of South China have been traditionally reclaimed for rice cultivation, but the rice yield in most of these paddy fields is lower than the average rice yield in China due to extremely high soil acidity. In the present study, a range of sulphate and acidity parameters were investigated in ASS profiles in three types of paddy fields in Taishan City (Guangdong Province, China) divided based on the local rice productivity (4500, 3000 and 1500 kg/ha) using an abandoned ASS (uncultivated) as the control treatment to ascertain key yield constraining parameters. Soluble acidity (SA), exchangeable acidity (ExA), soluble sulphate (SS) and net acid-soluble sulphate (NAS) increased with increasing soil depths from 0 to 100 cm and then decreased abruptly with further increases in the depth. However, the depth distribution of exchangeable sulphate (ES) was uniform. The soil acidity and sulphate contents differed significantly in three sampled paddy fields. The values of SA and SS in the soils at depths of 0–100 cm in the studied ASS were lower compared with those in the uncultivated ASS and the ExA in soils at depths of 0–40 cm in ASS were lower compared with those observed in the uncultivated ASS. A correlation analysis revealed that SA was strongly correlated with SS and ExA with NAS. Soluble acidity, ExA, SS and NAS in the ASS were significantly associated with rice yield. Exchangeable acidity in the plough layer (0–20 cm) of soils was the most sensitive indicator of soil quality affecting rice yield among those in soils from 0 to 140 cm depth. It is interesting to note that SA, SS and NAS were more sensitive indicators of soil quality affecting rice yield at 60–100 cm than at 0–40 cm depth. Principal component analysis showed that pH value, ExA and ES in soils at depths of 0–40 cm and SA, SS and NAS in soils at depths of 60–100 cm constituted the critical soil acidity and sulphate characteristics that were strongly correlated with rice yields. This finding implies that controlling the ExA in the plough layer and the SA and NAS in the Jarosite layer should be the major focus of studies aimed at the amelioration of ASSs.

Danda Besar Swamp Irrigation Area (SIA) is located in Danda Jaya Village in Rantau Badauh District, Barito Kuala Regency, South Kalimantan Province, Indonesia. It is one of tidal swamp reclamation where tidal fluctuation of Barito River affects to the hydrological condition. Danda Besar SIA has potential agricultural land about 2, 200 ha, and the productivity of paddy field was only 2 ton/ha in average for each time planting year. Two ton/ha is too low productivity due to problem of water quality in irrigation canal. However, fundamental information for the management of water quality of irrigation, monitoring data of water quality, is not measured yet. This fundamental research was conducted to identify and analyze condition of irrigation water quality. The field survey was carried out in dry months, May and June 2021 at primary canal, secondary canal, tertiary canal and pond. The final result for 6 parameters of the 4 locations (primary canal, secondary canal, tertiary canal and pond) showed there were 3 parameters (TDS, DO, and Sulfate (SO4 2-)) fulfill the class II standard, meanwhile there were 3 parameters (pH, Iron (Fe) and BOD) not fulfill the class II standard according to Government Regulation No. 22 year 2021 regarding Implementation of Environmental Protection and Management. The high content of Iron (Fe) and low content of pH recorded in all water sources should be addressed with urgency since this phenomenon as a result of pyrite oxidation affect to pH condition and may cause the low productivity of paddy field.
