Cultivation of upland rice in degraded estuarine lagoon spoils, with emphasis on the chemical properties of the sediment



Cultivation of upland rice in degraded estuarine lagoon spoils, with emphasis on the chemical properties of the sediment



Journal of Environmental Management 29(2): 115-128



Dredged lagoon sediments from the Nanakita river, polluted with 7000 t carp pond effluent/d, with domestic waste and secondarily treated wastewater from a town of 20 000 people 20 km upstream and with paddy soil and inorganic nutrients, were buried in a sand bar and upland rice was grown in trenches 2 m apart with seedlings planted 30 cm apart. Some trenches were not given fertilizer whereas others were given 44 kg N, 88 kg P2O5 and 88 kg K2O/ha. The C:N ratio of the sediment was 8.0-10.0.
