The Nutrient Management Improvement of Rice Culture in the Freshwater Swampland

The new challenge for Indonesian food security in the future depends on productivity of rice sub-optimal land, including freshwater swampland. It is a specific and unique characteristic culture. This study aims to analyze opportunities innovating technology applied improve availability nutrients based existing nutrient soil survey method by purposive random samplings used composite sampling two sub-district Banyuasin District, South Sumatera Province, then analyzed laboratory. Data collected analysis through descriptive statistics. results showed that Rice cultivation swampland was profitable venture. Unavailability P plants main problem acidic (pH 3.32-4.12), caused increased solubility Fe Al. Hence adoption farmers various technological innovations such as liming, fertilization, amelioration increase pH key success culture besides growing tolerant varieties.
