dc.description.abstract | The purpose of the research is to identify the current condition of land fertility; for improvement and sustainability of land productivity, and for sustainable management actions. The research was carried out by taking 5 soil samples in 10 plots of rainfed rice fields, tidal rice fields and swamp rice field that had been determined, using a soil drill with a depth of ±30 cm; took 1 kg compositely from each of 5 samples and analyzed at the Laboratory of Soil Science, Faculty of Agriculture, Mulawarman University. The results of laboratory analysis provide information that: 1). Rainfed rice fields show, on average: C-organic content in moderate status (2.08%), Total N content in moderate status (0.34%), C/N ratio in low status (6.28), pH value in very acidic status (4.48), organic matter content, in moderate status (3.57%). 2). Tidal rice fields, showing the average: C-organic content in high status (3.27%), Total N content in moderate status (0.41%), C/N ratio in low status (7.89), pH value in very acidic status (4.28), organic matter content, in moderate status (3.58%); 3). Swamp Rice field, shows the average: C-organic content in high status (3.06%), Total N content in moderate status (0.46%), C/N ratio in low status (6.84), pH value in very acidic status (4.25), organic matter content, in high status (5.26%). | en_US |
