Abstract
In many cases the yield and quality of organic rice farming system are better than semi organic and conventional rice farming systems; so many farmers want to move to organic rice farming system. The aim of the study was to evaluate soil fertilities and yield of rice biomass under organic system. The study was conducted in organic rice farming system in Termas Village, Sambung Macan Sub District, Sragen Regency from March 2019 to the end of June 2019. Soil was sampled in March 2019 at organic rice farming system. Composite soil samples were collected from ten sampling points and mixed. These samples were analysed for soil fertilities properties. The results indicated that in general the soil fertility under organic rice farming was superior including pH, C-organic, N total, P and K extracted with HCl 25 %. The same result was found in rice biomass production namely rice grains yield (12.68 tons ha-1season-1), rice straws (7.25 tons ha-1season-1) and rice residues (4.15 tons ha-1season-1)
