A comparison of the dynamics and carbon stocks in rice fields with different management systems and soil types

Paddy fields in Indonesia, on average, have a very low content of organic matter (organic C < 2%). This matter’s will affect the carbon stock. The management system as well soil type could stock soil. study aims to determine dynamics and paddy with different systems types. research was conducted Karanganyar Regency; Sukoharjo Regency Klaten Regency. Factors observed include organic, semi-organic, inorganic types (i.e., ultisol, vertisol inseptisol). Soil sampling carried out 3-5 days after harvest. Each combination taken three sample points at two depths (0-20 cm > 20 cm) repeats. parameters hedied C, dissolved microbial pHH2O, total N, CEC, texture bulk density. depth interaction C. Total is highest soils an (2.59%) 0-20 (2.24%). Carbon (82.62 tons ha-1) higher than semi-organic systems, 71.19 ha-1 68.4 ha-1.
