| | | Measured | Soil C stocks of Peanut-Maize cropping system after clearing native scrub vine after 55 years of cultivation in Red Ferrosols In South East Queensland | Original land use was native scrub. In 1950 some lands with native scrub was cleared and has been continuously cultivated to peanut-maize, with heavy use of machinery and agrochemicals. It is purely a traditional cultivation system. | The predicted rate of change in total soil C should be applied only to Red Ferrosol soils in the South East Queensland environment (please see regional condition for this). It can be applied in Red Ferrosol soils which has been cultivated with peanut-maize cropping since last 55 years. | In the research area, mean monthly rainfall is always lower than mean monthly evaporation; therefore, soil moisture is the major limiting factor. The soil is classified as a Red Ferrosol according to the Australian Soil Classification of Isbell (2002), or a Tropeptic Eutrustox (i.e., Oxisol) in the USDA Soil Taxonomy. Research site (Kingaroy) is situated approximately 215 km (133.6 mi) northwest of Brisbane and some 130 km (80.8 mi) inland from the coast. Elevation at Kingaroy is 441 m (1,446.5 ft) above sea level. The climate is classified as subtropical, with long summers and mild winters. Annual rainfall varies from 339 to 1,430 mm (13.3 to 56.3 in), with an average of 781 mm (30.7 in), and is summer-dominant with about 70% falling between October and March. Frosts also occur during winter. June, July, and August are the coldest months and on average Kingaroy has 24 heavy and 22 light frosts each year. The hottest months are December-January, averaging only 10 days between them over 32 degrees Centigrade (89.6 deg F ) and usually only one day over 38 degrees Centigrade (100.4 deg F ). The yearly average maximum temperature is 24.7 degrees Centigrade (76.5 deg F ), while the yearly average minimum is 11.4 degrees Centigrade (52.5 deg F ). | | | 38 | tonnes C/ha | Peer-reviewed journal | |
