Short summary
Intensification of dairying is rapid in New Zealand, with unknown impact on stocks of soil carbon (C). We investigated changes of soil C over one year for an irrigated, fertilised, rotationally-grazed pasture and an unirrigated winter grazed pasture. The irrigated pasture gained more C from net CO2 uptake, excreta deposition and fertiliser application than was lost by grazing. The unirrigated pasture lost a small amount of C. Intensive dairy practices may thus increase soil C in the short term.
