10662. Ridley, A.M., W.J. Slattery, K.R. Helyar, and A. Cowling. 1990. The importance of the carbon cycle to acidification of a grazed annual pasture.. Austral. J. Expt. Agric. 30:529-537.
Soil samples were collected to a depth of 60 cm from a 73 year old experiment in Victoria, comparing an unfertilized field to two fertilized fields (4.5 t/ha superphosphate), one of which had also received lime. The soil pH of the fertilized field had declined relative to the unfertilized to a depth of at least 30 cm, while liming appeared to negate the acidification adequately. Carbon and nitrogen cycle acidification accounted for 65 and 35%, respectively, of the net acid addition on the fertilized field.
