To determine the impact on soil carbon fraction levels of applications of balanced nutrients, N, P and S, stubble retention, stubble removal and stubble incorporation.
The humus portion of soil carbon has relatively constant ratio of N, P and S. This has been established as 80N, 20P and 14S per tonne of humus carbon.
