Decomposition of wheat straw treated with fungicids

The ordinary fungicid treatment of growing cereals raise the question whether the treated straw would rot more slowly than the untreated one after being ploughed into the soil as an organic fertilizer. An incubation experiment was carried out using straw samples varying in fungicid treatments. These different straw samples of the fungicid trials were incubated in a reference soil under a controlled temperature and moisture regime to discriminate between rates of decomposition measured by the CO2-exhalation.
