In this video, from the Soil Quality Knowledge Base, Daniel Murphy provides data on an 18 year trial studying the effects that burning or retaining crop stubble has on soil carbon and microbial biomass. The trial shows that there is very little difference in the soil carbon % levels between soils that have been burned and soils that have retained stubble. However, the trial showed that soils that retained stubble have a much higher level of biological cycling. This means that crops in these soils receive additional nitrogen and so have improved grain protein levels. While the content focuses on Western Australia, the information is applicable to other Australian regions [2:04].#
This is a carefully curated database of important soil resources. The data base is not exhaustive but rather a library of the resources we believe are the most useful for the audience. Each resource has been added after careful consideration against our selection criteria, including but not limited to its scientific validity, accessibility, and readability. The library generally does not include most academic research papers but may include some open-source papers written in accessible English.
