The in situ coupling between electrochemistry and spectrometric techniques can help in the identification and quantification of the compounds produced and consumed during electrochemical reactions. Th... ... Repository: BDPA Publication year: 2022
Spectroscopic investigation on the effects of biochar and soluble phosphorus on grass clipping vermicomposting. Author(s): NOVOTNY, E. H.; BALIEIRO, F. de C.; AUCCAISE, R.; BENITES, V. de M.; COUTINHO, H. L. da C. Seeking to evaluate the hypothesis that biochar optimises the composting and vermicomposting processes as well as their product quality, we carried out field and greenhouse experiments. Four grass cli... ... Repository: BDPA Publication year: 2022
