|The field sampling campaign in 2015: from morning haze to late night!|
Soil microbial samples were collected, and soil DNA was already extracted from 2015 samples, and is currently in a process of sequences analysis. In addition we measured soil CO2, CH4 and N2O fluxes in autumn 2015, using a closed dynamic chamber method. Preliminary analyses shows no significant effect of biochars on above mentioned gas fluxes.
In addition to above study, Mr. Jure Zrim has recently started working on effect of recycled organic fertilizers (including BC) on soil properties, crop growth and microbial community structures in (Tila)Hykerrys project, where four new experimental sites have been established since June 2016.
