Both microbial biomass and respiration are parameters used to assess soil health. Soil respiration is the measure of the carbon dioxide produced by the microbes in a given weight of soil while microbial biomass is the measure of the mass of microbes- both active and dormant. Microbial biomass (MB) is
Adam Jone’s Fig Tree Organic Farm in Queensland, Australia has moved to organic farming. This farm is one of the key producers of foods for the Organic Weekend Sunshine Coast markets, a famous destination for food consumers and tourists. Adam had spent a lot of his time trying a variety
The Biospheres, working through the CDA*, accompanies and trains farmers/agricultural companies in the agroecological transition based on a soil conservation approach. The group is also working on applied research projects and therefore on trials under real farming conditions in which they evaluate the impact of certain changes in practices on
Jeff Lowenfels, a valued advisor and member of our Board, was recently featured in the New York Times Sunday Magazine article, He Wrote a gardening column: He ended up documenting climate change. For 45 years Jeff has written a gardening column for the Anchorage Daily News and over this time
Modern agriculture practices have led to the systematic degradation of the world’s soil and release of carbon into the environment. The effects are increased need for expensive and environmentally dangerous inputs (fertilizers, pesticides, and herbicides), the loss of fertile top soil, decrease in water holding capacity of soil and dangerously
Soil carbon is important to soil health because it enables microbial life. Microbes are able to obtain carbon directly from plant exudates, however, much of their carbon source is from the dead plant and plant derived materials that they digest. We harvest much of the above ground matter from crops, but
The microbial population or microbial biomass (MB) reflects soil fertility. For over 2 million years, plants and soil microbes have worked together to create what we call fertile “soil”. How do they work together? The plant supplies the microbes with carbon rich food. The microbes then mine the soil for
Increasing your soil microbes increases carbon sequestration. Carbon is stored in the soil as “humic materials” i.e. C,N,P,K etc.; rich organic matter which is the soil organic carbon or sequestered carbon in the soil. The formation of humus, the final stable carbon, is a stepwise process. All organic carbon
Sítio Escola Portão Grande hosted students from the Mentoring and Language Acquisition Program (MLAB) for a full day immersion at the farm in Brazil which featured soil testing with microBIOMETER®. MLAB is a mentoring and language acquisition program for Harvard students and Brazilian high school students, with low income and
