Hello,
My current job is to study soil aggregates and soil microorganisms. I want to extract DNA from individual aggregates and measure some soil physical and chemical properties, such as soil carbon and nitrogen. Our aggregates range in mass from 100 to 300 mg, but DNA extraction takes up a large part of its quality. I want to know what methods can be used to measure soil carbon and nitrogen with small-mass soil samples in individual aggregates.
Thank you in advance.
