[QUOTE="Simon C, post: 7382545, member: 319"] Nice to have a bit more detail in this test result but what is missing in the actual weight of carbon per hectare. It can be worked out from the % C and the bulk density but then only tells you how much in the top 30 cm. There is a heck of a lot of C down there deeper than that. Trouble then is you want to do annual tests to monitor increases but wandering around a field in a W pattern collecting samples is never going to accurately represent an average for the field each year. How many samples would it need to to get a proper representation of even one hectare, 50, 500, 1000? Interesting that all fields are near as dammit C:N 10, which is what what we always work on.
