Reply to Loss of Soil Carbon / Organic Matter
Julia and Brian, thank you for your responses.
I had not done the numbers that you put together Brian. They would definitely take some achieving and maintaining.
It is a relatively high biological input situation. We use compost and a lot of biological input through the irrigation. It is an orchard situation, so we have plenty of opportunity to…

Hey all,
Wondering if anyone has experience with foliars on forages in low moisture/drought conditions?
Looking to drive a bit of growth into autumn here in the UK
Any tips gratefully received, -

Hi Rowan, sampling variability (sample depth, in-field variability, etc) could be an issue, but if you are running a lot of samples and seeing consistent results then that doesn’t fully explain it. Another common culprit is switching soil labs but I’ll assume that’s not the case.
If I had to guess I would say at 0.4% OM increase per year what…

Hi Rowan, great job building soil organic matter over the years! my basic understanding is that carbon is a cycle, and if you’re measuring the humate form of carbon, it will go up and down according to plants & microbes cycling carbon like depositing/withdrawal (to put it in terms of a bank account). I don’t know the science of it well enough,…

Loss of Soil Carbon / Organic Matter
Over the past 10 years we have gradually built our soil organic matter up from around 1.9% to an average of 6%. The organic Carbon level rose from 1.1% to over 3%. We have seen gradual increases each year.
However over the last 12 months we have seen a drop back to 4% organic matter across all testing sights. This seems to be a massive drop…
