    Can increasing soil carbon also increase soil CO2 back into atmosphere?

    Cellular life that dies in the soil is consumed by another so there might be short term spike in CO2, problem with soil ecology is that it is so complex. This happens with frozen soils, where some organisms are killed by freezing but as soon as there is a thaw they are broken down by other...

    Can increasing soil carbon also increase soil CO2 back into atmosphere?

    It's really interesting to note that any farming system that enhances soil carbon can increase Nitrous Oxide emissions which means that the benefit for reduced global warming is wiped out. Seems farming to increase Carbon isn't the silver bullet it's being touted as. Totally agree that...

    Can increasing soil carbon also increase soil CO2 back into atmosphere?

    Think you're right in that the OM/C you stick into the soil determines what you get back, totally cyclical. So by that logic if you stick more carbon into the soil it'll bung a bit more out. Think there will be a lag as a lot of OM isn't broken down so fast.....

    Can increasing soil carbon also increase soil CO2 back into atmosphere?

    I remember listening to a US soil scientist who thought that increased soil OM and subsequent increased soil microbe respiration increased the concentration of CO2 in the crop canopy and had the potential to boost yields. I'm thinking increased soil C isn't the answer to curbing atmospheric...

    Can increasing soil carbon also increase soil CO2 back into atmosphere?

    Of course increased soil OM/C leads to a better soil which will be more productive and has so much going for it, but selling C credits may be a step too far in many circumstances.

    Can increasing soil carbon also increase soil CO2 back into atmosphere?

    The concept of banking carbon got me intereested, as I thought that it was too simplistic to assume that just by increasing soil OM & C we reduce atmospheric CO2. There are a huge number of soil organisms and the more OM/C you send them the busier they get and the more active they are the more...

    Can increasing soil carbon also increase soil CO2 back into atmosphere?

    Finally decided to sit down and try and get my head around 'banking soil carbon' and the whole soil C sequestration thing. We are trying to increase soil organic matter (OM) levels for all the positive benefits that go with that - better soil structure, better drainage, better nutrient cycling...

    Switch to organic farming causes chaos in Sri Lanka

    Consuming far more than they need - creating waste and consuming more resources than are sustainably available. (Sustainable = consumption at a level that doesn't reduce future generations ability to also benefit eg. hunting something until it's extinct or polluting drinking water to such a...

    Wheat blend problem

    Was Rafaela, Valerie & Cassia. The first two have done well in the past so made sense to put them in. They all had at least one disease resistance trait that was better than the other 2 if that makes sense.

    Wheat blend problem

    I suppose the answer is I don't really know if it was the mix that contributed to an overall low incidence of disease - that could only be confirmed by replicated trial plots and controls etc. Having said that I did read around the idea which included some research papers and they were...

    Wheat blend problem

    Had the opposite experience in winter barley here this season. Grew a 3 variety mix, each variety with a different level of resistance but a similar ripening point. We used fungicides on one half of the field and none on the other. As far as we could tell there wasn't any difference in yield...

    It was given as an example of a 'reasonable precaution'......... it's obviously not reasonable where there is a growing crop.

    Autumn manure banned

    No they'll get away with it this year OK as: "no available storage for treated sludge from sewage plants treating domestic or urban waste waters (biosolids), supplied within a contract with the sludge producer, followed by unavoidable spreading on cropped land with an application that exceeds...

    Autumn manure banned

    Depends on the situation as to how much gets lost....... rainfall, slope angle, crop cover, drains, proximity to ditch/stream/river, high soil nutrient levels, soil damage, tramline directions........ When all of those are extreme then they come together as a polluting combination....... but...

    Autumn manure banned

    I think you're on the right tracks with that thinking. So if you had land low in P and K indices, could prove it wasn't at very high risk of run off or had much in the way of connectivity with ditches, streams, rivers then you could agronomically justify autumn applications on P and K grounds...
