The > reverse is true, XXXXXXXXXXXXXXXX Hi Chi,Check out Dr. Elaine Ingham's website at www.soilfoodweb.com. Lots of things could cause compaction of farmland and various soil types would compact differently independent of organic matter content. Lack of earthworms would compact and of course they'll die without whatever they need for survival.There's even people selling earthworms for farmers apparently using no-till methods and a type of strip cropping.Dennis Kemnitz compaction of soil is due to low soil fertility. > Neither are anerobic microbes a cause of low soil fertility nor > aerobic microbes a cause of high soil fertility, both are the result > of either low soil fertility or high soil fertility.

XXXXXXXXXXXAs It's not quite that simple, is it? The soil food web probably is nearly non-existent on " low fertility soil " although it would depend on exactly what is causing this " low fertility soil " . You probably have defined these terms(hi and low fertility) previously. As of now we're doing a lot of generalizing cause I don't know your def'n.. High fertility soil has bio diversity (based on studies on unplowed grasslands and forests)that includes 25,000 bacterial species per spoonful. The anaerobes produce acids, and volatliize N and S and probably other elements and therefore lower ph which kills the plants roots causing compaction. This in my opinion makes it " low fertility soil " .Dennis Kemnitz That is good for the microbe sellers. XXXXXXXXXXXXxProperly made compost is full of microbes, fungi and protozoa and maybe beneficial nematodes as well. 25,000 species of bacteria per spoonful in productive soil is the goal.And there are specs for fungi too.I use compost which ultimately makes nitrate and ammonium available for the plants to use in a timely manner. Dennis Improve your soil > fertility XXXXXXXXXXBased on Albrecht's def'n? Dennis and you will have no need to add aerobic microbes, they > will just show up on their own. > XXXXXXXXXMaybe, but I don't think so, on these toxic chemical farms of the last 55 years w/o the addition of properly made (and tested compost). That ground is essentially sterile (and compacted)so can the aerobes get into the soil 10 feet down and live a RADIANT life? Some of those 25,000 aerobes will begin detoxification of the toxic chemicals added the last 55 years. There are a lot more organisms than live microbes in productive soil.
