English Issue Biogas Journal | Spring_2021 The farmer Rolf Schneider has been farming his land with the no-till farming method for thirty years. His particularly focuses his crop management on improving the fertility of the soil. There is an abundance of earthworm castles like that in the arable land tilled with no-till farming methods. yield plenty of fresh matter, even as whole crop silage”. Sorghum, which worked well last year, or leguminous grain mixtures could be considered as drought stresstolerant fodder plants for possible successive crops. If the weather changes and a wet period is expected, Schneider says he could sow clover grass. The harvest in the fall is then followed by winter grain. Corn only grows in a two-crop system after vetch grown with rye or Landsberg mix is harvested while it is still green. Instead of corn, these crops can be followed by a summer crop as an alternative, such as a mixture of oats and peas. Current example: In late May this year, Schneider used the Amazone direct seeding machine to sow Landsberg mix on a 50-hectare field. After it was cut and taken to the silo, Schneider planted corn on the field over the next few days without cultivating the field any further. Stop destroying the dwellings of the diligent little helpers In a field of small young wheat plants, Schneider points to numerous mounds on ducts leading downwards, the so-called earthworm castles. “That’s were my most important workers operate,” he says. The earthworms are a true indicator of life as they work tirelessly to loosen and vent the earth beneath our feet and draw organic materials and thus nutrients into lower soil layers. “We should stop continually using applicator tools that destroy the dwellings of diligent little helpers like that, who reinforce the soil against adverse weather and make it fit for the climate change,” says Schneider. On his farm, Rolf Schneider breeds young cattle for a dairy farm. The dung and manure he gets from the heifers is fermented in the biogas plant and the digestate is applied to the fields as fertilizer to improve the soil. Author Dipl.-Journ.
