摘要

German farmers have been down the min till route for some years. The benefits of reduced autumn tillage to make best use of scarce labour, speed up post-harvest operations and, hopefully, reduce seedbed preparation costs by up to 40 pound/ha have been seized by family farms of 400ha and more. In some German states growers also receive 100 pound/ha to adopt this anti-erosion cultivation tactic. Frank Semsrott has seven years with min till in Mecklenburg under his belt and credits it for improving soil fertility and structure ruined under communist management. Liming his grade 2 and 3 land brought the pH back up, but regular subsoiling and straw incorporation restored life to the soil and doubled winter wheat yields to 8t/ha. An 8-blade Paraplow wasused to breakup the plough pan hampering root development, and min-till techniques adopted to deal with straw and conserve moisture, as well as build a soil structure to deal with dry summers. He has recently gone down the Kockerling route with a systemthat includes an AT450 airseeder and a 4.7m precision cultivator from the German min till equipment specialist. On his sandy to sandy loam soils, he tries to use the cultivator twice behind an ageing Russian, 220hp K700 tractor to distribute straw before drilling. If there isn't time, or it is wet, he has an 18m Kockerling harrow to shift the straw. He estimates his cultivation costs are much the same as ploughing because of the two passes, Paraplowing every three years, and subsoiling all the tramlines. However, Dieter Horsthemke, Kockerling general manager, says some growers claim typical savings up to 40 pound/ha. Timeliness is important; he now drills 40-50ha of oilseed rape in a day. Like many German farmers, he uses a combine chaser trailer to load drills and spreaders. Direct drilling is possible with the AT450, which spreads the seed evenly across the field, provided the straw level is low. Using a previous disc seeder, Mr Semsrott found the disc pushed straw into the slots and the rapeseed rotted on the straw.
