The method followed has been as a rule the following. The rough moor is drained down to ! 2 / 3 m. Under the original surface. Then the vegeta- tion is burnt off, the largest tufts are cut down and all is levelled with the earth from the ditches. After adding 500 to 100 kg. Of CaO per hec- tare the ground is left untouched for 1 to 2 years. Then a layer of clay 2. 5 4 cm. Thick is added; further about 36 m. 3 of clay marl (with 25 to 30 / chalk) per hectare, which corresponds to 6000 to 9000 kg.... CaO per hectare. After this (in the month of March) 180 kg. Of 37 / potash manure and 270 kg. Phosphates are added, for meadow; smaller quantities for pasture. Nitrogenous manure is not given, but in general a compost is added. The moor is afterwards worked over with the disc-harrow (March April) and a light harrow. In the same year experiments are made with Leguminosae (peas and vetches). The disc-harrow is used again in the autumn and following spring. This year the ground is laid out for grass: grass and clover seed (with a covering crop, in general oats) covered with the light harrow; the ground is rolled.
