Since all mixes contain small and large-seeded species, a maximum sowing depth of 2 – 3 cm is
recommended. When preparing the seedbed, it is important to take into account the requirements of
the fine seed (friable, well reconsolidated seedbed). To conserve water and suppress competition
from volunteer cereals and oilseed rape, sow the seed immediately after harvesting using shallow
tools. A combination of tillage and drilling (e.g. with a mulch seed drill) is ideal. If adverse
weather conditions or availability of labour prevent rapid drilling, suitable soil cultivation
measures must be undertaken to prevent volunteer cereals gaining the upper hand. Particular care
must be taken with the swath zone following successful straw harvest. Rollers used in combination
with spreading and drilling equipment can be very effective. It is important to make sure that the
straw is well distributed. It is advisable to apply a dose of nitrogen if there are large
quantities of straw. Sowing rates are calculated on the basis of a well-prepared seedbed and
optimal sowing times and should be closely followed to allow for differences in the competitive
behaviour of individual components in the mix. Sowing rates should be increased only in the event
of adverse external conditions such as poor seedbed, delayed sowing time, poor nutrient supply or
® mixes contain a high proportion of leguminous plants, basic nutrients can be supplied
largely through farm yard manure (FYM) prior to sowing. Nitrogen is then provided by the relatively
high proportion of legumes. In the absence of FYM, the addition of 30 – 40 kg/ha N and for straw
manuring 40 – 50 kg/ha N may be of benefit, depending on the previous-crop. The maximum permissible
rate of FYM can be applied to the BioMax DT to ensure an adequate nutrient supply. In the absence
of FYM, 50 – 70 kg/ha N without and 60 – 80 kg/ha N with straw manuring is recommended for max.
growth (no N after leguminous pre-crop).
General cultivation tips:
If sown too early and under stress conditions (especially drought stress), premature seed
formation may occur with some plant species (buckwheat, mustard, oil radish, phacelia). In such
cases it is advisable to check growth in good time by chemical or mechanical means to prevent seeds
The growth should definitely not be incorporated when green.
If the mix shows a lot of leafy growth in the autumn, plants should be chopped back and
mulched. If growth is still green come spring, plants should be treated with herbicide. Under no
circumstances should green material be incorporated in the soil.
