Seed and fertilizer

Real Direct Seeding

Traditional seeding method

Modern slowly soluble granular fertilizers are well suited for placing in the same furrow as the seed.
Understanding of the burn effect of fertilizer dates back to the ´50s when the fertilizers were powdery and quickly soluble. The nutrient content was low, so the amounts required were large. At the time, the contents were 6-6-7 N-P-K.

Nowadays we use compound fertilizers with a high nutrient content and precisely mixed proportions. Therefore, we do not have to use as much fertilizers as earlier. The practical experience of several years has not shown any adverse effects. On the contrary, it has been established that, as the fertilizer is in the same furrow as the seed, the plant is able to make better use of the fertilizer. This has made it possible to reduce the fertiliser amount, in particular for organic soils.

On seeds with hull, such as oats and barley, no burn effect caused by fertilizer has been established.
On sprouting of hulled seeds, such as wheat and turnip rape, it may have some effect.
The effect may be alleviated by increasing the amount of seeds: increasing wheat seed by about 10-20% and sowing 10-12 kg/ha turnip rape instead of 8 kilos.

The sprouting may be less intensive in Real Direct Seeding. This does, however, not affect the yield as the number of shoots may be bigger and the plant grows a longer ear and heavier grains. The protein content of malt barley is established to be about one percent lower with direct seeding than with traditional farming and, therefore, the malt barley is more marketable.
