| Four months after application of sheet steaming to the soil in an organic greenhouse, the treatment had still a significant effect on the diversity of the soil microflora (bacterial and fungal populations). Also four months after steaming, two fertilizer types differed significantly in their effect on microbial composition. Goat manure had a positive effect on bacterial diversity, while spent mushroom compost had a stimulating effect on fungal diversity. |

| An on-farm field trial was set up in an organic greenhouse in order to balance the N-uptake by a sweet pepper crop and the mineralization of the organic fertilizers was applied. The effects of six fertilizer treatments were compared regarding yield, nutrient availability and mineral balance. Application of high levels of compost turned out to be favourable in order to reduce surplusses of available-N on the short term. On the long term, such high levels of compost are unfavourable as a high pool of mineralizable-N in the soil organic matter restricts the possiblities for precise fertilization adapted to plant uptake. Application of lower levels of farm yard manure in combination with additional fertilization with feathermeal turned out to be a good... |
