THE USE OF BARKCOMPOST IN FLORICULTURE IN SPECIAL CONSIDERATION OF NITROGEN NUTRITION |
| Author: | H.-D. Molitor |
| Abstract:
Results of incubation experiments with barkcomposts under different conditions are reported. Barkcompost without or with low N-addition before composting shows a considerable decrease in mineral-N content during incubation; NH4-N was immobilized much faster than mineral-N in the nitrate form. Plant experiments with Euphorbia pulcherrima show a normal plant growth when additional nitrogen was added. Decrease in mineral-N content during incubation was low in barkcompost with sufficient N-addition before composting. After a short period of immobilization a considerable increase in mineral-N content due to mineralization followed. | |
