Abstract:
A two year experiment with base fertilizer and re-using of peat was carried out.
No significant effect of base fertilizer was found using a complete nutrient solution, but there was probably a positive effect of only liming.
No negative effect was found, from the reuse of peat bags using peat bags twice, irrespective of earlier base fertilizer.
Peat bags may be used twice when no pathogens are noticed on the roots.
