Agroøkologiske principper til tomater Organic Eprints
Petersen, Karen Koefoed.
I projektet GreenResilient er det målet at demonstrere, at med en agroøkologisk tilgang til dyrkning af økologiske væksthusgrøntsager opnås mere robuste dyrkningssystemer, når de tilpasses lokale klimaforhold.

Stepwise incorporation of white clover (Trifolium repens L.)as fertiliser increases nitrogen fixation and improves nitrogen retention when intercropped with leek (Allium porrum L.) Organic Eprints
Xie, Yue; Sørensen, Jørn Nygaard; Petersen, Karen Koefoed; Kristensen, Hanne Lakkenborg.
Background and aims We investigated whether the incorporation of intercropped white clover as a split-dose fertiliser improves N retention of the plant-soil system in leek production. Methods White clover and leek were grown in pots where clover was stepwise incorporated into soil as fertiliser. Half of the clover was incorporated before leek transplantation (LT), the other half was incorporated 26 (S1) or 41 (S2) days after LT, compared with full incorporation of all clover (F) before LT. 15N injection and leaching studies were performed to investigate interspecific competition and the effects of precipitation on soil N availability. Results Stepwise incorporations increased or had no effect on leek growth, despite competition for N between white...
