2 øko-planter sviner mindre end én Organic Eprints
Kokkedal, Hanne.
Samdyrkning kan bruges til at reducere kvælstofudvaskning. På ESOF konferencen om uddannelser i København viste lektor Hanne L. Kristensen og Ph.D. studerende Yue Xie fra Institut for Fødevarer Aarhus Universitet hvorledes rødder fra porrer, blomkål og farvevajd vokser når de vokser hver for sig eller sammen i lange jordfyldte rør. Samdyrkning af fx. porre der har et overfladisk rodsystem med farvevajd der har et dybt rodsystem øger planternes evne til at optage kvælstof fra jorden og nedsætter dermed risikoen for kvælstofudvaskning end når porre vokser alene. Demonstrationen var en del af projektet InterVeg under CORE organic II programmet (GUDP).

Can new organic cropping systems produce vegetables with lower use of resources and losses of nitrate? Organic Eprints
Kristensen, Hanne L.; Xie, Yue; Bavec, F.; von Fragstein, Peter; Campanelli, Gabriele; Ortolani, Livia; Canali, Stefano.
To secure a sustainable production of plant foods for the future, there is a need to develop new cropping systems. These systems should have reduced needs of external resources and reduced environmental impact, while product yields are maintained at high level. Therefore, field trials were performed in Italy, Slovenia, Germany and Denmark with the aim to study new organic cropping systems for production of vegetable crops; and the systems’ effect on labor and energy consumption and the risk of losing nitrate to the water environment. The cropping systems included an in-season living mulch to exploit ecosystem services by attracting beneficial insects, suppressing weeds, and taking up excess nitrogen during production of two high-value crops of leek and...

Greenrelisient: Agroecological approch to organic greenhouse production in Europe Organic Eprints
Tittarelli, Fabio; Morra, Luigi; Testani, Elena; Ciaccia, Corrado.
All over Europe, organic greenhouse production systems are usually very intensive, which threatens their sustainability and the consumer trust. The implementation of less intensive production systems based on low energy consumption, appropriate crop rotations, use of agroecological service crops, and local organic inputs is possible at almost any latitude in Europe.

Nitrogen management in organic cauliflower Organic Eprints
Kristensen, Hanne L..
Consumers expect that the production of organic vegetables is less harmful to the environment compared to conventional vegetable cropping. However, vegetables with a high nitrogen demand such as cauliflower may cause intensive leaching of nitrate to natural waters in conventional as well as in organic production. In addition, organic growers face difficulties in providing adequate amounts of organic fertiliser in order to attain high yields due to the scarcity of organic livestock manure. In organic cropping systems, the use of an in-season living mulch may decrease the need for fertiliser and the risk of nitrate leaching. It may also improve nitrogen nutrition for next season’s crop. The aim of this study was to investigate the effect of growing an...
