Effect meerjarige toepassing groenbemester en organische mest op bodemkwaliteit bij continuteelt maïs : 2e rapport project Zorg voor Zand Organic Eprints
van Schooten, H.A.; van Eekeren, N.; Hanegraaf, M.C.; van der Burgt, G.J.; de Visser, M..
In 2005 is onderzoek gedaan naar het effect van meerjarige toepassing van groenbemester en organische bemesting op diverse bodemkwaliteitskenmerken bij continuteelt van snijmaïs op zandgrond. De conclusie is dat het effect op de bodemkwaliteit en gewasopbrengst van organische bemesting wat groter was dan van groenbemester. De biologische activiteit werd nauwelijks beïnvloed door beide behandelingen.

The Inner Quality Concept for food, based on life processes Organic Eprints
Bloksma, J.; Huber, M.; Northolt, M.; van der Burgt, G.J.; Adriaansen-Tennekens, R..
How can we adequately express the quality of food produced by organic agriculture? To answer this research question, we defined a concept of ‘inner quality’ (formerly called ‘vital quality’) based on the life processes growth and differentiation, and their integration. Growers use management methods to influence life processes in their crops, thus optimising the quality of the final product. Traders and consumers can recognise certain product properties as being the result of these life processes. Here, we present a course of validation for the quality concept, together with appropriate quality parameters. The process of validation has been completed in part for two experimental crops, apple and carrot. This quality concept can provide a holistic context...

NDICEA nitrogen planner Organic Eprints
van der Burgt, G.J..
The program NDICEA nitrogen planner presents an integrated assessment on the question of nitrogen availability for your crops. This is more than a simple nitrogen budgeting for each crop: crop demand on one side, and expected availability out of artificial fertilizers and manures, crop residues, green manures and soil on the other side.
