PlantyOrganic: Results 2013 Organic Eprints
Hospers-Brands, A.J.T.M.; Anema, D.; Bus, M.C..
2013 was the second year of the "PlantyOrganic" system development in practice. The six-year rotation is laid out and measurements took place at soil and crop. With the exception of the potatoes in 2013 all crops had the pre-crop as foreseen in the design. The fertilizers used were completely produced in the own system, as foreseen in the system design. The amounts of nitrogen applied were about 45 % higher than in the design. Soil nitrogen is measured and used as input in the nitrogen model NDICEA. There was a sufficient match between measured and calculated level of soil mineral nitrogen. The crops performed well, with a high yield in carrots and oats, and a disappointing yield in wheat. In wheat nitrogen was limiting for the yield, we do not yet have a...

PlantyOrganic; Voortgang 2013 Organic Eprints
Hospers-Brands, A.J.T.M.; Anema, D.; Bus, Michiel.
2013 was het tweede jaar waarin de systeemontwikkeling "PlantyOrganic" in praktijk is gebracht. Op de zes percelen zijn de gewassen geteeld die voorzien waren en zijn metingen verricht aan bodem en gewas. Met uitzondering van de aardappelen hadden in 2013 alle gewassen de voorvrucht die in het ontwerp was voorzien. De gebruikte meststoffen waren geheel afkomstig vanuit het eigen systeem, zoals in het ontwerp was voorzien. De totaal gegeven hoeveelheden stikstof waren ca. 45 % hoger dan waar in het ontwerp van uit is gegaan. De bodemstikstof is getoetst met metingen die in het stikstofmodel NDICEA zijn ingevoerd. De match tussen metingen en berekeningen is voldoende tot goed, met een enkele uitzondering. De gewassen groeiden goed, met hoge opbrengsten in de...
