Pre- and postharvest quality optimisation of organic vegetables that can stimulate an increased consumption
Organic vegetable production on stock less farms has a need of various off-farm nutrient resources. The parts of agricultural co-streams that not can be used as food or feed are relevant to be used as fertilizers for those needs. Our research within this project is related to utilization of anaerobic digested food waste, pulverized shrimp shell and alga meal in comparison with animal manure and mineral fertilizers. We have studied the nitrogen use efficiency, mineralization time, product yield, sensory quality and content of glucosinolates. Our studies was performed at two locations in Norway as a three year crop rotation with broccoli, potatoes and lettuce.
