What types of nutrients do CRF fertilizers contain?
Passchier: Most CRF nursery and greenhouse formulations contain the macro-nutrients: nitrogen, phosphorus and potassium. Several products contain the secondary nutrients: calcium, magnesium and sulfur; and often contain several micro-nutrients such as boron, copper, iron, manganese, molybdenum and zinc. Pilon: With CRFs, does the source of nitrogen matter? Passchier: I personally think that with CRFs, growers are looking for consistent results when growing their crops. I also believe growers want to use fertilizers as efficiently as possible. I use the phrase “maximum production with minimum input” when referring to how growers prefer to produce crops. There are two main efficiency factors that influence the nitrogen use of containerized crops. The first influencer is the crop itself and the production practices it is being grown with. Is it growing in such a healthy state that it can use the fertilizer that is there for its consumption? Does the porosity of the growing media allow ade
