Abstract: Many greenhouse managers do not fully comprehend the
relationship between crop fertility and ground water pollution, and
impacts of fertility on pest & disease. Better management of fertilization
improves crop quality and reduces nutrients lost to the ground(water).
We tested pH and soluble salts weekly during the Poinsettia growing
season, and sent off soil and foliar samples to Peters for lab analysis.
In general, the growers highly valued the project because cultural errors
were caught early. Several of them will continue the monitoring in the
future; the others would like a professional to do it for them. We need
to extend understanding of the importance of monitoring nutrient solutions
to other greenhouse operations, and also to revise the Poinsettia crop
production guide for New York.
