There are approximately 2.3 million hectares of cropland in New York. Cultivated organic soils comprise about 12,000 hectares or 0.5% of the total cropped land. The organic soils are used exclusively for intensive vegetable production with onions being the primary crop. About 50% of these soils are located within the Lake Ontario drainage basin. A comprehensive field study was conducted to evaluate the yield response of onions across a broad range of N, P, and K fertilizer inputs and to correlate the level of response with soil testing parameters. A primary objective was to develop an estimate of P loss in drainage water to the Lake Ontario drainage basin and how this loss is influenced by P fertilizer management.
