In an operating mode of shrinking resources and expanding clientele, the Cooperative Extension System is continually asked to do more with fewer funds ( Lyons et al., 2008 ), and the Master Gardener training program directly experiences these budget

Recent legislation in North America suggests stricter control will soon be put on the release of nitrogen and P-laden greenhouse wastewater into the environment ( OGVG, 2012 ). Unlike nitrogen, conventional treatment systems for greenhouse

Small-scale research plots and demonstrations of fertilizer application through a drip-irrigation system have inherent characteristics that make using commercial fertilizer injection systems difficult. Uniform fertilizer application, without excessive water, is essential for meaningful results in these small-scale, rate-specific studies. An inexpensive, easy to build, continuously diluting fertilizer injector is described. This injection system was reliable and provided uniform application under the confines of a low flow rate.
