leachates, teas, and other extracts are produced by the activity of earthworms from a wide range of organic wastes ( Gutiérrez-Miceli et al., 2008 ; Ievinsh, 2011 ; Padmavathiamma et al., 2008 ; Wang et al., 2010 ). They are products of non

volume of water leached per plant increased with increasing NaCl in the irrigation water because the plants could be salt stressed, and thus had higher leaching rates ( Table 1 ). Leachate volumes per plant were 1.6 and 2.2 times higher in T 2 and T 3

methods, but the first was planted in the summer and the second in the spring. Due to much higher leachate volumes for FAB in the first experiment, we adjusted FAB irrigation in the second experiment with the goal of achieving similar leachate volumes as

effect of irrigation water chemistry on C, N, and P released to leachate. We hypothesized that in a managed urban system, different vegetation types would influence DOC and DON leaching and that irrigation water chemistry would contribute to differences

Potential exists for reduced water use and improved water quality in container nurseries through redesign of the container to minimize leaching. `Celebrate' poinsettias were grown in trade gallon containers with modified drainage hole number and size. Irrigation was applied when an individual container's medium decreased to 80% of container capacity; a gravimetric method was used to determine daily water requirements. Containers with one drainage hole in the center bottom reduced applied water (13%) and leachate volume (90%) compared to standard nursery containers (4 drainage holes in the side and one in the center bottom). Plant quality was similar with these treatments.

. Second, as a result of irrigation in amenity landscapes with various plant forms, amounts of leachate were measured in each plant combination. Water percolating downward and potentially recharging groundwater in amenity landscapes has not been measured in
