containing pine bark, peat, and sand at a ratio of 3:1:1 produced less leachate NH 4 –N than a comparable substrate when peat was replaced with composted paper ( Cole and Newell, 1996 ). However, few studies have evaluated the leaching potential of composted
.35 to 0.90 dS⋅m −1 ( Fornes et al., 2010 ); however, this would raise concerns regarding nutrient-heavy runoff or leachate ( Flury et al., 2015 ; McPhillips et al., 2017 ). It is unknown if adequate leaching could be performed within a short timeframe
only partially attributed to plant water uptake, the changes resulting from irrigation and leachate had to be accounted for and omitted. Irrigation events, which are clearly indicated in Figure 2 by upward spikes, were excluded by a method adapted
application in a greenhouse. However, to the best of our knowledge, no study has evaluated the indaziflam in leachate samples as well as uptake by plants. Therefore, specific objectives of this study were to evaluate the leaching, degradation, uptake, and mass
perpendicular to the widest point were recorded for all plants and growth indices (height + average width) were determined. Additionally, the leachate resulting from pouring 100 mL of deionized water onto the surface of the substrate was collected, and EC and

surfaces. The design of the lysimeter facility was described previously ( Hay et al., 2007 ). Briefly, a 5-cm diameter polyvinyl chloride well screen pipe was placed at the bottom of lysimeters for leachate sampling and covered with 50 cm of packed silica
surface (constant water head). The amount of water applied to each column over the course of the leachate collection was three-times the volume of the column ( Ajwa and Trout, 2006 ). Chemical soil injection. A total volume of 0.3 mL solution of AITC

ice cubes were evenly distributed on the surface of the media. Ice cubes did contact aerial roots, but contact with leaves was avoided. Any leachate in the pots was poured out of the decorative pots 24 to 48 h after irrigation. Once a month, the
