Bud Failure of Green Ash The influence of tree nitrogen (N) status in autumn on bud necrosis the following spring was evaluated using green ash trees grown with N from either urea formaldehyde (UF) or a controlled release fertilizer (CRF). Scagel et
. Fertilizer application rate. At the time of transplant, we incorporated 7 lb/yard 3 of 15N–3.9P–10K controlled-release fertilizer [CRF (Osmocote Plus ® 15–9–12, 5- to 6-month longevity; Everris)], which served as the low fertilizer application rate. An
( Ogden et al., 1987 ). Controlled-release fertilizers (CRFs) have been very effective in supplying plant nutrient needs and minimizing the loss of environmentally problematic ions such as nitrate nitrogen (NO 3 -N) and phosphate phosphorus (PO 4 -P
turfgrass “quality” to greenness on a visual scale of 1 (yellow or brown) to 9 (dark green). Controlled-release fertilizer (CRF) and slow-release fertilizer (SRF) often have been used interchangeably, unless specifically defined by the author. Turfgrass
and March and were air-dried and screened through 2-mm mesh. Care was taken during soil sampling to avoid the bands of controlled-release fertilizer (CRF) applied by most growers below the plant row before plant establishment. Soil pH was determined
different management practices: 1) standard tree density with controlled-release fertilizer (CRF) and microsprinkler irrigation (STD_dry_MS); 2) high-density staggered planting with fertigation and microsprinkler irrigation (HDS_fert_MS); and 3) high
, they concluded that varieties from Oregon exhibited good performance, but did not show improvement over traditional Mediterranean varieties. New Fertilizer Coatings/Blends for Nursery Crops Controlled-release fertilizers (CRF) continue to be a valued

-production nutrition in the retail environment for consumers. The controlled-release fertilizer (CRF) (i.e., Osmocote ® , 14N–4.2P–11.6K) formulation produced marketable plants in our study (although not the largest plants). Oxalis has a short-term production schedule
). Four containers of each treatment were randomly selected and harvested 4 and 8 weeks after potting (WAP). Substrates were harvested by first scraping the top 1.5 cm of substrate away and thereby removing all controlled-released fertilizer (CRF) prills
