Controlled Release Fertilizer Improves Quality of Container Longleaf Pine Seedlings

In an operational trial, increasing the amount of nitrogen (N) applied to container longleaf pine seedlings by incorporating controlled release fertilizer (CRF) into the media improved seedling growth and quality. Compared with control seedlings that received 40 mg N, seedlings receiving 66 mg N through CRF supplemented with liquid fertilizer had needles that were 4 in (10 cm) longer as well as...

A Three-year Study of Immersing Stored Loblolly Pine Seedlings in Water before Planting

Survival of loblollypine seedlings stored in unheated buildings from four to nine weeks improved five to eight percentage points when they were immersed in water for an hour before planting. Soaking for a day gave essentially the same results, but soaking for one or two weeks reduced survival drastically. Brief immersion of s~edling packages every two weeks during storage impro~ed survival four...

Ponderosa Pine Seedlings and Competing Vegetation: Ecology, Growth, and Cost

Foresten oftm need information on the cost effedivenessofmanual and chemical release treatments for individual and combined species in young mixed-shrub communities. A studvin northern Califomia evaluated fivemanual and chemical treatmcnts and their effect an several shmbs and grasses. Treatments were grubbing at age 1 to 2-and 441 (0.6-and 1.2-m) radii, regrubbing and expanding the 2-ft radii ...

Growth and nutritional response of hardwood seedlings to controlled-release fertilization at outplanting

Hardwood bareroot seedlings typically undergo transplant shock immediately following afforestation planting associated with moisture or nutrient stress. Broadcast field fertilization at outplanting with readily available nutrients has shown limited capacity to reduce nutrient stresses. Furthermore, the rapid nutrient release characteristic of broadcast fertilization leads to high levels of nutr...

Mineral nutrition and growth of containerized Pinus halepensis seedlings under controlled-release fertilizer

Low, moderate and high rates (3, 5 and 7 g/l, respectively) of two controlled-release fertilizer (CRF) types, Osmocote 9–13–18 and Osmocote 17–10–10 were evaluated for their effects on production of containerized Pinus halepensis planting stock. Both formulations had similar patterns of nutrient release, with high release rates during the first 2–3 months, in contrast with minimum seedling upta...
