Intermountain Forest Tree Nutrition Cooperative (IFTNC) Klickitat Re-fertilization Progress Report Item Info

In the fall of 1990, the IFTNC established six fertilization study trials in the Klickitat area of south central Washington. Three IFTNC members were involved in the establishment ofthese study trails. Cooperative members include: Champion Timberlands, Longview Fibre and Washington Dept. ofNatural Resources. The original fertilization trails were designed to study the effects ofnitrogen (N) and potassium (1K) fertilization on tree growth and survival. Tree fertilization response (basal area and cubic volume response over that ofthe controls) was monitored every two years and response results were summarized. Six-year results showed that periodic volume growth response for each two-year period since fertilization gradually decreased over time. However, significant responses were seen on individual sites by parent material types. Examination ofthe six-year results and re-evaluation oftree nutritional needs in this area prompted the cooperators to further investigate fertilization response in the Klickitat area with a refertilization of the existing 1990 installations.
