Title:

Phosphorus Fertilization of Second Rotation Loblolly Pine Plantations (Forest Science Laboratory Productivity Group, Research Report No. 169)

Description:

The effectiveness of residual phosphorus (P) fertilizer from the first rotation to supply P to second rotation loblolly pine was investigated in two field trials. Both sites were poorly drained, clayey flatwoods sites inherently low in P, yet very productive when P­fertilized. In one study a first rotation P fertilization trial was harvested and the study site replanted to evaluate carryover benefits of residual P fertilizer. Phosphorus was also reapplied in this first study. The second study involved testing P rates and competition control in a second rotation plantation. In both studies tree growth was excellent when herbaceous weed control was used. However, phosphorus nutrition and tree volume growth were less than optimal when second rotation pines were not fertilized with phosphate. When stands were not refertilized but herbicides were used, tree volume was 72 to 96% of that obtainable with P applied at the beginning of the second rotation. To maximize gains from genetic improvement and competition control these sites should be refertilized with 40 lb/ac P by the beginning of the third growing season.
