The Effect of Soil Fumigation on the Growth and Yield of Loblolly Pine Seedlings in the Nursery
The production of pine seedlings is expensive and exacting. The gross cost of nursery stock may be several thousand dollars per acre; few, if any, crops are more soil depleting or require more careful soil management practices. These factors, together with increased demands for more and better seedlings, are of much concern to those charged with the responsibility of seedling production and nursery management. In general, a unit of nursery soil tends to produce a constant weight of seedling tissue in the form of either many small seedlings or fewer large ones; therefore, any practice that will insure a maximum production of plantable seedlings is of considerable importance. The purpose of this study was to test the general hypothesis that more plantable loblolly pine seedlings of better quality could be grown on a given unit of nursery soil through soil fumigation for the control of plant parasitic nematodes. Nematodes are microscopic eelworms, many of which feed on the roots of plants. They may be the underlying cause of puzzling ailments in certain nurseries.
