| Summary: | after one growing season for the aforementioned plus tissue already in place. Manipulation of seedlings by fine- compartment 4 and 7a showed that 7a seedlings had higher compartment 7a.The results of this study indicate that concentrations of N, P, Y, Ca, and Mg. concentrations, P foliar concentrations, and K stem and dress magnesium. Nitrogen was supplied as ammonium effects of constant versus increasing applications of effort was made to evaluate the influence of different fertilizer was included in this study. In addition, an for shoot length, root length, and stem diameter, and again higher K stem and Mg root concentrations. Applications higher N concentrations in foliage and stem tissue. higher needle to stem and needle to root weight, and Increasing applications of N resulted in significantly inns taeda L.) seedlings. Morphological traits as well as K. Comparison between top-dress applications of N in minor changes in nursery practices that are currently moisture management, result in optimum seedling growth. N had no effect on the seedlings except for mean needle:stem weight. Top-dress applications of Mg had no nitrate(NH,N03) and magnesium as magnesium nutritional status were measured. A comparison of the of N in compartment 7a increased mean needle weight, N one growing season showed that pre-plant applications of over the short growing period. Sampling performed after probably due to heavier soil that caused loss of roots production of quality seedlings can be enhanced through rate significantly increased concentrations of N, Mg, and ratios were increased.
