Title: Effects of Fertilizer Nitrogen on Tree Growth, Foliar Nitrogen, and Herbage in Eastern Cottonwood Plantations

Author: Blackmon, B. G.;

Date: 1977

Source: Soil Science Society of America Journal 41(5):992-995

Publication Series: Scientific Journal (JRNL)

Description: When five rates of nitrogen fertilizer (0 to 672 kg/ha) were tested in two eastern cottonwood (Populus deltoides Bartr.) plantations 7 and 10 years old in the Mississippi River floodplain , first season volume growth was more than doubled by fertilization . By the end of the third season, the direct effect of fertilization had apparently disappeared although a volume advantage caused by the large initial response was still evident. In one plantation, volume growth for the 3 years after fertilization was greatest at 336 kg Nt ha , and in the other volume growth was greatest at 672 kg NI ha. However, lower rates gave more volume growth per unit of applied N. Fertilizer also increased the N content of herbaceous plants.
