Abstract
Fertilizing and mulching of eroded Hartsells soil increased height and diameter of yellowpoplars. To see if chemical infertility of exposed Hartsells subsoils limits yellow-poplar growth and to test fertilizer and mulch as remedial agents, seedlings were planted on undisturbed soil, soil with the topsoil removed, and soil with the topsoil removed but mulched with leaf litter. After one growing season, 9 of the 18 plots were fertilized. Topsoil removal with no remedial treatment reduced growth through four growing seasons. Mulching did not improve growth the first year but did in subsequent years. The first year after application, fertilizer greatly increased growth: thereafter growth on fertilized plots was about the same as growth on unfertilized mulched and undisturbed plots. Fertilizer with mulch provided no added growth. Mineral deficiencies and rapid drying apparently limit growth on exposed subsoils, but physical structure does not. Additional
