Title
Fertilizer and Mulch Improves Yellow-Poplar Growth on Exposed harsells Subsoils
John K. Francis 1977
Other claims from this paper (7)
- Intervention effect Fertilizing and mulching increased height and diameter of yellow-poplars
- Intervention effect Topsoil removal without remedial treatment reduced yellow-poplar growth through four growing seasons
- Intervention effect Mulching did not improve yellow-poplar growth in the first year
- Intervention effect Fertilizer greatly increased yellow-poplar growth in the first year after application
- Intervention effect Growth on fertilized plots was about the same as on unfertilized mulched and undisturbed plots after the first year
- Intervention effect Fertilizer with mulch gave no added yellow-poplar growth
- Mechanism Mineral deficiencies and rapid drying apparently limit yellow-poplar growth on exposed subsoils, but physical structure does not
