Benefits of Leaving Crop Residue
• Reduces soil compaction
• May reduce weed problems
• Reduces erosion by wind and water
• Reduces nutrient and pesticide run off
• Builds soil organic matter
• Conserves soil moisture
• Limits release of carbon to atmosphere
(a contributor to global warming)
• Provides food and shelter for wildlife
• Conserves fuel, labor and time
Suggestions for Residue Management
• Mow cotton stalks with a fl ail-type mower,
leaving stalks about six inches high.
• Cut small grains high so more residue is
left standing than is left on the ground.
• Use a straw chopper and spreader on the
combine to minimize windrowing.
• Mow or bale straw from any windrows.
• Use sharpened, notched coulters that cut
through residues more easily.
• Attach a residue manager to the planter to
clean crop residues from the row.
• Increase pressure on coulters by tightening
tension springs and adding weight to
planter.
• Plant after dew has dried on crop residues.
• Plant at an angle to the row pattern of the
previous crop.
Hazards of Burning
• Depletes soil nutrients like nitrogen
• Leaves soil surface exposed to erosion
• Presents fi re and smoke hazard/nuisance
• Poses a health hazard, especially for
children, the elderly, and people with
health problems
• Contributes to air pollution
• Adversely affects soil structure
Do Not Burn Crop Residue if
• Animal waste has been applied to the fi eld
• Crop residue is included in an erosion
control or water quality plan
• Prevailing winds will carry smoke to
roads, homes, or businesses
• It is evening (between 6 p.m. and 8 a.m.)
• Occupied buildings are within 1000 feet
• You have not checked with representatives
from NCDENR Division of Forest
Resources and county authorities about
local restrictions and the need for permits.

Allowing crop stubble and residue to provide soil cover is much more environmentally and
agronomically sound than plowing or burning.
