Conservation Tillage
•
Conservation-tillage farming:
method of soil
cultivation that leaves the previous year's crop
residue on fields before & after planting the
next crop
–
No-till:
involve planting crops directly into residue
that either hasn't been tilled at all
–
Minimum tillage:
some residue has been
removed, but at least 30 to 70% remains
No Till & Minimum Tillage
•
Planting into corn
residue (no till)
•
Soybeans grown in striped
rows between corn residue
(minimum tillage)
Benefits of Conservation Tillage
•
Environmental benefits
–
Reduces soil erosion by 60%-90% from rain &
wind
–
Improves
soil and water quality by adding organic
matter as crop residue decomposes
–
Conserves water by reducing
evaporation
–
Conserves energy due to fewer tractor trips
–
Reduces air pollution from dust and diesel
–
Crop residue provides food and cover for wildlife
Benefits of Conservation Tillage
•
Practical benefits
–
Fewer trips across the fields saves time and
money (lowers fuel, labor and machinery
maintenance costs) and reduces soil compaction
that can reduce yields
–
Optimizes soil moisture, enhancing crop growth in
dry periods or on droughty soils
Methods to reduce soil erosion and promote soil conservation include terracing, contour planting, strip cropping with cover crops, alley cropping, agroforestry, windbreaks, and conservation tillage practices such as no-till and minimum tillage. These methods help in minimizing soil erosion hotspots and offer environmental benefits like reducing erosion, improving soil quality, conserving water, and providing cover for wildlife. Additionally, conservation tillage provides practical benefits like saving time and money, reducing soil compaction, and optimizing soil moisture for enhanced crop growth.
