Managing Surface Cover

1. Distribute residue evenly at harvest
2. Avoid fall tillage
3. Determine how your operations will affect residue cover
4. Estimate residue cover in the field
5. Adjust equipment to preserve residue
6. Plant a cover crop
7. Rotate crops
8. Select vigorous perennial pasture species
9. Protect the soil with special-use annual forage crops
10. Protect the soil with rotational grazing
11. Use no-till when renovating pasture
12. Manage timberland to protect soil

Controlling the Flow of Water

13. Reduce soil compaction and increase infiltration
14. Install grassed waterways
15. Plant vegetative filter strips or make critical area plantings
16. Farm on the contour
17. Use contour stripcropping and contour buffer strips
18. Install terraces
19. Install grade control structures
20. Install water and sediment control basin
21. Use diversions
22. Install a farm pond
23. Maintain your dtrainage system to protect surface water
24. Control streambank erosion with the willow-post method
25. Avoid channelization of streams and creeks

Managing Nutrients Effectively

26. Set realistic yield goals
27. Monitor the level of nutrients
28. Credit other nitrogen sources
29. Select nitrogen fertilizers wisely
30. Apply nitrogen in the spring
31. Apply fertilizer with a global positioning system

Managing Livestock Waste Effectively

32. Keep livestock out of water
33. Divert runoff water
34. Collect and store contaminated runoff
35. Install a vegetative filter - in appropriate
36. Determine accurate manure application equipment
37. Calibrate manure application equipment
38. Apply manure wisely

Reducing Insecticide Use

39. Scout fields for insects
40. Base decisions on the economic thresholds for insects
41. Use insect-resistant crop varieties
42. Use crop rotation and plant diversity to control insects
43. Spot-treat insect infestations when possible
44. Conserve beneficial insects

Reducing Herbicide Use

45. Scout for weeds and know their economic thresholds
46. Fine-tune your weed-control program to cut back on herbicides
47. Manage crops to compete aggressively with weeds
48. Don't assume that no-till requires more herbicide
49. Band herbicides and cultivate
50. Control weeds with cover crops

Selecting Pesticides

51. Select the leat-toxic pesticide
52. Determine your soil's potential for runoff
53. Determine your pesticide's potential for runoff
54. Determine the soil-pesticide interaction rating

Handling Pesticides Safely & Efficiently

55. Calibrate your sprayer
56. Consider direct injection and closed handling systems
57. Observe setback zones
58. Rinse and dispose of chemical containers safely
59. Dispose of excess chemical safely
60. Dispose of other farm waste safely

14. Install Grassed Waterways
	Grassed waterways control erosion and drain storm water safely off the land into designated outlets. They can also be used as outlets for the concentrated water coming from terraces, diversions, or adjacent properties. Grassed waterways are generally shaped in one of three ways: parabolic, trapezoidal, or triangular. Parabolic is usually the shape of choice because it is the shape found in natural watercourses and it is the easiest waterway to cross with farm equipment. Small flows of water are not as likely to meander in parabolic waterways, and contractors find them easy to visualize and build.
	Work closely with your soil conservationist at the Natural Resources Conservation Service. The minimum grassed waterway for small drainage areas is 30-feet wide and 1.2 feet deep.
	To protect the waterway from erosive water flow during grass establishment, the NRCS technician may recommend side diversions to keep the flow out of the channel. After grass is established, side diversions are removed so that runoff water flows into the waterway.
	Instead of side diversions, the technician may recommend rock or fabric checks to protect the waterway during grass establishment. Unlike side diversions, rock or fabric checks do not have to be removed. Rocks are normally placed in the center of a watercourse to a depth of 15 inches.
