1 TURN THE PAGE FARMING NON-HERBICIDE NOTILL FARMING METHOD 1. No-till farming without herbicides 2. Potential for organic farming systems 3. Not currently used for large scale production 4. 3rd Weed Science Class demo in Fall 2015

crop cycle Requires site prep involving also: 1. Plow down currents weeds and crop remnants, 2.

2 Weed control in vegetable crops Has always been challenging Herbicide choices are limited Post harvest weed destruction requires plow down and disking during busy times Cover crop b/w cash crop cycle Requires site prep involving also: 1. Plow down currents weeds and crop remnants, 2. Seedbed preparation, seed placement & coverage 3. Cover crop growth 4. Plow CC as prep for crop cycle

3 Incomplete weed plow down perpetuates the problem, too much disking leads to soil compaction and increased soil erosion potential

4 An alternative approach to vegetable crop pre-plant soil preparation 1. Requires a significant change in farming concepts 2. Requires the use of woven black plastic mulch on a commercial scale 3. Opportunity to develop hydro seeding for crop establishment 4. Allows for no-till planting of cover crops and cash crops 5. Allow for no-till destruction of post harvest crop residue and weeds Referred to as Turn the Page Farming

6 Large scale use of woven weed mat For Commercial scale vegetable production 1. Use long sheets of woven black plastic fabric to cover soil and kill weeds 2. Secure the one side in trench other side to water filled hoses 3. Flip sheet to kill weeds and cover crops and expose new weed free planting surface 4. Hold mat down with water filled lay flat hose, avoids using pins that make holes = reduced useful life of fabric

9 Extending the wiggle wire beyond the clip base results in puncture holes

10 Mature weeds covered and killed Plant tissue break down rapidly Surface weed seeds grow and die Minimize soil disturbance when planting. Subsurface soil has lots of weed seeds.

11 0-day 7-day 14-day 14 days of weed growth

12 21 days of weed growth 0-day Cover 1-wks 14-day 7-day

13 Good weed kill w/ 1-week of cover 14 days of weed growth 14 days weed growth + 1-wk cover 3-wks weed growth

14 With small annual weeds or short term cover crops 1-2 weeks of cover provide weed free site preparation Use hydro seeding or conventional transplanting w/minimal soil disturbance

27 Weed mat remains in place until ready to plant

28 An alternative approach to vegetable crop Site preparation 1. Requires a significant change in farming concepts 2. Requires the use of woven black plastic mulch on a commercial scale 3. Opportunity to develop hydro seeding for crop establishment 4. Allows for no-till planting of cover crops and cash crops 5.

29 Hydro seeding mix includes seeds, mulch (recycled paper + processed straw), tacifier, nutrients and growth stimulants. Hydro seeding has traditionally been used to seed road cuts or other hard to reach sites

30 Small 50 gallon hydro seeder = $ Components: Tank Trash pump Hoses Manifold Uses hydraulic Agitation from pump

31 Seeds not suitable for incorporation into hydromulch mix, place on soil surface and cap with hydromulch to prevent bird damage and blowing w/wind.

32 What crops and or cover crops can be adapted to this form of seeding? Precision seeding for banding crops over drip lines Seeding width based on nozzle type Tractor mounted for Longer rows Consistent delivery of seed/mulch mix

34 Consider the concept of a crop module instead of a crop field Basic size of crop module is 2 planting beds Row length = weed mat roll, 300 ft. Width of beds = 6 ft. Width of weed mat = 8-10 ft.

35 Weed mat left edge secured in trench, right side secured with water hose
