  1. Precision Agriculture In No-till Production Systems Courtney Dunkel SOIL 4213

  2. Objectives • Differences between Conventional and No-till • Benefits • Disadvantages • Equipment

  3. What is tillage? • The agricultural preparation of the soil by mechanical aggregation of various types such as digging, stirring, and overturning. • The preparation of land for growing crops.

  4. Conventional Tillage • Wet soils • Bury weed seeds and residue • Uniform incorporation of fertilizers and pesticides

  5. Advantages • Suited for poorly drained soils • Optimum seed bed • Excellent incorporation • Equipment

  6. Disadvantages • Soil erosion • Moisture loss • Timeliness considerations • Highest fuel and labor costs • Compaction

  7. Conservational • At least 30% ground cover after planting • Several different types of conservational tilling • Ridge-till • Strip-till • Mulch-till • No-till

  8. No-till • Farmer’s attitude • Produce crops while making soil improvements • With runoff and erosion virtually eliminated, SOM and CEC improvements are possible over time

  9. Advantages • Erosion control • Moisture conservation • Wildlife benefits • Beneficial insects • More intensive use of steeper fields • Terraces and grass waterways can be minimized • Row direction makes little difference • Minimum fuel and labor • Reduced compaction

  10. Disadvantages • Corn on corn problems • No incorporation Stalk Stompers • Increased dependence on herbicides • Slow soil warming on poorly drained soils • New equipment
