  • Comparison of root maggot pupae survival under conservation tillage versus conventional tillage practices
  • Comparison of flea beetle and thrips survival in various stubble heights
  • Comparison of incidence and economic impact of insects (Mession fly, thrips, canola root maggot, wheat stem maggot, cut worms and grasshoppers) and native predators (spiders, ground beetles) under various conservation and conventional farm practices
Pasture/rangeland rejuvenation
  • Direct seeded versus conventionally tilled and seeded pasture
  • Pre-seeding herbicide on pasture versus conventionally tilled and seeded pasture
Soil moisture management
