- 17. Multiple Choice
All of these are soil conservation methods except
no-till farming.
contour plowing.
building terraces.
monocropping.
- 18. Multiple ChoiceAfter many years of applying the selective pesticides provironex, a farmer notices that the applications seem less effective. This is likely due tothe fact that provironex is fat soluble and has been bioaccumulating.provironex is selective, so other pests are filling the niche from the exterminated ones.provironex is persistent, and the farmer should apply less for better results.the target species has begun to evolve resistance.
