Which of the following would PREVENT soil erosion on a farm? 

• over-grazing

• deforestation

• plowing

• crop rotations

A farmer discovers pests have become resistant the the atrazine she's been using so she must use larger, more frequent doses.  This is known as 

• the pesticide treadmill

• both an acute and a chronic effect

• a synergistic effect

• an antagonistic effect

IPM is likely to use all of the following techniques EXCEPT

• intercropping.

• planting herbicide-resistant crops.

• habitat creation for pest predators.

• increased use of traditional pesticides.

CAFOs make meat more economical, but may have some negative environmental impacts.  These include all of the following EXCEPT

• high concentrations of animal waste.

• increase in nutrients in stormwater runoff.

• increase in sediments in stormwater runoff.

• increased use of land area over other types of animal farming.

Which methods of irrigation is the least efficient with the highest rate of evaporation?

• furrow irrigation

• spray irrigation

• drip irrigation

• flood irrigation

Overgrazing of grasslands can lead to reduced range quality. Two of the major effects of overgrazing are

• erosion and desertification

• eutrophication and increased methane production

• higher primary productivity and ammonification

• higher fire potential and increased productivity
