Which of the following is true of India? The dramatic decrease in the number of rice varieties planted puts the food supply at risk. Use of pesticides have remained stable over the past century. There has been an increase in the diversity of corn crops due to deliberate efforts. Antibiotic resistance is unlikely to be a problem. The effects of climate change are unlikely to have strong effects on agriculture.

Which strategy would you recommend to address this issue? Access inputs from alternative sources Increase application of synthetic fertilizers Plant cover crops Let the land rest unplanted
(10)Sustainable agriculture consists of farming and grazing that maintain the healthy soil, clean water, pollinators, genetic diversity, and other resources needed for the production of crops and livestock over the long term. Strategies undertaken toward this end include all of the following EXCEPT: Increased use of new fertilizers without waiting years to test their viability moving back toward the more traditional model of agriculture genetic engineering of crops and livestock Reduction of fossil fuel inputs
With regard to industrial agriculture, it is distinct from traditional agriculture in that: Its development tends toward monocultures Its development tends toward polycultures Its development involves an equal blend of monocultures with polycultures It is less well integrated into market economies, producing less excess food to sell
How is integrated pest management (IPM) different from other forms of pest control? O IPM only supports mechanical control of pests in an area. O IPM tolerates a low number of pests in an area. O IPM favors the generation of herbicide-resistant weeds. O IPM prohibits the use of herbicides in an area. O IPM suggests the use of herbicide-resistant plants.
Which of these is the most effective as an action that a farmer could take to help to mitigate climate change? Burn the land regularly to remove debris and prepare for planting Use modified plowing in a conservation tillage method Use a no-till technique to avoid plowing the land Plow the land regularly to prepare for planting Find ways to encourage erosion as a way of refreshing the land
