question 12 points 3\nhow do farmers increase their productivity?\n○ using chemical fertilizers and pesticides in crop fields\n○ following shifting culture\n○ using sewage water directly in crop fields\n○ removing weeds by hand

Answer

Brief Explanations:

Chemical fertilizers can provide essential nutrients to crops and pesticides can protect them from pests and diseases, thus increasing productivity. Shifting culture is a traditional and less - productive method. Using sewage water directly can introduce contaminants and harm crops. Removing weeds by hand is time - consuming and less efficient compared to using fertilizers and pesticides for large - scale productivity increase.

Answer:

Using chemical fertilizers and pesticides in crop fields
