How can a farmer increase the annual yield of a field without unduly stressing that field or overusing herbicides, water, and other resources? Explore the technique of "annual cropping" in this LearningMedia lesson. Scientists at Montana State University have been investigating the feasibility of annual cropping with pulses and other nitrogen-fixing, low water-use crops for formerly fallow fields. See if your students can put their math skills to the test as they "plant" their own fields!
