In the Southeast, a conventional crop rotation is two years of cotton followed by two years of peanuts. In this extended interview, Ron Bartel explains why farmers should consider a grass rotation, as well.
Since we last covered the California drought, conditions in the state have stayed, well, dry—very dry. Statewide, total precipitation is about equal to or below the lowest three-year period since 1895.
Despite uncertainties around future precipitation change, it is clear that as temperatures rise in Colorado, the state is expected to face significant challenges to managing water resources, according to a new report.
In this activity, students explore what types of energy resources exist in their state by examining a state map and data from the Energy Information Administration. Students identify the different energy sources in their state, including the state's renewable energy potential.
These flow charts show carbon dioxide emissions for each state, the District of Columbia and the entire United States. Emissions are distinguished by energy source and end use.
This activity challenges students to try and meet the world's projected energy demand over the next century, decade by decade, by manipulating a menu of available energy sources in the online Energy lab simulator all while keeping atmospheric CO2 under a target 550ppm.
