______________ subsidy
The fossil fuel energy and human energy input per calorie of food produced.
Green Revolution

An agricultural technique in which trees and vegetables are grown next to each other in rows or other patterns.
No-till agriculture
An agricultural method in which farmers do not turn the soil between seasons as a means of reducing topsoil erosion.
Integrated pest management (IPM)
