Concurrent exposure assessments of atrazine and metolachlor in the mainstem, major tributaries and small streams of the Chesapeake Bay watershed: Indicators of ecological risk
The use of biomass crops as an energy source is frequently mentioned as an option to reduce CO 2 emissions. To evaluate the possibilities reliable yield estimates of biomass crops are required. In this paper a simple method is developed to estimate regional yields of various biomass crops, based on the linear relation between intercepted light and biomass production. The quality of the estimates was studied by using the method to estimate yields of several agricultural crops in two regions in The Netherlands. In general a deviation of less than 10 % was found between actual and estimated average yield.
