Agronomic Yields - Weed and Fertilizer Microplots
Annual crop harvest data of corn, soy and wheat in Weed and Fertilized Microplots in Treatments 3 and 4 of the Main Cropping System Experiment at the LTER Main Site. Microplots were established to determine the effect of normal weed control and fertilization practices and the response to removing weed and nutrient limitations from the plots.
This datatable is part of the Agronomic Yields in Row Crop Agriculture dataset. This data set contains information about agronomic yields for the Main Cropping System Experiment which include treatments 1-4 (corn – wheat – soybean rotations) and after 1994 treatment 6 (alfalfa). Agronomic yields are measured during normal crop harvest; yields are determined by machine harvesters appropriate to each crop as described in the Agronomic protocol.
