Research Project: Long-Term Oil Seed Production Influence Soil Quality and Carbon Content in Dryland Cropping System

Location: Central Great Plains Resources Management Research

Project Number: 3010-12210-004-004-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Apr 1, 2017
End Date: Mar 31, 2022

1. Long-term influence of different oil seed crops on soil health parameters and soil C dynamics. 2. Long-term tillage and crop rotation impact on soil quality parameters.

Field plots experiment was initiated in 2004 to investigate the effects of oil seed production (canola and soybean) in rotation with wheat, corn, and fallow cropping systems. Tillage practices (no-tillage and conventional tillage) were also included with wheat, and fallow systems. The experiment was arranged in a randomized complete block design with four replications. Soil samples were collected to evaluate changes in quality parameters influenced by tillage and cropping systems. The USDA-ARS scientist will quantify some aspect of soil quality parameters (such as aggregate and POM) and soil carbon content.
