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: 3010-12210-004-04-N
Project Type: Non-Funded Cooperative Agreement

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

Objective:
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.

Approach:
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.
