Research Project: Long-Term Tillage Influence Soil Quality and Carbon Cycling in Dryland Cropping System

Location: Central Great Plains Resources Management Research

Project Number: 3010-12210-004-06-N
Project Type: Non-Funded Cooperative Agreement

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

Objective:
Long-term tillage influence on soil health and carbon cycling

Approach:
A field plot experiment was initiated in 1969 to investigate the effects of tillage intensity on winter wheat-fallow rotation. The three tillage treatments were moldboard plow (plow), sub-tillage (ST), and no-tillage (NT) arranged in randomized complete blocks with four replications. The native sod plots were also included within the experimental design for comparison with the cropping system and the tillage practices. Soil samples were collected to evaluate changes in soil quality parameter. The USDA-ARS scientist will quantify some aspect of soil quality parameters (such as aggregate) including soil carbon content in this study site.
