Research Project: Long-term Beef Manure Influence Soil Quality, Carbon Dynamics, and Corn Productivity

Location: Central Great Plains Resources Management Research

Project Number: 3010-12210-004-08-N
Project Type: Non-Funded Cooperative Agreement

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

Objective:
1. Long-term influence beef manure and commercial fertilizer on soil quality parameters and soil C dynamics. 2. Long-term tillage influence of corn yield.

Approach:
Field plots experiment was initiated in 1990 to investigate the effects of beef manure and commercial fertilizer on soil quality and soil carbon content in a continuous corn productive system near Manhattan, KS. The study consists of two tillage treatments, conventional tillage (CT) and no-tillage (NT). The experiment arranged in a randomized complete block design with four replications. Soil samples were collected to evaluate changes in quality parameters. The USDA-ARS scientist will quantify some aspect of soil quality parameters (such as aggregate and aggregate-associated carbon) and long-term yield.
