Posted by | February 20, 2021

Principal investigators:

  • Charles Wortmann

Associated with:

  • University of Nebraska-Lincoln and ARS

Project Summary:

This includes field research with different solid organic materials including livestock manures, municipal biosolid products, and an industry bi-product. The research addresses two broad objectives:

  1. Improved pre-plant estimation of the fertilizer N substitution value of different organic materials and the effects of CN, concentrations of lignin, cellulose and hemicellulose as well as soil, climate and management conditions. It addresses the year of application and two following years.
  2. Adaptation of sensor guided in-season N application for manured yields.
