Crop Residue and High-Carbon Char: Potential Soil Conservation Tools May 8, 2018

Soil is the single most important resource on which our agriculture depends. Proper soil management is necessary to sustain long-term agricultural productivity. Soil loss through erosion or run-off hurts agricultural production with depletion of organic matter and fertility. It also has environmental implications.

Feasibility of Sensor-Based Nitrogen Fertigation Management in Corn May 7, 2018

Averaged across two years, the sensor-based N fertigation treatment consistently resulted in higher profit and nitrogen use efficiency. The use of fertigation offers the unique capability to minimize N losses by reacting to slight N deficiencies in corn by applying N multiple times throughout the season with lower application rates.

Implementation of Cover Crops in Corn and Soybean Systems in Nebraska November 29, 2016

A short review of cover crop research conducted at four University of Nebraska research fields (two irrigated, two dryland) to study the feasibility and impact of winter cover cropping on soil quality, soil water, and crop yields in corn-soybean systems. Objectives were to quantify cover crop emergence, fall and spring biomass production, soil water changes, soil chemical and physical property changes, and crop yields.
