Organics Proceedings Published in Crop Management Journal


The proceedings of ‘USDA Organic Farming Systems Research Conference,’ which took place in March 2011 at Georgetown University in Washington, D.C., has been launched on PMN. This open-access collection of research, reviews, and perspectives provides a diverse discussion around organic farming systems in the United States. Presentation topics run the gamut of dimensions, from the agronomic and economic to the ecological and social. View proceedings.

Forage and Grazinglands is a peer-reviewed, applied journal covering the many aspects of rangeland management. This resource provides research, reviews, guides, briefs, and news to help users better manage their rangelands and their stock for meat and dairy production. Individuals can access Forage and Grazinglands and all other Plant Management Network resources for just $38-$45 yearly. Subscribe Today!

Increase Double-Cropped Soybean Yield Through Latest ‘Focus on Soybean’ Webcast


This presentation by Dr. David Holshouser, Associate Professor and Extension Agronomist at Virginia Tech, helps consultants, growers, and other practitioners in the Mid-Atlantic region implement practices to increase yields of soybean planted after small grain harvest. Specifically, the presentation discusses the main differences between full-season and double-cropped soybean and makes recommendations to enhance double-cropping advantages and minimize disadvantages. By the end of this presentation, viewers will better understand practices and techniques that will allow them or their clients to improve double-cropped soybean production.

The Effects of Glyphosate, Glyphosate Management Discussed in ‘Focus on Potato’


In this talk, Dr. Andrew Robinson, Assistant Professor and Extension Potato Agronomist at North Dakota State University, helps growers, consultants, and other practitioners in all regions of the potato industry to better understand and identify the effects of glyphosate in potatoes and how it can be managed. The presentation provides a short background on glyphosate, describes injury symptoms of glyphosate in potatoes, and details symptoms of glyphosate residues that remain in seed through storage and are planted the following year. Strategies to manage glyphosate in potato are also discussed.

PMN Produces Two New ‘Focus on Corn’ Webcasts:


Irrigated Water Management Tools: This two-part webcast is authored by Dr. Bill Kranz at the University of Nebraska-Lincoln. In Part I of the presentation, Dr. Kranz discusses procedures for preparing soil water sensors and how to install them in the field. In Part II, Kranz teaches viewers how to use a modified atmometer to verify that soil water sensors are responding correctly. Several water conservation practices are also discussed in this talk, including crop residue management, planting a shorter season hybrid and reducing the plant population. By the end of the presentation, the viewer will have the necessary information to initiate an irrigation scheduling program and find additional information.

Nitrogen Management of Corn Related to Weeds: This learning module by Dr. Laura Lindsey, Assistant Professor at The Ohio State University, addresses three specific questions: “How does nitrogen application rate and critical time of weed removal influence corn grain yield?” “How much nitrogen do weeds remove?” and lastly, “What happens to nitrogen in weeds?” By the end of this presentation, the user should know more about nitrogen uptake of weeds in a corn grain production system and how that nitrogen is eventually released back to the soil after weeds are controlled.

Proper Handling of Round Cotton Modules Featured in Latest ‘Focus on Cotton’ Talk


This presentation by Dr. Tommy Valco, Cotton Technology Transfer Coordinator at USDA-ARS, will help cotton producers, custom harvesters and ginners reduce the chance of plastic contamination in the cotton bale. The rapid adoption of round modules has caused some problems and concerns in the handling and processing round cotton modules. When round modules are handled improperly, the potential for plastic contamination in the cotton bale is increased. This presentation will review the proper methods of handling round modules in the field and the gin.
