Nitrogen fertilizer is a major cost in corn production and is a big lever that drives yield. However, not every pound of N fertilizer yields the same return on investment. The first several dozen pounds applied to a corn crop yields large returns in grain, with subsequent pounds still offering returns, but not as effective as before.
Tillage to remove and speed-up the decomposition of crop residue will help to reduce the risk of tar spot as well as other diseases such as gray leaf spot and northern corn leaf blight that overwinter in infected stubble. This will be particularly important to reduce disease development in 2022, given that in many fields, most of the stubble that remain after harvest came from a 2021 crop with high levels of disease.
Due to the increase in fertilizer prices, there is renewed interest in the nutrient value of manure. This article will discuss bedded-pack manures that involve straw, sawdust, or wood chips to absorb moisture. The nutrients and organic matter in pen-pack manure are an excellent addition to farm fields.
The most common types of bedded manure are beef, dairy, and sheep or goats. Small ruminant bedded pack manure contains the most nutrients per ton followed by beef manure and dairy manure.
Join the Ohio State University’s Water Quality Extension Associates for a webinar series discussing topics related to water quality, ranging from Phosphorus and agricultural Best Management Practices (BMPs) to watershed planning and technology. Webinars will run from December 2021 to March 2022 and will be recorded for later viewing. All live WQW webinars will offer Certified Crop Advisor continuing education credits, and relevant topics will provide Certified Livestock Manager credits.
Just as ag technology is always updating, so to is Precision University. This year our focus is Using Ag Technology to Manage 2022 Challenges. Based on feedback from last year, it will be delivered in 2 webinars and a half-day, in-person event.
The January 5 webinar will focus on adapting to supply chain shortages. A panel of industry representatives will share what they are seeing and how to work around what you might not have.
