Historical yield trends offer a glimpse into the future.
Corn grain yields in the U.S. have steadily increased since the late 1930’s.
In recent years, a new era in crop management has been centered around biologicals that have targets associated with pest control, improved nutrient supply and uptake, and overall plant growth and resiliency.
This summary is based on 55 field scale research trials conducted at Purdue Ag. Centers and with on-farm collaborators around the state of Indiana from 2014 – 2022.
Sulfur Deficiency
Sulfur (S) deficiency has become more common in
Indiana crops because S emissions from coal-fired power
plants have decreased over the past few decades
(Camberato et al., 2022). Consequently, atmospheric S
deposition to soils has also decreased.
Sulfur deficient corn plants exhibit a general yellow-
green color from top to bottom of the plant, often also
with visible leaf striping (Fig. 1). Other nutrient deficiencies
can cause striping and can sometimes be confused with S
During the heat of planting, one thing that often can be forgotten is thoroughly checking and understanding two items, 1) what seed depth am I planting at? and 2) is my seeding depth consistent, especially across all of my individual row units?
Along the way it was easy to see the beige-bronze warm-season perennial bunchgrass broomsedge bluestem (Andropogan virginicus) in many grass-dominant pastures and hayfields.
The Heart of America Grazing Conference will take place from February 20th to 21st, 2023, at the Ferdinand Community Center in Ferdinand, IN. Hosted by the Indiana Forage Council (IFC), with input from Purdue Extension, the annual event will feature forage and grazing experts from across the nation. Speakers will lead discussions on cutting-edge research in grazing, soil science, and grazing options with cattle and small ruminants, among other key topics. Keith Johnson, professor of agronomy at Purdue University, says “Participants will have the opportunity to interact with a team of presenters on what is needed to develop and put in place an effective grazing plan.” He continues, “Ways to improve grazing efficiency, how to develop and maintain healthy soil, and important recordkeeping items will be shared. There will be ample opportunity to interact with input providers at the tradeshow and to make connections with other attendees.” Highlighted speakers include[Read More…]
Field research trials are an important part of understanding how specific agronomic practices can improve farm productivity.
