Straight Stalk 2015

ACES Global Academy trip to the International Rice Research Institute in the Philippines.

Tomorrow I will spend "two days" on airplanes. Last fall I was nominated by my boss, ACES Associate Dean and Director of Extension, Dr. George Czapar to be a fellow in this year's ACES Global Academy cohort. This program is funded by a generous private endowment to expose ACES faculty to international issues and facilitate collaboration with potential international research partners. This year's cohort is focused on international food security and climate change.A few weeks ago we were in...

Soybean not a fan of bright lights/big cities

Why do soybean plants near street/highway lights stay green until frost?While corn plants love light and heat in their rush to harvest. Soybean plants are night owls. The soybean varieties we grow in Illinois are grouped by Maturity groups with groups II, III and IV being the most common in Central Illinois.

If you look at annual graphs of soil available K, September is traditionally the low point in the cycle, but normally the levels rebound quickly after harvest. The lack of fall rains, this year, has delayed that...

First Corn Planting

No April Fools joke, corn planting started at the South Farm yesterday.

Heat units will not likely accumulate very fast but I will start tracking using the U2U Corn GDD tool. Average weather would predict emergence around the 19th or 20th of April.
