With corn planting off to a very slow start this year, few people have been worrying about getting soybeans planted. Though we’ve been saying in recent years that early planting of soybean helps increase yield potential, corn typically loses yield faster than soybean as planting is delayed. So it is appropriate to plant corn first, before soybean.
How early is “early” when it comes to soybean planting? Based on planting date responses we have seen in recent years,…
April 2013 has turned into a “second March”, with wet weather and cool temperatures persisting into the last week of the month, and corn planting progress stuck at 1 percent, with little chance of much additional progress before the calendar turns to May. Nationally, only 4 percent of the corn crop was planted by April 21, and none of the Corn Belt states had more than 1 percent planted. The corn that has been planted is struggling mightily to survive the soil conditions and to emerge.…
Yes, a year does make a lot of difference – in 2012, we had 5 percent of the Illinois corn crop planted by April 1 and 17 percent planted by April 9. This year, the April 8 issue of Illinois Weather & Crops from the Illinois office of NASS gives no percentage planted as of April 7, which means that less than 1 percent had been planted. There has been some planting this week,…
Last fall, with funding provided through the Illinois Council for Best Management Practices (C-BMP), GROWMARK, C-BMP, and the University of Illinois initiated the N-Watch soil sampling program to see how much inorganic N remained in the soil following the drought of 2012.
Fall sampling revealed fairly high amounts of soil N, with 151 samples statewide averaging 19.5 ppm of nitrate-N in the top foot of soil. We multiply this time 4 to get lb of N per acre,…
