Iowa Organic Cropping Systems in the News
5/8/2013 -
Research from a 13-year, side-by-side study shows that organic cropping systems can provide similar or greater yields, higher soil quality and greater economics returns compared to a conventional corn-soybean rotation.
Wet Conditions and Change in Soil Profile Nitrate
5/6/2013 -
From soil nitrate samples collected this spring, it is clear that carryover nitrate-N moved deeper into the profile or was lost to tile flow. With the overall wet spring and decrease in carryover profile nitrate, consider near normal nitrogen application rates.

Soil Profile Nitrate in Corn Fields Following the 2012 Drought
2/21/2013 -
Last summer's dry growing season has raised several soil fertility questions. In some cases, there have been relatively normal crop production and no need for management changes. In other siutations with severely damaged crops, there is potential for adjustment to nitrogen application for this year's corn crop due to carryover nitrate nitrogen in the soil profile.
Soil and Management Factors Influence Seeding Depth
2/18/2013 -
Knowing the texture of the soil in your field and its management requirements especially in dry conditions will dictate how deep seeds should be placed to have adequate available moisture for successful germination.
