Potassium May Need To Be Replenished

As 2010 gets underway and growers plan for the upcoming crop season, applying potassium (K) fertilizer may be more important than ever. According to a study released last fall by the International Plant Nutrition Institute (IPNI), 39 percent of the soils across North America were in negative balance for K, and this study didn't take into consideration the cutbacks of the 2009 growing season.

Snowpack Brings Mixed Bag For Soils

The heavy snowpack covering Iowa's farm fields hides many secrets, including a future this spring that could mean flooding and significant, damaging runoff of Iowa's topsoil and its crucial nutrients.

No-Till, Cover Crops Could Help Nematodes Thrive

Weeds and cover crops could be a good host to nematodes. Reduced tillage may spread other pests, like soybean cyst nematode, but that's not a concern with corn nematodes. They are in every field already. However, reduced-tillage producers should be aware that some corn nematodes are sensitive to soil movement and research suggests no-till or strip-till may actually increase corn nematode populations.

Illinois Grower Takes Strip-Till Plunge

When Jason Lay attended a conference last year with other Illinois farmers, he was amazed by the level of interest in strip-till, a system in which the crop is planted in a narrowly tilled strip and most crop residue is preserved to protect the soil from erosion.

Manage Iron-Deficiency Chlorosis With Varieties

Variety selection is one of the best ways to manage iron-deficiency chlorosis (IDC) problems in soybeans. IDC symptoms include yellowing between the veins of the trifoliate leaves and can result in growing-point death. With precision planting and global positioning systems, it is may be possible in the future to plant two different varieties on the same field.

Don't Rely On Chemicals For Moldy Grain

Growers may be concerned about moldy grain and vomitoxin development in storage, but they shouldn’t rely on chemical treatments to prevent any further contamination, says an Ohio State University Extension plant pathologist.

Nitrogen Release From Vetch, Clover Studied

In collaboration with the Organic Grains Research group, Mary Parr, graduate student in the Soil Science department at NCSU, has been investigating nitrogen (N) fixation and release in a system involving roll-killed winter legume cover crops followed by no-till organic corn.

Access Wet Field With Conservation Care

Farmers who still have crops in their fields are acting quick to access land and complete harvest operations. However, they must do so in a careful manner and be mindful of their conservation credo, according to Illinois State Conservationist for the Natural Resources Conservation Service (NRCS) Bill Gradle.

Best P Placement With Strip-Till Depends On Soil Test

Traditionally, fertilizer phosphorus (P) is band-applied 6 to 7 inches deep in the strips at the time of strip tillage. This placement is thought to be ideal in terms of fertilizer use efficiency, early plant growth, and high yields. However, little research has been conducted to determine the optimum placement of P in strip-till systems.
