SOYBEAN PLANTING BEGINS IN EARNEST, CORN PLANTING STILL UNDERWAY

For most of last week, inclement weather stayed out of the way and allowed Tennessee farmers to plant. Crop producers were able to follow up with another productive week. Nearly half of the state’s cotton acreage and one-fourth of the soybean acreage were planted by week’s end. With the exception of low-lying fields affected by earlier flooding, most of Tennessee’s corn for grain acreage has been planted and row crop farmers have turned their attention to planting single-crop soybeans and corn silage.

Soybean Inoculants…The Other Seed Treatment

UT’s standard recommendation is to include an inoculant where soybeans will be planted into fields that have never been planted to soybean or where soybean has not been grown in the field in the past 3 to 5 years.  There are several products on the market that contain a single or even multiple strains of Rhizobium bacteria designed to improve root nodulation and help soybean roots fix nitrogen from the atmosphere into a usable form for the plant.  Since the soybean must make 50 to 75% of its required nitrogen through this process this is pretty important stuff.  With the hectic weather this spring creating flooding and instances where lime was not applied timely folks should include an inoculant in the following situations: Continue reading

 LAPSE IN RAIN SETS OFF MOST PRODUCTIVE FARM WEEK OF THE SEASON

 Dry weather early last week triggered a big round of productive fieldwork for Tennessee producers. The vast majority of the state had not seen 4 consecutive days of dry weather since early April. In areas where flood waters receded and fields had dried, farmers were busy planting field crops and cutting hay. Continue reading

STORMS AND FLOODING CONTINUE TO SIGNIFICANTLY DELAY PLANTING

Farmers in East Tennessee were busy assessing storm damage last week as farmers in other areas braced for the effects of widespread flooding. Several acres of wheat were in standing water by week’s end. Departures from normal rainfall totals have reached double-digit levels for most areas of West Tennessee. Corn planting is three weeks behind average. Continue reading

Burndown Round 2

Author:  Comments Off on Burndown Round 2

There have been a number of calls from folks who were disappointed in dicamba + glyphosate control on horseweed (marestail). Most of the applications were applied right before this wet cold period which is probably at least part of the reason for the poor control. Continue reading

Converting a Sod or Pasture Field for Corn or Soybean

Author:  Comments Off on Converting a Sod or Pasture Field for Corn or Soybean

Another title for this article might be “It’s hard to make a silk purse out of a sow’s ear.”  This doesn’t affect everyone, but I have had enough calls this spring from folks who are looking at commodity prices and have already started the process or are thinking about taking an old pasture or sod field and converting it into either corn or soybeans.  Well maintained ‘new ground’ can yield very well and often has less disease and nematode pressure.  However, it may be impossible to make poor ground into a productive field if compaction or low soil pH cannot be corrected in time for the cropping season or at all.  Input costs must be weighed against realistic yield potential– particularly in fields that have not been limed or fertilized regularly for years.  Continue reading

Giant Ragweed Management

Just Emerged Giant Ragweed

The emergence pattern of giant ragweed varies every spring. This spring giant ragweed started emerging in mid-March and continues to this day.   The book says that giant ragweed mostly emerges in the early spring.  A few years ago we collected giant ragweed seed from plants in a fence row here at the station. We also collected some giant ragweed seed from a soybean field in Lake County.  We planted them in a field at the station in November.  Continue reading
