Folks are getting planters ready\nand making sure everything is in working order. Here\u2019s some good planting info,\nmostly from the UGA Corn production guide.<\/p>\n\n\n\n

Do not underestimate the importance\nof good plant stands. Improper establishment will have a negative impact on\nyield as corn can be sensitive to planting depth, thick or thin populations,\nhighly variable spacing, and delayed emergence. Inspect and service your\nplanter and replace worn parts. Utilize the expertise that planter companies\nhave to gain insights on properly adjusting all parts to changing soil and\nweather conditions as to optimize the operation.<\/p>\n\n\n\n

Ensure that coulters and disc\nopeners are aligned accurately and the planter is level when you begin\nplanting. Calibrate the planter for a proper seed drop. Make sure seed is\nbetween 1.5 and 2 inches deep. Avoid too much down pressure especially when\nwet<\/strong> but make sure the furrow is closed properly. Check your speed to ensure\nthat seed spacing is correct so as to avoid differences in plant emergence. Speed\ncan increase your stand spacing so optimize your planting speed according to\nyour seed density and the ability to reduce the spacing differences at seed\ndrop. <\/p>\n\n\n\n

Avoid\nplanting when soil temperatures drop below 55 F. Variable plant emergence can\nreduce yields as much as 10 to 20% depending on the establishment delay of\nneighboring plants. Delayed plants cannot compete with older, better\nestablished plants. A field where all plants emerge within 12 to 24 hours of\nthe first emerging plant is considered a successful stand that may provide a\nhigh yield potential for you to manage.<\/p>\n\n\n\n

Plant\ncorn as soon as temperature and moisture become favorable for seed germination\nand seedling growth. Soil temperature in the seed zone should be 55\u00b0F or\ngreater before planting. Corn seed will sprout slowly at 55\u00b0F while germination\nis prompt at 60\u00b0F. One should delay planting if cold weather drops soil\ntemperatures below 55\u00b0F at the two-inch soil level. It is generally safe to\nplant if soil temperatures are 55\u00b0F and higher, and warm temperatures are in\nthe forecast. Extremely early planting introduces a risk to frost or freeze\ndamage and subsequent loss of stands. Usually, as long as the growing point is\nbelow ground level, corn can withstand a severe frost or freezing damage\nwithout yield reduction. It is best therefore to monitor soil conditions and\nweather if your desire is to plant as early as possible. Generally, it takes\ncorn seed 7 to 12 days to emerge when planted in soils at 55\u00b0F. <\/p>\n\n\n\n

Early-planted\ncorn typically out-yields late-planted corn. Depending on your location,\nplanting dates may range from early March in south-Georgia to mid-May in north\nGeorgia. Early planting helps avoid periods of low rainfall and excessive heat\nduring pollination, both of which lead to internal water stress during critical\nperiods of corn development.<\/p>\n\n\n\n

Right\nnow (9 am on Friday, Feb 21) we have 2 inch soil temperature of 49, going back\nin order last 5 days were 61, 67, 65, 59, 54, average 2 inch soil temperature\nin Seminole County, Ga . So soil temp is pretty good but will likely drop this\nweekend.  We don\u2019t want to plant when too wet as we\u2019ll get side wall\ncompaction and other problems that aren\u2019t good.  Avoid planting when big\nrains or hard cold are in the 3 day forecast.<\/strong><\/p>\n\n\n\n

Planting\nCorn after Corn<\/strong><\/p>\n\n\n\n

Corn\nlast year and repeating in the same field in 2020<\/strong><\/p>\n\n\n\n

I\u2019m\nhearing that we will have some corn after last year corn in the same field.\nWhen we do this it increases the risk of certain diseases so we need to watch\nout for them. You\u2019ll want to closely watch those fields for early incidence of\nNorthern Corn leaf Blight (NCLB) and Southern Corn Leaf Blight(SCLB). They can\ncome in off the old stalks from last year sometimes. A good thing to do is\nplant a corn hybrid in these fields that is resistant to these diseases.<\/p>\n\n\n\n

Corn\nCheckoff<\/strong><\/p>\n\n\n\n

Every\n3 years corn growers vote whether to continue the corn checkoff. This 1 cent\nper bushel goes to field corn research, education and promotion.<\/p>\n\n\n\n

This\nis the year for that and growers should get this in the mail in the next couple\nof weeks. <\/p>\n\n\n\n
