ASSESSING CORN AND SOYBEAN STANDS

 

  • Early assessment of corn and soybean stands can help identify potential crop concerns early in the season. 

  • Once seedlings emerge, stand counts and visual inspection of the plants can help to identify problems from planting, insects, and/or diseases. 

  • Three common methods for taking stand counts are the 1/1000th acre method, the wheel method, and the hoop method.

Corn Planting Depth 

Variability - Why Does It Happen and What Can We Do About It? 

Planting depth is the first and one of the most important things to prioritize on the road to maximizing yields. Variability in planting depth can happen even in the same field or change over time with the same planter. The most common problem with variability in planting depth is uneven emergence and poor root growth. Although this type of problem may not be very noticeable early in the season, the stress will carry through the entire growing season and ultimately impact yields in the fall.

CORN GROWTH STAGES AND GROWING DEGREE UNITS
  • A corn plant requires a certain number of growing degree units (GDUs) to reach maturity, regardless of the number of calendar days it takes to accumulate.

  • The relationship of GDU accumulation and corn development, along with utilizing the estimated number of days to reach a certain growth stage, can help predict when important growth stages will occur.

  • Growth stages can be used to help growers make timely applications of herbicides and fungicides. The following information is on corn growth and development from emergence to R6 growth stage.

Corn growth stage development can vary according to corn maturity. An early maturing pro

Zinc.  Of all the micronutrients, zinc stands out as one of the most critical ones in all of Winfield United’s research.  That is why we add the zinc coating Fortivent ZN to all new production of Croplan hybrids.  One of the main functions of zinc is to provide energy to a plant.  Our agronomists often refer to zinc as being the “forklift” to get other nutrients into the corn plant.  A few years ago, Winfield United analyzed a set of NutriSolution samples and found that where zinc was adequate, N, P, K, and S were adequate at least 85% of the time.  However, when zinc was deficient, N, K, and S were deficient 60-70% of the time and K was deficient one third of the time.

WEED CONTROL

As we look towards post emerge weed control, we can look back and say “that was an interesting spring.” From starting off very cold to running pivots in May and planting the majority of the crop in a 14 day period,it was definitely interesting.Thanks for your support this spring and we look forward to servicing your needs this summer.
