Timely Viticulture: Pre Bloom
The annual goal in the established vineyard is to have the vines fill their allotted trellis space, top out vegetative growth just above the top wire at veraison, and produce a crop that is in balance with the vegetative vigor. Regretfully high water availability and high nitrogen (N) content of...

Webinar: Is There a Best Way to Fertilize Corn with Nitrogen? (1 CEU)

Tuesday, Dec. 4, 2018 - 12:00pm to 1:00pm
Online
An American Society of Agronomy webinar sponsored by Verdesian Life Sciences. Assuring adequate nitrogen (N) availability during key stages of plant growth is a major factor affecting yield and profitability of corn. Nitrogen uptake by modern corn hybrids follows a sigmoidal pattern over time with...

Reducing Nitrogen Applications in Watermelon While Maintaining or Increasing Yields

2008 Objective: With the emphasis on reducing excess nutrients applied to Maryland vegetable fields, which will reduce nutrient movement into the Chesapeake Bay, this research examined supplying nitrogen to watermelon plants only when needed as determined by the plant’s nitrate content...
