|Prevention and Control of Palmer Amaranth in Cotton||
Palmer amaranth (Amaranthus palmeri), a member of the "pigweed" family, is one of the most troublesome weeds in many southern row crops. Seed can germinate all season and plants can grow to over 6 feet in height. Plants have either male flowers that shed pollen or female flowers that can produce up to 600,000 seed per plant. One Palmer amaranth per 30 foot of row can reduce cotton yield by 6 to 12%.

|Virginia Cotton Production Guide 2016||
Proper soil fertility management ensures sufficient nutrients for maximum cotton production. Obtaining and maintaining appropriate soil nutrient concentrations is imperative, as fertilizer inputs are the largest component of production budgets for Virginia cotton farmers. At the same time, excessive nutrient application wastes money, wastes natural resources, and can negatively impact yields and environmental quality.

|The Nutrient Value of Straw||
The mature and dried stem, leaves, and chaff remaining after barley and wheat are harvested is known as straw. Many farmers around Virginia harvest straw by baling in small bales, large round bales, or large square bales that range in weight from 40 to 1,000 lbs. plus per bale.

|Yellow Corn in Virginia – Spring 2016||
Many of the corn fields on the Eastern Shore and in Eastern Virginia are “yellow” and stunted due to the weather this Spring (Figs. 1 and 2) and is similar to conditions that Virginia farmers experienced in Spring 2010. There are many reasons for the corn to be yellow that range from nutrient deficiencies to abiotic factors.

|Yellow Corn in Virginia – Spring 2017||
According to Meteorologist Scott Minnick with the NOAA-National Weather Service in Wakefield, VA, May 2017 is “yet another wet and cloudy May for the record books. With the rain on [May 31, 2017], Norfolk moved up to the 3rd wettest May on record.” The 2017 growing year is almost identical to last year (the wettest May on record for Norfolk, VA), with a dry March and April leading into a record breaking cool and wet May as corn tries to establish roots. Young corn largely depends on residual and starter fertilizer prior to sidedress applications and these fractions can be impacted greatly with excessive rain.

|Enhanced Efficiency Fertilizer Materials: Nitrogen Stabilizers||
The recent increase in fertilizer costs, especially nitrogen fertilizers, has resulted in technologies that may improve nitrogen use efficiencies in agronomic cropping systems. Many of these technologies are designed as fertilizer additives to increase fertilizer use efficiencies by increasing plant fertilizer uptake and crop yields. The resulting fertilizer formulations include some type of extra additive within the formulation or applied as a coating and are often referred to as “enhanced efficiency fertilizers” (EEFs).
