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 No-Till Fact Sheet Series Number Six - Nitrogen Fertilizer Sources and Properties | The most commonly available nitrogen fertilizer sources used in Virginia are urea, liquid urea-ammonium nitrate (UAN) solution, and ammonium sulfate. Ammonium nitrate is also available in some areas but its use is low relative to urea and UAN solution. Understanding the properties of these fertilizers enables managers to make better decisions as to the most effective way to use these fertilizers as well as to make economic comparisons. |

Consider Your Whole System: Nitrogen and Sulfur Leaching Potential in Virginia | Jun 25, 2018 | SPES-39NP | |||
Consider Your Whole System: Nitrogen and Sulfur Leaching Potential in Virginia | Early summer often means locally heavy and sporadic rainfall as thunderstorms deliver intense rains, and 2018 appears to be no different with many areas in eastern Virginia receiving 3+ inches of rain in a few days (Figure 1). These storms also often coincide with the timing of sidedress nitrogen (N) and sulfur (S) applications on corn. While some rainfall after sidedress is very beneficial to facilitate N movement into soil, heavy rain (2+ inches) often leaves us wondering how much, if any, of that recently-applied N remains and if additional N is needed. |
