Approximately 30 motor freight companies serve the area. The Virginia Inland Port is located in Front Royal off Interstate 81, just 85 miles north of Waynesboro. The International Port Hampton Roads (185 miles) is the largest natural deep water harbor in the world.
The organic nitrates, including nitroglycerin, isosorbide dinitrate and isosorbide mononitrate, act as prodrugs for nitric oxide (NO) which is a potent vasodilator gas. Nitric oxide activates guanylyl-cyclase in vascular endothelial cells, which increases intracellular cyclic GMP and thereby reduces intracellular calcium concentrates and dephosphorylates myosin light chains causing relaxation of smooth muscle cells.
Volatilisation of nitrogen from CAN is negligible, therefore the timing of the applications is flexible. Calcium Ammonium Nitrate can be considered as near-neutral in its effect on soil pH-and therefore can be used on soils that have a low pH without lowering further.This also means it is most suitable for using on perennial fruit crops (where soil incorporation of lime is normally difficult to achieve). âCan be considered as near-neutral in its effect on soil pH. 2  For use on perennial fruit crops (where soil incorporation of lime is difficult). 3  Contains equal parts of fast acting nitrate-nitrogen and longer lasting ammonium-nitrogen.
