For example, the mid-range nitrogen fertilization for bahiagrass is 125 pounds and the corresponding carrying capacity is 1.0 AU per year. In this instance, the cost of the bahiagrass will be $123 per acre and the annual cow cost for bahiagrass pasture would be $123. Conversely, at the high rate of 150 pounds of nitrogen per acre and a carrying capacity of 1.5 AU per acre, bermudagrass has cost of $208 per acre and a cow cost of $139 per cow per year.
Polar Bond Definition: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed.This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative.Polar bonds are the dividing line between pure covalent bonding and pure ionic bonding. Examples: Water is a polar bonded molecule.his causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative. Polar bonds are the dividing line between pure covalent bonding and pure ionic bonding. Examples: Water is a polar bonded molecule.
Polar bonds happen when two atoms form a molecule using a covalent bond. When the two atoms share electrons, there is also a change of electron density. If the electrons are not shared equally, then there will be a partial ionic charge. This happens most often in atoms with a large difference in their electronegativity.
