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 Covalent Bonding Definition. When two atoms of the same element involves in a covalent bond to form a molecule, the shared pair of electrons will be at the exact midway between the two atoms. This means the electrons are equally shared by the atoms.: + :O $\to$ O::O or O=O. 1  Polar covalent bond can be defined as the bond which is primarily a covalent bond but shows a degree of polarity. 2  This partial polarity of the molecule is attributed to the covalent bond formed between two different atoms.
