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.
No. Hydrogen bonds exist between two polar molecules that contain hydrogen. Polar molecules have partially positive and negative ends. In hydrogen bonds, the partially positive end of one polar molecule is attracted to the partially negative end of another polar molecule. Bonding between non-metals consists of two electrons shared between two atoms. In covalent bonding, the two electrons shared by the atoms are attracted to the nucleus of both atoms. Neither atom completely loses or gains electrons as in ionic bonding.
