B – chemical symbol for boron
Bray 1 Phosphorus – soil testing procedure that is used to determine the level of plant available phosphorus in soils with a pH of 7.4 or less
Buffer Index – soil test measurement that is used to determine the amount of liming material required to raise soil pH to the desired level; the buffer index is measured only when the pH of a mineral soil is less than 6.0
Ca – chemical symbol for calcium
Cu – chemical symbol for copper
#ENP/A – abbreviation for pounds of Effective Neutralizing Power per acre; ENP units provide a uniform way of expressing the lime requirement, because liming materials differ in their purity and particle size distribution and these characteristics determine their neutralizing capacity in the soil; the label on liming materials will tell you the pounds of ENP per ton of product
Fe – chemical symbol for iron
K – chemical symbol for potassium
K2O – see Potash
lb/A – pound per acre
lbs - pounds
Mg – chemical symbol for magnesium
mmhos/cm – millimhos per centimeter; a unit of electrical conductivity that is used to express the relative concentration of soluble salts in the soil solution
Mn – chemical symbol for manganese
N – chemical symbol for nitrogen
Nitrate (NO3-N) – plant available form of nitrogen that occurs in the soil; nitrate may be readily leached through the soil
Olsen Phosphorus – soil testing procedure that is used to determine the level of plant available phosphorus in soils with a pH greater than 7.4
P – chemical symbol for phosphorus
Phosphate (P2O5) – terminology and chemical formula used to express the amount of phosphorus in a fertilizer recommendation or in a bag of fertilizer
pH – measurement of the acidity or alkalinity of the soil solution
Potash (K2O) – terminology and chemical formula used to express the amount of potassium in a fertilizer recommendation or in a bag of fertilizer
ppm – parts per million
Sulfate (SO4-S) – sulfate, a plant-available form of sulfur that occurs in the soil
Soil Texture – relative proportion of sand, silt, and clay particles in a soil, which determine the soil type (e.g. silt loam or clay loam)
Soluble Salts – ions (charged atoms or molecules) that are dissolved in the soil solution
sq. ft. – square feet
Zn – chemical symbol for zinc
