Definitions

B – the chemical symbol for boron

Bray 1 Phosphorus – a 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 – a soil test measurement that is used to determine the amount of lime 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 – the chemical symbol for calcium

Cu – the 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 – the chemical symbol for iron

– the chemical symbol for potassium

K2O – see Potash

lb/A – abbreviation for pounds per acre

LBS - abbreviation for pounds

Mg – the chemical symbol for magnesium

mmhos/cm – millimhos per centimeter; a unit of electrical conductivity that is used to measure the relative concentration of soluble salts in the soil solution

Mn – the chemical symbol for manganese

N – the chemical symbol for nitrogen

Nitrate, NO3-N – a plant available form of nitrogen that occurs in the soil; nitrate is also readily leached through the soil

Olsen Phosphorus – a soil testing procedure that is used to determine the level of plant available phosphorus in soils with a pH greater than 7.4

P – the chemical symbol for phosphorus

Phosphate, P2O5 – the terminology and chemical formula used to express the amount of phosphorus required in a fertilizer recommendation and the amount of phosphorus in a bag of fertilizer

pH – a measurement of the acidity or alkalinity of the soil solution

Potash, K2O – the terminology and chemical formula used to express the amount of potassium required in a fertilizer recommendation and the amount of potassium in a bag of fertilizer

ppm – parts per million

SO4-S – sulfate, a plant-available form of sulfur that occurs in the soil

Soil Texture – the relative proportions 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. - abbreviation for square feet

Zn – the chemical symbol for zinc
