2007 Sampling and Analysis
Protocol for Ontario Regulation 267/03 Made under the Nutrient
Management Act, 2002
Part 6 - Glossary
Ammonium Nitrogen: Means ammonia nitrogen plus ammonium
Analytical Run: A group of samples processed together through
each step of an analytical procedure.
Analytical Standard: A series of chemical standards of the
target analytes, used to set the relationship between instrument
response and concentration.
Blank, Method Blank: Pure Water or other type of blank (i.e.,
acid or solvent) used to monitor for contaminated reagents, glassware
and method processes.
Composite Sample: A sample that is made up of a number of
grab samples that have been thoroughly mixed together.
Contaminant: Means any solid, liquid, gas, odour, heat,
sound, vibration, radiation or combination of any of them resulting
directly or indirectly from human activities that may cause an adverse
CRM: Certified reference material; matrix sample containing
analytes at concentration values which have been certified by multiple
Duplicate Sample: One of two samples collected at a sampling
point at the same time in a manner that minimizes differences between
Geo-Reference: A specific set of coordinates within a numeric
system of grid references (e.g., latitude/longitude or UTM (Universal
Transverse Mercator)) used to precisely identify a geographic location.
Global Positioning System: Method of determining geo-reference
using a GPS receiver.
Grab Sample: A single sample taken directly from the material
being sampled, sub sample or a portion of a composite sample.
Internal Standard: A compound, representative of the compound(s)
of interest and not expected to be found in the matrix, spiked into
every sample extract and solution analyzed. It monitors losses/gains
due to the analytical procedure. Data may or may not be corrected
based on the calculated recovery.
Matrix: Any type of material, (e.g., soil, manure, sewage
Matrix Check Material: Matrix check materials are, typically,
natural materials subjected to method processes in order to monitor
method recovery.They are often in-house sample composites that have
an established value and characteristics
NMAN: A computer program of that name prepared by OMAFRA
for the purpose of preparing NMPs, as well as the workbook that
can be used to prepare plans manually.
Nitrate Nitrogen: Means nitrate nitrogen plus nitrite nitrogen.
Nutrient: A compound or element that is absorbed and utilized
by plants in the process of their growth and reproduction.
Nutrient Management Plan: A plan for the application of
materials containing nutrients to land in such a way that agronomic
requirements of crops are met, and environmental impacts are minimized.
Nutrient Unit: The amount of nutrients that give the fertilizer
replacement value of the lower of 43 kilograms of nitrogen or 55
kilograms of phosphate.
Quality Management System: A set of interrelated elements
(e.g., policies and objectives) that direct and control the way
a facility operates with regard to quality.
Replicate Analyses: Natural samples may be split in the
laboratory and analyzed together in the same run. Replicates are
taken through the entire method process. This data can be used to
assess the within-run precision of the analysis or sample matrix
Replicate Sample: An additional or second aliquot (portion)
of a randomly selected sample in the analytical run.
Representative Sample: A sample of material that has been
taken so that it has essentially the same composition and characteristics
of the source material.
Spiked Samples: Analyte(s) of interest is spiked into the
sample matrix in order to monitor recovery from the sample matrix
using the method or parts of the method.
Spiked Water/Solvent: Analyte(s) of interest is spiked into
reagent water/solvent to monitor recovery because of changes in
the method or parts of the method.
Standard Additions: The addition of known quantities of
the analyte of interest to one or more split portions of a single
sample can be used to determine the presence and possible effect
of interference by various matrix constituents on the analytical
