Part 1 - Introduction

This document is the Greenhouse Nutrient Feedwater Management Protocol (GNF Management Protocol or Protocol) which is adopted by reference in whole by Ontario Regulation 300/14 (Regulation) made under the Nutrient Management Act 2002, S.O. 2002 (NMA). It sets out requirements that are complementary to and in addition to those set out in the Regulation.

The requirements of this Protocol form part of the Regulation and are legally enforceable. Anyone reading this document should ensure that they have the most recent version of the Regulation, this Protocol, the GNF Management Table and the GNF Sampling and Analysis Protocol.

Any term used in this Protocol that is defined in the Regulation or the NMA has the same meaning as in the Regulation or the NMA. In addition, any reference to Greenhouse Nutrient Feedwater (GNF) includes a mixture resulting from the mixing of GNF with other GNF or liquid agricultural source materials as permitted under the Regulation except where otherwise indicated in this Protocol.

Part 2 - Nutrient Units

2.1 How to Determine Nutrient Units Using the GNF Management Table for the Purposes of Regulation
2.2 How to Calculate Nutrient Units Using the Results of GNF or Test Solution Sampling and Analysis

The term "nutrient unit", means the amount of nutrients that give the fertilizer replacement value of the lower of 43 kilograms of nitrogen or 55 kilograms of phosphate as nutrient as established by reference to this Protocol. This section sets out how to determine the number of nutrient units for the purposes of this Regulation and this Protocol. There are two ways to determine nutrient units depending on the requirements in the Regulation and this Protocol as set out below in sections 2.1 and 2.2.

2.1 How to Determine Nutrient Units Using the GNF Management Table for the Purposes of Regulation

When using the GNF Management Table for the purposes of the Regulation, the instructions included in the GNF Management Table must be followed to determine the nutrient units in the GNF generated at the greenhouse operations on the farm unit. Controllers must consider their past operations, GNF generation, and changes to their operations when applying the GNF Management Table.

2.2 How to Calculate Nutrient Units Using the Results of GNF or Test Solution Sampling and Analysis

This section sets out how to calculate the number of nutrient units in GNF for the purposes of the Regulation when the GNF or test solution has been sampled and analyzed in accordance with this Regulation.

The number of nutrient units (NU) to be used for the purposes of the Regulation is the greater of the nitrogen NU and phosphorous NU calculated in accordance with the equations below:

  • Nitrogen NU = volume of GNF generated (m3) in a calendar year * PAN (plant available nitrogen) (mg/l) /1000 /43 (kg/NU) of the GNF
  • Phosphorus NU = volume of GNF generated (m3) in a calendar year * PAP (plant available phosphate) (mg/l) /1000 /55 (kg /NU) of the GNF
2.2.1 Determination of the Annual Volume of GNF Generated for the Purposes of the Equation in Section 2.2

For the purposes of paragraph 2 of subsection 18(1), paragraph 2 of section 19, row 3 column 1 of subsection 21(3), paragraph 1 of subsection 22(2) and subsection 24(2) of the Regulation, when determining the volume of GNF for the equation in section 2.2, the term "volume of GNF generated in a calendar year" in the equation refers to the actual volume of GNF generated in that calendar year.

2.2.2 Determination of the Concentration of Nutrients for the Purposes of the Equation in Section 2.2

For the purposes of the equation in section 2.2 of this Protocol and for paragraph 4 of subsection 43(2), and subsections 64(2), and 66(1) of the Regulation, the concentration of PAN, PAP and PAK (plant available potash) in GNF must be determined.

Concentrations of PAN, PAP and PAK in GNF must be determined using results from the sampling and analysis of GNF or test solution. The concentrations must be calculated in accordance with the equations below:

  • PAN (mg/l) = (ammonia-N +ammonium-N) + (nitrate-N + nitrite-N) + (0.3 * (Organic-N))
    • Organic-N = (Total Kjeldahl nitrogen - (ammonia + ammonium-N))
  • PAP (mg/l) = total phosphorous * 2.29
  • PAK (mg/l) = total potassium * 1.2

Part 10 - Land Application Requirements

10.1 Determination of Percentage of Crop Residue
10.2 Procedures for Determining Unsaturated Soil Conditions
10.3 Maximum 24-hour Application Rate

10.1 Determination of Percentage of Crop Residue

For the purpose of subsection 3(4) of the Regulation, the method for determining the percentage of land covered by crop residue is as follows:

Rope transect method:

  • The material required is a light rope (about 8 m in length with knots or other markings spaced along the rope at 15 cm intervals so that there is a total of 50 knots. This rope is laid out across the soil surface, preferably at an angle to the crop rows, and pulled slightly taut. The number of knots that are touching pieces of crop residue (the crop residue being touched has to have minimum dimensions of 2 mm by 2.5 cm) is counted. This number, when multiplied by two, is the per cent crop residue cover. This determination must be made a minimum of four times in different parts of the GNF application area, and the results averaged.

10.2 Procedures for Determining Unsaturated Soil Conditions

For the purpose of the definition of "unsaturated soil" in subsection 3(1) of the Regulation, use the following test to determine whether or not the soil has a water content that is less than 100 per cent of the total pore space or is at a negative soil water pressure:

  • dig a hole or remove a soil core to the minimum required depth for the purposes of the Regulation; and
  • observe whether water flows into the hole from the surrounding soil (this may take up to 30 minutes for most hydrologic soil groups but up to 60 minutes for hydrologic group D soils.

10.3 Maximum 24-hour Application Rate

The following sets out the procedure that must be used to determine the 24-hour maximum application rate referred to in paragraph 2 of subsection 39(1) of the Regulation. This 24-hour maximum application rate must be determined using a soil moisture instrument (e.g. tensiometer) to determine the actual per cent water by volume that is representative of the areas of the field to which GNF is applied. The user must then determine the maximum application rate by calculating the difference between the actual per cent water by volume and the field capacity for this soil texture for the GNF application area as determined using the Soil Moisture Field Capacity Table below. This number is then multiplied by 30.

Calculation: (Field Capacity value from the Soil Moisture Field Capacity Table (Table 2 below) - measured moisture value) x 30 cm x 100 m3/cm per ha = application rate in m3/ha/24 hour period.

Note: the 100 factor is used to convert cm to m and translate to a hectare basis (i.e. 0.01 m/cm * 10,000 m2/ha = 100 m3/cm per ha)

Example:

If the actual measured water content of a sandy loam soil is 10%:

The available capacity is calculated as:
(0.25 - 0.10) x 30 cm x 100 m3/cm/ha = 450 m3/ha

And the maximum 24-hour application rate in this case would be 250 m3/ha due to the upper limit referred to in section 39 of the regulation.

Part 11 - Contingency Planning

11.1 General
11.2 Contingency Situations

Subsections 20(1), and 26(1) of the Regulation, require the preparation of a contingency plan which forms part of the GNF strategy or plan. The contingency plan must comply with the requirements in this Part.

11.1 General

Contingency plans must list the contacts and their contact information, equipment and other resources that would be available should a contingency event occur, including:

  1. the controller(s) of the agricultural operation(s) (who can authorize expenditures);
  2. the up-to-date number for the Spills Action Centre: (1-800-268-6060);
  3. the local municipality;
  4. people renting or willing to lend equipment who are located close by; and
  5. equipment such as loader tractors and emergency storage facilities or trailers.

After an event occurs that requires that a contingency plan be put into effect, the controller(s) of the agricultural operation(s) to which the contingency plan applies must evaluate the plan to determine if improvements are needed and, if so, changes must be made accordingly by the controller(s) to prevent a similar event occurring in the future.

11.2 Contingency Situations

The contingency plan shall set out a proposal for dealing with the following types of situations:

  1. an excess of GNF, if the amount of GNF at a farm unit would exceed the available storage capacity;
  2. unanticipated releases of GNF from storage or during transportation or application;
  3. an inability to store, land apply or otherwise use GNF as otherwise provided for by a GNF strategy or GNF plan, as a result of weather conditions or unavailability of equipment; or
  4. any other contingency requiring the handling or storage of GNF in an emergency.

The preferred solution in some contingency situations may be to apply the GNF on agricultural land in accordance with the Regulation. If the GNF cannot be applied to the land of the farm unit in compliance with this Regulation, the controller must be prepared to set up alternate uses for the GNF.

In addition, controllers may consider other disposal methods such as a sewage treatment plant, disposal with the appropriate approvals or other processing methods.

The contingency plan must also include how to accomplish the items listed in items 11.2.1 and 11.2.2 below.

11.2.1 To Stop an Unanticipated Release
  1. Immediately stop the cause of the spill if possible;
  2. Shut down the appropriate pumps and valves; and
  3. Ensure the system cannot be restarted.
11.2.2 To Contain the Unanticipated Release
  1. Minimize opportunity for GNF to enter tile drain or plug the tile in the event flow appears to be contaminating the tile drains;
  2. If the spill is moving over the ground surface, an earthen berm should be built with farm or commercial equipment, such as backhoes or dump trucks; and
  3. Notify downstream users.
