Guide to Completing the Workbook - Sections A to S

The workbook is a tool that simulates the NMAN Software.

This workbook is organized in sections, from A to S, with each line of the Worksheet corresponding to the detailed descriptions found here help you develop the required information.

Section R - Useable Acres/Hectares

Calculate the number of usable acres in each field by deducting the acreage in any setback areas from wells, surface water, or residences from the total tillable area of each field. (Note 1 hectare is 10,000 m² and 1 acre is 43,560 ft^2.)

Section S - Maximum Rates

This section double checks to ensure that no "stops" have been triggered in the completion of the field worksheet. Complete this section after all other sections have been completed to ensure that all cautions and environmental limits have been considered.

Metric

Maximum Liquid Loading Rate	________________________________ (L/hectare)	(From section B)
N Crop Removal Maximum Rate (L or tonne / hectare)	[(N Crop Removal - Line J)+ 17 kg/ha] divided by Available N (kg/1000L) x 1000 =__________________ or (kg/tonne) = __________________	(From section M)
P₂0₅Crop Removal Maximum Rate (L or tonne / hectare)	[(P₂O₅Crop Removal - Line J) + 78 kg/ha or 191 kg/ha or 303 kg/ha] divided by Available P₂0₅ (kg/1000L or kg/tonne) x 1000 =______________	(From section M)
Nitrogen Index Maximum Rate	Maximum allowable application rate only if N-Index is required______________________ (kg/ha)	(From section O)
Minimum Separation Distance Rate (for P-Index Value)	______ No application (P-Index is greater than 50) ______ Application to Crop Removal Rate ______ No P-Index Restriction	(From section Q)

The Maximum Allowable Application Rate will be the lowest rate of the above numbers. Write this number in section B on the worksheet summary.

If the planned rate is higher than the Maximum Allowable Application Rate.

Imperial

Maximum Liquid Loading Rate	________________________________ (gallons/acre)	(From section B)
N Crop Removal Maximum Rate (gallons or tons/acre)	[(N Crop Removal - Line J) + 15 lb/ac] divided by Available N (lbs/1000 gal) x 1000 =__________________ or (lbs/ton) = _________________	(From section M)
P₂0₅Crop Removal Maximum Rate (gallons or tons/acre)	[(P₂O₅Crop Removal - Line J) + 70 lb/ac or 170 lb/ac or 270 lb/ac] divided by Available P₂0₅ [(lb/1000 gal) or (lb/ton)] x 1000 =______________	(From section M)
Nitrogen Index Maximum Rate	Maximum allowable application rate only if N-Index is required______________________ (gal/ac)	(From section O)
Minimum Separation Distance Rate (for P-Index Value)	______ No application (P-Index is greater than 50) ______ Application to Crop Removal Rate ______ No P-Index Restriction	(From section Q)

The Maximum Allowable Application Rate will be the lowest rate of the above numbers. Write this number in section B on the worksheet summary.

If the planned rate is higher than the Maximum Allowable Application Rate.
