    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 ft2.)

    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)

    P205 Crop Removal Maximum Rate
    (L or tonne / hectare)

    [(P2O5 Crop 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.

    Stop 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)

    P205 Crop Removal Maximum Rate (gallons or tons/acre)

    [(P2O5 Crop 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

    ______ 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.

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