3 24. Nutrient Management Planning BMP (Cost-share 50% up to $4,000) Objective: Assist in developing a protocol/process for nutrient application tailored to: cropping system, management and environmental risk. Soil type Crop & yield Environmental Risk (leaching, runoff) Recommendations on timing, rate and form Establish monitoring and record keeping program

4 What is a Nutrient Management Plan? The plan has 10 components (Manitoba Template): 1. Locate facilities and fields on maps 2. Identify environmentally sensitive areas 3. Specify crop rotation 4. Determine expected yields 5. Obtain results of soil, plant and manure analysis 6. Account for nutrients from all sources available on the farm 7. Develop a nutrient budget for each field 8. Make recommendations of nutrient rate, timing, form and method of application 9. Review and modify plan as needed 10. Maintain records and complete a nutrient budget

5 NMP Summary - Manitoba 471 applications approved Ave. funding/client - $3,150 ($6300 total) 5-6 companies providing >80% of the acres Typical cost per acre $4-$8/acre Manitoba Water Stewardship has an additional top-up of 25% Very Timely producers are purchasing GPS, mapping and variable rate technology, improved seeding and fertilizing placement equipment, making implementation of NMP much easier

6 NMP Summary (cont t) Many Nutrient Management Plans are part of an agronomic package that may include: Integrated Pest Management Irrigation Management Erosion Control Range of products and services dependant on cropping systems, equipment and management. Minimum criteria must be met before payment can be made.

7 NMP - Prairies Manitoba Sask. Alberta Applications (Approved/Paid) Funding $1,480,000 $603,000 $568,000

8 Manitoba Observations: Many consultants were providing products and services that met most of the required criteria. Common adjustments included: Identifying Environmental risk (leaching, runoff, buffers) Packaging all components of NMP Monitoring and Record Keeping

9 Nutrient Management Planning BMP: - allowed growers to try NMP (first time) - expand acreages/services - try new consultant/agronomist

10 Why NMP (growers)? Improved net return per acre Reduced fertilizer inputs Recommendations for decision making Time Record keeping Structure

11 14. Improved Cropping Systems: applications Activity Cost Share Maximu m Narrow openers on seeding & post seeding implements - low disturbance placement of seed & fertilizer. Chaff collectors or spreaders (existing combines) 30 % $15K Precision farming applicators: GPS to collect info., GPS guidance, controllers for variable rate fertilizer application

12 Future Opportunities/Work Economics Yields, net return/acre Environmental Benefit Improved nutrient efficiency Reduced application in sensitive areas Role of Equipment/Technology Importance of Recordkeeping for future decision-making
