2. School Branch Monitoring Project
Objective:
Document the potential for production
agriculture to complement water
resources through the implementation
of soil health management systems
3. Healthy, Productive Soils System Criteria
USDA is an equal opportunity provider and employer.www.nrcs.usda.gov
Indiana is a national leader in Soil Health!
• What does Soil Health mean?
• Soil Health Key Indicators =
• Increasing organic matter
• Improving aggregate stability
• Increasing water infiltration
• Increasing water-holding capacity
• Improving nutrient cycling
• Enhancing and diversifying soil biology
Soil Health is not a destination...it’s a Journey
4. Healthy, Productive Soils System Criteria

Mining Organic Matter
Is Not An Option!
• Each 1% of O.M.
contains:
10,000 lbs. of C
1000 lbs. of N
100 lbs. of P
100 lbs. of S

• Achieving soil health through:
• A Quality No-till (Never-Till) System
• Diverse and Strategic Cover Crops
• Adapted Nutrient Management
• Integrated Weed & Pest Management
• Diverse Crop Rotations
• Precision Farming Technology
• Prescriptive Buffers and other
Edge-of-field practices

29. Slide 30
Key Questions to be Answered:
In fields managed with long-term no-till + cover crops + precise
nutrient management + buffers:
• What is the nutrient and sediment load of this system
from the edge-of-field?
• What is the nutrient load from the edge-of-field by
switching phosphorus application rate, form, placement
and timing?
• What is the edge-of-field nutrient load from a bio-
reactor/bio-swale?
30. Slide 31
Key Questions to be Answered:
• What are the in-stream loads of nitrogen, phosphorus, and
suspended sediment in a stream reach where 40% of the upstream
cropland drainage area is managed with long-term no-till + cover
crops + precision nutrient management + buffers and the other 60%
of cropland in reduced tillage systems, compared with other reaches
of the stream?
• What are the biological community responses in reaches of the
stream that have different combinations of upstream agricultural
and residential land use?

Future Plans
Edge-of-field Monitoring
Add farmer sites to include:
• Existing tillage to no-till/strip-till
• No cover crops to Cover Crops
• Existing nutrient mgmt to various
4R principles
Conservation Practices
(current funding available through
NRCS NWQI, CREP, others)
• Increase buffers
• Increase no-till/strip-till adoption
• Increase conservation cropping
systems adoption
• Install a 2-stage ditch
