Predicting Nutrient Application

at CAFO Land Application Fields using CAFOweb™

Waste to Worth Conference April 2-5, 2013

Why CAFOweb™? Nutrients from manure solids and/or

green water can leach into the ground water if not applied at agronomic rates

Current Best Management Practices do not allow predictive management of nutrients

CAFO operator knows only at the end of the year if nutrients were applied at agronomic rates

Typical Dairy Process Water Flow

Over applied fields 2006

Over applied fields 2007

Purpose: Which field do I apply to?

?

One-stop, Real-time Tool Glorieta Geoscience, Inc. designed

CAFOweb™ software to implement CNMPs and predict nutrient application rates and timing

Beta tested at 8 dairies in New Mexico and Nevada 25,000 cows 2600 acres of land application fields

Access your data anywhere from your laptop, tablet or smartphone.

Conclusion CAFOweb™ is a one-stop, record-keeping and

nutrient management tool Real-time nutrient application data allows the

CAFO operator to make informed decisions Maintaining good ground water quality and

soil health retains the value of the CAFO facility for future generations

Informed decision lead to optimal use at the CAFO, insuring “wastes” are converted to assets or worth

Future of CAFOweb™

Expansion to other markets Integrated comprehensive water rights

module Sustainable nutrient management

across all livestock Work with NRCS to make CAFOweb™

their CNMP implementation tool
