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.

CAFOweb™ Current Users
More than 30 CAFOs Agricultural Farms Select Milk Processing Plant NMHU golf course Taos Ski Valley snowmaking water rights

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
