 Nutrient Management Software
(Cornell CropWare)
Because of the complexity in accounting for all of the variables involved
in developing a workable Comprehensive Nutrient Management Plan (CNMP),
NYS NRCS, NYS Dept. of Agr. and Markets and NYS DEC, provided the
financial support for the development of the CUNMPS. This software
package is comprised of two computer programs: the Cornell Net Carbohydrate
and Protein System (CNCPS, a herd nutrition program) and Cropware
(a crop nutrient management program). The Cornell Net Carbohydrate
and Protein System (CNCPS) software enables the user to develop progressive
animal nutrition plans to maximize nitrogen (N) and phosphorus (P)
use efficiency across the herd by reducing both nutrient inputs associated
with purchased feeds and nutrient excretion from livestock. Cornell
Cropware enables the user to allocate manure and fertilizer nutrients
based on soil type, crop requirement and environmental risk indices.
The Cornell Cropware program contains equations and coefficients needed
to implement Cornell nutrient management guidelines for meeting crop
requirements with manure and inorganic fertilizer nutrients. The software
also allows for the assessments of P runoff risk, via the NYS P Index,
and N leaching loss, via the NYS N Leaching Index. Recommendations
and nutrient management plans generated using Cornell Cropware are
designed to comply with NRCS standards. For more information on CNCPS,
visit the Cornell
Nutrient Management Planning System Web Site. Access more information
on Cornell Cropware and documentation on Cornell guidelines for nutrient
management.
New York State Phosphorus Runoff Index
Cornell University faculty and staff, Cornell
Cooperative Extension field staff, agencies including NRCS and Soil
& Water Conservation Districts, private sector crop consultants
and producers have jointly developed a first draft of the New York
Phosphorus Runoff Index (NY-PI). This draft version includes transport
(soil drainage class, flooding frequency, distance to the stream and
stream type, presence or absence of concentrated flows) and source
factors (soil test P, fertilizer and manure P application rate, timing
and method). Access more information on the NY-PI and a downloadable word
document that outlines the NY-PI and Excel PI calculator.
[NOTE: The soil test conversion tools are back online!!]
In 1999, personnel from Agway Inc., Agricultural
Consulting Services Inc., ConsulAgr Inc., Cooks Consulting Services
and the Miner Institute collected 232 soil samples (0-6 or 8 inches)
in New York. These samples represented 27 soil types and eight major
agricultural soil groups from across New York. This dataset was used
to derive equations that allow for conversions of Mehlich-III soil
test data to Morgan soil test equivalents for New York soils. Independent
datasets supplied by Agricultural Consulting Services Inc. were used
to validate the conversion models and to assess the impact of the
use of such models on fertilizer recommendations for corn. Access documentation as well as a web-based conversion
tools and an excel spreadsheet version of the tools.
