Realistic Yield Expectations for North Carolina Soils
The following tables are the result of extensive data gathering and review process conducted by I\
University, the Natural Resource Conservation Service, the North Carolina Department of Agriculti
ConsurmerServices, and the North Carolina Division of Soil and Water Conservation. In 1999, cou
based representatives of each of the above -named organizations were asked to collect yield data
make a reasoned judgement of the yields for various crops on each of the soils occurring in their)
These data were collected from 87 responses, representing 93 counties. The data were then coma
with available research data and intensively reviewed by a panel of field agronomists, soil scientis,
researchers familiar with the soils, crops and climatic conditions in each region. In reviewing the c
following assumptions were made:
1. Realistic Yield Expectations should be based on the average of the best 3 years in a 5 year'
which could be achieved with a high level of management (top 20% of growers)
2. For soils that may be mapped in multiple regions or in slightly different landscapes (for exar
flood plains or stream terraces), the Realistic Yields are based, on the most common prevaili
conditions for that soil rather than the most ideal site for agricultural production.
3. For soils that are Somewhat Poorly, Poorly, or Very Poorly Drained, effective artificial draina
be in place to achieve the yields shown in the RYE tables.
4. For tobacco production in the. Piedmont physiographic, irrigation was assumed to be availab
whereas no irrigation was assumed in the Coastal Plain physiographic region. This is in acco
with numerous surveys which show less than 15% 20% of tobacco in the Coastal Plain is irr
while 70 to 80% of tobacco in the Piedmont receives some irrigation
