Accomplishments
Coordination of multidisciplinary research & technology transfer:
1. The ASA/CSSA/SSSA Precision Agriculture Working Group was created to update tri-society members regarding activities of NCR-180 committee members. The function of this ad hoc group has been taken over by a more formal relationship with Division A-8, Integrated Agricultural Systems. Members of NCR-180 have served as past-chair and current chair of A-8. Division A-8 sponsored or co-sponsored these symposia in 2003:
a. Sponsored
i. Variable N management of field crops--Nine presentations
ii. Precision Farming: Management of low-yielding areas in production fields--Six presentations
b. Co-sponsored
i. The role of remote sensing products in creation of management zones--Sixteen presentations
ii. Are management zones useful and practical in precision agriculture--Three presentations
iii. Management zones for agronomical and environmental management--Six presentations
2. NCR-180 members organized several initiatives within the American Society of Agricultural Engineers (ASAE). At the 2003 ASAE Annual Meetings in Las Vegas, NV, 95 precision agriculture-related papers were presented in these categories:
a. Remote sensing/imaging
i. Hyperspectral and Multispectral Imaging
ii. Vision Systems for Precision Agriculture
iii. Remote Sensing for Precision Agriculture - Parts 1-3
b. Sensors
i. Recent Advances in Instrumentation and Control
ii. Performance of Crop Yield Monitors for Precision Agriculture
iii. Soil Sensors in Precision Farming
c. Applications of Geophysical Methods in Agriculture (ground penetrating radar, electromagnetic induction, resistivity. etc.) - Parts 1 and 2
d. Variable Rate Technology to Support Precision Agriculture
e. Performance and Accuracy of GPS-Based Systems
f. Automated Guidance of Agricultural and Off-Highway Equipment
g. Using Precision Agricultural Technologies for Management Decision-Making
h. Educational Methodologies and New Technologies in Precision Agriculture
3. NCR-180 members are in the process of organizing the biennial International Preci-sion Agriculture Conference held in Minneapolis, MN. In 2002, 600 registrants heard more than 200 technical papers and posters in concurrent sessions on natural resource variability, management systems, management for crop quality, new applications from around the world, statistics, geostatistics, sampling, modeling, technology/sensors, technology/guidance systems, technology/yield monitoring, applications of remote sensing to precision agriculture, remote sensing/nitrogen management, remote sensing/pest detection and management, information management, profitability, environment, and technology transfer and curriculum.
