Site-specific Management of Potatoes

This project is investigating the potential for site-specific management to improve yields of irrigated potatoes. Tissue concentrations of P and K can be quite variable.

IPNI-1996-CAN-AB14

Potatoes are a high value crop with high input requirements. Yields in southern Alberta average 22 tons per acre, but vary considerably within fields, making potatoes an excellent candidate for precision farming techniques. This project is investigating the potential for site-specific management to improve yields of irrigated potatoes in two farm fields. Read more

Interpretive Summary

Site-Specific Management of Potatoes, 1999 This completed project evaluated the use of yield monitoring technology and global positioning systems (GPS) to determine optimal fertility management of irrigated potato production in southern Alberta. The variability in potato yield was compared to soil and petiole samples collected through the growing season and geo-referenced with a portable GPS.

Site-Specific Management of Potatoes, 1998 This project, now in its third year, is investigating the use of global positioning system (GPS) technology and yield monitoring in irrigated potato production in southern Alberta. Improving fertilizer management is a key part of the study. Yield maps are demonstrating how variable potato yields may be, and GPS has allowed soil and petiole concentrations of N, P and K to be intensively monitored.

Site-Specific Management of Potatoes, 1997 This project is evaluating site-specific nutrient management of irrigated potatoes. Two fields have been yield monitored since 1996 and grid sampled for soil and plant tissue nutrients. Results are showing irrigated potato production can be highly variable making it a good candidate for more precise nutrient management. Variable rate N application increased yields by 17 percent in one field.

Site-Specific Management of Potatoes, 1996 Potatoes are a high value crop with high input requirements. Yields in southern Alberta average 22 tons per acre, but vary considerably within fields, making potatoes an excellent candidate for precision farming techniques. This project is investigating the potential for site-specific management to improve yields of irrigated potatoes in two farm fields.
