Visits of wheat and barley experiments at western and southeastern Buenos Aires
On November 12-13, and 18-19, Dr. Garcia visited with staff of ASP, farmers, and local agronomists the wheat and barley experiments included in the Research Project ARG-27 "Long-term Nutrient Management Network for Southern Buenos Aires Province". Despite of the effects of the severe drought registered in the region during 2008, the development of crops in several sites were considered good and nutrient responses were evident. Responses to N and P were detected at all sites. Visual responses to S were detected at 3 of 6 sites.
It has been interesting to interact with farmers and agronomists in the fields where clear visual responses to P in soils of P Bray levels ranging from 8 to 16 ppm were observed. It has been an excellent educational process in a year in which farmers hesitated in applying P because of high fertilizer prices.
These experiments will be harvested on December 2008 and double cropped soybeans will be planted.
