We also visited with Embrapa soybean breeding and learned that disease and nematode resistance are key issues here. They have a public/private breeding partnerships that allow them to develop soybean varieties adapted to this area of Brazil. We saw evidence of soybean rust on some lines but they have developed some resistant lines.
Visited a crop/livestock forest integrated systems research trial. They start with soybeans planted with wide (22m) rows of Eucalyptus trees. Then they grow a crop of sorghum between the trees and then follow with a crop of a warm season forage grass called Brachiaria. Cattle then graze the forage grass as the trees grow. The 9 year old trees were about 80 feet tall- eventually they can be harvested for pulpwood or lumber.
On the way back to the hotel we visited the Brazilian White House area and took a few pictures of the architecture.
