Field visit to grapes in Liaoning Province

IPNI China director Dr. Ping He visited grape field experiments in Yingkou, Liaoning Province with cooperators from different research institutions and universities. Nutrient omission plots of N, P and K and N application rate experiments were conducted in the field in Yingkou. Nutrient uptake and yield responses to N, P and K will be obtained from these field experiments to develop Nutrient Expert for grapes in China. This work is part of the National Research and Development Program "Fertilizer Recommendation Approach and Nutrient Directives," led by Dr. He as the chief scientist.
