Dear David,

One question to ask you. I understand that farming/cropping  systems agronomy is about the rationales and approaches in planning/designing on-farm or regional crop composition & distribution, intercropping, crop rotation, sequential cropping, nutrient management, water management, soil management/tillage, residue management and other relevant practices at regional/farm level. Am I right? or what's your understanding to farming/cropping  systems agronomy? Thanks.

All the best

Weili

Dear Weili
 
I do not see any problem with your definition or understanding but I cannot recall seeing a formal definition of cropping systems agronomy.  I probably in the spirit of the evolution of the farming systems approach would include an additional statement that suggests participation  of farmers to ensure that improvements proposed incorporate their knowledge and are compatible with their resources, skills goals and interests.  Also such improvements need to be equitable and sustainable from a societal viewpoint (see the lectures I gave in China).
 
All the best

Dear David,

Thanks for your suggestion. I now realize that there should be two parts in systems agronomy: the 'hard' part consisting of the issues I mentioned last time and the 'soft' part consisting of the rationale and approaches ensuring the relevance of the improved agronomic practices.

Wish you and Shirley a pleasant X’mas season!

Weili and family
