Barriers to adoption
Converting to CA needs higher management skills

The first years might be are difficult for the farmers, they
require training and support: – from other farmers (assoc.)
and extension services.
financial support:- (incentives, subsidies) to invest in new
machinery, no-till planters.

Necessary technologies are often unavailable (no till
planters, herbicides and chemical spray equipment)

Most farmers cannot take the risk to invest in CA (yield)

Machinery dealers might not wish to promote CA (smaller
tractors, high machinery standards and low farmer
demand)
Thank you

  • 23. Barriers to adoption Converting to CA needs higher management skills The first years might be are difficult for the farmers, they require training and support: – from other farmers (assoc.) and extension services. financial support:- (incentives, subsidies) to invest in new machinery, no-till planters. Necessary technologies are often unavailable (no till planters, herbicides and chemical spray equipment) Most farmers cannot take the risk to invest in CA (yield) Machinery dealers might not wish to promote CA (smaller tractors, high machinery standards and low farmer demand)
