Culture must be built in the first place. That is, fieldwork should be done. Where farmers are, you can be convinced by extension classes. Most importantly, on the farm, you need to be trained to see clearly

Practical fields demonstration. you need to show them the response. thus they will believe you. Otherwise, they need quick response and high yield without caring about harmful effects over human health and environment.

Field school methodology can offer a practical way to understand and appreciate the benefits of organic fertilizers. Through this process you can develop learning strategies by doing with a constructivist approach. The central point of the process will be to define a roadmap that allows developing the desired competencies for that purpose.

In developing countries, mostly the local farmers are uneducated and unaware of what is best for their crops and field soil. In my openion it is better to arrange farmer school system village by village and educate them the better practical way of using organic fertilizers

بالإمكان إقامة ورشات تعليمية تبرز من خلالها أهمية استخدام الأسمدة وطرق إضافتها المحاصيل والأوقات المناسبة للإضافة حسب حاجة المحصول

In Argentina (my country), the National Institute of Agricultural Technology (INTA) plays an extraordinary role in providing free advice to farmers and ranchers. Due to this, Argentina is a pioneer in the implementation of new technologies. However, it is necessary to clarify that the educational level of farmers and ranchers is important. This Institute has been the key in the development of precision agriculture and the genetic improvement of our cattle.This has been achieved with permanent advice through free training courses.

Thanks for the answer

Four main steps were conducted to achieve practical agricultural communication with farmers:

1) analyze and synthesize SCK(Scientific Knowledge) regarding climate mitigation agriculture;

2) undertake a community contexts survey including background data, agricultural activities,:

3) preparation of communication including a leading farmer group and agricultural knowledge for communication;

4) participatory communication interventions. During the interventions, the agricultural practices, community communication, social capital, and social support of each area were considered for communication design and practice.

Organize 'Result Demonstration' in farmers' field to show the farmers' the superiority of organic fertilizers over the chemical fertlizers. Two plots have to be taken one is experimental plot where organic fertilizers will be used and another plot of chemical fertilizers(control plot). Two plots will be alike in all its characteristics (size, fertility level, etc.). After completion of the process farmers' will be able to understand by comparing the result. This is the method in a nutshell. If required other things can be discussed later on.

Here in Brazil there is a lot of farms, specially in Minas Gerais here I live, and the best way to persuade farmers is letting they see the benefits (for the land and the economic benefits), in today's society there is a huge search for a more "organic" lifestyle, we see more people in social media advertising these type of products, if your farm use only organic fertilizes you will achieve a new niche, you can use this as an argument.

The best communication methods to persuade farmers to use organic fertilizers train the farmer for using organic fertilizers. Organize work shops, demonstrations and field trials.
