Your title is misleading, I guess it should be Bitcoin's use in Agriculture industry. You should remove the word "vs" since it sounds like you're pitting a completely two different things - which looks absurd to me.
To answer your question, you should first have enough knowledge about bitcoin and how it works. It won't be an overnight process, but it would be worth it if you'll dive deep into understanding its nature. After gathering enough knowledge and information about btc, you can share it to your farmers and business partners. Educate them about it and slowly, invest on bitcoin. Set up a limit depending on your risk appetite. Maybe after that, you can also consider accepting bitcoin as payment in exchange for your raw goods.
