The key in agric from my own personal findings are patience and practise.
No matter how much knowledge you have on paper or from an agric blog or classroom.
If you haven’t tried it out in a real farm, A farmer in the village is still a better farmer than you.
Every amount of knowledge without practise in agric is useless so far as the system is concerned.
The secret is in starting small.
Use it to test seeds, the market, agric practises and several before graduating to one hectare or more
