By Nathan Gomori

As an organization our mission has always been to #HelpFarmersToGrow and in pursuit of that we have created several platforms dedicated to farmers of all levels. It is a place where many of our followers have become a part of a community that is dedicated to farming and agriculture. We love to see that so many of you are sharing ideas and/or seeking council from other farmers as well as our resident vaMudhumeni’s. In celebration of that spirit, we have tasked some of our vaMudhumeni’s to answer some of your questions that you may have asked in our groups or pages that may have gone unanswered, like the one below.
