We grow then just normally like any other farmer. The only difference is we don't use any chemicals or pesticides as many others use.
Our farms are 100% chemical free and use only compost, vermicompost, vermi wash, and animal manure to enrich our soil.
We make manure with our excess or leftover leafys and vegetables as vermicompost for our next crop cycle. This helps our farm soil regain enough nutrients between the crops. Also, we leave the land to heal itself after every crop cycle.
