Calvin Fox combined farming and evangelism and spent a quarter of a century planting churches and helping farm families increase their yield in the Philippines. Then, in 1995 at the age of 54, he and his wife, Margaret, moved to one of the poorest and most difficult regions of India to develop a demonstration farm and training center for tribal farmers. There they brought a simple but highly effective farming method, developed in the Philippines, and adapted it for India. Sloping Agricultural Land Technology (SALT) helped farmers cultivate crops on steep, eroded hillsides. More importantly, they trained farmer-evangelists to plant the gospel among their families and villages through Bible storying and other means.
