Masanobu Fukuoka (2 February 1913 – 16 August 2008) was a Japanese farmer and philosopher celebrated for his natural farming and re-vegetation of desertified lands. He was a proponent of no-till, no-herbicide grain cultivation farming methods traditional to many indigenous cultures, from which he created a particular method of farming, commonly referred to as "Natural Farming" or "Do-nothing Farming".
Among other contributions, Fukuoka re-invented and advanced the use of clay seed balls. Clay seeds balls were originally an ancient practice in which seeds for the next season's crops are mixed together, sometimes with humus or compost for microbial inoculants, and then are rolled within clay to form into small balls. This method is now commonly used in guerilla gardening to rapidly seed restricted or private areas.
