it takes nature 500 years to produce one inch of nutritious topsoil. in order to maintain and replenish this important resource a diversity of plant, fungal, and bacterial life is essential. conventional farming practices using artificial fertilizers and pesticides to produce monocultures, strip the land of its natural diversity and degrade the soil faster than it can naturally replenish itself. all edibles accelerates the soil replenishment process by planting diverse organic gardens, introducing active root structures to loosen and add nutrients to soil that has degraded beneath a monoculture of lawn. also, all garden waste is composted and added back to the next season's garden, increasing soil nutrients. over time, our diverse, seasonally rotated gardens build top soil rater than deplete it.
