Nothing artificial. Just grow your plants and get the harvest. No fertilizer. No pest controlling. No chemicals. No traps. No watering. Don't kill any living creature. Just let them grow. Let them grow as they grow up in the forest. So that it's not agriculture right? Well, you plant what's necessary in your land. And the plants are growing up like it's growing up in the forest. This is an ancient methodology. Comes from the teachings done by the farther to son. Except the modern world wide used Gregorian Calendar, in Sri Lanka, there's an ancient Calendar. That too has 12 months specified in it. The ancient Calendar is counting by the Sun's location, moon's location and star constellations. Well, Sun and these constellations hardly moves right? Well, yes indeed. But the calculations done in the Sri Lankan ancient calendar has made the assumption that the earth is static.
