Detailed explanation-1: -Notes: Double digging is a gardening technique used to increase soil drainage and aeration. It involves the loosening of two layers of soil, and the addition of organic matter. Double-digging is a key component of the biodynamic method of cultivation.
Detailed explanation-2: -Double digging is a useful way of cultivating soil in new gardens and in situations where deep topsoil is required.
Detailed explanation-3: -Biointensive agriculture is a sustainable organic farming system based on working with the basic elements needed for life – soil, water, air and sun – to achieve maximum yields, while increasing biodiversity and soil fertility.
Detailed explanation-4: -Well loosened soil increases air and water availability to plant roots and helps access nutrients stored deeper in the soil. When done properly, double-digging can actually enhance the soil environment, and even support microbes and mycorrhizal threads that feed root systems by providing the air they need.
Detailed explanation-5: -Deep soil preparation. Close plant spacing. Composting. Carbon farming. Calorie farming. Companion planting. Planting open-pollinated seeds. Keeping a whole system perspective.
