• Dynamic Accumulators -- we can manipulate the content of certain nutrients in finished compost by adding larger quantities of local plants that are known to be high in those nutrients. For example, to make a compost high in phosphorous, we may focus on additions of mustards, buckwheat, alfalfa, walnut husk, corn, sunflowers, marigolds. This technique is especially important for addressing nutrient deficiencies in remote areas that do not have access to purchased materials like pina, bonemeal, and other organic fertilizers. We are currently investigating the nutrient value of local weeds for this purpose.

  • SRI Rice (System of Rice Intensification) -- SRI Rice differs from the traditional Nepali method of growing rice, which usually transplants 4-5 seedlings in one hole, and keeps the terrace flooded. SRI Rice is grown with only one seedling per hole with 8-14 day old seedlings, and irrigated intermittently instead of flooding, with seedlings transplanted slightly farther, about 25-30cm apart.

  • EVON's Soil & Materials Nutrient Analysis -- See the lab analysis data for pina, wood ash, bonemeal, and compost samples taken at EVON, as well as our general soil characteristics from samples taken in 2014.

  • EVON's 3-year Yield Comparison Study -- Compared between five treatments of 1) sheet-composting; 2) 1-ft double-digging; 3) 2-ft double-digging; 4) Nepali traditional; and 5) chemical fertilizer. Funded by the Dzi Foundation through the ZORO project. Overall yields were highest in the biointensive sheet-composted beds, and lowest in the traditional Nepali-style beds.
