EVON Bio-intensive Methods:
How to prepare beds, plant trees, & prepare bio-pesticides
Here is a list of useful handouts and other information we have prepared over the past three years based on our research results. You
can make the treatments yourself from local materials.
1. IMPROVING SOIL FERTILITY
- OUR BEST YIELDS are with Nepali Biointensive Sheet Composting, an easy way to prepare a rich bed for vegetables. Our research shows that sheet composted beds produce 1.1 to 1.5 times MORE than chemical fertilizer:
- Liquid nutrients for plants and soil -- Gitimal. Soil benefits from adding fermented plant juice.
Healthy soil requires health microbes and fungus. This mixture will increase activity.
- How to make a 2 foot deep bed (similar to double digging)
Making a 2 ft deep bed is labor intensive, but is good for deep root crops like tomatoes and asparagus. For most vegetable crops we recommend a 4 inch deep bed (sheet composting above).
- Strong roots produce a strong plant if they have healthy soil to grow. Notice that tomato roots go much deeper than others. This is a reason to prepare a 2 foot deep bed for tomatoes.
- Urine as Fertilizer. Cow and human urine are good fertilizers.
How to collect and use urine for fertilizer
Organic bio-intensive sheet composted beds produce more than chemical fertilizer. Here are the results of our three year research project.
- How to plant and manage fruit and nut trees: VERY IMPORTANT! Good planting means good production.
Planting a tree is an investment for future income. If you follow instructions, you will get good results.
3. INSECT AND DISEASE MANAGEMENT
- Kumre Kira (White Grub) control
White grubs are very difficult to control. Hand picking is effective. Light trapping stops theadult beetles from reproducing. A small CFL (or other) bulb is suspended over a basin of water with a small amount of vegetable oil. Beetles are attracted to the light, fall in the water
and die. It also catches some moths. In one night we sometimes catch more than 100 beetles in one basin.
We have tried Metarhizium Anisoplaea with uncertain results, and nematodes are also inconclusive. Other treatments like ketuke (agave) and neem products were not effective.
