1. No pesticide 无杀虫剂
Pesticide not only kills all the insects in farm, but also resides inside the soil and vegetables/fruits thus create serious harm to human and environment. When absorb, it might cause harmful effect on our body or even our next generation and it reduce the biodiversity inside the soil. Continuous use of pesticide may cause pest to evolve to become resistant to pesticides, thus dosage used had to be increased. In the end, human and natural pay the bills. Instead of using pesticide, we pay focus on soil building to grow healthy and strong plant, as healthy plant will have stronger defense towards worm and bacteria attack. However when there is pest booming due to extreme weather, natural pest repellent will be introduce, such as lemongrass, marigold, enzyme and etc.
2. No herbicide 无除草剂
Weed is seen as a friend rather then enemy, it helps prevents soil erosion, holds moisture, propagates microorganism, died as organic fertilizer and improves soil ventilation. Weeding only is done when is need, for example when the weeds around the crops is covering and disturbing the growth of our crops. Tools we use for weeding is bush-cutter and hand, and then collected to build our compost pile.
3. No synthetic fertilizer 无化学肥料
Natural fertilizer such as cow dung compost, fish amino acid, eggshells, enzyme and rock mineral will serve as our fertilizer input. Compost has all nutrient need by plant, fish amino provides high amount of Nitrogen, eggshells give calcium and rock mineral provides micro nutrient. Synthetic fertilizers can result in an overabundance of nutrient, when trap in soil, it increase soil salinity and acidity. Besides, runoff of them will kill fish, degrades aquatic habitats and threatens the stream, river and sea.
4. Minimum or Zero Tillage 少/零翻土
Tilling is an activity that destroys soil structure, cause the death or disruption to the habitat of micro organism and small animal inside the soil. Intensive tilling even cause soil compaction, loss of organic matter and washed away of top soil. We only use tilling machine to help break the hard soil for new farming area, hoe and garden cultivator will do the best after that. This is because compost and organic matter that added to the soil will help trap air and moisture which encourage the growth of microbe in the soil. Uncountable microbes will do the soil softening job for you ever second!
5. Intercropping 间作
Intercropping is a practice that grows 2 or more crops in the same place during a same growing season. Intercropping maximize the usage of the space and sometime mix different companion crop that can help each others, an example is amaranth intercrop with corn/bean/okra, amaranth maturity period is 1 month while corn/bean/okra maturity period is 2 months or more. Amaranths are harvested as corn/bean/okra just getting established. Another example is shade tolerate plant like chilly paddy intercrop with papaya tree. Marigolds/lemongrass was plant along with crop as it can repel some pest as well as attract beneficial insect.
6. Crop rotation 轮作
Crop rotations assist in breaking life cycles of insects, pests, fungi and bacterial, thus minimize the harm caused by them. Besides, crops are rotated through the fields to replace nutrients in the soil.
7. Encouraging useful predator/beneficial insects 鼓励益虫/天敌的生长
We encourage beneficial insects, by providing suitable living conditions, as a strategy of pest repellent. We have a huge area of wild jungle for the animals, birds, snakes, insects to habit in. Besides, we create few ponds as frog habitat. For example, birds and frog eat small insects, snakes eat rats, certain ladybird eat aphid, lizard eat off butterfly, assassins bug kill of almost all kind of worm. A little effort to create the environment and some patience pays off to wait for beneficial insects/natural predators to restore ecology balance will keep pests down to minimum level.
