2. & 3. Legume usage and Companion planting
2. Legume usage for nitrogen fixation
Rotate a legume through every year to add nitrogen. This is one of the biggest expenses in chemical based agriculture and can be minimized or even replaced by biological practices. Bacteria help the farmer by adding surplus nitrogen for the next crop. It finds the nitrogen in the air and captures [fixes] it in small colonies on the roots of the peanut, soybean, sitao etc. The nitrogen-fixing bacteria live in colonies on the root in small nodules.
3. Companion planting
(inter cropping) for insect control, wind blocks, soil conservation etc. - Some plants give benefits to others to help them grow. Others, like marigold, ward off insects. Tomatoes do well with carrots and stimulate growth. Onions prevent the carrot fly from infesting the root with eggs. Papaya wards of corn borers. The radish pictured above will protect other crops planted in neighboring rows. |

S.A.L.T. hedges
[Sloping Agricultural Land Technology] prevent high winds from damaging the crops and filter the wind while preventing erosion. The hedges are usually legumes but any plants can work. Planting rows follow the contour of the land and every other row is crops. |
