2. Planting method for
soil and water conservation
Growing
plants across the slope with the varions mulch (suitable
for the area) as the following method :
2.1 Planting
bushes with leguminous crops for soil maintenance Plant
bushes with leguminous crops such as horse tamarind
mixed with Mahae bean in the ratio of 1: 1. Plant it
in a row and the row space is 50 cm. Plant it as conservation
strip across the slope. The strip space is 8-10 m.
2.2 Planting
grasses strip Planting grasses strip across the
slope and the strip space is 8-10 m. Select various
grasses like Ruzi, Zettaria, Napia, Barhere and Ginny
and plant it as a strip with 1 m. width. For vetiver
grass, plant it in one row and the plant space is 5-10
cm.
2.3 Planting
mixed crops Empty area between conservation strips
is used for Planting farm crops, vegetables, flowers
and trees according to the area types. Plant mixed crops
such as planting farm crops or vegetables before planting
leguminous crops (peanut, blackbean, mung bean, Jackbean)
for rotation. Its purpose is to reclaim soil for sustainable
landuse.

|
| For
other management for soil and water conservation, there
should be soil preparation and growing plants in the rows
according to the slope area. Apply crop residue as the
mulch and soil amendmends. Planting with less soil preparation
will decrease soil erosion and it is an effective way
for landuse. |
| Soil management and chemical fertilizer application
for various plants |
Type |
Soil management |
| 1. Upland rice |
- Apply chemical fertilizer (16-20-0)
25 kg./rai before planting and add it again 6 weeks
after planting |
| 2. Corn |
- Apply chemical fertilizer (16-20-0)
25 kg./rai before planting and add fertilizer (21-0-0)
25 kg./rai after the second time of killing weeds. |
| 3.Redbean |
- Add chemical fertilizer (16-20-0)
25 kg./rai by scattering it beside the row and incorporate
it. |
| 4. Wheat |
- Add chemical fertilizer (16-20-0) 25 kg./rai before
planting |
| 5. Barley |
- Add chemical fertilizer (15-15-15)
20 kg./rai before planting and after planting 4
weeks, add Uria (46-0-0) 10 kg./rai |
| 6. Trees |
- Prepare the hole with its width,
length and depth 50-100 cm. Mix soil surface with
half of kerosine can of compost or animal manure
and chemical fertilizer (15-15-15) 200 g./hole.
Add the mixed soil at the bottom hole before planting.
Cover the plants with crops residue to retain moisture. |
| 7. Perennials |
- When the plant age is 2,4 months,
add fertilizer (8-14-3) 130 g./plant. At the plant
age of 6 months, add fertilizer 200 g./plant. For
Para-rubber, add fertilizer 400 g./plant when its
age is 23, 29, 35, 41 months. Add apply fertilizer
(13-9-4) 530 g./plant when its age is 47, 53, 59,
65 months. |
| 8. Vegetables |
- Add fertilizer (15-15-15) 40
kg./rai by dividing it to add 2 times. For cabbage,
add the first 7 days after transplanting and add
the second part 20-25 days after the first time.
For cauliflower, genus Terminalia and turnips, scatter
the fertilizer beside the rows and incorporate the
soil. |
