The Oil Tree With Multiple Benefits
In farm systems using Derris Indica, Using 15% of the land for Derris Indica, approximately 10 tons of mulch could be produced per acre per year, 210 kg N/ha, 12 kgK/ha,80kgP/ha

 
 
In an integrated farmingSystem Derris Indica can partorm following function*
  • Providing fertility to other plants in the ecosystem by dropping their organic matter
  • The pruning used as an on-ste source of mulch and fertilizer for crops
  • *Pioneering* harsh, damaged, or open areas, boosting fertility and moderating harsh conditions
  • To increase fertility and organs matter in a low-fertility area prior to planting
  • Stablizing soil with an extensive root system
  • To help prevent erosion Serving other roles and making other connections In a diverse ecosystem
  • To provide animal fodder, shade, Windbreaker
 
Advantages of D.Indica Plantations
In an integrated farmingSystem Derris Indica can partorm following function*
  • Food for fules - D, indica can be grown on marginal lands and produces stock food at the same time as producing fuel
  • Even if it is grown on existing crop lands, it will increase the over all food production of the land.
  • Climatically suited
  • Legu me
  • Deep tap root sources water and nutrients well down in subsoil - droughtresistant,
  • Can make good use of avialable deep nutrients.
  • Oils production for biodiesel
  • Carbon sequestration via:
  • tree growth
  • soil carbon increase due to nodulation and root growth
  • displacement when in production at year 4 of fossil fuels and beyond for a further 100 years;
  • replacement of petroleum based fertilisers.
  • Produces its own nitrogen there by displacing approx 110 - 1100 kg per hectare/ pa of nitrates applied as compound fertiliser.
  • Decreased requirement of fertilisers and reduction of cultivation results in lessening of protential soil a
  • And chemical runoff into the rivers and streams.
  • Fungicidal and insecticidal action decrease pest attack
  • Can be mechincally harvested.
  • Management to assist fire control
  • Cattle grazing in well established plantations with higher stocking rates and better quality pastures due to nitrogen fixation
  • Possibility direct use of oil in modified engines.
 
 
D. Indica as a source of biodiesel ...
As D. Indtca has a high oil content (approx. 40%) and can grow on malnourished soils with low levels of nitrogen and high levels of salt, it is fast becoming the focus of a number of biodiesel research programs. Some of the advantages of D. Indica are; a higher recovery and quality of oil than other crops* no direct competition with food crops as it is a non-edible source of fuel, and no direct competition with existing farmland as It can be grown on degraded and marginal land. As a legume it is also able to fix its own nitrogen from the soil, minimizing the need for added fertilizers* Whilst there are marked advantages In the use of D- Indtca for biodiesel many considerations are needed in addressing the world's complex energy situation.
 
DERRIS INDICA FUEL PROPERTIES
  • specific gravity is 0.92
  • kinametic viscosity @ 40C, 7.53
  • flash point 90C
  • sulfur contents wt% 0.0084
  • pour point -6C
  • cloud point 4C
  • distillation (initial boiling point) 215
  • cetane number 53
 
Carbon Credit
D. Indica oil has been taken directly from the atmosphere as the tree growson average, one hectare (2.47 acres) of D. Indica absorbs 30 tons of carbon per year.Thus burning D. Indica oil instead of fossil fuels has the overall effect of reducing carbon dioxide emissions by about 75 percent and carbon monoxide emissions by almost 50 percent So planting millions of acres fn D. Indica may even help slow global warming.
