Gobal Warming?

[Raven]

the mixing of biodiesel into regular diesel has the engineers

scratching their heads... only because with biodiesel it has this affinity to moisture and generally you need to start the diesel vehicles with pure diesel fuel until the motor is well warmed up and then you switch over to the biodiesel.

The origional diesel engine was designed to run on vegetable oil not the refined diesel fuel we know today. Sunflowers are another important crop for biodiesel production! One of the best other fuel sources currently being tested is making fuel from pond scum and or algae which has a phenomenal growth rate.....and it produces huge amounts of fuel as compared to corn ,soybeans or sunflower seeds.

Sunflower roots growth expressed as depth penetration and root density is greater than that of other crops such as maize, sorghum and soybean, ensuring and adequate supply of water and nutrients even with extensive farming methods.

Variations in nitrogen levels
Sunflower generally has a favourable productive response to nitrogen rates, even below 70-100 KG/hectare. This results partly from its large root system, which is important in maintaining required water and nutrient supplies. Furthermore, the main root can often reach a depth of 2 metre, enabling the plant to extract sufficient quantities of water from arid soils. (the roots can grow downwards 6 feet deep)
