There is a significant amount of soy protein in fish food as well.
Wood adhesives made with soy are used to make laminated plywood, finger-jointed lumber and particle board. Non- food industries use a number of soy products in automobile upholstery applications as well.
The discovery of soy bio-diesel is not only a great invention but is also blessing in disguise for our environment. Diesel engines run on bio diesel fuel that is prepared using soybean oil. The removal of glycerine from soy oil results in the residue or the soy biodiesel. Non–toxic and renewable, soy biodiesel is way better compared to petroleum diesel oil.
The environment friendly solvent, capable of cleansing shorelines and streams from oil or other impurities is also made from soy oil. This solvent is absolutely safe for humans and animals as well.

Soya plants can grow in many types of soils. These plants grow best in rich alluvial soil that is moist at the same time.
Soybean plants enrich the soil by nitrogen fixation. Nitrogen fixation is a mutually beneficial process in which the plant and bacteria depend on each other. As such the bacterium accumulates the atmospheric nitrogen and supplies it to the plant. It is therefore recommended to mix the particular type of bacteria with the soybean plant just before planting.
Soya pants begin to bloom by the months of July, August and September. The flowers are recognized to be white or rich violet in color.

The function of combines is to collect and arrange the soybeans in a tank that is generally found at the back of the machine. There is header in the front part of the machine that is responsible for cutting and collecting the soybeans. Hereafter, the combine removes the attached pods and stems from the actual beans and deposits them into the machine’s tank.
