provide the plant with sugars needed for growth
Soybean seed is usually planted in order to enrich the soil in nitrogen before the next crop. Soybean and all legumes fix the nitrogen from the air into the soil, thanks to bacteria symbiotes who live in nodules around the soybean root.
Yes, a bacterium known as rhizobium lives inside special nodules on the roots of soybeans and other legumes. Rhizobium is able to take gaseous nitrogen from the atmosphere and turn it into an organic form, which can be use by the plant. The bacteria gets a safe place to live inside the plant and the plant gets nitrogen from the bacteria.
Nitrogen from the air is absorbed by the bacteria present in the root nodules of the plant in a symbiotic relationship in which the bacteria provide nitrogen for the soybean's growth in exchange for some nutrients (mostly sugars) that flow in the plant's roots and that the bacteria need for its own growth.
I am so thankful that I am a soybean farmer; their symbiotic relationship with Rhizobium species allows my crop to be grown with less nitrogen fertilizer input since these bacteria carry out nitrogen fixation.
Clover peas lupins.
Bacteria that exist in the root nodules of some plants can absorb nitrogen from the air in the soil. One notable example is the Rhizobia that lives in nodules on soybean roots. Similar root systems exist in clover and alfalfa.
Soybean is a cash crop and is also used in crop rotation to put nitrogen back into the soil.
soybean are leguems which can bind nitrogen to enrich the soil
nitrogen fixation
There is no chemical formula for the product soybean oil. This is because soybean oil is not a chemical but a mixture.
