Thanks to the cooperation of Galldorf Zrt. / Euralis Kft. / Hechta Kft., which started in 2019, Rizoliq Top S soil inoculant, which has been successfully applied worldwide on 12 million hectares, has become available to our soybean varieties. Rhizobium japonicum is able to bind atmospheric nitrogen specifically in symbiosis with soy. Nitrogen fixation itself is a series of complex biochemical processes during which nitrogen molecules in the air are “bound” in the root nodules, or more precisely reduced to ammonia, which in this form can now be used as a source of nitrogen for the host plant. The amount of atmospheric nitrogen fixed in this way is very significant. Most of it nourishes the soybean, and some of it is used in the soil, in the follow-up crop. It is common practical experience that winter cereals following soybeans make good use of the nitrogen “left behind” by the soybean.
Argentina is one of the ancestral countries of soybean production and it is here that Rizobacter (www.rizobacter.com) was founded in 1977, a company which is today the world leader in soybean inoculants. This company now sells biological bacteria products for 12 million hectares in more than 30 countries around the world. Rizobacter’s product Rizoliq Top S can be applied to the seed before the seeds are bagged, thanks to the fact that the product is made up of two parts. One part of the product is the bacterial preparation itself and the other part is a special additive that protects the bacteria and keeps them alive on the seed surface for a long time. The two substances are applied together to the seed surface at the seed factory. Rizoliq Top S contains two highly effective and resistant strains of nitrogen fixing bacteria to maximize biological nitrogen fixation. The inoculant contains the bacteria at a high, 1×1010 concentration. Soybean seeds treated with Rizoliq Top S bacteria are available in bagged packs and some soybean varieties from Euralis can be purchased with it.
