It only took one year to change chemically-contaminated soil to chemically-free one. Modern nitrogen fertilizers are applied in the form of ammonium. Please enable it to take advantage of the complete set of features! Moreover, a diverse bacterial community appears to utilize sugar, suggesting that there are widespread effects of DBP contamination on soil microbial ecosystems. A recent review paper from Xinda Lu and his team looks at different roles that various soil microbes have in soil’s nitrogen cycle. (aerobic means the bacteria are of the type that need oxygen to survive.) At the same time, he found a lot of weeds until he was introduced to alternative biological microbes. Currently, biological microbes are being introduced to serve as an environmentally-friendly pesticide for Thai farmers as they were proved effective. After using them for 7 years, the microbes could completely solve problems on weeds for the entire cycle. Last year, upon the ban against 3 hazardous pesticides, namely Chlorpyrifos, Paraquat and Glyphosate, sugarcane farms in Thailand, besides those of rubber, cassava, corn, palm oil and other fruit trees, have been affected because their owners still needed to use the chemical substances. Dibutyl phthalate contamination remolded the fungal community in agro-environmental system. Under our feet, in the soil, is a wealth of microbial activity. 2020 Oct;265(Pt B):114800. doi: 10.1016/j.envpol.2020.114800. It only took one year to change chemically-contaminated soil to chemically-free one. Clipboard, Search History, and several other advanced features are temporarily unavailable.

On behalf of the researcher, Mr. Thapanarom informed that biological microbes could not be used together with any chemical substances as they are living things. In addition, a group of private researchers informed Maejo University that biological microbes were really effective for all agricultural systems, even from soil maintenance which was once dependent on chemical substances. NIH Xu W, You Y, Wang Z, Chen W, Zeng J, Zhao X, Su Y. Sci Rep. 2018 Feb 8;8(1):2605. doi: 10.1038/s41598-018-21030-8. Various mechanisms have been proposed, including cell signaling. There is some additional information, as well, that Japan, Germany, Indonesia and other countries in Europe are using biological microbes to solve problems on toxic pesticides and their government gave strong support. Researchers are studying nitrification because it can be linked to greenhouse gases and loss of fertilizer. Diverse microbes use different processes – and sometimes work together. If you find this intriguing, please do read on.  |  These bacteria could fix nitrogen, in time multiplied, and as a result released oxygen into the atmosphere. Sugar metabolism resulting in the generation of ATP and reducing agent (NADPH), as well as the expression of some key enzymes (dehydrogenases) were also upregulated by DBP treatment. Soil depth and other factors also influence microbe abundance. Molasses, a highly viscous by-product of sugar refinement, is a great supplement for improving your garden. Owned by Mr. Surin Khanthong in Nong Ma Kha Mong Village, Suphan Buri, the farm uses microbes as a major pesticide without any chemical substances. The results indicated that DBP contamination accelerated glucose consumption and upregulated the expression of porins and periplasmic monosaccharide ATP-binding cassette (ABC) transporter solute-binding proteins (SBPs). Also, its average production costs were equal to the three toxic substances already banned. Microbes comprise a world that works in synergy to create soil conducive to healthy organic agriculture. Get the latest research from NIH: According to Lu, “Soil microbes catalyze most of the transformations of soil nitrogen into plant-usable forms. In response to the concern that the microbes used to produce fertilizer and herbicide would mutate themselves and affect the ecosystem, he confirmed impossibility as the microbes are living things and cause no harm. The review was recently published in Soil Science Society of America Journal. However, the effects of DBP on agricultural microbiomes are not known. SESVanderHave offers great genetics for growers in any environment. Ensuring that the soil has plenty of oxygen is extremely important. Effect of dibutyl phthalate on microbial function diversity and enzyme activity in wheat rhizosphere and non-rhizosphere soils. Soil Microbes Need Sufficient Oxygen. NLM Epub 2020 May 16. Bioremediation of dibutyl phthalate in a simulated agricultural ecosystem by Gordonia sp. Kong X, Jin D, Jin S, Wang Z, Yin H, Xu M, Deng Y. J Hazard Mater. Follow these simple instructions to enable JavaScript in your web browser. Soil pH, temperature and the ratio of soil carbon to soil nitrogen were all compared to the number of microbes in each soil sample. Kong X, Jin D, Tai X, Yu H, Duan G, Yan X, Pan J, Song J, Deng Y. Sci Total Environ. There are many more archaea that contribute to nitrification in some soils than there are bacteria responsible for the same activity. Apparently the sugar gives soil microbes a shot in the arm, so they grow faster and compete more effectively with the plants for nutrients. Soil pH also influences how active soil microbes are in the nitrification process. You can level the playing field by supplying extra carbon, and the simplest way to do this is to add sugar. ACH Seeds continues to work closely with growers to provide what they need. According to Lu, “Soil microbes catalyze most of the transformations of soil nitrogen into plant-usable forms. Find NCBI SARS-CoV-2 literature, sequence, and clinical content: This included the abundance of microbes in soil in relation to various environmental factors. Mr. Surin said that, previously, he had used some chemical substances and had problems on rather high production cost. In this study, DBP levels in black soil were evaluated, and the impact of DBP contamination on the uptake and metabolism of sugars in microbes was assessed by glucose absorption tests, metaproteomics, metabolomics, enzyme activity assays and computational simulation analysis. This is especially true for compacted soils. To help Thai farmers, Mr. Alongkorn Polabut, the advisor to the Minister of Agriculture and Cooperatives, along with Mr. Worayuth Bunmee, the Director of the Division of Policy on Technology of Agriculture and Sustainable Agriculture, as well as public officials and representatives of private researchers who carried out a study on biological microbes at Maejo University, have recently checked a 600-Rai organic sugarcane farm. Environ Pollut. Actually, there are microbes in any soil that has habitat for them. The experimental plant plot is totally chemically-free. A much talked about question is what kind of another pesticide as effective as the already banned ones to be used. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. 2019 Jan;215:189-198. doi: 10.1016/j.chemosphere.2018.10.020. This site has features that require javascript. Epub 2018 Oct 6. Get the latest public health information from CDC: In order to be efficient at this process, microbes need oxygen. Copyright © 2020 Sugar Producer Magazine. Through a biological process called nitrification, soil microbes convert ammonium to nitrates that plants can absorb. Some may be involved in nitrification. A type of prokaryote (single-celled organism) called archaea has also been playing a role in nitrification. Black soil; Dibutyl phthalate; Sugar metabolic pathway; Sugar transporters.
