WHO CAN BE AFFECTED BY STRESSED AGRICULTURAL SOIL?

Farmers that are farming land with higher levels of heavy metals such as Cadmium, Cromain, Arsenic, Lead and Mercury.
Farmers in areas of high drought or water logging
Farmers with land subject to high salinity
Government agencies responsible for restoration of public land
Seed companies

WHAT ARE THE BENEFITS OF TREATMENT?

• Improved root systems in crops grown in heavy metal contaminated soils
• Protection of plants grown in heavy metal contaminated soils
• Improved tolerance to diseases under stress conditions
• Improved tolerance to drought conditions
• Improved tolerance to high salinity soils

RECOMMENDED MicroGen Biotech PRODUCTS

TPH-PAH-MBooster™: Helps plant to resist hydrocarbon stress conditions and enhance crop growth

Stressed soil can be a major inhibitor of agricultural production and globally represents a considerable loss in potential crop yield. Stresses can be biotic (like plant pathogens and insect pests) or abiotic (including drought, salinity, heavy metals). The latter type of stresses are of global significance with respect to agriculture in many parts of the world including China (1/5 of Chinese arable lands are contaminated with heavy metal). The general impacts of stresses on crops include nutritional and hormonal imbalances and increased sensitivity to disease. Some stress such as drought or salinity can have direct negative effects on plants by elevating levels of the plant hormone ethylene which leads to a reduction in root growth and other knock-on effects.

PGPB inoculation has been shown to lower ethylene levels in plants due to ACC deaminase activity in addition to providing other useful traits such as phytohormone synthesis and siderophore production. Heavy metal contamination of agricultural soils (due to legacy spreading of sewage sludge) is a major issue in many countries. Heavy metal tolerant PGPB have been shown to protect the plant against metal toxicity and increase root length, biomass and improve nutrient uptake under these conditions. An important consideration in developing PGPB products for combating stressors in agriculture is that the microbes are tolerant or resistant to the stresses involved. This is always the case in other commercially available products. In addition, PGPB that have an endophytic lifestyle have a more direct influence on their host plant.

Stressed_Agricultural_Soil3

MicroGen Biotech have developed specifically tailored PGPB that have the following properties; ACC deaminase (to lower ethylene levels), heavy metal tolerance and ability to withstand drought/high salinity conditions.
