What are biofertilizers?

Bio-fertilizer – microbial pollen – is a microbial vaccine from a variety of highly active microbial species. Bio-fertilizer works to encourage the biological role in the soil, as it represents the natural environment for the living of these organisms, as it plays a nutrient role for soil and plants:

Root ganglia bacteria of leguminous plants

It is a bacterium belonging to the genus Bradyrhizobium Rhizobium, where such bacteria fix nitrogen within the root nodes made by these bacteria as they penetrate the epidermal cells of the root hairs and live a symbiotic life. Atmospheric nitrogen inside their cells, then the plant benefits from it in the form of ammonia and amino acids, in addition to what these bacteria produce from natural plant hormones. It was found that for each plant species there is a specialized strain of rhizobia. Research results and applications have proven that rhizobia pollen stabilizes from 40-115 kg nitrogen / feddan annually, depending on the type of leguminous plant grown and the prevailing environmental conditions, which leads to increased productivity and rationalization of the use of added chemical fertilizers. These vaccines have been used successfully for decades, and the farmer has become aware of their value and benefit to the crop and the land.

Symbiotic nitrogen-fixing bacteria

It is a bacteria that fixes atmospheric nitrogen in the soil in a free way, where it obtains its needs of organic acids and energy from the products of the decomposition of organic matter by the action of soil microbes and produces ammonia and amino acids. Among the most important species used in the production of microbial vaccines:

The genus Azotobacter sp, where 30-35 kg of nitrogen / feddan annually, which is equivalent to 100 kg of nitrate fertilizer 33% nitrogen.

Azospirillum genus, where 25-30 kg nitrogen / feddan annually, equivalent to 91 kg nitrate fertilizer 33% nitrogen

Phosphorous and potassium facilitating bacteria

Converting phosphorous and potassium in the soil into a form suitable for use by the plant, as it secretes organic acids in a way that does not harm the soil or the developing plant, but rather benefits it, as in addition to the above, the secreted acids help to dissolve and facilitate some important elements such as iron, zinc and manganese. Examples of these phosphate-dissolving bacteria are Bacillus megaterium

And potassium-sparing, such as Bacillus circulans

Production of growth regulators and stimulants, plant hormones, organic and amino acids

It was proved by the analyzes that most of the biofertilization microbes have a tremendous ability to produce hormones similar to plant hormones such as gibberellin, indoles and cytokinin, in addition to what they secrete from organic and amino acids. – Increasing the branching – increasing the rate of flowering and the percentage of knots, reducing the percentage of flower drop, increasing the size of the fruits and improving their qualities and quality – increasing the rate of utilization of the plant from the nutrients in the soil.

Vitamin production

Where some microbial species, during their activity, produce a group of vitamins, especially the vitamin B group, and in balanced quantities, the plant absorbs them, which helps to increase the plant’s immunity to disease, in addition to raising the nutritional value of the crop.

production of antibiotics

Some microbes have the ability to secrete organic substances that stop, kill, inhibit or make the medium unsuitable for the growth of the pathogen. And researchers at the Desert Research Center were able to isolate some active bacteria used in biofertilizers and have the ability to prevent the spread of root rot fungi.

biological control

One of our products is the work of biological combinations of a group of fungi and some types of bacteria in biological control to reduce the incidence of fungal diseases, nematode diseases and insect infestations.

Sulfur-oxidizing bacteria (improved sulfur)

Addition of 50 to 100 kilograms of agricultural sulfur added to it bacteria oxidizing sulfur per acre, working to adjust the soil pH, where the soil pH is considered one of the most important factors affecting the availability of plants
