The concept of AS is based on the biological photosynthesis, by using sunlight, water, and carbon dioxide. While the utilisation rate of photosynthesis of most of crops is lower than 40%, AS can utilize it for over 80%. This photosynthesis is the biggest biological energy production on the earth. The nature of AS is very similar to that of algae.Benefits
Phosphate is often fixed in soils by the minerals such as iron and aluminum, which are present in the soil of many regions. Such phosphate fixation creates immobilization of phosphate in soils and becomes non available to the crop and consequently the growth and production of crop become undesirable.
To prevent such phosphate fixation in soils, there are several potential mechanisms for phosphate solublisation being used and among them, the fundamental technique is to apply as much organic compost as one can do. Applied organic compost then starts wrapping phosphate and protect from direct contact between phosphate and minerals.
Moreover, organic compost also develops large number of soil micro flora, which, to a great extent, also helps in solublising phosphate.
However, in the real situation of today's agriculture practice, obtaining enough organic compost is extremely difficult, due to the many factors such as climatic reason, increasing size of cultivable land, making compost with high laborer cost and high ingredients cost, scarcity of available animal fodder and high price of feed ingredients, etc.
Alternate to the organic compost, which is difficult to obtain in a large quantity, AS can be used in the place for the soil enrichment. Having high amount of organic carbon, nutrients, and ion exchangeable capability, in fact, AS could be a candidate for a future's biofertilize for sustaining the agriculture production.
By applying AS to the soil, exchangeable bases on the fixation of phosphate decrease.
1. Wrapping phosphate
When applied in the soil, AS develops large number of indigenous soil microbes. AS along with such increased soil microbes creates wrapping effect around phosphate and protect from fixation with iron and aluminum, Therefore, phosphate is freely available to the root of the plant.
2. Binding iron and aluminum
Inside the soil, due to the ion exchange effect, AS along with increased soil microbes also starts binding iron and aluminum in the soil. Such binding effect of AS reduces the chances of fixation of phosphate. Thus, phosphate can freely be available to the root of the plant.
As an Algae-Micro group, the source energy for production of AS is sunlight, CO2 and Hydrogen. All of which is abundantly available in the natural environment. Therefore, we can produce AS in unlimited volume. It could be a future´s biofertilizer and distributed to the farmers.
