A New Bifertiliser Using Microalgae Developed by a Technology Company

Bioalgal Marine, an Almeria University spin-off company specialised in cultivating and integral usage of microalgae has developed a new fertiliser manufactured from a microalga called Spirulina, called Algafert. This natural fertiliser visibly enhances plants' roots and resistance, without compromising its final quality, thanks to its innocuousness.
Bioalgal Marine, an Almeria University spin-off company specialised in cultivating and integral usage of microalgae has developed a new fertiliser manufactured from a microalga called Spirulina, called Algafert. This natural fertiliser visibly enhances plants' roots and resistance, without compromising its final quality, thanks to its innocuousness.

According to Marta Sánchez de Puerta, Bioalgal Marine's Manager, “this biofertiliser, which is particularly suitable for intensive agriculture crops, is simply a mixture of the microalga Spirulina, water and enzymes. This mixture is heated and, upon reaching a specific temperature, the microalgae break up and release the amino acids. By applying this fertiliser on the crops we save the plant the work of creating the amino acids, with which it grows faster.”

The main peculiarity of this microalga is its high concentration in amino acids, polysaccharides, phytohormones, oligoelements and antioxidants, which makes it the biological complement par excellence. All these substances, extracted using natural and environmental-friendly methods, act on secondary root growth, cell growth multiplication of the plant's mass, and multiplication of new shoots, as well as enhancing flowering, which in turn provides greater uniformity in the fruits, both in terms of size and their external appearance. Furthermore, it gives the fruits greater shine and consistency.

Benefits

The aforementioned benefits have already been demonstrated in typical Almeria crops that are being biologically treated, as well as on the strawberry crops in Huelva, olive plantations in Jaen, Cordoba and Granada, and in sub-tropical crops. The results obtained to date are responsible for the extension and commercialisation of this product throughout the whole of Andalusia.

For the strawberry crops, it is used with natural soil and with hydroponic cultivation, where the results, according to Bioalgal, exceed expectations, as apart from the expected enhancement of the fruit and the plant, “it is as if the soil had been regenerated”, explains Marta Sánchez. Used with the furrow cultivation method, the results are greater uniformity in the fruits and colour, longer petioles and disappearance of second category fruit, which does not generally have any commercial value.

As regards olive trees, following the use of this biofertiliser the olives' petioles grew longer, which facilitates harvesting, and the flowering was enhanced providing greater uniformity in the crop. Following treatment with Algafert, the hydroponic crops in Almeria showed greater resistance to hydric stress. Finally, all of this has the advantage that this biofertiliser can be used in ecological farming and with biologically treated crops.
