CASI is opting for natural fertilisers


It is researching how to minimise the impact of chemical fertilizers in the productivity of the soil, alongside Nostoc Biotech, Mabe and the UAL.

Using the research project ‘Biofertilisers’ as an important tool to reduce consumption and contamination due to the loss of traditional fertilisers in intensive farming, CASI, MABE, Nostoc Biotech and the University of Almeria (UAL) are attempting to show that it is possible to reduce chemical fertilisers by up to 20% on pepper and tomato crops, with the application of natural alternatives, such as worm humus. The result of these studies could be available in March.

CASI has indicated that “the incorporation of these new technologies to the soil will make our farming more sustainable, obtaining healthier produce and with less residue, increasing produce shelf life. The abusive use of some fertilisers and pesticides, and the lack of new organic matter added to the soil have all caused low yields, which opens up a gap for the use of more technical products that encourage the soil’s microbiology.”

Francisco Martín, technical manager at Nostoc Biotech, explains that “we want to use these studies to prove how the application of specific microbiological communities, present in worm humus, can help to reduce the use of chemical fertilisers in farming by up to 20% and, at the same time, increase the production and quality of the crops treated.”

The Government of Andalusia has up-dated the recommendations and requirements to fight against contamination by nitrates from farming in the Region’s water supply. This readjustment intends to meet the targets set by the European directive on protection against nitrates in water in farming.

And the fact is that ecological farming is still a pending task in many regions of Spain, they comment. On the other hand, in other areas, such as Almeria, they are leading the changeover to more environmentally-friendly farming, free from residues and chemicals.
