The rising price of fertilizers, environmental impact, and effective biological alternatives

The increase in fuel prices is causing shock waves in fertilizer prices due to the general shortage in the supply of raw materials, which can lead to disruption of the economic sustainability of farms due to high production costs.

Not only is the increasing prices of all factors of production a concern, but also the environmental problem associated with the excessive use of conventional fertilizers.

The excessive use of nutrients, especially Nitrogen and Phosphorus, has become a form of pollution, damaging ecosystems. Almost 80% of the Nitrogen used in fertilizers is lost to the environment through soil erosion, leaching, atmospheric conversion, and other forms of waste, causing a decline in the quality not only of the soil, but also of the water. Similar effects on soil and water quality occur with intensive application of Phosphorus, where 70 to 90% quickly becomes unavailable to plants. Thus, part of the Phosphorus accumulates in the soil, changing the pH, the ion exchange capacity, the diversity and functionality of the microbiome, and can also be lost to the environment.

The leached fertilizers will deposit in the groundwater and enter the waterways, causing the proliferation of toxic algae - cyanobacteria - which in turn trigger the darkening of deeper waters with the consequent death of the Posidonia sp. and Caulerpa sp. communities that provide oxygen to the water. The presence of toxins and the limitation of oxygen in the water negatively affects the entire trophic chain, including fish.

Examples of this climatic disaster are Lake Atitlán in Guatemala and the Mar Menor in Spain, where excess Nitrogen and Phosphorus are causing the proliferation of cyanobacteria and consequent deterioration of water quality.

One of the solutions to these problems is the use of new methods of nutrient supply, such as the use of microorganism-based biofertilizers that make nutrients bioavailable to the root system without the need to apply synthetic fertilizers.

In recent years, Asfertglobal together with the Faculty of Sciences of the University of Lisbon has developed solutions based on Nitrogen fixing and Phosphorus solubilizing bacteria that help plants obtain macronutrients essential to their nutrition, without any danger or pollution to the environment.

Kiplant All-Grip is composed of a microbial consortium — Bacillus megaterium, BS1 strain (CECT 30400) - 33.3%; Pseudomonas fluorescens, BS2 strain (CECT 30401) - 33.3%; Pseudomonas putida, BS3 strain (CECT 30402) - 33.3% — that contributes decisively to the solubilization of Phosphorus present in the soil and above all to the production of indole acetic acid, keeping the root system in constant growth. In addition, Kiplant All-Grip increases the presence of beneficial microorganisms in the rhizosphere (including mycorrhizae), resulting in better control of pathogenic microorganisms.

During the fermentation process of Kiplant All-Grip, secondary metabolites are produced that have a direct action on crop growth and productivity, with consistent results in a wide variety of soils, thus allowing an effective reduction in the use of chemical fertilizers.

The efficacy of this product has been highly tested, and we present here the results of two trials conducted by Anadiag and Solvitae (Certified Testing Companies).

Effectiveness of Kiplant All-Grip on cucumber production

The trial was conducted in the Montemor-o-Velho region, in a cucumber greenhouse of the Arianne var. Kiplant All-Grip was applied by fertigation at doses of 3 l/ha, 6 l/ha and 12 l/ha, divided into two applications made on 31/08 and 14/09/2017. As control were considered untreated plants inserted in the trial.

Graf. 1 — Total production

The production where Kiplant All-Grip was applied in doses of 3, 6 and 12 l/ha is statistically superior to the control plots. And the plots where Kiplant All-Grip was applied at a dose of 6 and 12 l/ha show a statistically higher yield than the plots where Kiplant All-Grip was applied at a dose of 3 l/ha.

Effectiveness of Kiplant All-Grip on yield and soil microbial community enhancement in greenhouse tomatoes

The trial was conducted in a greenhouse, in the Torres Vedras region, Portugal, var. Reconquista x Maxifort with tomato plants installed on the ground. Treatments were performed at 3 l/ha, 6l/ha and 12 l/ha of Allgrip, divided into two applications.

Graf. 2 – Total community of mycorrhizal fungi in the soil

Graf. 3 – Tomato yield (ton/ha)

The increase in mycorrhizal fungi was reflected in the yield of the crop, with a 22% increase in harvest.

Asfertglobal participates in the ABIM 2021 congress

Asfertglobal was present at the Annual Biocontrol Industry Meeting ABIM 2021. In recent years the development of Biocontrol solutions has been one of Asfertglobal’s priorities and for this reason we were present at ABIM 2021, the largest international meeting dedicated to agricultural Biocontrol.

Asfertglobal participates in the Fruit Attraction

Asfertglobal marks the 8th consecutive presence in Fruit Attraction. The Fruit Attraction 2021 edition exceeded all expectations due to the high number of visitors. It was three days of intense knowledge sharing and learning and a shared vision of the future of agriculture, based on innovation.


Asfertglobal was recognized with the COTEC 2021 INNOVATOR STATUS, by COTEC Portugal. A public recognition of Portuguese companies that, due to their high performance in innovation and notoriety, are an example of value creation at a national level.

customer experience
Fernando Fontes, a grower in the northern region of Portugal, after the Kiplant Allgrip application has increased production and reduced fertilizer units by 50%.

With the increase of soil and water contamination, it becomes important to respond to something that is becoming very demanding: less inputs in agriculture, i.e. less fertilizers, ensuring a good production.

Fernando Fontes is a tomatoes producer — Solanum Iycopersicum — in the region of Póvoa do Varzim. The farmer made two applications of Kiplant Allgrip at a dose of 1 lt/ha and got excellent results!

Better calibers, better setting and increased fruit weight. Besides the fruit, the plants were also stronger and healthier with the added value of being able to reduce by 50% the fertilizer units added to the crop, thus reducing production costs and promoting a sustainable and environmentally friendly agriculture.
