Challenges
More inputs, more effort, fewer results.
The earth is tired
Cada cop costa més que respongui com abans. El sòl ha perdut vida. Décades de monocultiu, llaurat intensiu i ús constant de químics han anat esgotant la seva capacitat natural per sostenir els cultius.
Soils that no longer live
A large amount of soil today has become an inert substrate: it no longer retains water or preserves nutrients. It has become compacted, acidic, fragile… as if it were just a support, rather than the living organism it once was. This not only affects crop yields and quality, but also leaves the land more exposed to droughts, pests, and accelerated degradation.
Over 75% on the brink of collapse
If we do not act, it is estimated that by 2050 this figure will reach 90%. This silent degradation of soils not only threatens food security, but also impacts agricultural productivity and erodes the very foundation of our future.
What is Biochar?
A natural solution that transforms biomass into life for the soil
How is it obtained?
Biochar properties
The result is a stable, porous, and lightweight plant carbon, capable of retaining water and nutrients and hosting beneficial microorganisms within its structure. Unlike compost or manure, biochar does not decompose; instead, it remains active in the soil for centuries, helping to improve its structure and fertility over the long term.
Carbon sink
In addition to its agronomic benefits, biochar helps reduce the environmental footprint of agricultural activity. Biochar turns plant residues into a valuable resource that regenerates soils, improves crop efficiency, and contributes to climate sustainability.
Not all biochars are the same
Main factors that determine its quality, effectiveness, behavior, and benefits:
Raw material used
The type of source biomass (forest residues, agricultural residues, etc.) influences the composition of biochar. Each raw material provides different proportions of carbon, ash, minerals, and porosity.
Pyrolysis process conditions
The temperature, time, and absence of oxygen during production determine the internal structure and stability of biochar. Poorly processed biochar may contain volatile compounds or have an unsuitable pH, reducing its agronomic effectiveness.
Degree of activation
Raw biochar is biologically inactive. That’s why at ALERE Circular we apply an activation process through composting and controlled microbiology, which stabilizes the material and enhances its ability to retain water, nutrients, and host beneficial microorganisms.
Suitability for soil type and crop
here is no universal biochar. Its particle size, pH, and surface charge must be adapted to the characteristics of the soil (sandy, clayey, etc.) and the goals of the crop (fruit trees, vegetables, nurseries, etc.).
Products
ALERE Regenera ®
Organic Fertilizers with Activated Biochar
Vitality for your soil. Yield for your crop.
At ALERE, we develop solutions that work in harmony with the earth. ALERE Regenera ® is our line of high-quality organic fertilizers with activated biochar, designed to restore the soil’s structure, fertility, and natural balance. More than a fertilizer, it is a complete regenerator of the soil ecosystem.
What does Activated Biochar mean?
The activation of biochar is a process carried out to enhance its physicochemical and biological properties before applying it to the soil, thereby increasing its agronomic benefits.
Technology that regenerates
Activated biochar acts like an intelligent sponge within the soil: it retains water and nutrients, improves the microbial habitat, and reduces greenhouse gas emissions. A regenerative tool with immediate and lasting impact. ALERE Regenera ® contains high-quality biochar activated with locally sourced organic compost, creating a highly effective and durable product for agricultural soils.
¿Qué hace ALERE Regenera ® por tu campo?
Regenerates soil life
Improves soil structure and balance. Provides stable organic matter that enhances biological activity. Corrects acidic soils by regulating pH and promoting optimal conditions for crops.
Water and nutrient efficiency
Retains more moisture and reduces the need for irrigation. Reduces leaching and nutrient losses. Releases immobilized nutrients and improves their absorption by the roots.
Crop growth and vigor
Stimulates deep and healthy rooting. Increases plant vigor and leaf nitrogen content. Improves crop quality and yield.
More resilient crops
Strengthens the plant against pests, diseases, and water stress, helping maintain its performance even under adverse conditions.
Main crops:
Fruit trees and nuts
Vineyards and olive trees
Lawns and green areas
Nurseries
ALERE Regenera ® Benefits
A natural solution that regenerates the earth, captures carbon, and builds the future
Fertility and resilience
Biochar acts as a booster of soil fertility and resilience: thanks to its porous structure and high cation exchange capacity, it retains essential nutrients and reduces their leaching, ensuring they remain available to plants for longer.
Soil structuring
Biochar acts like a sponge, improves soil aeration, and provides a stable physical and chemical support that protects and prolongs the life of beneficial microorganisms in the rhizosphere, directly impacting crop health and productivity.
Very long-lasting lifespan
Its true power lies in its extraordinary stability: it remains active for centuries, creating a permanent reserve of carbon and nutrients that supports low-emission, more profitable agriculture in the long term.
Biochar + Compost
Combined with compost, it becomes a unique regenerative alliance: it extends the action of humus, acts as an enhancer of the humic fraction, and multiplies the efficiency of each application.
The result is more vibrant, fertile, and stable soils, capable of producing healthy crops even under adverse conditions.
About us
Regenerate the earth, nourish tomorrow
ALERE. Good for Earth
We were born with a deep conviction: soil health is the foundation of a sustainable future. We are a company specialized in soil regeneration and sustainable agriculture, committed to restoring the vitality of the earth while caring for the planet. That’s why we work hand in hand with farmers who believe in a way of cultivating that respects soil life and protects the future.
Vision and Mission
At ALERE, we produce organic products based on biochar, a regenerative technology that improves soil structure, increases water and nutrient retention, enhances the presence of beneficial microorganisms, and boosts organic matter. All of this results in healthier, more resilient, and productive crops, even under adverse climatic conditions.
Our approach combines soil science with ecological innovation to provide solutions that reduce the environmental impact of agriculture, capture carbon, and regenerate the soil’s natural fertility.
