Biochar acts as an underground reservoir that protects your harvest against water stress, reduces fertilizer bills, and stimulates root development from day one.
Biochar is chemically stable for more than 1,000 years (certified MRT). A single, correctly activated application permanently modifies the soil architecture.
Its microporous structure fixes nutrients at the root and prevents nitrogen and phosphorus leaching, reducing dependence on synthetic fertilizers.
It acts as a natural sponge that retains available moisture, increasing drought tolerance in critical months by up to 25%.
It optimizes irrigation efficiency and allows for a 20% to 40% reduction in the use of phosphate fertilizers in each campaign.
Its 380 m²/g surface area decompresses the soil, improves root oxygenation, and prevents waterlogging during heavy rains.
It serves as a refuge for mycorrhizal fungi and beneficial bacteria, protecting them from extreme heat and strengthening the plant against pathogens.
Unlike conventional organic amendments, it does not degrade. A single activated application transforms the soil structure forever.

Technical note
Guideline dosages based on Schmidt et al. (2021) EBC Guidelines; Lehmann & Joseph (2015) Biochar for Environmental Management; Carboliva’s own SIR trials in Alentejo and Extremadura (2022-2024). Consult the product technical data sheet for specific conditions.
SOLUTIONS
Pure Carboliva Biochar must be activated before applying it to the ground (or used as livestock bedding to be charged with nutrients); otherwise, it will absorb water and fertiliser from the soil.
Farms with their own compost, slurry, or microbiology, and livestock or poultry farms looking for a dual use.
Requires mandatory prior activation (1:3 mixture by volume for 7-14 days in wet conditions) or direct use as livestock bedding before going to the field.
With Activated Carboliva Biochar you get speed: it comes ready with compost and microorganisms to act from the first irrigation without prior preparation.
Farms looking for immediate nutrition and direct application without spending labour on activation.
Listo para usar. It is incorporated into the ground using a traditional fertiliser spreader, at the bottom of the furrow, or localised in the planting line without any risk of immobilising nutrients.
Biochar in numbers
Reduces irrigation frequency in critical summer months and retains moisture in the root zone.
Unlocks nutrients fixed in the soil and prevents fertilisers from being washed away by leaching.
Direct increase in organic carbon in soil analyses from 24 months onwards.
Absorbs moisture in livestock and poultry bedding, improving animal welfare and loading the bedding with nutrients.
