Biochar

Regenerate.
Retain.
Increase.

The organic soil improver that saves nutrients and boosts yields

Biochar provides a stable structure that works as a high porosity sponge. It helps regenerate degraded soils and increase yields by conserving nutrients, hosting beneficial microorganisms and retaining soil moisture. Triple benefits!

We produce BIOCHAR from rice husk (plants) that instead of being burnt, are transformed through a smokeless process into a carbon rich format. In doing so, we avoid greenhouse gas emissions and the resulting biochar brings life back to degraded soils.

We sell to input suppliers, wholesalers and agricultural cooperatives. Discover your nearest outlet to get HUSK products.

BIOCHAR Results and benefits

Format: 15 Kg bag (79 L).

*Scientific published literature suggests an increase of 50% water holding capacity over unamended soil.

** Our results in Cambodia show an average of 26% increase in crop yields which means higher revenues for farmers as well as a reduction in chemical fertilizers and pesticides and irrigation costs.

Soil types and applications

BIOCHAR helps water retention during the dry season and prevents waterlogging and compaction in the rainy season.

BIOCHAR is also very effective to speed up the composting process, so it can be mixed with organic matter at the beginning of the process to enhance the thermophilic phase. A different rate should be applied depending on the nutrient content of the initial materials*.

It has been proven to be effective in immobilizing heavy metals or toxic substances from the soil (i.e. Cacao plants absorbing Cadmium from soil) to prevent plant absorption.

*Please contact HUSK agronomists for specifics or see recommended dosage below.
