Think of plain biochar as the ultimate blank canvas for your soil. It's pure carbon — a highly porous structure that acts like a sponge for nutrients, moisture and microbial life. Unlike chemical fertiliser that feeds your plants once and disappears, biochar sticks around for decades, quietly improving your soil every season.

This is the one for gardeners and farmers who want to charge it themselves — using compost, seaweed, leaf tea, or whatever inputs work best for your land. You're in control of what goes in. Or use it as a feed supplement for livestock and poultry; biochar is well regarded for gut health and reducing methane in animals.
