🌿 Blue-Green Algae Fertilizers: Sustainable Biofertilizers for Improved Soil Health
HOOK
As agriculture shifts toward more sustainable farming practices, blue-green algae (cyanobacteria) fertilizers are gaining attention as eco-friendly biofertilizers. By naturally contributing nutrients and improving soil fertility, they can help support crop productivity while reducing dependence on synthetic fertilizers.
HISTORY / OVERVIEW
Blue-green algae fertilizer utilizes selected species of cyanobacteria that can convert atmospheric nitrogen into forms available to plants. These microorganisms also contribute organic matter and may enhance soil biological activity, making them particularly valuable in integrated nutrient management systems.
Blue-green algae fertilizers have been widely studied and used in rice cultivation and are increasingly being explored for broader agricultural applications as part of sustainable farming practices.
