Integrated Crop-Livestock Systems
Integrate livestock into crop-rotation cycles to rebuild soil fertility and cut synthetic fertiliser inputs.

The ask
Build an agri-services company that helps Bangladeshi smallholders integrate livestock — cattle, ducks, or goats — into their crop rotation sequence, reducing synthetic fertiliser dependency, improving soil organic matter, and diversifying farm income through advisory services, input supply, and output aggregation.
Why now
Bangladesh's fertiliser import bill is a chronic foreign-exchange drain and a food-security vulnerability: the country spent over $1.5 billion on urea imports in 2022. Integrated crop-livestock systems can cut synthetic nitrogen requirements by 40–60% on well-managed plots — a well-documented result from South and Southeast Asian trials. The government's recent fertiliser subsidy rationalisation is making the cost of conventional farming increasingly visible to farmers, creating an opening for advisory models that offer a clear cost-reduction story.
Why Bangladesh
Most Bangladeshi farms already keep some livestock — the opportunity is formalising the rotation and building the infrastructure (compost units, fodder crop strips) to capture the fertility benefit systematically. Duck-rice integration is traditional in the haor wetlands and has been proven at scale in Vietnam; cattle-rice integration is well understood in the southwest. A service that maps the rotation calendar, supplies the compost structures, and aggregates the organic produce for premium urban markets turns a subsistence habit into a margin-positive system.
As a business
Revenue comes from three stacked sources: advisory subscriptions (৳500–1,000 per farmer per season, sold in blocks to NGO and cooperative networks); input supply margin on compost equipment and biofertilisers; and a produce aggregation premium — organic or reduced-chemical rice and vegetables fetch 20–40% more at Dhaka's growing premium grocery chains. The aggregation layer is where the real scaling leverage lies.
Economics
Move the sliders to model your own integrated crop-livestock advisory. Defaults are order-of-magnitude estimates — pressure-testing them is part of what a founder pitches us.

What ZEPH would back
A founder with extension-work experience who has already piloted the integrated system with 20 or more families and can show soil-test data and farmer income improvements. We want the agronomist-entrepreneur who understands both the ecology and the supply-chain logistics of getting clean produce to premium buyers.
Impact
Cutting synthetic nitrogen requirements by 40–60% across enrolled farms reduces Bangladesh's fertiliser import bill — the country spent over $1.5 billion on urea imports in 2022, with embedded production emissions of approximately 2.7 kg CO₂e per kg of urea avoided. At 500 enrolled farmers reducing urea use by an average 40 kg/farmer/season, the business prevents roughly 108 tonnes of CO₂e per year from avoided urea production and N₂O field emissions, compounding as the farmer base scales. Organic and reduced-chemical produce commands 20–40% premiums at urban premium grocers, creating a traceable value chain that can support certification revenue. Improved soil organic matter from compost integration sequesters additional carbon measurable under Verra VM0042 improved agricultural land management protocols.
