Investment in organic fertilizer production lines is becoming the focus of new start-ups, mainly because of the following:

1. Market demand growth: Organic agriculture and environmental awareness have promoted the increased demand for organic fertilizers, which provides a broad market prospect for investment in production lines.

2. Resource utilization: The use of agricultural waste (such as chicken manure, cow manure, etc.) to produce organic fertilizer is conducive to resource treatment and environmental protection, in line with the trend of sustainable development.

3. Government support: Many countries and regions provide policy support and financial subsidies for green agriculture and environmental protection projects, reducing investment risks and costs.

4. Technological progress: Advanced production technology and organic fertilizer equipment continue to emerge, making the return on investment of organic fertilizer production lines more attractive and more efficient.

5. Economic benefits: The production of organic fertilizer can create additional income, while reducing waste disposal costs, with good economic benefits.

Therefore, investment in organic fertilizer production lines is not only in line with the trend of environmental protection, but also has obvious market potential and economic benefits.
