I'm looking for a reliable supplier of green fertilizer to support my agricultural operations. Specifically, I need a product that's sustainable, eco-friendly, and enhances soil health while promoting crop growth. Quality and efficacy are top priorities for me. If you have products that meet these criteria, I'd like to know more about your options, including the formulation details and any relevant certifications. Additionally, please provide information on your pricing, minimum order quantities, and lead times for delivery. It would be helpful to understand the packaging options available and whether you offer any bulk purchasing discounts. I'm keen on establishing a long-term partnership, so any additional insights into your company's eco-initiatives and production processes would be greatly appreciated. Looking forward to your response!
