南非采购需求：有机肥、高氮肥、缓释肥、液体肥、蔬菜肥、花卉肥

I'm interested in your range of fertilizers and would like to get a deeper understanding of what you offer. It would be great if you could provide details on the types of fertilizers available, their specific formulations, and any unique features that set them apart from others in the market. I'm particularly curious about the application methods and the recommended usage rates for different crops. Additionally, could you share information on your production capabilities, including packaging options and lead times for delivery? If you have any data or case studies that demonstrate the effectiveness of your products, that would be really helpful too. Looking forward to your response!
