印度采购需求：无机肥、有机肥、农药、植物生长调节剂

I'm interested in exploring options for NPK water-soluble fertilizers. Could you provide detailed information on your product range, including formulations, packaging sizes, and pricing? Additionally, I'm looking for any available samples and technical data sheets that outline the nutritional content and application guidelines. It would be great if you could also share any certifications or quality standards that your products meet. Thanks!
