[Cost-Effectiveness] — Rice Fertilizer Efficiency Demonstration

The root system is well‑developed, with long roots and abundant white roots, and the stems appear robust. Nongda humic acid fertilizer promotes vigorous rice root growth, and when used in combination with Nongda Yibajia, it virtually eliminates the need for additional topdressing throughout the entire growing season.

[Cost-Effectiveness] — Over a hundred people gathered in Yutai, Jining, to witness the remarkable results of rice cultivation without the need for additional fertilizer.

At the Agricultural University, rice cultivation requires no topdressing—only a single application of base fertilizer at planting or transplanting, applied mechanically. Compared with conventional fertilization, this approach reduces nitrogen use by 20% while maintaining or even surpassing yields, thereby saving labor and easing the physical workload.
