Product Efficacy: The soil particle structure is optimized, becoming more loose and porous, and the air permeability and water permeability are greatly improved. At the same time, the root development of corn has changed significantly, with more secondary roots. The number of kernels per ear is increased by 50-80, and the 1000-kernel weight is increased by 5%-8%, finally achieving a yield increase of 7%-12% per mu.
