The problem

A rice grower in Jilin Province, northeastern China was producing rice under severe saline-alkali soil conditions, with soil pH of 9–10 and salinity of 0.5–0.6%. In this region, seedling emergence commonly falls below 50% and long-term reliance on NPK fertilizers has contributed to degraded soil biology and chronically low yields. The trial evaluated whether Sunrise Soil Probiotic, an OMRI Listed and CDFA registered multi-strain microbial inoculant combining beneficial bacteria and fungi, could improve rice performance under these conditions. Trial fields covered 3,500 m² and were transplanted in June 2015 with harvest in October 2015. Both the control and Sunrise-treated fields were pretreated with EM bacteria to neutralize pH and salinity, isolating Sunrise as the differentiating input between the two plots. Sunrise was applied at a rate equivalent to 14.4 g/1,000 m² of the standard 50 billion CFU/g formulation, mixed into the soil at transplanting. A single NPK application was made mid-cycle, with no base fertilizer or pesticides used.
