Abstract Saline‐sodic paddy soils in the Songnen Plain suffer from nitrogen loss due to nitrification. The purpose of study is explore soil saline improvement and nitrification mitigation effects polyaspartic calcium (PASP‐Ca) by evaluating changes quality, nitrification, microbial communities. Four PASP‐Ca application treatments (additions 0, 500, 1000, 1500 kg hm −2 ) were studied an experiment saline‐sodic Plain, China. Results showed that significantly decreased pH, electrical conductivity (EC), water‐soluble salt ions, increased total carbon (TC), (TN), urease activity (UA), sucrase (SA). slowed down which was manifested a significant increase ammonium () decrease nitrate ammonia monooxygenase (AMO). composition distribution nitrifying communities affected salinity, nutrient, enzyme activities. Ammonia‐oxidizing bacteria (AOB) plays important role process soils, while inhibited suppressing AOB amoA gene abundance. This shows PASP‐Ca, as effective amendment, can improve salinization slow has significance improving utilization reducing soils.
