Effects of Different Organic Fertilizers on Sweet Potato Growth and Rhizosphere Soil Properties in Newly Reclaimed Land

It is well known that soil fertility poor in most newly reclaimed land, which has been developed as an effective way to compensate farmland occupation. In order ameliorate the quality of this study investigated effect commercial organic fertilizer (COF) (0.45, 0.90, 1.35 and 1.80 kg/m2), sheep manure (SM) 0.75, 1.05 mushroom residue (MR) (1.50, 2.25, 3.00 3.75 chemical compound (CCF) (0.075 kg/m2) on growth sweet potato, pH, matter content (OMC), available phosphate, total nitrogen, potassium, exchangeable Ca Mg, bacterial fungal microbial composition during 2019–2021. The results from indicated COF, SM, MR, CCF did not significantly change but increased OMC, regarded significant parameter. This suggests amendments used have great potential improve land. However, these exhibited a differential potato biomass, nutrient elements community soil, depend kind concentration organic/chemical fertilizer, application time, plant parameters. was also observed community, provides us with basis understand why improvement. Overall, our suggest amended fertilizers for production immature new reclamation
