Materials and MethodsTemperature monitoring
Automatic temperature detector Monitored and recordedTemperature error ±0.1˚C
Take soil sample to measure soil catalase, urease,
phosphatasesoil organic matter(N,P,K), pH,
salt
the soil organic matter was 7.15g/kg total N was 0.15 g/kgtotal P was 0.15 g/kgavailable N was 5.6 g/kg available P was 6.6 g/kg available K was 365.1 g/kgsoil pH was 9.2 total salt was 2.8 g/kg
