Abstract

This study was conducted to evaluate the impact of municipal waste compost and manure on soil chemical and physical properties quality and crop production in Sari city (north of Iran). In this study, the effect of compost and manure (cow and sheep) on the quality of soil organic material with experimental measurements was investigated. An experiment was conducted in a completely randomized design with 15 treatments and measurements with3 replicated. They have applied annually for 3 years to fifteen different plots. The soil of the study area was predominantly silty clay with temperate and humid climates. The following parameters were determined:1) Soil chemical properties comprising pH, 2) electrical conductivity and soil organic matter, 3) physical properties including 4) bulk density,5) void ratio, and6) plant yield were investigated. The electrical conductivity and pH. Also, showed considerable changes. As well as, results showed that utilization of municipal waste compost and manure caused significant differences in organic matter, bulk density, void ratio, and yield at 1% significance level compared with the control treatment. Finally, it can be concluded that organic matter has pronounced effects on the physical, chemical and biological properties of soil and the use of organic fertilizers will definitely improve soil quality and productivity.
