Abstract

Background and Objectives: Soil health is one of the factors contributing to food security and public health and hence achievement of sustainable agricultural goals. One of the factors affecting soil health is agronomic management. Different agronomic managements have different effects on soil health indicators, so that the positive effect of management of plant remains leads to the improvement of physical, chemical and biological properties of the soil. Considering that till now few studies have evaluated the effect of different types of agricultural management on chemical and biological properties in arid and semi-arid regions of Iran, Therefore this study was designed and conducted to evaluate the effects of different agronomic management on some soil chemical and biological indicators. Materials and Methods: The study was conducted in Research in Shahid Chamran University of Ahvaz. In this research, the effect of some different agronomic management (residual management, agronomic rotation and monoculture) on a number of soil health assessment indicators (pH, EC, microbial respiration, organic matter, active carbon, total nitrogen, available phosphorus, potassium, Iron, Zinc and Manganese was studied. The experiment was conducted in a randomized complete block design with four replications. Mean comparisons were done by Duncan's multiple range test method. Results: The results of analysis of variance showed that the crop management type had a significant effect (P<0. 01) on pH, EC, organic matter, microbial respiration and activate carbon. Monoculture cropping system caused a significant increase in pH (7. 29) and EC (3. 5 dSm-1) compared to the other agronomic management systems. The application of plant debris to Crop rotation and monoculture management increased the amount of soil organic matter, microbial respiration and soil activated carbon to 1. 7, 1. 4 and 1. 75 times. Also, the values of these traits in the Crop rotation system were more than monoculture management. Also, the management of plant remains with a ratio of 1. 8, 2. 3 and 1. 4 increased the iron, zinc and manganese levels. Conclusion: This study showed that soil EC, pH, organic matter, microbial respiration and activate carbon, total nitrogen, available phosphorus, potassium, iron, zinc and manganese in soil can be used as soil health indicators to evaluate the effects of different agronomic managements on soil health. Crop Residue management had more significantly effects on improving soil health indicators than Crop rotation and monoculture cropping systems. The soil health indicators were more in Crop rotation system compare with monoculture which shows the positive effect of rotation compare with monoculture. In general, the results showed that the crop Residue management can improve soil health indicators more than Crop rotation and monoculture.
