Cover crops, conservation tillage systems and organic fertilizers have played an important role in maintaining or enhancing soil quality. In order to assess the combined effects of these techniques on soil quality an experiment was conducted as split Plot experiment based on randomized complete block design with three replications at Shahid Bahonar University of Kerman in 2011-2012.  &nbs...

Soil quality is the permanent soil ability to function as a live system within ecosystem under different land uses. Investigating the impact of land use type on soil quality indicators could help to distinguish sustainable managements and therefore, to inhibit soil degradation. In order to evaluate the effect of different land uses on soil quality indicators, a research based on a randomized co...

  Adopting proper agricultural management and conserving soil organic matter are important components of sustainable agriculture. Soil organic matter content is a key attribute in soil quality. Labile organic matter pools can be considered as suitable indicators of soil quality that are very sensitive to changes in soil management practices. This research was carried out to investigate some org...

Most part of the applied phosphorus is fixed in the calcareous soil. Some part of residual phosphorus can be recovered by the plants of the following years. It is reported that organic matter is one of most important factors in phsphorus recovering. This expriment was designed in permanent plot to evaluate the effect of organic matter on residual phosphorus recovering in a calcareous soil. The ...

Abstract Background and objectives: Access to real information and data on the impact of watershed management projects and their technical and economic evaluation is possible through representative and paired catchments. Since management operations and topographic characteristics have a great impact on carbon retention in ecosystems, this study aimed to determine the amount of soil organic ca...

The management and application of organic wastes in agricultural lands decreases environmental risks and increases utilization of these matters. The objective of this research was to investigate and compare the effect of polyacryl factory sewage sludge (PSS), municipal compost (MC) and cow manure (CM) on soil properties and on yield and growth of maize (single cross 704, Zea mays L.). The treat...

Application of compost and compost leachate as organic fertilizers can improve plant growth, nutrients uptake and increase phytoavailability of nutrients in soil. A factorial experiment (4×4×2) was conducted in a completely randomized design to evaluate the effect of compost and compost leachate on growth and chemical composition of barley and bioavailability of some nutrients in calcareous cla...
