Different Contribution of Olive Groves and Citrus Orchards to Soil Organic Carbon Sequestration: A Field Study in Four Sites in Crete, Greece

چکیده
In this work, we evaluated the effects of cultivation practices and sites (representing four locations in Crete, Greece) on soil organic carbon sequestration established citrus orchards, olive groves, uncultivated fields (used as a control). Soil pH, texture, matter (SOM), Permanganate Oxidizable Carbon (POXC), Total Kjeldahl Nitrogen (TKN), ratio (C:N), well CO2 respiration rates, specific enzymes’ activity (i.e., N-Acetyl Glutamate (NAG), Beta Glucosidase (BG), Dehydrogenase) were determined upper layer (0–20 cm). It was shown that orchards under South Mediterranean conditions could substantially increase C storage soil. However, soils planted with orange trees showed lower capacity than trees, which related to litter chemistry leaf C:N ratio). Sites had no significant impact SOM. our study, SOM positive relationship TKN (and less POXC) tree crop species litter. Our findings have implications for designing conservation developing initiatives describing achievable targets restoration depending properties cropping systems.

متن کاملDynamic Changes of Soil Surface Organic Carbon under Different Mulching Practices in Citrus Orchards on Sloping Land
Mulching management has been used in many places all over the world to improve agricultural sustainability. However, the cycling of carbon in the soil under applications of mulch on sloping arable land is not yet fully understood. A four-year field experiment was carried out in Xiaofuling watershed of Danjiangkou reservoir in China. The object was to evaluate the effects of the application of s...
