چکیده
|
In agroforestry landscapes, land use, and the associated management practices exert strong impacts upon soil organic carbon stocks. data on the soil organic carbon were collected for different land-use types within a small watershed, el salado, located in lanjarón (se spain). eight land-use types namely: farmland planted in olive, almond, and cereals; forest with pinus halepensis mill. and pinus sylvestris l. stands; shrubland; grassland; as well as abandoned farmland were taken into consideration. of the land-use types investigated, forest, shrubland, as well as grassland exhibited the highest average soil organic c stocks (100-63 mg ha^-1) in contrast with the abandoned farmland (28 mg ha^-1), with farmland representing a go-between situation (51-49 mg ha^-1). the environmental factors precipitation, temperature, and elevation significantly influenced (p< 0.01) the soil organic c stock, with the contents tending to be higher in mountain soils with respective intermediate values of 600-800 mm, 10-15ºc, and 1,000-1,500 m asl. thus, the present approach offers a comparison of c-sequestration patterns as related to the land-use types in a mediterranean agroforestry landscape, where the main challenge is to integrate the forest trees and the crops within their harmonious interacting combinations.
