One of the reasons for decline in agricultural land is soil degradation processes. The main negative processes occurring soils and leading to their are erosion (water wind) a decrease humus content soil.

in the present research land use changes modeling in the urmia city is considered in order to detect changes in agricultural lands. in this regard, landsat satellite images were used and then the object base processing satellite images was performed by applying the process segmentation and in the next stage, the optimization of scale segmentation and image analysis to its constituent elements, ...

This paper aims to examine the dynamics of land transactions, machine investments, and the demand for machine services using farm panel data from China. Recently, China's agriculture has experienced a large expansion of machine rentals and machine services provided by specialized agents, which has contributed to mechanization of agricultural production. On the other hand, the empirical results ...
