Impact of fine fragmentation of arable land on carbon emissions from crop cultivation

The following are the impacts of arable land fine fragmentation on carbon emissions from crop cultivation:

1. Mechanization: fine fragmentation of arable land leads to a decrease in the degree of agricultural mechanization. Farmers using traditional non-mechanized cropping methods on small fragments of arable land will increase manual tillage and harvesting, thus increasing fossil fuel consumption and carbon emissions.

2. Transportation costs: The cost of transporting crops and agricultural products will increase as the distance between cropland and crops becomes larger due to the fine fragmentation of cropland. The need to use large amounts of transportation and fuel will also increase carbon emissions.

3. Land use efficiency: Cropland fragmentation leads to a decrease in land use efficiency, as smaller fragments of cropland are not as efficiently utilized as larger pieces of cropland. This leads to wastage of arable land, which affects carbon fixation and carbon emission.

4. Soil carbon stock: Cropland fragmentation affects soil carbon stock. The soil of small fragmented cropland is subject to different degrees of disturbance and management, and the storage and protection of soil organic carbon is not as good as that of large cropland.
