Mechanized excavation of fruit and forest seedlings [PDF]

Savremena poljoprivredna tehnika, 2019
The paper presents the possibilities of mechanized harvesting of fruit and forest seedlings. For this purpose, special purpose plows with a special working body are most used for undercutting the soil layer and the root system of seedlings with the lifting and shaking of a part of the soil. Older plow solutions for fruit and forest seedlings still used

Does agricultural mechanization promote green development? evidence from an entropy-weighted provincial panel in China (2011–2023)

International Journal of Agricultural Sustainability
While agricultural mechanization is central to rural transformation in China, its ecological implications remain unclear. This study examines whether mechanization promotes agricultural green development or induces input-intensive ecological trade-offs ...
