Precision planter monitoring system based on mobile communication network
IET Networks, EarlyView., 2022 Abstract Sowing is an important link in agricultural production and the basis for ensuring high yields and bumper harvests. Agriculture requires precision plows with good performance and stable work. However, the seeding process is in a completely closed state, and the operator relies mainly on experience to judge the operating state and performance of

Studies of Plough Design and Ploughing Relevant to Conditions in Northern Europe
Acta Agriculturae Scandinavica, Section B — Soil & Plant Science, 2002 Although the development of plough design has been on the agenda for hundreds of years, there is still room for improvements. The present study attempts to give an overview of previous work and to identify the areas having most potential for future improvement.

Journal of the Agricultural and Applied Economics Association, EarlyView.Abstract Greenhouse gas emissions from crop production contribute to anthropogenic climate change, while agricultural soils also sequester atmospheric carbon. Direct measurement of soil organic carbon (SOC) is limited by high sampling costs and the vast spatial extent of farmland.

Variation of tow force with velocity during offshore ploughing in granular materials [PDF]
, 2012 Pipeline plough behaviour has been investigated by means of reduced scale physical model testing. A testing programme was devised to investigate the influence of permeability, relative density, and plough depth on the associated tow force measured during

Long‐Term Analysis of Winter Wheat Yield and Climatic Influences in Ukraine
International Journal of Climatology, EarlyView.Long‐term field data (1968–2024) show that winter wheat yields in central Ukraine increased despite warming, but yield stability declined. Rising temperatures, more frequent soil moisture droughts and shortened winter calm increasingly limit productivity.
