Modeling of Soil Compaction Beneath the Tractor Tire using Multilayer Perceptron Neural Networks [PDF]
Journal of Agricultural Machinery, 2018 Introduction Soil compaction is one of the most destructive effects of machine traffic. Compaction increases soil mechanical strength and reduces its porosity, plant rooting and ultimately the yield. Nowadays, agricultural machinery has the maximum share

Parametric cubic equations for modelling mouldboard plough surfaces
Soil and Tillage Research, 1994 Abstract Mouldboard shape identification is needed to compare and analyse the performance of different plough bottoms. This paper presents a method for describing an existing mouldboard mathematically. The technique used is based on a Bezier form of three dimensional parametric cubics, and it focuses on an algorithm to improve the efficiency of ...

Mathematical model of a screw moldboard plough operation
Traktory i sel hozmashiny, 2014 Mathematical model, algorithm and computer model of undercutting and turning of soil layer by a screw moldboard of share plough body are presented. These models are based on predetermined soil layer motion law and dynamical interaction between layer and ploughshare, breast and wing of moldboard, surfaces of which are described by unstable functions.

Annals of Agrarian Science, 2018 Abstract The theory of the analysis of kinematic behaviour of the movement of furrow slice ripped by plough hulls on the example of ripping mouldboard has been developed. Working out the equation of surface of the mouldboard and using the analytical dependencies of the relative and absolute motion trajectories of the blade movement the mathematical ...

GCB Bioenergy, Volume 18, Issue 2, February 2026.This study assessed the industrial hemp value web resilience in the Swabian Alb, Southern Germany, where regional implementation remains limited despite hemp's bioeconomy potential. Using an indicator framework and stakeholder interviews, the research found the small, fluctuating cultivation area (e.g., 25 ha in 2024) focuses on hemp seed valorisation;

Partial budget analysis of reduced tillage and cover crops: 100 farmer interviews
Agronomy Journal, Volume 118, Issue 1, January/February 2026.Abstract Agricultural systems that enhance soil health are essential for conserving biodiversity and ensuring the sustainability of food, water, and energy resources. Practices such as reduced tillage and cover cropping are increasingly adopted by farmers seeking long‐term production efficiencies and conservation benefits.
