Abstract:
... Intercropping has been an important practice for improving field production and its various aspects have been thoroughly investigated. However, only few studies have explored it from the perspective of organic nitrogen (N) uptake, especially under the rapid development of organic and no-tillage farming worldwide. In this study, two cereals (Triticum aestivum and Zea mays) and two legumes (Glycine ...

Abstract:
... BACKGROUND: Stalk lodging (breaking of agricultural plant stalks prior to harvest) is a multi-billion dollar a year problem. Stalk lodging occurs when high winds induce bending moments in the stalk which exceed the bending strength of the plant. Previous biomechanical models of plant stalks have investigated the effect of cross-sectional morphology on stalk lodging resistance (e.g., diameter and r ...

The “one-wheeled tramline” for multiple machinery widths (OWTL) method, which implies confining compaction to only one common permanent traffic lane (PTL) without changing wheel tracks of the machinery, has been proposed as first step to adopt the Controlled Traffic Farming system. The objective of this study was to evaluate how far the stress distribution, caused by repeated wheeling, affects mai ...

They play an important role in plant modelling and are frequently used in fertilizer management tools. During the last 20 years, a number of studies have been conducted for comparing critical curves obtained in various conditions (e.g., different cultivars) and understanding the origin of their differenc ...
