Introduction. Promoting biological weed regulation by shifting resource availability and use from weed to crop may provide an option for a more sustainable weed management. Light is generally the main resource for which crops and weeds compete in conventional cropping systems. But, with the need to reduce mineral nitrogen fertilizer use, better management of crop-weed competition for...
Lack of control over fertilization is one of the major factors in the yield gap between smallholders and large oil palm plantations (Monzon et al., 2023). The diagnostic tool known as leaf analysis method is used by a large number of plantations to manage their fertilization and relies on annual leaf analysis and specific long-term experiments (Dubos et al., 2022). However, this method is not...
Introduction
While agricultural production is among the main drivers of anthropogenic climate change, projected effects of climate change and climate variability increase the pressure to provide food in sufficient quantity and quality at the same time. Inadequate nitrogen (N)-fertilisation practices, that fail to consider seasonally variable weather conditions and their impacts on crop...
1. Introduction
The synergy between different technologies such as field sensors and crop models is fundamental for crop monitoring growth and yield, while assessing climate change impacts at both field and broader scales. In the perspective of climate change mitigation, the implementation of biogeochemical cycles within crop models is essential to evaluate water and carbon (C) fluxes and...
- Introduction
Nitrogen (N) leaching losses to groundwater are an environmental risk in intensively managed agricultural systems. Among others, an adaptation strategy to mitigate such pollution risks is to reduce the fallow (bare soil) period duration by sowing cover crops after the winter grazing of forage crops (Carey et al., 2018). Cover crops can take up excess residual N after previous...

[Introduction]
Within field variations of plant available water capacity (PAWC) of soil is one of the major causes of spatial yield variability in dryland agriculture systems, as PAWC interacts with pre-season and in-season rainfall and other climatic variables to determine crop growth and final yield. Quantification of such variations helps to better understand the...
