Using machine learning to generate an open-access cropland map from satellite images time series in the Indian Himalayan region

Crop maps are crucial for agricultural monitoring and food management and can additionally support domain-specific applications, such as setting cold supply chain infrastructure in developing countries. Machine learning (ML) models, combined with freely-av ...

Automation in steep terrain agriculture: an optimal controller to prevent tipping and slipping of tethered robots on slopes

Josephine Anna Eleanor Hughes, Max Mirko Polzin

Autonomous robots have the potential to fundamentally transform conventional farming methods, e.g. by enabling economically viable farming of sloped arable land. However, navigation on slopes in harsh conditions is challenging for robots as they must be pr ...

Using PhenoCams to track crop phenology and explain the effects of different cropping systems on yield

Christoph Bachofen, Yujie Liu

CONTEXT: Crop phenology integrates information of how environmental drivers and management practices affect plant performance and crop yield. However, little is known about the impact of cropping systems (CS) on crop phenology and how this relates to diffe ...

Legacy effect of green manure crops fertilized with calcium phosphite on maize production and soil properties

Alexandre Buttler, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja, Mario Fontana

Recycling phosphorus (P) is crucial to meet future P demand for crop production. We investigated the possibility to use calcium phosphite (Ca-Phi) waste, an industrial by-product, as P fertilizer following the oxidation of phosphite (Phi) to phosphate (Pi) ...

Community seed network in an era of climate change: dynamics of maize diversity in Yucatán, Mexico

Marianna Fenzi

Local seed systems remain the fundamental source of seeds for many crops in developing countries. Climate resilience for small holder farmers continues to depend largely on locally available seeds of traditional crop varieties. High rainfall events can hav ...

Valorization of calcium phosphite waste as phosphorus fertilizer: Effects on green manure productivity and soil properties

Alexandre Buttler, Luca Bragazza, Thomas Guillaume, Mathieu Raymond Santonja, Mario Fontana

The potential to use calcium phosphite (Ca-Phi) as phosphorus (P) fertilizer may represent an effective recycling of P-containing by-products. A greenhouse experiment was conducted to investigate the effect of Ca-Phi (38 kg P ha(-1)) on soil properties and ...

Species identity, rather than species mixtures, drives cover crop effects on nutrient partitioning in unfertilized agricultural soil

Alexandre Buttler, Pierre Rémi Mariotte, Mathieu Raymond Santonja, Lucas Georges Jean-Paul Freund

Aims Previous cover crop studies mainly focused on the links between plant uptake and soil fertility, and there is a clear knowledge gap regarding the role of microbes in these processes. Our aim was then to better understand the effects of plant mixtures ...

Comparison of high density and nitrogen seeded detachment using SOLPS-ITER simulations of the tokamak a configuration variable

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Kevin Henricus Annemarie Verhaegh, Mirko Wensing, Hugo De Oliveira, Lorenzo Martinelli

First of a kind SOLPS-ITER simulations on tokamak a configuration variable (TCV) that include nitrogen have been performed to model recent nitrogen seeded detachment experiments. Based on spectroscopic measurements, a nitrogen recycling coefficient R-p(N) ...

Long-term effects of crop succession, soil tillage and climate on wheat yield and soil properties

Mathieu Raymond Santonja, María Paula Sanginés De Cárcer

Climate change is increasing crop losses and yield variability with impacts for global food security. In this context, conservation agriculture appears as a potential solution to maintain crop productivity, soil fertility and environmental sustainability. ...

Model of crop growth, water flow, and solute transport in layered soil

David Andrew Barry, Jiancheng Yang

Agro-ecohydrological models are essential for managing scarce water resources and ensuring crop productivity. Here, a one-dimensional agro-ecohydrological model, LAWSTAC, capable of simulating water and solute transport in layered soil coupled with crop gr ...
