Patanita |The evaluation of the role of different agronomic strategies in achieving sustainable wheat yields under variable Mediterranean climate conditions may involve the use of resource-use indicators that combine productivity and environmental impact.[...]
Article
A l'exception des légumineuses qui peuvent fixer l'azote atmosphérique, la quasi-totalité des espèces cultivées ont besoin d'un apport externe d'azote sous forme d'engrais chimiques ou organiques ou encore d'engrais vert. En effet, l'azote est l[...]
Article
Improvements in the sustainability of agricultural production depend essentially on advances in the efficient use of nitrogen. Precision farming promises solutions in this respect. Variable rate technologies allow the right quantities of fertili[...]

Cheng |Although nitrogen (N) is a limiting factor for food production (FP) in Africa, and African food security is seriously threatened by the phenomenon of soil N depletion, there is a dearth of information that shows the points to focus on throughout[...]
Article
The most spread groundwater-dependent ecosystems in the River Po valley are semi-natural lowland springs called “fontanili”. They provide specific habitats and support high biodiversity, but are often strongly impaired by agricultural pollution.[...]

Decision support systems and models for aiding irrigation and nutrient management of vegetable crops
Vegetable growers in Europe are continually under increasing pressure to optimize irrigation and nutrient management. This results from the widespread effects of climate change and of competition from other sectors for water, and increasing soci[...]
Article
Land Cover (LC) and Land Use (LU) changes are usually considered as one change, limiting the understanding of their individual effects on Ecosystem Services (ESs). The aim of this study is to investigate the different effects of LC change and LU[...]
Article
Agricultural specialization has disconnected crop and livestock production in many farms and regions. As a result, crop farms are deficient in nitrogen to fertilize their crops, while livestock farms are deficient in proteins to feed their anima[...]
Article
In intensive agricultural systems, irrigation and nitrogen (N) fertilizer are the most important factors that influence crop production and N losses. This work aimed to evaluate the N best management practices using the calibrated and validated [...]
