Groundwater is the main source of drinking water in Slovenia, but nitrate pollution originating from agriculture and urban areas is threatening its quality in several areas of the country. The aim of this study is to assess the vulnerability of three

Water pollution from agricultural activities has direct negative impacts on human health, as the well-known blue-baby syndrome —a potentially fatal illness —deriving from nitrate intake in infants. Inefficient farming practices, farming systems d

Nitrate leaching into groundwater is a serious issue in many parts of the world. Usually agricultural use of fertilizers is blamed to be the main source of pollution, but other human activities, like leaky or inexistent sewage systems can also be imp

Nitrogen-15 isotopic dilution method was used to estimate biological nitrogen fixation (BNF) and nitrogen (N) budget of fourteen (14) soybean varieties using maize as reference crop. The experiment was carried out at Sekou in Southern Benin. The amou

In soil redistribution studies employing 7Be, the radionuclide inventories and their spatial uniformity in soil can be influenced by the crop coverage conditions. A relatively high 7Be interception factor, normalized to the leaf area index (LAI), of

There is a deficit of mineral micronutrients in global food systems, known as ‘hidden hunger’, especially in the global south. This review focuses on zinc (Zn) and iron (Fe), whose entry into food systems depends primarily on soil and crop factor

The 7Be approach in estimating the erosion rates is based on the assumption that the deposition of 7Be fallout associated with the erosive event is spatially uniform. The objective of the present work was to verify this assumption by assessing the in

Phosphorous (P) fertilization is the major mineral nutrient yield determinant among legume crops. However, legume crops vary widely in the ability to take up and use P during deficiency. The aim here was to compare P uptake and translocation, biologi

Biological nitrogen fixation (BNF), nitrogen (N), and phosphorus (P) imports-exports budgets were estimated at four locations, each with 20 farmer-managed fields for two years in a semi-arid Tanzania and Malawi. The 15N isotope dilution method was us
