N-(N-butyl)thiophosphoric triamide/NBPT
Urease inhibitor is a kind of substance that can inhibit the activity of soil urease, and it is a new technology which has been studied in urea or nitrogen compound fertilizer. Using soil urease inhibitor can effectively slow decomposition of urea into ammonia process, reduce soil NH4 + and NH3 concentration, soil fertility and crop fertilizer synchronization. NBPT is the most effective inhibitor ...

N-(N-butyl) Thiophosphoric Triamide Solution
N-Butylthiophosphoric triamide (NBPT, hereinafter referred to as "NBPT") is currently one of the most effective soil urease inhibitors. Agricultural fertilizers, mainly nitrogen fertilizers, are quickly decomposed by urease in the soil under normal use. This not only wastes a lot of nitrogen fertilizer resources, but also increases the cost of crop production, and brings a series of problems such ...

Modeling the impact of nitrate fertilizers on groundwater quality in the southern part of the Nile Delta, Egypt
The use of fertilizers in agriculture in Egypt, especially nitrogen, has increased significantly in the last decade, resulting in nonpoint contamination of the groundwater resources. This study investigated the effect of using nitrogen fertilizer on groundwater contamination with nitrate in the central southern part of the Nile Delta. NO3− concentrations in shallow groundwater were assessed ...

Are agricultural chemicals affecting our water?
With the rate at which modern towns and cities expand it’s inevitable that the volume of separation between agricultural facilities and highly populated areas is shrinking. The loss of these areas can have a lasting impact, particularly when it comes to our water supplies. From an increase in water treatment prices to potentially dangerous levels of nitrogen, agricultural facilities ...

Reducing agricultural nitrogen inputs in the German Baltic Sea catchment – trends and policy options
We depict recent agricultural nitrogen input and future loads to be expected in 2021 in the German Baltic Sea catchment to assess the feasibility of reaching water quality targets defined by the Marine Strategy Framework Directive (MSFD). We calculate recent and future nitrogen balances from agriculture by applying an interdisciplinary modelling system, also considering the effects of the ...

Evaluating cumulative effects of anthropogenic inputs in Prince Edward Island estuaries using the mummichog (Fundulus heteroclitus)
Estuarine eutrophication as a result of agricultural land use including the use of chemical fertilizers is increasing worldwide. Prince Edward Island, Canada has very high agricultural intensity by international standards with approximately 44% of the land area under production, and some watersheds in excess of 75% agricultural land‐use. The type of agriculture is also intensive with primarily ...

A dynamic analysis of nonpoint pollution control instruments in agriculture
Nonpoint pollution from agriculture is an emerging issue in the environmental policy of the European Union. Dynamic optimisation techniques are important in nonpoint pollution, and neglect of dynamic aspects may seriously mislead the proper design of policy measures. This paper presents an empirical assessment of nitrogen pollution abatement in the Ebro basin of northeastern Spain. The aim is to ...
