Hydrogen Production from Ammonia Electrochemical Cracking

Advanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Ex‐Ante Assessment of Farm Resilience to Institutional Shocks: A Modeling Approach

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Using the agent‐based model SWISSland, we simulate farm‐level responses and interactions under two institutional shocks: tariff reductions and direct payment reductions. Using a framework we developed, we assess resilience capacities, resilience attributes, and the provision of private and public goods, following the shock.

Changes of Tropane Alkaloids in Black Henbane (Hyoscyamus niger L.) in Response to Different Types of Nitrogenous Fertilizers

Journal of Medicinal Plants, 2017
Background: Since alkaloids are nitrogenous compounds, the availability of nitrogen (N) is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants.

Effect of nitrogen amount, time and 2,4-D+MCPA application on spatial distribution of lambsquarters seed bank in a corn field

پژوهشهای زراعی ایران, 2009
In order to evaluate the effect of nitrogen and herbicide management on distribution patterns of lambsquarters seed bank, an experiment was conducted in a grain corn field at the Agricultural Research Station, Ferdowsi University of Mashhad 2006 growing ...

Nitrogen in Feed and Fertilizer

Journal of AOAC INTERNATIONAL, 1973
Abstract Low values by Raney powder method 2.056 have been obtained on a few samples from one manufacturer. The values ranged from 0.2 to 5.0% nitrogen low. In relation to pollution, further work is reported in investigating digestion conditions and use of copper as a catalyst in Kjeldahl digestions.

Farmers' Preferences for Fossil‐Free Mineral Nitrogen Fertilizers: Role of Prices, Climate, Production Origin, and Identity

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Disruptions in global fertilizer markets and climate targets have increased interest in fossil‐free mineral nitrogen fertilizers. This study examines farmers' preferences for conventional (fossil‐based) and fossil‐free fertilizers using a labeled discrete choice experiment with 211 Swedish farmers.

Agronomic and Nutritional Perspectives on Vegetable Crops in Africa

AgriFood: Journal of Agricultural Products for Food, EarlyView.
Vegetable production plays a key role in food security, nutrition, and livelihoods across Africa. Moreover, African indigenous vegetables emerge as underutilized yet highly valuable crops, rich in macro‐ and micronutrients, as well as bioactive compounds with an array of health benefits.

CERTAINTY EQUIVALENCE FOR DETERMINATION OF OPTIMAL FERTILIZER APPLICATION RATES WITH CARRY-OVER [PDF]

This note demonstrates that a certain class of stochastic problems for determination of optimal fertilizer application rates in the presence of fertilizer carry-over can be simplified to static, certainly equivalent problems.
