Current fertiliser recommendations for nitrogen are limited in their accuracy and may be improved by the use of simple on-farm soil rapid tests. This paper investigates the potential for using nitrate (NO₃⁻) ion selective electrodes (ISEs) and dual wavelength UV spectroscopy as part of a rapid...

Given that we must farm land in order to eat, the total environmental burden imposed by farming a crop, such as winter wheat in the UK, appears to be close to the minimum given current production techniques. The value of the services other than food production, such as flood water buffering,...

Past research about the efficiency of nitrogen application in winter wheat (Triticum aestivum L.) based on source and timing has produced inconsistent results. The majority of the literature used data from few locations over short time periods. This study used a unique data set of yields and...

Traditionally, cereal crop harvest residues are communally grazed by the ruminant herds of villagers and transhumant pastoralists in the agro-pastoral systems which predominate in the savannah zone of West Africa. We analysed the impact of the private use of crop residues by individual farmers...

A 2-year field experiment was carried out in Central Italy on processing tomato (Lycopersicon esculentum Mill., cv. PS1296) to assess the effect of fertigation–irrigation frequency on crop N uptake and yield. The crop was grown with three N-fertiliser rates (0, 100 and 300kgNha−1: N0, N100...
