The effects of fertilizer N on yield and on clover/grass ratio over a 2-year period (seventh and eighth harvest years) subsequent to 6 harvest years during which no N fertilizer was applied were investigated. The data for productivity and persistence have already been published (McBratney, ...
Forage quality of species-rich mountain grasslands subjected to zero, PK and NPK mineral fertilization for decades To maintain species-rich swards from which forage of a high nutritional quality can be produced, it is essential to adapt grassland fertilization strategie...

although recent work highlights their importance for maintaining plant diversity16. One emerging pattern from work in natural systems is that pathogens often thrive in resource-rich environments9,17, and fertilizer addition has been linked to increased disease incidence in plants18,19. This effect is...
Sectorial analyses can mislead conclusions, prompting the need for integrated approaches. We present a multiscale analysis of N flows for the 1990–2015 period to identify both the strengths and weaknesses of the Spanish agro-food system. We constructed N budgets at three system scales, namely ...
被引量: 1 摘要: The invention relates to fertilisers containing magnesium sulphate and ammonium sulphate and to a process for their preparation. The magnesium sulphate exists in these fertilisers in the form of a double salt with the ammonium sulphate.收藏...
Worldwide the increasing use of inorganic nitrogenous fertilizer becomes a threat to the environment and consequently to the mankind. It is high time to think about the alternate nitrogenous source for assuring sustainable agriculture. Biological nitroge
atmospheric nitrogen and hydrogen by the Haber-Bosch method, a process that Fritz Haber developed about 1909 and which soon after was adapted for large-scale production by Carl Bosch. Commercially produced ammonia is used to make a wide variety of nitrogen compounds, including fertilizer and ...
Mulching and/or mineral fertilizer significantly influenced fruit quality attributes and proportion of fruit for exportation (Figure 3 and Figure 4). Mulching had significant effects on infructescence length (p = 0.008) and fruit weight (p = 0.002). Infructescence length was higher with burying ...
