Silicon alleviates ammonium toxicity in cauliflower and in broccoli
(2017-11-18)
Plant growth may be higher with a nitrate (NO3 −) and ammonium (NH4 +) ratio (N-A ratio), in relation to a particular form of N. However, the NH4 + can be toxic. In order to alleviate NH4 + toxicity in plants, silicon (Si) ...
New methods to quantify NH3 volatilization from fertilized surface soil with urea
(Sociedade Brasileira de Ciência do Solo, 2011-01-01)
Gaseous N losses from soil are considerable, resulting mostly from ammonia volatilization linked to agricultural activities such as pasture fertilization. The use of simple and accessible measurement methods of such losses ...

Accompanying ions of ammonium sources and nitrate : ammonium ratios in tomato plants
(2018-06-01)
The tomato (Solanum lycopersicum L.) cultivar Micro-Tom (MT) is widely used in physiological studies, but the effects of nitrate (NO3 -) and ammonium (NH4 +) ratios (NO3 - : NH4 + ratios) and, in particular, the effects ...
Effective participation of Li4(NH2)3BH4 in the dehydrogenation pathway of the Mg(NH2)2-2LiH composite
(Royal Society of Chemistry, 2016-06)
Lithium fast-ion conductors have shown positive effects on the hydrogen storage properties of the Li-Mg-N-H system. In the present work, Li4(NH2)3BH4 doped Mg(NH2)2-2LiH was formed by milling the 2LiNH2-MgH2-0.2LiBH4 ...
Tungstophosphoric acid heterogenized onto NH4NH4 ZSM5 as an efficient and recyclable catalyst for the photocatalytic degradation of dyes
(Sociedade Brasileira de Química, 2015-03-05)
Materials based on tungstophosphoric acid (TPA) immobilized on NH4ZSM5 zeolite were prepared by wet impregnation of the zeolite matrix with TPA aqueous solutions. Their concentration was varied in order to obtain TPA ...
