Quantification of Ammonium Sulphate Nitrate (ASN) fertilizers
This paper shows a simple procedure for the quantification of industrial and laboratory samples of Ammonium Sulphate-Nitrate fertilizers (ASN) based on a Rietveld fit from X-ray powder diffraction profiles. The Rietveld fit is performed by means of the structural models of the double salts 2NH4NO3·(NH4)2SO4 and 3NH4NO3·(NH4)2SO4, previously reported by the authors. The proposed method demonstra...
متن کاملStudy regarding the influence of NPK fertilizers on the total nitrogen content from tomato ( Lycopersicum esculentum )
Nitrogen is an indispensable element for plants, being the fourth element as a percentage of plants by carbon, oxygen and hydrogen, in his absence they do not develop as a result of inhibition of chlorophyll synthesis and loss of nutritional values of fruits, hence the efficiency of this element in plans fertility of all plants. Conversely nitrogen (N), plants sensitizes the fall and decreases ...
متن کاملCadmium availability from granulated and bulk-blended phosphate-potassium fertilizers.
Recent field experiments have shown that high chloride (Cl) in irrigation waters can increase soil cadmium (Cd) uptake by crops because of the formation of soluble ion-pair complexes of Cd with Cl in soil solution. The present study was aimed at testing a hypothesis that KCl in granulated PK fertilizers may enhance Cd uptake by crops from Cd-containing P fertilizers because of close contact bet...
متن کاملpulse current efficiency in coating process of gold nanoparticles from potassium dicyanoaurate solution
comparison of the effects of two substrates and additives on pulse current electrodeposition of au nanoparticles showed that using indium-tin oxide instead of cu and cysteine instead of potassium iodide can improve morphology, current efficiency, photocatalytic effect and increase the number of nanocrystals. the examinations using the field-emission scanning-electron-microscope (fe-sem) showed ...
متن کاملEffect of N and NPK fertilizers on early field performance of narrow-leaved ash, Fraxinus angustifolia.
The effect of fertilization in the first growing season on early survival and growth of narrow-leaved ash (NLA) (Fraxinus angustifolia ssp. oxycarpa) was evaluated throughout the first 3 years of growth in Adapazari, Turkey. A randomized complete block design with four replications was established to investigate fertilization effects. Granular N urea [46%, (NH2)2CO, NH2-N] and NPK (15/15/15%; N...
