granular fertilizer grade calcium ammonium nitrate

Composition:granular fertilizer grade calcium ammonium nitrate , nitrogen (N) 27 % (ammonia N (N-NH4) - 13.5 %, nitrate N (N-NO3) - 13.5 %), magnesium (MgO) - 4.0 %, calcium - 6.0 %.

Fertilizing effect: nitrogen is absorbed easily and efficiently. Calcium and magnesium are important to plant vital functions. Calcium ammonium nitrate enables plants grow wide leaves of rich green colour; provide 5 - 20 % richer harvest. Long-term usage causes no soil acidification and makes no impact on soil biological activity. Plants are enriched not only with nitrogen but also with magnesium and calcium. Moreover, calcium ammonium nitrate by providing plants with necessary nutrients compensates lack of light and the damage of acid soil.

Calcium ammonium nitrate (CAN) is a widely available fertilizer composed of ammonium nitrate mixed with some form of calcium carbonate such as limestone or dolomite. CAN is also frequently used to make homemade explosives. The potential of using elemental profiling and chemometrics to match both pristine and reprocessed CAN fertilizers to their factories for use in future forensic investigations was examined. Inductively coupled plasma-mass spectrometry (ICP-MS) analysis was performed on 64 elements in 125 samples from 11 CAN stocks from 6 different CAN factories. Fisher ratio, degree-of-class-separation, and partial least squares discriminant analysis (PLSDA) were used to develop a modelmore » using the concentrations of Na, V, Mn, Cu, Ga, Sr, Ba and U to classify a validation set of CAN samples into 5 factory groups; one group was two factories from the same fertilizer company. In terms of the pristine CAN samples, i.e., unadulterated prills, 64% of the test samples were matched to their correct factory group with zero false positives. The same PLSDA model was used to correctly match 100% of the CAN samples that were reprocessed by crushing and mixing the CAN with powdered sugar. In the case of crushed CAN samples mixed with aluminum powder, correct matches were made for zero to 100% of the samples depending on the factory the CAN originated. Remarkably, for one factory, 100% of the ammonium nitrate samples that were extracted from CAN using tap or bottled water were matched to the correct CAN factory group. Lastly, the water-insoluble (calcium carbonate) portions of CAN provided a greater degree of discrimination between factories than the water-soluble portions of CAN. In summary, this work illustrates that sourcing unadulterated CAN fertilizer can potentially be done with high frequency and high confidence using elemental profiling and chemometrics while the sourcing of reprocessed CAN is dependent on how much an adulterant alters the recovered elemental。Calcium ammonium nitrate is suitable for fruits, vegetables and crops
