There have been several recent developments in slow-release fertilizers. These materials supply nutrients continuously over an extended period in contrast to water soluble fertilizers which are immediately available after incorporation in moist soil. Slow-release fertilizers are not subject to rapid leaching loss and do not easily burn plants from over-application. The major need for slow relea...

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...

Controlledrelease fertilizers (CRFs) offer an excellent option to improve nutrients uptake by plants and reduce the environmental hazards due to excess release of chemicals. Polymer-coated fertilizers, compared to the other types of CRF, are by far the most intensively researched topic because of their great characteristics. Polymercoated fertilizers, which are less sensitive to the soil and en...

Investigations of the plant food requirements for sugarcane grown on the wind-blown, sandy soils of marine origin typical of the Natal coast, have. occupied the' attention, of numerous investigat6rsin past 'years. In some cases there has been shown to be little response to phosphate, whilst in the case of inorganic salts of potash and nitrogen a lack. of response or even a depressing effect on ...
