“…Heavy metals may enter into the soil, plant system and food chain due to excess application of fertilizer and that is a great threat to lives [3]. The total demand for nitrogen worldwide is calculated to be 112.9 million tons in 2015 and about 60-75% of nitrogen is utilized in the fertilizers industry [4]. Therefore, the extended presence of commercial fertilizer pollutes both underground and surface water causing nitrate contamination and eutrophication.…”

In this research work, we propose macronutrients incorporated slow-release based nano-fertilizer using nanozeolite as a carrier. A simple chemical approach was used to synthesis the proposed nanozeolite composite fertilizer (NZCF). To gain an insight into the properties, morphology and structure of the synthesized NZCF, it was further characterized by different techniques such as powder XRD, FT-IR, SEM, and TG/DTA. A considerable enhancement of the quality and the water retention capacity of the soil was observed as a result of applying the proposed NZCF when compared with a commercial fertilizer. Furthermore, the swelling ratio and the equilibrium water content of NZCF were compared to the commercial fertilizer and their effect on plant growth was observed. Slow-release studies were carried out for both NZCF and the commercial fertilizer. The results of these studies reveled that NZCF possessed a long-term release pattern of the macronutrients and that showed a great potential for promoting plant growth. Hence, the prepared nanocomposite fertilizer can be safely used as an environmentfriendly source of nutrients to enhance plant growth.

New advances in nanotechnology are driving a wave of technology revolution impacting a broad range of areas in agricultural production. The current work reviews nanopesticides, nano-fabricated fertilizers, and nano activity-based growth promoters reported in the last several years, focusing on mechanisms revealed for preparation and functioning. It appears to us that with many fundamental concepts have been demonstrated over last two decades, new advances in this area continue to expand mainly in three directions, i.e., efficiency improvement, material sustainability and environment-specific stimulation functionalities. It is also evident that environmental and health concerns associated with nano agrochemicals are the primary motivation and focus for most recent work. Challenges and perspectives for future development of nano agrochemicals are also discussed.

“…Water retention experiments (WR) were conducted in pre-weighted cups, add 50 g of sieved soil in cup A (W A ) as control or blank and in cup U, X and Y (W U , W X and W Y , respectively) add 2 g of urea, SRUFX and SRUFY into the cups respectively with 50 g soil and then, 30 ml of distilled water was added in each cup, allowed to contact and reweighed after 24 h (weighed as W A1 , W U1 , W X1 and W Y1 ). The cups were then retained in a glass box, weighted on daily basis for 30 days (weighed as W A2 , W U2 , W X2 and W Y2 ) (Hamid et al, 2013;Lateef et al, 2019). Water retention was calculated using Eq.…”

The increasing usage of slow release fertilizers has become an essential demand to save fertilizer consumption and reduce the environmental pollution. In this study, two different techniques were used to prepared slow release urea fertilizers (SRUFX and SRUFY) composed of urea, sawdust and gelatin as a binding material. The two prepared fertilizers were characterized by Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray (EDX) and X-Ray diffraction (XRD). Urea static release was studied and indicated a prolongation of the release pattern of urea with approximately three times by incorporating saw dust and gelatin. The kinetics of the static release showed that SRUFX and SRUFY follow non-fickian release. The effect mechanical stress (1, 1.5 and 2 MPa) on the release time of urea was studied and indicated an increase in time of release as the stress increases.
