“…The intensity peak observed at 2θ values of 23.51, 25.7, 28.2 and 31.7 are corresponding to the low crystalline structure of nanozeolite. This finding supports previous XRD analysis of nanozeolite reported by Mohanraj et al [20]. The observed XRD spectrum is well-matched with the CCDC No-01-074-1183 of sodium aluminum silicate.…”

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.

Background: In the present study, redundant blanket applications of chemical fertilizer application to the soil set foot into the aquatic environment and cause eutrophication. Besides it cause low nutrient efficiencies, low organic matter, imbalanced fertilization and low fertilizer response influence to decrease crop yield. To solve this serious problem localized delivery of multi nutrients loaded with electrospun nanofibre through the seed coating approach. The nanofibre regulates the nutrient release at the targeted site (rhizospheric zone) in a sustained pattern of using e-spin technology. Methods: The electrospun carrier was developed from PVA at 10%, diameter of fibre ranges form (260 nm to 540 nm) was used as nanocarrier for encapsulate the multi nutrient at different concentration of 25, 50, 75, 100%. A field experiment was conducted during 2019-2020, to study the impact of crop response of MNC loaded nanofibre coated green gram seed. Result: It conclude that the novel nanofibre technology improve the higher plant height (47.38 cm) at maturity stage, total leaf area (1093.95), net assimilation rate (2.92 mg cm-2 day-1) at flowering stage, seed yield (883.41 kg ha-1) as compared to absolute control approaches. This nanofibre technology will give novel idea for the fertilizer industry owing to its unique larger surface area and controlled release kinetics.

“…Many a macronutrient fertilizers such as urea, which is a principal source of nitrogen in many parts of the world has a good water solubility and ready N availability to plants, but it also leads to loss of almost three-quarters of fertilizer nutrient during growth session, causing severe damage to the ecosystem [ 29 ]. Synthetic nitrogen fertilizers are the foremost contributors to nitrous oxide emissions and have been estimated to contribute as high as 20% to the world's total GHGs emissions [ 24 , 111 ]. The nutrients are very essential for plant growth in a balanced concentration but an excessive or imbalanced application can also cause toxicity to plants directly or affect indirectly by encouraging pathogens.…”

“…So, fertilizer management to minimize losses and improve use efficiency can be a promising strategy to surmount the issue of global climate change. In this direction, nanofertilizers have been reported to provide a better alternative [ 24 , 111 ]. Mohanraj et al [ 110 , 111 ] reported two studies with a significant decrease in GHG emissions in rice soil with the use of nano zeolite-based nitrogenous fertilizer containing NO 3 − and NH 4 + forms of N. The recorded size of the two forms was 66 nm and 77 nm for NO 3 − and NH 4 + , respectively, with an irregular shape.…”

Switching to nanonutrients for sustaining agroecosystems and environment: the challenges and benefits in moving up from ionic to particle feeding

The worldwide agricultural enterprise is facing immense pressure to intensify to feed the world’s increasing population while the resources are dwindling. Fertilizers which are deemed as indispensable inputs for food, fodder, and fuel production now also represent the dark side of the intensive food production system. With most crop production systems focused on increasing the quantity of produce, indiscriminate use of fertilizers has created havoc for the environment and damaged the fiber of the biogeosphere. Deteriorated nutritional quality of food and contribution to impaired ecosystem services are the major limiting factors in the further growth of the fertilizer sector. Nanotechnology in agriculture has come up as a better and seemingly sustainable solution to meet production targets as well as maintaining the environmental quality by use of less quantity of raw materials and active ingredients, increased nutrient use-efficiency by plants, and decreased environmental losses of nutrients. However, the use of nanofertilizers has so far been limited largely to controlled environments of laboratories, greenhouses, and institutional research experiments; production and availability on large scale are still lagging yet catching up fast. Despite perceivable advantages, the use of nanofertilizers is many times debated for adoption at a large scale. The scenario is gradually changing, worldwide, towards the use of nanofertilizers, especially macronutrients like nitrogen (e.g. market release of nano-urea to replace conventional urea in South Asia), to arrest environmental degradation and uphold vital ecosystem services which are in critical condition. This review offers a discussion on the purpose with which the nanofertilizers took shape, the benefits which can be achieved, and the challenges which nanofertilizers face for further development and real-world use, substantiated with the significant pieces of scientific evidence available so far.
