The Green New Deal requires a profound transformation of the agricultural sector, which will have to become more sustainable and ensure universal access to healthy food. Thus, it will be essential to introduce radical technological innovations. Nanotechnologies have the potential to produce a significant boost to the improvement of the food system. Within this context, in the next years, a strong challenge will need to be faced regarding developing new and more efficient uses of nutrients in agriculture, being the nutrient use efficiency (NUE) paramount in sustaining high crop productivity without depleting biodiversity, and altering both the natural and agricultural systems. Nutrients leaching causes environmental pollution and water eutrophication, while nutrient excess favors pest and weed widespread. Therefore, it will be mandatory to improve plant nutrition efficiency without affecting agricultural productivity and economic sustainability. A promising alternative consists of the introduction of the so-called nanomaterial enhanced fertilizers and plant growth stimulators. Such innovation includes nanotechnological solutions that can improve nutrient delivery for a more finely tuned, accurate, and saving-resources distribution of nutrients. This review provides a critical view of the latest advances in nanofertilizer research, mainly referring to nano-hydroxyapatite, silica nanoparticles, and chitosan-derived nanostructures.

“…The urea loaded hydroxyapatite nanocarrier delivers plant nutrients efficiently for rice production therein. Urea doped hydroxyapatite nanoparticles (Ur@HANP) was also tested in sand columns and agricultural soil for understanding the retention capacity of plant nutrients. , A combination of faster and slow release behavior of nutrient release attains an equilibrium after a well-defined number of days which was witnessed for mesoporous silica nanoparticles (MeSiNPs) with a water-soluble N-polymer . The Fe II content of ≥37 mg kg –1 in rice plants (on a dry weight basis) at 60 days after sowing was found to be a guide value for monitoring the Fe-nutrition status of rice .…”

Driven by the possibility of precise transformational change in nutrient-enrichment technology to meet global food demand, advanced nutrient delivery strategies have emerged to pave the path toward success for nutrient enrichment in edible parts of crops through bioderived nanocarriers with increased productivity. Slow and controlled release of nutrient carrier materials influences the nutrient delivery rate in soil and in the edible parts of crops with a sluggish nutrient delivery to enhance their availability in roots by minimizing nutrient loss. With a limited understanding of the nutrient delivery mechanism in soil and the edible parts of crops, it is envisaged to introduce nutrient-enrichment technology for nutrient delivery that minimizes environmental impact due to its biodegradable nature. This article attempts to analyze the possible role of the cellulose matrix for nutrient release and the role of cellulose nanocomposites and nanofibers. We have proposed a few cellulose derived biofortificant materials as nutrient carriers, such as (1) nanofibers, (2) polymer–nanocellulose–clay composites, (3) silk-fibroin derived nanocarriers, and (4) carboxymethyl cellulose. An effort is undertaken to describe the research need by linking a biopolymer derived nanocarrier for crop growth regulation and experimental nitrogen release analysis. We have finally provided a perspective on cellulose nanofibers (CNFs) for microcage based nutrient loading ability. This article aims to explain why biopolymer derived nutrient carriers are the alternative candidate for alleviating nutrient deficiency challenges which are involved in focusing the nutrient delivery profile of biopolymers and promising biofortification of crops.

“…As a result, it is critical to investigate innovative P fertilizers, not only to improve fertilizer utilization efficiency but also to reduce negative environmental impacts. To address this, due to their unique physicochemical properties that aid in efficient uptake by plants, P-based nanofertilizers may be a solution to the challenges with existing bulk fertilizers [ 1 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ].…”

“…Recently, nanoformulations of hydroxyapatite (nHAP) have started gaining attention to be explored for agricultural applications. Early research has been limited to studies that use nHAPs as a base or carrier to deliver other macronutrients (N and K) by its surface modification using most prominently urea [ 14 , 18 , 19 , 20 ], zeolite [ 17 ], humic acid [ 21 ] and cellulose [ 22 ]. Another use of nHAP has been restricted to their bioremediation application by immobilizing heavy metals such as lead in agricultural soils [ 23 , 24 ].…”
