“…In addition, significant amounts of inorganic and organic nutrients are released into the environment, which is reflected by high chemical oxygen demand (COD) and biological oxygen demand (BOD). Eutrophication of aquatic environments caused by excessive loadings of phosphorus (P) and nitrogen (N) results in environmental concerns such as the generation of solid wastes and unpleasant emissions to the air [ 2 , 3 ]. It also promotes the growth of unwanted microbes that threaten other aquatic life and deteriorate the quality of drinking water, which contributes to common health-related issues in regions neighboring the discharge area [ 4 ].…”

“…Extensive fertilization using traditional chemical fertilizers may be lost from the top soil by leaching to reach water bodies, accordingly these practices lead to poor nutrient use, whereas controlled-release fertilizers could be more advantageous compared to conventional fertilizers (Vejan et al 2021). The global demand for mineral fertilizers (including NPK) was estimated by 185.06 million tons in 2016, and is predicted to increase up to 200.92million tons in 2022 (Wang et al 2022). Several studies have been recently published on controlling the release of fertilizers or so-called nano-fertilizers and their prospective in increasing crop production (e.g., Shams and Abbas, 2019;Madzokere et al 2021;Beig et al 2022;Bhardwaj et al 2022;Dhlamini et al 2022;Jakhar et al 2022;Wang et al 2022), but the impacts of nano-fertilizers on environmental compatibility, crop quality, and non-targeted organisms need further research (Vejan et al 2021).…”

UE to the rapid population growth, global food production should be increased to meet this global demand. Agriculture is considered the main dominant channel of food supply and any approach that support the crop productivity is urgent. These agro-practices may include using the high-yield varieties, improving rational irrigation and fertilization. It is noticed that, using of chemical or mineral fertilizers in agricultural production dramatically increased global food production. Several negative impacts have been recorded worldwide on the environment, which resulted from leaching of nutrients into groundwater, beside the low efficiency of applied fertilizers. Applying of nanofertilizers, is a promising approach, and an effective technology, which can increase sustainability and efficiency of agro-production of cultivated crops because of their nano-size properties, their high nutrient use efficiency, their slow release of nutrients, and thereby low required applied dose of fertilizer. Smart fertilizer means the control dose and time of applied fertilizers using the smart agro-technological and advanced tools such as global positioning systems, and remote sensing. These tools are able to maximize crop yield and minimize agro-chemical inputs by precise monitoring of the environment. Therefore, this work is a comparison between smart fertilizer and nanofertilizer, and to answer the main question: are the bio-nanofertilizers considered emerging precision agriculture strategy? This is also a call by Environment, Biodiversity and Soil Security (EBSS) for receiving articles on smart fertilizer, under many related topics such as different applications of smart fertilizers in smart agriculture, their challenges, their obstacles and the novel solutions in this concern.

“…Phosphorus is necessary for early plant growth and development because of the need for rapid cell division [10,11]. Plants may absorb P either as primary monobasic phosphate (H 2 ) ions or small amounts of the secondary dibasic phosphate (HPO 4 2-) ions and the phosphate (PO 4 3-) ions [12,13]. Phosphorus has poor solubility, and phosphorus fertilizers suffer from low availability of soluble phosphorus for plant uptake.…”

“…e unique properties of biochar provide a platform for loading nutrients to improve fertilizer efficiency. Conventional chemical fertilizers suffer from the drawbacks of rapid nutrient leaching, serious environmental pollution, and significant economic burden, and biochar-based slow release of fertilizers receives increasing global attention [13]. Most soils in the tropics, with Cameroon inclusive, suffer from a limited supply of P due to the presence of oxides and hydroxides of iron and aluminium in these soils that fix the soluble P, and this process is accelerated by low soil pH.…”

This study evaluated the physicochemical properties and phosphorus adsorption characteristics of surface soils (0–30 cm) of Meupi on the flank of Mount Lefo-Awing. In volcanic-influenced soils, usually characterized by high acidity, phosphorus is often not readily available to plants, and this deficit tends to limit plant growth. Soil physicochemical properties and phosphorus adsorption studies were carried out using standard techniques. Results of soil physicochemical studies showed that the soils were strongly acidic (pH ranged from 4.7 to 5.1), with low available phosphorus (5.47 to 6.97 mg/kg). The apparent equilibrium time for phosphorus to be adsorbed in the analyzed soils was 24 hours. Phosphorus sorption studies revealed that the rate of phosphorus adsorption increased with an increase in the concentration of added phosphorus but decreased at a certain level at higher concentrations because the soil had no more capacity to adsorb phosphorus. The degree of fitness (R2) of the phosphorus adsorption data for the different adsorption models was in the order Langmuir < Temkin < Van Huay < Freundlich. This suggested that the Freundlich isotherm model was the best fit to describe P sorption processes in soils. The pseudo-second-order kinetics model, which assumed that the rate of phosphorus sorption was dependent on the number of active sites, gave a good fit to predict and describe the kinetics of phosphorus sorption from the soil solution. The capacity of the soil to adsorb phosphorus significantly correlated positively with amorphous Fe (r = 0.953 and p < 0.05 ), free Fe (r = 0.984, 0.976 and p < 0.05 ), free Al (r = 0.994 and p < 0.01 , r = 0.988 and p < 0.05 ), and clay (r = 0.968 and p < 0.05 ), which were the main parameters considered as predictors of phosphorus adsorption activities in the soils.
