“…Furthermore, due to the presence of large SSA with complex functional groups, biochar is able to bind several soil nutrients, and thus prevent the leaching loss of nutrients. Ukwattage et al (2020) reported that there was almost 50% reduction in leaching loss of P when biochar was applied in a subtropical sandy Ultisol, due to the fixation of P in biochar matrix.…”

“…However, the rapid migration of 20-nm n-HAP results in greater loss of P. The present study showed that the 20-nm n-HAP had 13.43% wastage of available P in the soil after elution, which was far more than that of the 200-nm and 80-mm HAP treatments. Recent research found that coal fly ash and biochar showed synergistic effects in reducing the leaching loss of P (Ukwattage et al, 2020), which may offer a solution.…”

“…Greater environmental awareness and the demand for higher P availability have prompted researchers to focus on the effective utilization of P fertilizers in agriculture (Jiao et al, 2012). In addition, leaching is regarded as an important means of transporting P through the soil (Ukwattage et al, 2020).…”

Low mobility and solubility reduce the availability of traditional phosphorus (P) fertilizer in red acidic soil. Hydroxyapatite (HAP), especially nano-hydroxyapatite (n-HAP), may be more efficient than P fertilizer because of its nanoparticle characteristics. Camellia oleifera (C. oleifera) is an edible oil tree whose productivity is greatly affected by P fertilizer. During this study, we investigated the migration of different particle sizes of HAP (20 nm, 200 nm, and 80 μm) and their effects on the seedling growth of C. oleifera cultivar Huashuo (HS) cuttings. A column experiment showed that the efflux ratio was negatively correlated with particle size in red acidic soil. The leaching results revealed that the contents of total P and available P in the 20-nm treatment were significantly higher than those in the 200-nm and 80-μm treatments in the deep soil (10–15 cm or 15–20 cm), whereas the application of 20-nm n-HAP caused 13.43% wastage of available P. During the container experiments, 200-nm and 20-nm HAP significantly promoted the growth of the seedlings in terms of seedling height, stem diameter, and biomass. The available P contents in the rhizosphere and nonrhizosphere soils were negatively correlated with the HAP particle sizes. In conclusion, the migration of HAP is inversely correlated with particle size, and HAP improves the P bioavailability in red acidic soil. In summary, 200-nm HAP was the best P fertilizer for the seedlings of HS among the three particle sizes. This study offers preliminary results indicating that 200-nm HAP might be a better P fertilizer compared with other two HAP particle sizes for use in future C. oleifera orchards.

“…This is because oyster shell powder can strengthen the adsorption and retention of the fertilizer in the soil due to its own porous structure, reduce the fertilizer entering the liquid phase in the soil, inhibit the loss of nutrients, and improve the utilization rate of the fertilizer. The application of biochar, in terms of soil nutrient leaching, has become a hot research topic (Rubin et al 2020;Ukwattage et al 2020;Partovi et al 2021); there are also a few reports on the practical application of oyster shell powder in this field. Biochar can reduce soil nutrient leaching loss through adsorption and the formation of aggregates in the soil (Xiao and Meng 2020), but the adjustment of acidity is not as obvious as that observed by the application of waste oyster shell powder, nor can it supplement Ca 2+ in the soil simultaneously.…”

In this study, we analyzed the effect of oyster shell powder of different proportions on the nutrient leaching characteristics of latosol, using an indoor soil column simulation test. Based on the optimized fertilizer application amount, we tested five different amounts of oyster shell powder in the test [0 % (control, CK), 0.1 % (T1), 0.2 % (T2), 0.4 % (T3), and 0.8 % (T4)] for analyzing the intermittent and dynamic leaching characteristics of nutrients in the soil samples. The results indicated that the loss of nutrients in urea, superphosphate, and potassium chloride (due to leaching) increased linearly with the amount of fertilizer. By adding oyster shell powder, the leaching loss reduced by 23.90–57.25 % for ammonium nitrogen, 6.31–10.07 % for phosphorus, and 17.08–26.58 % for potassium. However, the leaching loss for nitrate nitrogen increased by 2.5–5.8 times. In addition, the application of oyster shell powder to latosol provided acid adjustment and water retention enhancement, which increased the pH value of the soil by 3.77 (from pH 4.15 to 7.92) and reduced water loss by 2.52 %. Thus, the application of oyster shell powder can reduce the acidity of the surface soil and retain water and fertilizer to a certain extent; however, it may increase the potential risk of nitrate nitrogen pollution in groundwater.
