“…33,62 Integrated P management, such as integrating different types of mineral P fertilizers with soil-crop systems, as well as promoting shared responsibility and knowledge among stakeholders, can provide an effective approach for improving P use efficiency. 63,64 Furthermore, exploring the plant and microbial mechanisms associated with P acquisition strategies can also help to decrease the use of phosphate fertilizer in agricultural systems. 65 Hence, making improvements in matching and regulating the application of fertilizer-P with the key ecological factors will be a crucial research hotspot for achieving enhanced and sustainable rice production in China.…”

BACKGROUNDEfficient utilization of phosphorus (P) has been a major challenge for sustainable agriculture. However, the responses of fertilizer rate, region, soil properties, cropping systems and genotypes to P have not been investigated comprehensively and systematically.RESULTSA comprehensive analysis of 9863 fertilizer‐P experiments on rice cultivation in China showed that rice yield increased first and then fell down with the addition of P fertilizer, and the highest yield of 7963 kg ha−1 was observed under 100% P treatment. Under 100% P treatment, the yield response of applied P (YRP) and agronomic efficiency of applied P (AEP) were 12.8% and 30.1 kg ha−1, respectively. Lower soil pH (< 5.5) and organic matter (< 30.0 g kg−1) were associated with lower YRP and AEP. By contrast, soil available P < 25.0 mg kg−1 resulted in decreased YRP (15.3 to 11.4%) and AEP (32.3 kg kg−1 to 26.2 kg kg−1), whereas soil available P > 25.0 mg kg−1 maintained the relatively stable YRP and AEP. Also, the YRP and AEP were significantly higher for single‐cropping rice compared to other cropping systems. Moreover, the rice genotypes such as ‘Longdun’, ‘Kendao’ and ‘Jigeng’ had higher YRP and AEP than the average value. Overall, the fertilizer‐P rate was the primary factor affecting YRP and AEP, and the recommended P fertilizer rate can be reduced by 9–21 kg P ha−1 compared to existing expert recommendations.CONCLUSIONThe present study highlights the role of fertilizer‐P rate in maximizing the YRP and AEP, thereby providing a strong basis for future fertilizer management in rice cultivation systems. © 2023 Society of Chemical Industry.

“…The demand for P in crop production in China led to the rapid growth of the P fertilizer industry since the late 20th century ( Li et al., 2015 ). However, the extensive exploitation of P resources within a short timeframe has resulted in a depletion of these resources ( Liu et al., 2020b ; Gong et al., 2022 ). Notably, China annually produces approximately 5.7 billion tons of organic materials, equivalent to about 13 million tons of P 2 O 5 ( Niu and Ju, 2017 ), which are increasingly being utilized as substitutes for P in agriculture production, highlighting the importance of improving P recycling in agricultural waste for sustainable agriculture green development ( Yi et al., 2021 ).…”

IntroductionIn contemporary agriculture, the substitution of manure for chemical fertilizer based on phosphorus (P) input in vegetable production has led to a significant reduction in P fertilizer application rates, while, the effect of manure substitution rates on soil P transformation and uptake by root remain unclear.MethodsThis research conducts a pot experiment with varying manure substitution rates (0%, 10%, 20%, 30%, 40%, 50%, 75% and 100%) based on P nutrient content to elucidate the mechanisms through which manure substitution affects P uptake in pepper.Results and discussionThe result showed that shoot and root biomass of pepper gradually increased as manure substitution rate from 10% to 40%, and then gradually decreased with further increases in the substitution rate. Soil alkaline phosphatase activity and arbuscular mycorrhizal (AM) colonization gradually increased with manure substitution rates improvement. Specifically, when the substitution rate reached 30%–40%, the alkaline phosphatase activity increased by 24.5%–33.8% compared to the fertilizer treatment. In contrast, phytase activity and the relative expression of phosphate transporter protein genes in the root system was declined after peaking at 30% manure substitution. Additionally, soil available P remained moderate under 30%–40% substitution rate, which was reduced by 8.6%–10.2% compared to that in chemical fertilizer treatment, while microbial biomass P was comparable. In the current study, soil labile P similar to or even higher than that in chemical fertilizer treatment when the substitution rate was ≤40%. Correlation heatmaps demonstrated a significant and positive relationship between soil available P and factors related to labile P and moderately labile P.ConclusionThis finding suggested that substituting 30%–40% of chemical P with manure can effectively enhance root length, AM colonization, soil enzyme activity, soil labile P, and consequently improve P uptake in pepper. These findings provide valuable insights for future organic agricultural practices that prioritize P supply, aiming to standardize organic P management in farmland and achieve high crop yields and maintain soil health.
