“…Because organic manure is rich in nitrogen, the application of organic manure could significantly improve soil nitrogen (Figure 3), which is consistent with the research results reported by Long et al [47] and Ashraf et al [9]. However, the TP content of OM treatment was slightly lower than that of other treatments, which was contrary to the past research results of some other scholars [48,49].…”

The input of exogenous organic materials is an effective way to improve soil organic matter (SOM) content in cropland. The exploration of the impact of new organic materials such as woody peat on black soil fertility can provide an important reference for preventing the degradation of black soil in Northeast China. In this study, the effects of adding woody peat to SOM and the soil-integrated fertility of black cropland were studied by seven treatments (no organic matter addition, CK; crop straw returning, SR; decomposed straw addition, DS; organic manure addition, OM; 6 t/ha woody peat addition, LWP; 10.5 t/ha natural humus material addition, MWP; and 15 t/ha natural humus material addition, HWP). The results show that natural humus material additions (LWP, MWP, and HWP treatments) could significantly increase SOM (increased by 4.79~9.41 g/kg), labile SOM (increased by 2.49~4.52 g/kg), and recalcitrant SOM (increased by 2.13~6.39 g/kg) components, respectively. For comparison, traditional organic material inputs (SR, DS, and OM treatments) had no significant effect on SOM but induced an increase in the labile SOM component in the following year. This study also found that natural humus material additions could improve soil-integrated fertility in a year term, especially in promoting SOM accumulation. However, organic manure amendment showed both the advantage of increasing soil fertility slightly and the disadvantage of increasing soil salt sharply. In conclusion, compared with traditional exogenous organic materials, the natural humus material amendment technique can rapidly increase the total SOM quantity and its different stability components and has a great effect in improving the integrated fertility of black soil. Thus, it is of significance to further study the potential of natural humus material amendment in the fertility of black soil in future.

“…Among these, soil nutrients strongly influence the quality of cultivated land. Available phosphorous (AP) and available potassium (AK) have a higher weighting as they primarily drive cropland soil health at the microscopic soil nutrient level (Jin et al., 2023). AP is the inorganic form of TP and is easily absorbed and utilized (Cheng et al., 2023).…”

In light of growing concerns regarding food security and soil health, there is increasing emphasis on the assessment of soil health and efforts to improve or maintain the soil health of cultivated land. This case study Niutian Town in Jiangxi Province in southern China was selected as a typical red soil and a major grain‐producing area. This research involves an integrated evaluation model based on Entropy weight TOPSIS and emergy analysis to assess the soil health of cultivated land. An evaluation system was developed, comprising 31 indicators selected on the basis of resources and environments, with an emphasis on sensitive and promising microorganisms category indicators. Additionally, experiments were conducted to assess the ecological risk of soil pollution and develop novel soil conditioners. Our results indicate that Pb, Hg and Cd present a moderate ecological risk on 92.1% of the cultivated land. Furthermore, 56.8% of the cultivated land was ‘sub‐healthy’ or ‘unhealthy’. Biochar was found to be a soil conditioner with a good adsorption effect, with absorption rates reaching up to 99.9% and 88.3% for Pb and Cd, respectively. Additionally, g‐C3N4 was added to address pesticide contamination, which showed an adsorption rate of up to 75.2% for atrazine. This work develops a targeted remediation approach based on assessment results to address regional cropland soil health issues.

“…Previous studies have suggested that partial organic fertilizer treatments tend to result in higher available P levels, which differs from the results of this study. The monitoring of soil runoff indicated that soil available P loss under chemical fertilizer treatment was much higher than organic fertilizer treatment, and soil P loss and degree of P saturation (DPS) decreased significantly with 30% manure substitution, reducing the risk of P loss ( Li et al., 2021a ; Jin et al., 2023 ). However, this study was conducted in a closed environment with minimal P loss.…”

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.
