“…A previous study reported stable SOM reported under a minimum tillage system [ 43 ]. Similar to the findings of this study, Cao et al [ 44 ] reported increased recalcitrant NaOH-Po under maize stover retention co-applied with NPK. The higher residual P under MTCrGF probably was due to the transformation of P fractions (from stover residues, goat manure, and inorganic fertilizer), resulting in a build-up of residual P and occluded within soil micro-aggregates.…”

A large number of studies suggested that biochar can affect the adsorption of phosphorus (P) in soil and the distribution of P in soil aggregates, but it is still unclear whether biochar can indirectly affect the distribution of P in soil profiles through the influence of these two factors. Therefore, the ability of maize straw biochar to mitigate the risk of loss of P and improve the distribution of P in soil profile was evaluated by studying the capacity of soil to adsorb P from the soil and distribution fractions of it in diverse grain‐sized aggregates of soil. A 5‐year field trial site had received NPK fertilizer inputs at the same rate and one‐time biochar inputs at different rates (0, 15.75, 31.5 and 47.25 t ha−1) at the beginning of the experiment. Langmuir and Freundlich equations were fitted to the sorption data of the soil and suggested that the applicataion of biochar can promote P absorption capacity of soil, particularly when the rates of biochar applied were 31.5 and 47.25 t ha−1. Biochar can improve the stability of soil aggregates, and aggregates with particle sizes of 0.25–2 mm have the highest relative rate of contribution to various fractions of P in the soil. Biochar can promote the accumulation of most of the P fractions in soil aggregates, particularly when the rates of biochar applied were 31.5 and 47.25 t ha−1. The TP, Ca2‐P, Al‐P, Ca8‐P, moderately labile organic phosphorus (MLOP) and moderately resistant organic phosphorus (MROP) were primarily distributed in the 0–20 cm soil layer. Biochar increased the contents of MLOP and highly resistant organic phosphorus in the soil layer of 0–20 cm while reducing the contents of Al‐P, Fe‐P and occluded phosphorus (O‐P) in the soil layer of 0–20 cm and decreased the contents of TP, Ca8‐P, O‐P and MROP under the 20 cm soil layers. Biochar can change the distribution of P fractions along the soil profile by improving the adsorption of soil P and its distribution in the soil aggregates (0–20 cm).

“…The non-labile P fractions which are stable and insoluble P form, such as occluded P (O-P) and apatite P (Ca 10 -P), are known as the unavailable P pools for plant uptake (Cao et al, 2020). The Ca 10 -P fraction is dominated by all the P fractions in the soils.…”

Phosphorus (P) constraint can be alleviated by increasing C inputs, which can help to improve crop production and P fertilizer use efficiency. However, the effects of different manures on soil microbial biomass P (MBP) and P fractions as well as C fractions in calcareous soils remain poorly understood. Soil MBP pool involves the P mineralization and immobilization processes, potentially changing P fractions and P availability. Therefore, the effects of different manures on soil microbial biomass (MBP, MBC) pool, P, and C fractions and crop P utilization were evaluated in greenhouse experiments with maize plantation. Treatments included no manure (control), poultry manure (PM), cow manure (CM), goat manure (GM), mixed manure (MM), and three inorganic P (Pi) rates; P0: 0 mg kg-1, P50: 50 mg kg-1, and P100: P100 mg kg-1 (P2O5). For plant growth comparison, crop physiological growth indices, shoot P contents and total P uptake were increased by PM and P100 as compared to other treatments. The PM with P100 significantly increased the plant growth by inducing P uptake of ∼18% compared with control. The results exhibited that Pi (P100) combined with manure (PM) significantly (p < 0.05) increased the soil physicochemical properties, that is, 683.76 mg kg-1 total P, 21.5 mg kg-1 Olsen P, 4.26 g kg-1 SOC, 2.41 g kg-1 POC, as well as microbial biomass C and P increased by 152.84 mg kg-1 and 36.83 mg kg-1, respectively. Consequently, we concluded that PM with Pi (P100) application builds up soil microbial biomass, which is more beneficial for promoting P utilization for maize.
