“…In agreement with our results, other studies report that the addition of organic fertilisers does not change total Po (Annaheim et al, 2015;Jantamenchai et al, 2022). As the total Po balance was not affected by adding compost, either in surface or subsurface soils, we suggest that the increases in EDTA-NaOH-Po and NaHCO 3 -Po in the organic C-depleted compost-amended soils may indicate an increase in mobilization of retained Po.…”

“…Agricultural management practices can affect P availability and Po pools (Faucon et al, 2015;Foereid, 2017;Cooper et al, 2018). Increases in Po have been found in minerally fertilised soils after applying P mineral fertilisers alone or combined with manures (Li et al, 2022a), whereas, in other studies, no signi cant changes were observed after applying only manures or plant residues (Annaheim et al, 2015;Jantamenchai et al, 2022). Increasing organic matter in soil favours Pi mobility (Haynes and Mokolobate, 2001), but its effects on Po pools are less clear.…”

“…Arable mineral soils typically contain a signi cant proportion of organic phosphorus (Po), varying from 20 to 80% of the total phosphorus (Dalal, 1977;Jantamenchai et al, 2022). In some cases, the Po exceeds inorganic P (Pi).…”

Background Microbiota can favour crop access to phosphorus (P) pools retained in soil. Microbial activity and P mobilization can be enhanced by soil carbon and root exudates.Aims We aimed to study the changes in organic and inorganic P (Po; Pi) forms and compounds in organically fertilised soils growing crops for two years.Methods Crops were grown in pots with compost added at the soil surface. We measured changes in microbial carbon, soluble carbon, total Po and Pi forms, the less labile EDTA-NaOH-Pi (-Po), and labile NaHCO3-Pi (-Po) in surface and subsurface soils from crop-free pots amended with compost and unamended, and from amended pots growing crops. P compounds in the EDTA-NaOH extract were measured by 31P-NMR.Results Compost addition increased the levels of Pi and although it had no effect on Po it increased inositol hexakisphosphate and other-monoesters. After the application of compost, the amount of total organic carbon, soluble carbon and P forms increased in surface soil, while in the subsurface soil there was a reduction in organic carbon and an increase in soluble carbon, total Pi, EDTA-NaOH-Pi and NaHCO3-Pi and the less labile EDTA-NaOH-Po and labile NaHCO3-Po. Growing crops reduced all measured Pi forms and had no observable impact on total Po in either organic C-enriched or organic C-depleted soils.Conclusions Crops mostly used Pi from the low P availability C-depleted layer. Large reductions in NaHCO3-Po and increased levels of other-monoesters in crop growing organic C-enriched layers may suggest microbial mobilization and crop use of this pool.

“…At each point, three soil samples were collected at a depth from 0 to 5 cm (the phase spacing between each sampling location was 1 m) (Figure 1b) and then mixed them together as one sample. “The collected soil samples were air dried and passed through a 2‐mm mesh; thereafter, the physical and chemical properties were measured.” (Metawee et al, 2021) “Soil organic matter (SOM) was determined via the potassium dichromate method” (Bao, 2000). In addition, before examining the particle size, the soil samples have been pretreated by using chemical disperse; the laser diffraction technique was employed to examine the particle size of the collected samples by using an Analysette 22 NanoTec instrument with the measurement interval being [0.01, 2100] (Fritsch Instruments, Fritsch, Germany), and the results were classified based on the international particle size classification method.…”

In order to explore the influence of vegetation on homogeneity of surface particle size distribution (PSD) and heterogeneity of soil structure, observations, theory, and multifractal results were synthesized to highlight the evolution of the soil particle composition in the Jilantai Salt Lake Protection System (Jilantai system) after long‐term wind‐sand activities and its soil structure characteristics. From flowing sand dune to saline‐alkali wasteland areas, the mean grain size and surface particle sorting degree gradually increased and decreased, respectively, whereas the shape of the particle frequency curve gradually changed from extremely positive deviation to negative deviation, and the peak shape of the curve gradually changed from narrow to wide. Furthermore, the inhomogeneity of the soil particle composition gradually decreased, whereas the range of the soil PSD gradually increased, and the soil increasingly became fine‐grained. Therefore, the contents of clay and silt in shelterbelt soil increased by 16% and 18.36%, respectively, over 1986 levels. Additionally, clay and silt play a vital role in determining soil particle parameters such as standard deviation (SD), skewness (SKI), and monofractal (D), while vegetation factors are the main controlling factors of clay and silt. In conclusion, the Jilantai system could increase heterogeneity and homogeneity and decrease the concentration of soil PSD by changing the sedimentary environment, while this affect depends largely on the fractional vegetation cover, vegetation height, and light penetrating porosity. Moreover, the multifractal and particle parameters could describe the soil structure characteristics and sedimentary process, respectively, after long‐term wind‐sand activities.

Organic fertilization in no‐till soils increases soil organic matter and nutrient pools primarily in surface soils. However, little is known about how microbial activity affects crop access to phosphorus (P) forms at the surface, where the organic fertilizer is applied, and the subsurface, the main rooting zone. We aimed to study the changes in organic and inorganic P (Po; Pi) forms and compounds in no‐till compost amended surface (0–5 cm) and subsurface (5–15 cm) soils growing a crop rotation for 2 years in pots. Crops were grown in pots with compost amended to the soil surface, while unamended and compost‐amended pots without crops were used as controls. We measured changes in microbial C (carbon), soluble C, total Po and Pi forms, the moderately accessible EDTA‐NaOH‐Pi (‐Po), and labile NaHCO3‐Pi (‐Po). P compounds in the EDTA‐NaOH extract were measured by 31P‐NMR. Compost addition increased the levels of total Pi and although it had no effect on total Po, increases of inositol, other phosphate monoesters and orthophosphate diesters could be observed. After the application of compost, the amount of total organic C, soluble carbon and all P forms increased in surface soil, while in the subsurface soil, there was a reduction in organic C and an increase in soluble C, total Pi, EDTA‐NaOH‐Pi and NaHCO3‐Pi and the EDTA‐NaOH‐Po and labile NaHCO3‐Po. Growing crops reduced all measured Pi forms and labile NaHCO3‐Po, increased EDTA‐NaOH‐Po in surface soils and had no observable impact on total Po in either organic C‐enriched surface or organic C‐reduced subsurface soils. Crops mostly used Pi from the low P availability C‐reduced subsurface layer, where NaHCO3‐Po pools also decreased. Large reductions in NaHCO3‐Po and increased levels of IHP and other‐monoesters in crop‐growing organic C‐enriched surface layers may suggest microbial formation of monoesters Po and crop use of labile Po pools. In summary, Po formation in C‐enriched surface layers and the mobilization of all Pi forms throughout the soil profile are particularly important findings for the understanding of P dynamics in compost‐amended no‐till systems.
