摘要

磷(P)是植物生长的重要养分，但由于其固结性和低溶解度，其在土壤中的有效性往往受到限制。有机改良被认为是提高土壤磷素有效性和作物生产力的有效策略。然而，对不同有机质类型、残留物质量和土壤生物物理条件对土壤磷动态和产量的影响进行综合量化的全球综合研究仍然有限。本荟萃分析基于232项同行评议研究的1076对观察结果，量化了oa对土壤有效磷（AvP）、全磷（TP）和作物产量的全球影响。平均而言,美洲国家组织显著增加了AvP 83.3 % (CI: 73.2 % -93.4 %)和TP 27.5 % (CI: 23.3 % -32.1 %),堆肥显示AvP获得最高(176.3 %;CI: 146.2 % -206.4 %),其次是肥料(135.6 %;CI: 109.8 % -161.4 %),生物炭(65.4 %;CI: 53.3 % -77.5 %),和稻草(30.8 %;CI: 17.4 % -44.2 %)。AvP的增加在低有机碳（<5 %,169.4 %）、碱性pH （>7, 164.8 %）和砂壤土（132.4 %）土壤中最为明显。OAs与化肥配施可使AvP进一步提高90.7 %，特别是与磷（158.3 %）和氮磷钾（122.1 %）配施。高碳（>300 g/kg）和高磷（>4 g/kg）、低碳氮比（≤20）和高碳磷比（>30）的残留物显著提高了AvP。作物产量提高36.4 %(生物炭;CI: 28.5 % -44.4 %),26.3 %(肥料;CI: 18.6 % -33.9 %),27.5 %(堆肥;CI: 21.9 % -33.1 %),和10.2 %(稻草;CI: 7.89 % -12.5 %)。AvP与作物产量呈中等正相关（R²= 0.25,P <； 0.01）。结构方程模型显示，残基C:P比是AvP增加的最强预测因子（通径系数= 0.40,P <； 0.001），AvP的增加进而提高作物产量（0.37,P <； 0.01）。这些发现表明，有机改良剂显著提高了土壤磷素有效性和作物产量，特别是在考虑残磷质量和特定土壤条件的情况下。

Organic amendment quality as a driver of soil phosphorus enrichment and crop yield: A global synthesis

Phosphorus (P) is a critical nutrient for plant growth, yet its availability in soils is often limited due to fixation and low solubility. Organic amendments (OAs) have been proposed as an effective strategy to enhance soil P availability and crop productivity. However, a comprehensive global synthesis quantifying the effects of different OAs types, residue quality, and soil biophysical conditions on soil P dynamics and yield remains limited. This meta-analysis, based on 1076 paired observations from 232 peer-reviewed studies, quantified the global effects of OAs on soil available P (AvP), total P (TP), and crop yield. On average, OAs significantly increased AvP by 83.3 % (CI: 73.2 %-93.4 %) and TP by 27.5 % (CI: 23.3 %-32.1 %), with compost showing the highest AvP gain (176.3 %; CI: 146.2 %-206.4 %), followed by manure (135.6 %; CI: 109.8 %-161.4 %), biochar (65.4 %; CI: 53.3 %-77.5 %), and straw (30.8 %; CI: 17.4 %-44.2 %). AvP gains were most pronounced in soils with low SOC (<5 %, 169.4 %), alkaline pH (>7, 164.8 %), and sandy loam texture (132.4 %). Co-application of OAs with fertilizers further increased AvP by 90.7 %, particularly with P (158.3 %) and NPK (122.1 %) fertilizers. Residue quality strongly influenced AvP: residues with high C (>300 g/kg) and high P (>4 g/kg) low C:N (≤20) and high C:P (>30) showed significantly higher AvP increases. Crop yield improved by 36.4 % (biochar; CI: 28.5 %-44.4 %), 26.3 % (manure; CI: 18.6 %-33.9 %), 27.5 % (compost; CI: 21.9 %-33.1 %), and 10.2 % (straw; CI: 7.89 %-12.5 %). A moderate positive correlation (R² = 0.25, P < 0.01) was found between AvP and crop yield. Structural Equation Modeling revealed that the C:P ratio of residues was the strongest predictor of AvP increase (path coefficient = 0.40, P < 0.001), which subsequently enhanced crop yield (0.37, P < 0.01). These findings demonstrate that organic amendments substantially improve soil P availability and crop yield, especially when residue quality and site-specific soil conditions are considered.

期刊介绍： Soil & Tillage Research examines the physical, chemical and biological changes in the soil caused by tillage and field traffic. Manuscripts will be considered on aspects of soil science, physics, technology, mechanization and applied engineering for a sustainable balance among productivity, environmental quality and profitability. The following are examples of suitable topics within the scope of the journal of Soil and Tillage Research: The agricultural and biosystems engineering associated with tillage (including no-tillage, reduced-tillage and direct drilling), irrigation and drainage, crops and crop rotations, fertilization, rehabilitation of mine spoils and processes used to modify soils. Soil change effects on establishment and yield of crops, growth of plants and roots, structure and erosion of soil, cycling of carbon and nutrients, greenhouse gas emissions, leaching, runoff and other processes that affect environmental quality. Characterization or modeling of tillage and field traffic responses, soil, climate, or topographic effects, soil deformation processes, tillage tools, traction devices, energy requirements, economics, surface and subsurface water quality effects, tillage effects on weed, pest and disease control, and their interactions.
