Research information on poultry manure's impact on soil characteristics, mineral composition and maize performance is scarce, despite the vital role nutrient levels play in supporting human health. The objective of this study was to examine the effects of poultry manure on soil properties, grain mineral content, growth, grain yield and economic benefit of maize. A two-year field experiment (2022-2023) was conducted at the Teaching and Research Farm of Adekunle Ajasin University, Akungba-Akoko, Ondo State using five poultry manure levels (0, 5, 10, 15, and 20 t ha⁻) in a randomized complete block design with three replications. Poultry manure significantly reduced soil bulk density and improved porosity, moisture content, chemical properties, and grain mineral composition. Maize growth and yield increased with higher manure levels, but the 10 t ha⁻ treatment produced the best outcomes, offering comparable nutritional quality and yield to the 15 and 20 t ha⁻ treatments. Relative to the control, grain yield increased by 54.6%, 94.6%, 93.5%, and 91.4% for 5, 10, 15, and 20 t ha⁻ treatments, respectively. The 10 t ha⁻ application rate was the most cost-effective and beneficial for improving soil properties and maize productivity, as indicated by the benefit-to-cost ratio. This study recommended the use of 10 t ha⁻ poultry manure for soil fertility management, sustainable nutrition, and enhanced maize performance in the study area. The findings highlight poultry manure's potential to improve soil properties, maize yield, and nutrient content, contributing to better human nutrition in areas with depleted soils.
尽管养分水平对人类健康至关重要，但关于家禽粪便对土壤特性、矿物质组成和玉米生长性能影响的研究信息却很匮乏。本研究的目的是考察家禽粪便对土壤性质、谷物矿物质含量、玉米生长、谷物产量和经济效益的影响。2022年至2023年，在翁多州阿孔巴-阿科科的阿德昆勒·阿贾辛大学教学研究农场进行了为期两年的田间试验，采用随机完全区组设计，设置五个家禽粪便施用量水平（0、5、10、15和20吨/公顷），重复三次。家禽粪便显著降低了土壤容重，改善了孔隙度、水分含量、化学性质和谷物矿物质组成。随着家禽粪便施用量的增加，玉米生长和产量提高，但10吨/公顷的处理效果最佳，其营养品质和产量与15吨/公顷和20吨/公顷的处理相当。与对照相比，5、10、15和20吨/公顷处理的谷物产量分别提高了54.6%、94.6%、93.5%和91.4%。成本效益比表明，10吨/公顷的施用量在改善土壤性质和玉米生产力方面最具成本效益且有益。本研究建议在研究区域使用10吨/公顷的家禽粪便进行土壤肥力管理、可持续营养供应和提高玉米性能。研究结果突出了家禽粪便在改善土壤性质、玉米产量和养分含量方面的潜力，有助于在土壤贫瘠地区改善人类营养状况。
