Enriched Linz-Donawitz (LD) slag application for improving grain yield and quality of wheat grown under nutritionally poor degraded soil. Journal of Environmental Biology. 2024 Dec; 45(6): 666-6750254-87042394-0379https://imsear.searo.who.int/handle/123456789/247541Aim: To evaluate the impact of enriched steel slag on the physico-chemical characteristics of soil and yield attributes of wheat under poor quality degraded soil. Methodology: Steel slag was biologically and organically amended with natural sources of phosphorus (P), sulfur (S), potassium (K) and nitrogen (N) and characterized for its nutrient content along with biological activity. The impact of resultant products was assessed on soil quality and yield component traits of wheat for two consecutive years(2021-2022 and 2022-23). Results: Application of slag based products significantly (p<0.05) improved the plant height, biological yield, grain yield and ear bearing tillers (EBT) of -1 wheat even with 80% of recommended fertilizer dose (NPK). Further, in comparison to control, a moderation of soil pH (8.6 to 8.8), EC (0.18 to 0.20 dS m ), -1 -1 -1 OC (0.22 to 0.24 %) and essential mineral macronutrients viz., N (126 to 130 kg N ha ), P (8.0 to 13.0 kg ha ), K (100 to 125 kg ha ) were observed with the application of amended steel slag products. No significant change with respect to existing heavy metal concentration viz., Co, Ni, Cd and Pb in soil was observed when supplemented with amended slag products. Interpretation: Steel slag can be transformed favorably for on-farm application to improve wheat yield besides serving as an environmentally sustainable alternate of soil conditioner for the management of degraded soil.Degraded soilHeavy metalsSteel slagWaste managementWheatEnriched Linz-Donawitz (LD) slag application for improving grain yield and quality of wheat grown under nutritionally poor degraded soilJournal ArticleIndiaNutri-Cereals Research Station, Chaudhary Charan Singh Haryana Agricultural University, Hisar-125 004, IndiaDepartment of Botany and Plant Physiology, College of Basic Sciences and Humanities, CCS Haryana Agricultural University, Hisar-125 004, IndiaCollege of Basic Sciences and Humanities, Chaudhary Charan Singh Haryana Agricultural University, Hisar-125 004, IndiaDivision of Environment Science, Indian Agricultural Research Institute, New Delhi-110 012, IndiaDivision of Environment Science, Indian Agricultural Research Institute, New Delhi-110 012, IndiaDivision of Environment Science, Indian Agricultural Research Institute, New Delhi-110 012, IndiaDivision of Environment Science, Indian Agricultural Research Institute, New Delhi-110 012, IndiaDivision of Environment Science, Indian Agricultural Research Institute, New Delhi-110 012, India
