Biochar-enriched poultry litter improves soil properties and maize yield

Popis výsledku v původním jazyce

An abstract entitled “Biochar-enriched poultry litter improves soil properties and maize yield” was published in the Book of Abstracts of the XIV International Scientific Agriculture Symposium AgroSym 2023 held on between the 8th to 10th October 2023 in Jahorina (BiH) on page 449. Converting poultry litter into fertilizer is an environmentally friendly way of its disposal. Broiler chicken litter amended with a stabilizing sorption material, such as biochar, may show lower nutrient losses from produced litter and improved fertilizing efficacy. Organic fertilizers produced from biochar-amended chicken litter were used for pot experiment with maize (Zea mays L.) under controlled growth conditions. The properties of three types of matured poultry litter, amended with agricultural waste-derived biochar at dose 0%, 10% and 20%, were analysed. Pot soil amended with matured litters was seeded with maize, cultivated for 12 weeks. Then, physicochemical and biological properties of soil, and dry aboveground crop biomass yield were determined. Increased dry matter and organic carbon content of both biochar-amended matured litters was found compared to unamended litter. Both biochar-amended fertilizers significantly increased dry plant aboveground biomass yield and N-acetyl--D-glucosaminidase activity. The fertilizer with 20% of biochar derived the highest dry plant aboveground biomass, highest respiration induced by D-glucose and D-mannose compared to control litter-treated variant, as well as decreased pH. Modification of the poultry litter maturation process by biochar led to organic fertilizer which enhanced decomposition of soil organic matter in the amended soil. Compared to conventional unamended litter-based fertilizer, this type of organic amendment increased microbial activity, nutrient availability, and biomass yield of maize at selected biochar doses, even under conditions of significant soil acidification.
