Abstract
This study investigated the effects of solid oxygen fertilizers (SOFs) and biochars on nitrous oxide (N₂O) production in Florida agricultural soils. Organic soil showed higher N₂O production than mineral soil, significantly increased by nitrogen fertilizer. SOFs reduced N₂O production in mineral soil (98-99%) and calcium peroxide in organic soil (25%). Biochar effects varied depending on soil type and biochar source. SOFs maintained higher nitrate-N levels. The study suggests SOFs as a potential strategy for reducing N₂O emissions from flooded agricultural soils.
