Dyason Tea Tree trial. New South Wales, 2015 [Action on the Ground]

This project trialed an application of industry standard of 5t/Ha of poultry litter (wet), both surface broadcast and cultivated as a nitrogen fertiliser.

The trial also compared N2O emissions from these with cultivated treatments of poultry litter and Tea Tree biochar, poultry litter biochar and Tea Tree biochar and poultry litter and Tea Tree mulch. (The latter 3 treatments equalised for C application.)

本项目针对行业通用标准的5吨/公顷湿禽粪（wet poultry litter）施用量方案开展田间试验，分别采用地表撒施与翻耕入土两种方式将其作为氮肥施用。本次试验还将上述处理的一氧化二氮（N₂O）排放，与以下翻耕施用的处理组进行对比：湿禽粪配施茶树生物炭（Tea Tree biochar）、禽粪生物炭（poultry litter biochar）配施茶树生物炭，以及湿禽粪配施茶树覆盖物（Tea Tree mulch）。（注：后三组处理的碳施用量保持一致。）
