Kev tshawb fawb teb coj los ntawm University of Western Australia tau pom tias hloov ib feem ntawm cov khoom siv hluavtaws nitrogen nrog cov khoom siv qis qis tuaj yeem txhawb nqa qoob loo thaum txhim kho av zoo thiab kev ua haujlwm zoo. Kev tshawb nrhiav,luam tawmhauvAv Degradation & Development, tshuaj xyuas lub caij ntuj no hom qoob mog-lub caij ntuj sov pob kws rotation tshaj ob xyoos nyob rau hauv sib txawv daim ntawv thov nitrogen thiab cov organic chiv ntxiv.
Cov kws tshawb fawb tau tshaj tawm tias txo cov khoom siv nitrogen chiv txog li 45% thiab qee qhov hloov nws nrog cov khoom siv organic txhim kho cov av zoo, qoob loo tsim tau zoo, nitrogen uptake, thiab cov khoom noj khoom haus tsis muaj nitrous oxide emissions. Txoj kev tshawb nrhiav pom tias cov nqi qis ntawm cov kev hloov pauv ntawm cov organic xa tawm cov txiaj ntsig zoo dua li kev ntxiv ntau dua, txhawb kev siv nitrogen ntau dua thaum tswj kev ua liaj ua teb.
Kadambot Siddique, tus thawj coj ntawm UWA Lub Tsev Haujlwm Saib Xyuas Kev Ua Liaj Ua Teb, tau hais tias txo cov khoom siv hluavtaws los ntawm tsawg dua 45% nrog rau cov organic chiv tuaj yeem "tswj cov khoom tsim tau yam tsis muaj kev tso tawm ntxiv." Qhov kev tshawb pom tuaj raws li kev lag luam chiv ntsib kev tsis sib haum xeeb, nrog kwv yees li 60% ntawm kev lag luam thoob ntiaj teb urea txav los ntawm Strait of Hormuz, ua rau cov khoom siv muaj kev cuam tshuam rau thaj chaw tsis sib haum xeeb thiab cov nqi hloov pauv. Cov kws tshawb fawb tau hais tias kev ua kom zoo tshaj qhov sib npaug ntawm cov organic thiab hluavtaws nitrogen tuaj yeem pab txo qis kev ua liaj ua teb emissions thaum ntxiv dag zog rau kev tiv thaiv kev nce nqi nkag.
