Controls and Adaptive Management of Nitrification in Agricultural Soils

Frontiers in Microbiology, Journal Year: 2019, Volume and Issue: 10

Published: Aug. 30, 2019

Agriculture is responsible for over half of the input reactive nitrogen (N) to terrestrial systems; however improving N availability remains primary management technique increase crop yields in most regions. In majority agricultural soils, ammonium rapidly converted nitrate by nitrification, which increases mobility through soil matrix, strongly influencing retention system. Decreasing nitrification desirable decrease losses and fertilizer use efficiency. We review controlling factors on rate extent soils from temperate regions including substrate supply, environmental conditions, abundance diversity nitrifiers plant microbial interactions with nitrifiers. Approaches include those that control inhibit directly. Strategies timing fertilization coincide rapid update, formulation fertilizers slow release or inhibitors, keeping growing continuously assimilate N, increasing assimilation (immobilization). Another effective strategy directly either synthetic biological inhibitors. Commercial inhibitors are but their complicated a changing climate organic requirements. The nitrifying organisms plants microbes producing promising approach just beginning be critically examined. Climate smart agriculture will need carefully consider optimized seasonal these strategies remain tools.

Preventing degradation, facilitating restoration, and maintaining soil health is fundamental for achieving ecosystem stability resilience. A healthy supported by favorable components in the that promote biological productivity provide services. Bio-indicators of are measurable properties define biotic could potentially be used as a metric determining functionality over wide range ecological conditions. However, it has been challenge to determine effective bio-indicators due its temporal spatial resolutions at levels. The objective this review compile set developing better understanding restoration capabilities. It addresses potential including microbial biomass, respiration, enzymatic activity, molecular gene markers, metabolic substances, community analysis have responsive functions agricultural soils, mine deposited soil, heavy metal contaminated desert radioactive polluted pesticide wetland soils. importance United Nations Sustainable Development Goals was also discussed.
