Mitigation strategies for soil acidification based on optimal nitrogen management

● Soil acidification is determined by proton production and soil buffering capacity. ● Cropland acidification is mainly caused by anthropogenic activities. ● Nitrogen transformations dominate anthropogenic soil acidification processes.

Soil acidification effects on nutrient dynamics in paddy rice systems including causes impacts and sustainable management strategies

Discover Sustainability
Soil acidification in paddy rice systems, where soil pH drops below the optimal 5.5–6.5 range, threatens global rice production by impairing root function, nutrient uptake, and microbial activity.

Striking a balance between N sources: Mitigating soil acidification and accumulation of phosphorous and heavy metals from manure

, 2020
Manure amendment has been shown to effectively prevent red soil (Ferralic Cambisol) acidification from chemicalnitrogen (N) fertilization. However, information is lacking on how much manure is needed to mitigate acidificationand maintain soil ...

Does soil acidification affect spruce needle chemical composition and tree growth?

, 2001
In 1994, a large survey of soil chemistry was undertaken in the county of Värmland in central Sweden (Lundström et al., 1998). The southern part of the county was affected by soil acidification whereas there were no such indications in the northern part.

Does Slight Soil Acidification Negatively Affect Diazotrophic Bacterial Community in Paddy Field? A Regional-Scale Study

Ecosystem Health and Sustainability
Diazotrophic bacteria are eco-friendly alternatives for reducing chemical N fertilizer use. Yet, their responses to soil acidification from excessive fertilization in paddy ecosystems remain unclear. To elucidate this issue, we compared the structure and
