Soil acidification associated with changes in inorganic forms of N reduces the yield of tea (Camellia sinensis)

Archives of Agronomy and Soil Science, 2022
In this study, 145 tea soils were analyzed and exploredthe relationship between soil pH and soil nitrogen forms and tea yield, which is helpful for more accurate fertilization management, so as to improve tea yield and restore acidified soil. The results

Reducing aluminum is the key nutrient management strategy for ameliorating soil acidification and improving root growth in an acidic citrus orchard

Land Degradation & Development, 2022
Aluminum (Al) toxicity is one of the most serious hazards of soil acidification, which limits root formation and hinders crop growth. Soil acidification in orchards has been widely reported.

Dramatic loss of inorganic carbon by nitrogen‐induced soil acidification in Chinese croplands

Global Change Biology, 2020
Intensive crop production systems worldwide, particularly in China, rely heavily on nitrogen (N) fertilization, but left more than 50% of fertilizer N in the environment.

Differential soil acidification caused by parent materials and land‐use changes in the Pearl River Delta region

Soil use and management, 2022
Soil acidification occurs widely across the world, which has been partly attributed to land‐use change. However, measureable effect of land‐use change as well as parent materials on soil acidification remains poorly understood.

Soil Acidification/N Cycling

1991
Publisher Summary In the Dutch Priority Programme on Acidification, soil acidification and related processes have been studied at various sites in forests and heathlands, mostly in association with related research dealing with atmospheric deposition and with various affects of acid deposition on biota.

Proton Sinks in Soil Controlling Soil Acidification

1991
This presentation concerns the reaction of the soil and its various constituents with added protons and the ensuing changes induced in the systems’s properties. As these properties largely manifest themselves via the “carrier” agent, the soil solution, it seems logical to use the proton activity in the soil solution, or soil pH value, as the principal ...

Acidification and alkalinization of soils

Plant and Soil, 1983
Acidification or alkalinization of soils occurs through H+ transfer processes involving vegetation, soil solution and soil minerals. A permanent change in the acid neutralizing capacity of the inorganic soil fraction (ANC(s)),i.e. soil acidification (ΔANC 0), results from an irreversible H+ flux. This irreversible H+ flux can be caused either by direct

Soil Acidification: Fundamental Concepts

1986
Natural soil acidification processes have been recognized and studied for decades or perhaps centuries. An understanding of these processes is essential to an understanding of soils and of natural and agricultural ecosystems. One of the most important characteristics of soils is the cation-exchange complex.

Soil Acidification and Alkalinization

1991
In this chapter I briefly discuss the nature of soil acidification and alkalinization, and define these processes in terms of changes in the relevant capacity factors. Next, the contribution of various sources of soil acidification and their quantitative importance is treated in some detail: (1) effects of addition of acids or bases by irrigation and ...
