Effects of rainfall and fertilizer types on nitrogen and phosphorus concentrations in surface runoff from subtropical tea fields in Zhejiang, China

Diversity and Metabolic Potential of the Dominant Culturable N<sub>2</sub>-Fixing and P-Solubilising Bacteria from Tea (<i>Camellia sinensis</i> L.) Rhizosphere

“…Over the years, productivity of the plant has been decreasing and one of the reasons for this has been attributed to the continuous use of large quantities of chemicals in tea plantations. Many studies showed that excess amounts of N fertilizer application can cause tea orchard soil acidification [7], water pollution [8], and affect nitrification rates [9], contribute to low N use efficiency and also cause serious environmental pollution [7]. Phosphorus is the second of the main limiting factors to the productivity of tea plants and P utilization efficiency is very low in soil due to its low solubility and mobility.…”

Carbon dynamics and environmental controls of a hilly tea plantation in Southeast China

“…In recent years, tea plantations have expanded continuously in hilly areas of Southeast China, and many forests have been cleared and converted to tea plantations. The dramatic increase in tea plantations and strong plantation management practices (pruning and fertilization) have resulted in a series of environmental issues, such as acidification of the soil (Guo et al, ; Li et al, ; Yang et al, ), nitrate leaching into the surrounding water systems (Liu, Yang, Yang, & Zou, ; Xu et al, ), and high rates of N 2 O emissions to the atmosphere (Chen et al, ; Fu et al, , ; Yao, Wei, Liu, Zheng, & Xie, ). This land use change may also affect regional carbon budgets (Ingrisch et al, ; Thom, Rammer, Garstenauer, & Seidl, ), yet the understanding of the carbon dynamics in tea plantation is still poor (Chiti, Diaz‐Pines, Butterbach‐Bahl, Marzaioli, & Valentini, ; Kamau, Spiertz, & Oenema, ; Li et al, ).…”

The effect of bacteria-based formulations on tea (Camellia sinensis L.) growth, yield, and enzyme activities

“…Therefore, to improve the yield of tea leaves, fertilizer is applied to tea orchards, and its use has increased year after year. Many studies show that excess amounts of chemical fertilizer application can contribute to low N use ef ciency and cause tea orchard soil acidi cation as well as serious water and environmental pollution [Han et al 2008, Hirono et al 2009, Liu et al 2012. Microorganisms are important in agriculture to promote the circulation of plant nutrients and minimize the need for chemical fertilizers.…”
