“…Microbes in the soil play an important role in soil redox chemistry, as they can consume or produce electron donors and acceptors. The first report to show that lightning has effects on soil properties, organic matter availability and microecology, and plant growth has been published very recently [10]. Also, very recent results show that lightning can cause phosphorous reduction [11] and other redox changes [12,13] in soils.…”

Atmospheric electric fields (AEFs) have recently been proposed to link to biogeochemical processes below the Earth’s surface by means of a charge separation. Despite the potential importance of such a process, up to now we almost completely lack the relevant measurements. Here, we extend the database with 2 months of concurrent soil redox and atmospheric electric field measurements. It appears that the changes that occur in the order of days in soil redox are at periods anticorrelated with the logarithm of the positive values of the AEF. However, weather conditions might be driving the anticorrelation rather than a direct link, as the synoptic weather conditions appear to influence soil redox. Soil redox does not respond to changes in the AEF that are of shorter duration, either minutes or several hours, except in some cases of very negative AEFs or very high field strengths in the presence of moderate rainfall. In such a case, the variation in soil redox could be associated with a mechanism that transfers charge to the ground or brings ions towards the ground’s surface. To reach firmer conclusions on the effect of the AEF on soil redox, we need to extend the range of collocated soil redox and AEF measurements so that they cover at least one year.

Tea (Camellia sinensis L.), an important economic crop in China, is highly favored by the population. Microorganisms can help plants acquire soil nutrients and cope with various stresses, and the diversity and structural composition of the rhizosphere microbial community of tea plants are crucial for ensuring the growth and quality of tea leaves. Therefore, we studied the differences in soil nutrients, enzyme activities and microbial communities between two different tea gardens (a tableland tea garden and an ancient tea plantation) in different ecological niches (rhizosphere and bulk soil), as well as the impacts they experienced. The results show that the soil pH levels in the ancient tea plantation were within the optimal range (4.5–5.5), and both rhizosphere and bulk soil nutrients in the ancient tea plantation were higher than those in the tableland tea garden, except for TP; the nutrients in the rhizospheres of ancient tea trees were more abundant. Moreover, higher enzyme activities were observed in the rhizosphere soil than those in the bulk soil in both tea gardens, and both the tableland and ancient tea garden soils were subjected to a certain degree of C&N limitations. The microbial communities of the two tea gardens were dominated by bacteria, but the α-diversity of the bacterial and fungal communities in the rhizosphere soil of the tableland tea garden was higher than that in the ancient tea plantation. The bacterial communities were largely dominated by Proteobacteria and Acidobacteriota, and the fungal communities were largely dominated by Ascomycota and Basidiomycota in the two tea gardens. The structure and composition of soil bacterial communities in the two tea gardens were similar, whereas significant differences were observed in the fungal communities. In addition, soil pH and SWC were the key factors influencing the fungal community in both the rhizosphere and bulk soil in the two tea gardens, whereas the bacterial community was more significantly affected by soil TN, NH4+-N, SWC and DON. These findings provide essential foundational information for the preservation of ancient tea plantations, the ecological adaptability of ancient tea trees and the management of tableland tea gardens.

A Review on Lightning and its effects on Trees

Lightning in mother’s nature show, which cannot be controlled. Lightning contacts the earth about more than 8 million times a day. Due to so many strikes, the probability of damage to the plants and trees is very high. The total available energy for an average lightning stroke is of the order of 108 Joule. Of the total available energy about 85-90% is dissipated in resistive part of the air column, which appears as heat energy to raise the temperature of column so high, that shock waves are produced due to expansion of the column and strong thunder is produced utilizing almost whole of this heat energy. These heat and shock waves generated during lightning process can damage or even kill the trees instantaneously. Lightning may cause wilting, yellowing, premature fruit drop and other severe injuries to trees. Also, the probability of a tree being struck by lightning depends on the tree size and morphology. This paper seeks to present a review on lightning phenomena, its effects on trees and also provides a brief information how difference among trees can influence lightning effect.
