Abstract

Climate change, driven by anthropogenic activities, has far-reaching consequences for our planet. Among its many impacts, changes in temperature, elevated carbon dioxide levels, and shifts in greenhouse gas concentrations significantly affect soil ecosystems. In particular, soil microbial communities play a pivotal role in nutrient cycling, organic matter decomposition, and overall soil health. Soil microbial communities respond differently to the effects of climate change, like elevated warming and precipitation. The change in climatic conditions is reported to be adversely affecting soil biological activity directly through either drying or wetting of soil or affecting their associated plants. This review delves into the intricate relationship between climate change and soil microbial abundance, diversity, and distribution. The paper also discusses climatic change pressure on soil enzymatic activity and microbial biomasses, as well as soil faunal activity, as they are key indicators of soil health in a changing climate. Soil microbial communities cope with climate change by changing their diversity and physiological characteristics and by changing their symbiotic plants, which indicates the role of soil microbes in withstanding the negative impact of climate change.

Abstract

Besides its significance in human nutrition and being cash crop in Ethiopia, turmeric is produced far below the countries potential, due to the depletion of major soil nutrients. This crop requires adequate fertilizer application. The purpose of this field experiment was to evaluate the effectiveness of the blended NPSB fertilizer indicated by the Ethiopian soil information system (EthioSIS) soil fertility map for turmeric production in the study area. The treatments were laid out in a randomized complete block design with three replications. The treatments included two controls (control and recommended NP fertilizer) and nine combinations of NPSB fertilizer (100, 150, and 200 kg ha-1) and, N fertilizer (Urea) (150, 200, and 250 kg ha-1) arranged in RCBD with three replications. The showed that the applying increased rate of blended NPSB along with urea did not brought significant improvement) in growth and yields components of turmeric over existing treatment groups compared to negative control. The highest fresh rhizome yield (41.52 t ha-1) was obtained from the application of 100 NPSB with 250 urea. Since the blended fertilizer, non-significantly increased turmeric yield, farmers in the study area and similar agro ecologies could use the previously recommended NP fertilizer for turmeric production.
