“…This means that there is high rate of negative changes on organic matter in flooded soils. This finding agreed with that of Medeiros et al (2018) that observed that flooding affects the exchangeable acidity of soil due to its intensity. Also, studies by Shamshuddin et al (2016) and Azuhan (2015) reported that there were significant higher values of TEA in most sampled floodplains.…”

Floods are among the most devastating natural disasters in the world, claiming more lives and causing more property damages than any other natural phenomena. In recent times, the incidence of flooding across Nigeria has left both the government and the governed devastated. It is no longer news that flooding and its attendant consequences are injurious to man while the spatial dimensions are often not mapped. This study, therefore, Analysis of Physical and Chemical Properties of Soils in flooded and Upland Forest areas of Yola-North. Flood analysis for low, medium and high flow regimes showed that physical and chemical properties of soils are being affected. Longitudinal and cross section profiles depict the trend in which sediment loads are transported by flood and presence of boulders along the Benue channel. Sustainable measures such as review of Federal Environmental Protection Agency (FEPA) 1999 flood combat measures, dredging of the Benue and relocation of people living near river banks were suggested for the management of flooding in Adamawa State

“…Clay content increases with the reduction of sand content. Medeiros et al (2018) report that electrical conductivity (EC) demonstrates a positive correlation with soil water content, while Uddin et al (2021) found that total N increases alongside rising water content. High clay content is well known to cause and influences root growth patterns (Bonomelli et al 2019).…”

Abstract. Yunanto T, Amanah F, Wulansari AR, Wisnu NP. 2021. Effect of soil properties on plant growth and diversity at various ages of coal mine reclamation in Indonesia. Biodiversitas 23: 459-468. Soil is an essential element for plants to grow. Therefore, it is important to understand the influence of soil properties, especially physical and chemical, on plant growth in coal mine reclamation areas. This study aimed to evaluate the growth and diversity of plants at various ages of reclamation and analyze the factors that most influence their growth and diversity. The study analyzed four soil physical properties and eight soil chemical properties. The research was conducted in mine reclamation areas with different ages: 1, 4, 6, 9, and 11-year-old-plantations for vegetation analysis and soil collection. Principal Component Analysis (PCA) analysis was performed using PAST 4.0 statistics program to analyze the data. The results showed that the 9-year-old plantation had the highest mean Shannon Wiener Index (H’= 1.52), mean basal area (35.04 m2/ha), and mean density (469 trees/ha), while the 4-year-old plantation had the highest mean diameter (28.42 cm). The 1-year-old plantation had the highest clay content of 56.28% and the lowest pH of 3.27. The physical properties of the soil affected the growth rate and diversity of the reclamation area more than the chemical properties of the soil. This can be seen from the cumulative proportion of the two PCA values that described the original condition of 71.20% for soil physical properties and 63.10% for soil chemical properties. Based on this study, bulk density affected the diversity while pH impacted other soil chemical properties.

“…In addition, EC is an integral factor in soil fertility for agricultural crops. Studies' reports indicate that extractable amounts of Na and Mg obviously affect the EC [26], as does as the soil texture [27]. The decreasing EC trend may be the cause of increasing relative humidity or the integrated intention of acidification of these three soil treatments.…”

Long-Term Effects of Fertilizers with Regional Climate Variability on Yield Trends of Sweet Corn

Climate change affects global crop production year after year. Exploring the impact of different fertilization methods on crop yield stability has become an extremely important topic in sustainable agriculture. The objective of this study is to explore the effects of various fertilization regimes with climate variability on yield stability for sweet corn production in southern Taiwan. Three fertilization treatments composed of chemical fertilizer only (CF), integrated fertilizer (half organic/half chemical fertilizer) (IF), and organic fertilizer only (OF) were implemented from 2009 to 2018 based on the well-maintained soils since 1988. While the same amounts of these fertilizers were applied during the period, we found that different fertilization changed the marketable yields of fresh fruit (ear), which slightly increased for organic fertilizer, but substantially decreased for both chemical (p = 0.0001) and integrated (p = 0.0061) fertilizer. Thus, based on these 10 years of observation, yields among fertilization treatments were analyzed with weather and soil parameters to determine the possible factors involved. Both multiple linear regression equation (p < 0.0001, adj. R2 > 0.57) and regression tree analysis illustrated significantly negative correlations between average ear weight and relative humidity under the chemical fertilizer treatment. In this study, we show for the first time that chemical fertilizer had the lowest yield resilience in response to regional relative humidity change compared to organic and integrated fertilizers. Our results also indicate that specific soil microbes have the potential to help sweet corn face environmental vulnerability in subtropical regions.
