“…The application of biochar (pyrolysis d at 600°C) to soil was improves soil organic carbon and soil pH and would have an effects on soil enzymes, microbial biomass for soil quality. It was found that soil pH, total organic carbon and urease increased significantly with increasing biochar rate (Walelign and Mingkui 2015).…”

This experiment was carried out in sandy loam soil of private farm at Romana , North Sinai Governorate, Egypt during two successive winter seasons 2017 / 2018 and 2018 /2019, to study the effect of three types of biochar, (A) produced from corn stalk, straw rice , straw of faba bean and cotton stalk, (B) produced from trees stalk and (C) town refuse, with three levels from Urea fertilizer (0, 20, 30 Kg N/fed), plus control treatment which received the recommended dose of urea (46 %N), to examine the effects of biochar types combined with or without nitrogen fertilizer on faba bean productivity under saline soil conditions. Faba bean variety Giza 843 were sowed on 12 November 2017 and 2018.The experiment was carried out in a split plot design with three replicates. Results obtained that, the combination between biochar types with different levels of N fertilizer enhanced all tested parameters. Moreover, biochar type (C) with level 30 Kg N/fed recorded the highest values of all tested parameters. On the other hand, the same treatment was the most effective on the root rot and wilt incidences, where the survival plants was 97.9 % and 93.4% respectively and decreased the number of the pathogenic fungi.

“…Spearman's correlation coefficients between the selective soil chemical and biological properties (n=3) Table 1. study of Demisie and Zhang (2015), the application of oak wood biochar and bamboo biochar at the same doses (1 and 2%) did not significantly increase the phosphatase activity. However, these authors found significantly higher values of phosphatase activity in the analysed soils (from 115 to 149 µg pNP g -1 DM h -1 ).…”

Soil microorganisms play a key role in many biochemical processes essential for the environment and for the ecological and production functions of soils, hence they are very important quality indicators. The study aimed at evaluating the effect of 1 and 2% additions of wheat and miscanthus straw biochars on soil enzymatic activity (dehydrogenases, urease, phosphatases) and the number of microorganisms (bacteria, fungi, actinobacteria). Pot experiments were carried out on soil with a loamy sand texture. The geometric mean of enzyme activities, biological index of fertility, and the integrated total enzyme activity index were used to explore the relationships between soil enzyme activities and the microbiological and chemical properties of soil. The addition of 1% miscanthus straw biochar had the most beneficial effect on the number of bacteria and fungi (increase by 380 and 26%, respectively), and 1% wheat straw biochar on the number of actinomycetes (increase by 273%). The correlation analysis between the number of actinomycetes and the chemical parameters of the soil showed the significant effect of the content of N total (r = 0.76) and C total (r = 0.85). The values of biological index of fertility, total enzyme activity index and geometric mean of enzyme activities indexes showed that the best quality of soil was produced by a 2% addition of wheat straw biochar.

“…It was observed that the amendment of GAS residues significantly elevated soil N (including TN, NH 4 -N and NO 3 -N) content and pH, while significantly decreased AP content especially at high amendment levels. The input of N would increase the activity of ACP, while the elevation of soil pH would substantially decrease the activity of ACP 74,75 . These results probably indicate that there is a threshold of soil pH, which determines the activity of ACP influenced by addition of N and elevation of soil pH.…”

It has been shown that the golden apple snail (GAS, Pomacea canaliculata), which is a serious agricultural pest in Southeast Asia, can provide a soil amendment for the reversal of soil acidification and degradation. However, the impact of GAS residue (i.e., crushed, whole GAS) on soil bacterial diversity and community structure remains largely unknown. Here, a greenhouse pot experiment was conducted and 16S rRNA gene sequencing was used to measure bacterial abundance and community structure in soils amended with GAS residue and lime. The results suggest that adding GAS residue resulted in a significant variation in soil pH and nutrients (all P < 0.05), and resulted in a slightly alkaline (pH = 7.28–7.75) and nutrient-enriched soil, with amendment of 2.5–100 g kg−1 GAS residue. Soil nutrients (i.e., NO3-N and TN) and TOC contents were increased (by 132–912%), and some soil exocellular enzyme activities were enhanced (by 2–98%) in GAS residue amended soil, with amendment of 1.0–100 g kg−1 GAS residue. Bacterial OTU richness was 19% greater at the 2.5 g kg−1 GAS residue treatment than the control, while it was 40% and 53% lower at 100 g kg−1 of GAS residue and 50 g kg−1 of lime amended soils, respectively. Firmicutes (15–35%) was the most abundant phylum while Bacterioidetes (1–6%) was the lowest abundant one in GAS residue amended soils. RDA results suggest that the contents of soil nutrients (i.e., NO3-N and TN) and soil TOC explained much more of the variations of bacterial community than pH in GAS residue amended soil. Overuse of GAS residue would induce an anaerobic soil environment and reduce bacterial OTU richness. Soil nutrients and TOC rather than pH might be the main factors that are responsible for the changes of bacterial OTU richness and bacterial community structure in GAS residue amended soil.
