“…Biochar and zeolite amendment will also affect the availability of toxins that determine the growth and activity of the microbial community. Zeolite can absorb the NH 4 + cations in water [16], soils [50] and composting piles [51]. At the thermophilic stage, addition of biochar consequently alleviated the initial low pH [35].…”

The effects of zeolite and biochar addition on ammonia-oxidizing bacteria (AOB) and archaea (AOA) communities during agricultural waste composting were determined in this study. Four treatments were conducted as follows: Treatment A as the control with no additive, Treatment B with 5% of zeolite, Treatment C with 5% of biochar, and Treatment D with 5% of zeolite and 5% biochar, respectively. The AOB and AOA amoA gene abundance as well as the ammonia monooxygenase (AMO) activity were estimated by quantitative PCR and enzyme-linked immunosorbent assay, respectively. The relationship between gene abundance and AMO enzyme activity was determined by regression analysis. Results indicated that the AOB was more abundant than that of AOA throughout the composting process. Addition of biochar and its integrated application with zeolite promoted the AOB community abundance and AMO enzyme activity. Significant positive relationships were obtained between AMO enzyme activity and AOB community abundance (r2 = 0.792; P < 0.01) and AOA community abundance (r2 = 0.772; P < 0.01), indicating that both bacteria and archaea played significant roles in microbial ammonia oxidation during composting. Using biochar and zeolite might promote the nitrification activity by altering the sample properties during agricultural waste composting.

One of the most important problems of agriculture is finding new methods to increase soil fertility and productivity. The use of fertilizers increases the efficiency of nutrients, however, their uncontrolled use leads to leaching and contamination of the environment. Zeolite is considered a natural element that has no negative environmental effects. Its ion exchange properties are important for plant nutrition due to its cation exchange ability and porosity. Zeolites added to fertilizers give a double result when applied to soil: provide long lasting action of fertilizer (prolongation effect) and prevent nutrient leaching. This article analyzes current literary sources of information on the use of zeolite-based composites as a prolonged action fertilizer in agriculture, as well as their impact on nutrient retention and release into the soil.

“…The process of activation and modification of fly ash can activate nutrients or improve water retention capacity, to reduce its application amount. Additionally, lots of studies have shown that the application of fly ash-based soil conditioner will not enhance the accumulation of heavy metals (HMs) in various plant tissues, and the application of fly ash-based soil conditioner in a safe ratio (less than 8%) is beneficial to plant growth and development [15,16]. However, these studies are limited to laboratory research, and the risk of CFA heavy metals contamination and large-scale field trials are rarely reported.…”

The utilization of coal fly ash (CFA) as a soil conditioner has been a research hotspot in recent years. In this paper, the continuity and stability of the yield-increasing effect of a fly ash-based soil conditioner were investigated through field trials for three consecutive years. The yield-increasing effect and applicability were also investigated by planting a variety of crops in different types of soil. Field test results revealed that the new fly ash-based soil conditioner had wide adaptability and stability under the condition of reducing the application of traditional fertilizers by 20%. For corns grown in castano-cinnamon soil and dark brown soil, the application of the new fly ash-based soil conditioner for three consecutive years has steadily increased the yield by more than 10%. The yield of wheat planted in castano-cinnamon soil also increased by 15%. Additionally, considering that heavy metals (HMs) contained in the fly ash-based soil conditioner may cause environmental contamination, this paper calculated and analyzed the bio-concentration factor (BCF) and the translocation factor (TF) of Cr, As, Cd, Hg and Pb in the corn experimental fields. The results showed that the five heavy metals were not significantly enriched in various parts of the corn stalk after application of the soil conditioner, and there was temporarily no environmental risk in terms of returning straws to the field or raising livestock.
