“…Moreover, the rapid increase in moisture content could stimulate growth and metabolisms of some microorganisms. In addition, P. polymyxa could also hold the capability of metabolizing and degrading organic matters in the composting piles, which was consistent with the traditional process of producing bio-organic fertilizer [3,9]. The value of EC and GI were also an important parameters in determining the compost stability and maturity [35].…”

“…Moreover, the chemical pesticides used have negative effects on some beneficial microbes that facilitate soil nutrient recycle and nutrient uptake by plant roots [2]. With the increasing concern to food safety and environment changes, biological control methods have become increasingly used as an alternative to chemical pesticides and been considered as a promising strategy for plant disease management [3]. Bio-organic fertilizer has become one of the main methods of biological control due to its special function of disease-resistant strains [4,5], which is main coming from composting technology.…”

“…Bio-organic fertilizer has obvious advantages for environment as well as for health of human beings. Many researchers have studied and developed methods of producing bio-organic fertilizer in their related fields [3,9]. One of the traditional or widely used methods of producing bio-organic fertilizer [10] is the composting process containing two consecutive stages (TCS) of composting fermentation.…”

The traditional method of producing bio-organic fertilizer contains two consecutive composting stages which, however, is time-consuming and requires high input of energy and cost. This study attempted to combine two consecutive stages into one single step. Paenibacillus polymyxa, as an antagonistic strain to control anthracnose in Chinese Pakchoi, was used as inoculum to obtain bio-organic fertilizers through two approaches: two consecutive stages (TCS) composting as control and the proposed one step through (OST) composting. The resulting two bio-organic fertilizers produced by TCS and OST were tested for the disease incidence and disease resistant index, and the fertility on growth of Chinese Pakchoi. The results of relative abundance of P. polymyxa showed no significant difference between two kinds of bio-organic fertilizers in phylum, family and genus. The disease incidence of bio-organic fertilizers produced by OST and TCS reduced by 61.40% and 68.42%, respectively, as compared to the control group, where the difference was not significant. The growth promoting effect was remarkable, although the difference in the fertility on the growth was not significant. Compared with the traditional TCS method, the novel OST method could improve efficiency of bio-organic fertilizer production by 42.86% per year according to this study.

“…Properties of biochar such carbonaceous materials, degree of aromatization, elemental composition, pH, pore structure, surface chemistry, etc., plays vital roles in its ability to adsorb organic pollutants [41]. Biochar therefore reduces CO 2 emissions into the atmosphere [39].…”

Conversion of agricultural wastes into eco-friendly and low cost biochar is not only a smart recycling strategy but a panacea to environmental pollution management. Agricultural wastes biochar can be an effective alternative technique for controlling contaminants due to its low cost, high-efficiency, simple to use, ecological sustainability and reliability in terms of public safety. Biochars have made substantial breakthroughs in reducing greenhouse gases emissions, reducing soil nutrient leaching, sequester atmospheric carbon into the soil, increasing agricultural productivity, and reducing bioavailability of environmental contaminants. Recent advances in the understanding of biochars warrant a proper scientific evaluation of the relationship between its properties and impact on soil properties, environmental pollutant remediation, plant growth, yield, and resistance to biotic and abiotic stresses. The main factors controlling biochar properties include the nature of feedstock, heat transfer rate, residence time and pyrolysis temperature. Biochar efficacy in pollutants management largely depends on its elemental composition, ion-exchange capacity, pore size distribution and surface area, which vary with the nature of feedstock, preparation conditions and procedures. The chapter explored the possibility of using biochar from agricultural wastes as a suitable alternative for the remediation of environmental pollutants, soil conditioning and the long-term biochar application in the environment.

“…Studies on bio-organic fertilizer have largely focused on the prevention and control of soil-borne diseases [17], relief from continuous cropping [18], the composition of soil microbial communities and their functional diversity [19,20], and aboveground biomass and yield [21]. There has been a lack of attention on the effect of bio-organic fertilizer on RSA.…”

Background: Root system architecture (RSA) is highly plastic, responding to nutrient availability and the heterogeneity of the soil environment. However, the linkage of root morphology to anatomy and root nutrient, and its implication for root function at the heterogeneous application of bio-organic and chemical fertilizer have not yet been defined, especially for pear trees.Results: In this study, a split-root experiment was conducted using 1-year old ‘Cuiguan’ trees. No fertilizer (NF), chemical fertilizer (CF), and bio-organic fertilizer (BIO) were paired to test six combinations: NF-NF, NF-CF, NF-BIO, CF-CF, BIO-BIO, and BIO-CF. Root morphological, anatomical traits and root nutrient concentrations, and their relationships were determined. Trees receiving BIO had significantly higher lateral root numbers, activity, total lateral root length, and specific root length than trees receiving no BIO, while the effects on root tissue density were the direct opposite. Compared with CF-CF treatment, root xylem thickness, stele diameter, vessel diameter, and number of vessels all increased in response to BIO-CF treatment. Root growth was synergistically promoted in BIO-CF, with increased special root length and root nitrogen concentration, but root tissue density and the carbon:nitrogen ratio were reduced. Intriguingly, the synergistic effect resulted in greater trunk girth without sacrificing height, compared to trees receiving CF or BIO alone.Conclusions: The combination of BIO and CF improves root traits and tree growth, suggesting that using bio-organic fertilizer as a supplement to reduce the application rate of chemical fertilizer is beneficial to orchard ecosystems.
