“…The supernatant, containing actinobacteria was diluted and placed on agar media [21]. glycerol-yeast extract agar (glycerol 5 mL, yeast extract 2 g, K 2 HPO 4 1 g, agar 15 g, distilled water 1000 mL) containing nystatin (50 µg/mL) was used as the isolation medium [22]. The isolation plates were incubated at 28 • C for 14 days.…”

“…Ten grams of each soil sample was added to 95 mL of 0.1% (w/v) solution of sodium pyrophosphate. After homogenization for 30 min, this solution was decimally diluted (10 −1 to 10 −7 ) and aliquots of the resulting solutions plated on appropriate culture media included tryptone soy agar for total microbial count, MacConkey agar for coliform counts, glycerol-yeast extract agar for actinomycetes counts, and Czapek Dox agar for fungi counts [22]. After incubation at 25 or 30 • C for up to10 days, the colony-forming units (CFU) were counted.…”

The use of actinomycetes for improving soil fertility and plant production is an attractive strategy for developing sustainable agricultural systems due to their effectiveness, eco-friendliness, and low production cost. Out of 17 species isolated from the soil rhizosphere of legume crops, 4 bioactive isolates were selected and their impact on 5 legumes: soybean, kidney bean, chickpea, lentil, and pea were evaluated. According to the morphological and molecular identification, these isolates belong to the genus Streptomyces. Here, we showed that these isolates increased soil nutrients and organic matter content and improved soil microbial populations. At the plant level, soil enrichment with actinomycetes increased photosynthetic reactions and eventually increased legume yield. Actinomycetes also increased nitrogen availability in soil and legume tissue and seeds, which induced the activity of key nitrogen metabolizing enzymes, e.g., glutamine synthetase, glutamate synthase, and nitrate reductase. In addition to increased nitrogen-containing amino acids levels, we also report high sugar, organic acids, and fatty acids as well as antioxidant phenolics, mineral, and vitamins levels in actinomycete treated legume seeds, which in turn improved their seed quality. Overall, this study shed the light on the impact of actinomycetes on enhancing the quality and productivity of legume crops by boosting the bioactive primary and secondary metabolites. Moreover, our findings emphasize the positive role of actinomycetes in improving the soil by enriching its microbial population. Therefore, our data reinforce the usage of actinomycetes as biofertilizers to provide sustainable food production and achieve biosafety.

“…The sustainable management can play an important role in addressing the issue of soil fertility. In recent years, there has been an increasing interest in the challenge's problems of soil fertility all over the world (e.g., El-Naggar et al 2019;Hozzein et al 2019). These problems may impact on the crop production in the coastal sandy soils in Egypt including waterlogged soils, polluted soils, saltaffected soils, and alkaline soils (pH more than 8, then several micronutrients will be not available).…”

S TRESSED environments have long been a question of great interest in a wide range of fields. So, many considerable literatures have grown up around this theme. In Egypt, there are several common problems related to the stressed environments. These stresses include decline of soil fertility, soil salinity and alkalinity, soil water logging, salt-affected soils, soil pollution, climate change, overpopulation growth, urban sprawl, land degradation, deterioration of natural resources, etc. More generally, national income will decline and will in turn result in the spread of social and political problems. Kafr El-Sheikh governorate can be considered one of the most important areas in Egypt, which calls "the governorate of the hope and the future" due to its location and wealths. Whereas, this governorate suffers from the most common stresses in Egypt including pollution, salinity, alkalinity and waterlogging. Great problems have been recorded in Kafr El-Sheikh related to stressed environments and suggested solutions also have been addressed. Therefore, a sustainable management should be adapted for overcoming these stressed environments in Kafr El-Sheikh.

“…A point to note is that the major water sources in the Kingdom of Saudi Arabia are groundwater and desalination of seawater [21]. Therefore, intensive studies are performed to overcome the infertility problems of arid soils in the Kingdom of Saudi Arabia by using organic and inorganic soil amendments, i.e., compost bio inoculums and mineral polymers [22][23][24]. However, these amendments need to be applied intensively because of their low nutritive contents and fast degradation rates [25].…”

Applications of Biochar for Environmental Safety

View full text Add to dashboard Cite

Biochar is a carbon-rich material produced from the pyrolysis of organic biomasses in the absence of oxygen or under low-oxygen conditions. Biochar has received a great interest during the last few decades due to its beneficial roles for carbon dioxide capturing and soil fertility improvement. However, applications of biochar in arid soils are very limited, and there is a lack of knowledge on practical aspects of adding biochar to arid soils. In this chapter, we will focus on biochar applications in the Kingdom of Saudi Arabia soils as an example of arid soils. These soils are characterized by several marks, i.e., high soil pH, sand structures, high CaCO 3 contents, and low soil fertility. In addition, the unsuccessful recycling practices of agricultural and food wastes in the Kingdom of Saudi Arabia are also discussed. This chapter provides an overview of current biochar knowledge pertinent to its application to arid soils, summarizes what is known so far about biochar and its applications in arid regions, and demonstrates the possible strategies that can be used for enhancing the practices of biochar addition to these soils.
