“…Sufficient availability of plant nutrients might have played an important role in the synthesis of photosynthetic pigments such as Chl-a, Chl-b, total Chl (a+b), and carotenoids and growth regulating hormones [48]. Our findings are supported by earlier research where plant growth parameters were increased as a result of biochar application [53][54][55][56][57][58][59][60].…”

Biochar is one of the important recycling methods in sustainable development, as it ensures the transformation of agricultural wastes into fertilizers and conditioners that improve soil properties and fertility. In the current study, corn cob-derived biochar (CB) was used to reduce the negative effects of saline water on quinoa (Chenopodium quinoa cv. Utosaya Q37) grown on Aridisols and Entisols, which are the major soil groups of Egyptian soils. Quinoa plants were cultivated in pot experiment and were irrigated with saline water (EC = 10 dS m−1). The experiment contained three treatments, including control without any treatment, biochar at a rate of 1% (w/w) (BC1), and biochar at a rate of 3% (w/w) (BC3). The findings of the current study showed that BC treatments realized significant effects on soil salinity, pH, soil organic matter (SOM), and plant availability and nutrients’ uptake in the two soils types. BC3 increased the SOM in Entisols and Aridisols by 23 and 44%; moreover, the dry biomass of quinoa plants was ameliorated by 81 and 41%, respectively, compared with the control. Addition of biochar to soil increased the nutrients’ use efficiencies by quinoa plants for the two studied Egyptian soils. Biochar addition caused significant increases in the use efficiency of nitrogen (NUF), phosphorus (PUE), and potassium (KUE) by quinoa plants. BC3 increased NUE, PUE, and KUS by 81, 81, and 80% for Entisols, while these increases were 40, 41, and 42% in the case of Aridisols. Based on the obtained results, the application of corn cob biochar improves the soil quality and alleviates the negative effects of saline irrigation on quinoa plants grown on Aridisols and Entisols Egyptian soils. Biochar can be used as a soil amendment in arid and semi-arid regions to reduce the salinity hazards.

“…Biochar is characterized by its higher content of more stable organic carbon compounds compared to compost, and thus it slowly decomposes in the soil 34 , 36 , thus, it becomes more effective in improving the soil physiochemical properties 36 . The decomposing organic materials in compost encourage the growth of soil microorganisms and increase the activity of soil enzymes 43 , 48 . The integrated effect of compost and biochar improves the physicochemical properties of soil and increases the activity of soil enzymes and microorganisms better than the single additives 33 , 34 .…”

Soil amendments may increase the slate tolerance of plants consequently; it may increase the opportunity of using saline water in agricultural production. In the present pot trial, the effects of biochar (BIC) and compost (COM) on roselle (Hibiscus sabdariffa L.) irrigated with saline water (EC = 7.50 dS m−1) was studied. Roselle plants were amended with biochar (BIC1 and BIC2) or compost (COM1 and COM2) at rates of 1 and 2% (w/w), as well as by a mixture of the two amendments (BIC1+). The experiment included a control soil without any amendments. Biochar and compost significantly enhanced the soil quality and nutrients availability under saline irrigation. Compost and biochar improved the degree of soil aggregation, total soil porosity and soil microbial biomass. BIC1 + COM1 increased the soil microbial biomass carbon and nitrogen over the individual application of each amendments and control soil. BIC1 + COM1 increased the activity of dehydrogenase and phosphatase enzymes. Growth of roselle plants including: plant height, shoot fresh and dry weight, and chlorophyll were significantly responded to the added amendments. The maximum sepal’s yield was achieved from the combined application of compost and biochar. All the investigated treatments caused remarkable increases in the total flavonol and anthocyanin. BIC1 + COM1 increased the total anthocyanin and flavonol by 29 and 17% above the control. Despite the notable improvement in soil and roselle quality as a result of the single addition of compost or biochar, there is a clear superiority due to mixing the two amendments. It can be concluded that mixing of biochar and compost is recommended for roselle plants irrigated with saline water.

“…This assumes significance as residue and KSB biofertilizer under zero tillage maize-wheat system supplements inorganic K fertilize. Ali et al [17] studies applying of bio-fertilizer with Bacillus cereus significantly increased the total yield of potato by 21% above the untreated plants. The application of K-feldspar (12% total K 2 O) at a rate of 240 kg K 2 O ha -1 to potato inoculated with Bacillus cereus gave a total tuber yield of 40 ton ha-1 .…”

Two field experiments were conducted in a calcareous soil during summer seasons of 2019 and 2020 at the experimental in a private farm Mallawi, El- Minia Governorate, Egypt to evaluate application of K fertilization at different rates of K2SO4 and non-classic products, i.e. K feldspar, mixture with or without inoculation with the K dissolving bacteria (Bacillus circulans.) soil chemical properties, plant growth, yield and nutritional value of corn (Zea-maize hybrid third 310). Our results proved that inoculation of maize seeds with Bacillus circulans at rate of 36% K2O improved soil pH, EC, soil organic matter content and enhanced the soil available N, P and K concentrations. Also, the growth parameters, yield and nutritional status of the plants were significantly increased by using non-traditional potassium fertilizers particularly in the case of seed inoculated with potassium dissolving bacteria (Bacillus circulans).
