“…The reduction in EC was attributed to the biochar-induced improvement in soil porosity and hydraulic conductivity that accelerated leaching of salt, the adsorption/retention of salts such as Na on the biochar surfaces, or physical entrapment of salts in fine pores of biochar, that decreased salt concentration in soil solution and biochar-induced reduction in the upward movement of salinewater (biochar cover reduced evaporation) resulting in decreased salt accumulation in surface soils (Hammer et al, 2015). These results are agreement with Luo et al, (2017) who demonstrated that biochar can improve leaching of soluble salts to decrease soil EC.…”

“…Biochar enhances the negative effects of salinity by reducing Na + ions by adsorption, which leads to reduce ESP thus, the decrease in soil pH. Luo et al, (2017) found a decline in the pH of soil influenced by salts, owing to hydrogen ion (H +) released from the ion exchange complex by calcium or magnesium brought by biochar. There is another reason for the pH reduction in amended soil with biochar application could be the increment cation exchange cabacity of biochar that advanced enhance plant uptake of potassium, calcium and magnesium, because of the released hydrogen ion (H + ) from the roots to the equilibrium of the charges.…”

Salt stress is abiotic stress that limits plant growth, crop productivity as well as the main factor contributing to land degradation. This study was conducted to evaluate the ameliorative effect of chicken manure and biochar applications used as soil amendments in alleviating the adverse effects of saline water irrigation on plant attributes and macro nutrients uptake by coriander (Coriandrum sativum) plant grown on a sandy textured soil. The ameliorative effect of soil amendments was also evaluated on the properties of the soil and nutrients availability for the plant. For this purpose, a pot experiment was conducted on coriander plant at The Experimental Farm of the Faculty of Agriculture, Mansoura University, Dakahlia Governorate, Egypt. A split plot design with three replications was used during the spring season of 2016. Treatments were the combination of two types of organic amendments (chicken manure and biochar) and three saline irrigation water treatments, .i.e. non-saline water (control) (S0 = 0.45 dS m -1 ) and saline water (S1= 3.12 dS m -1 , 5% and S2 = 6.25 dS m -1 , 10%) irrigation. Obtained results showed that soil productivity, as indicated by the vegetative growth and physiological aspects (plant height, leaves fresh and dry weight, no. of leaves/plant and total chlorophyll) for coriander plant were adversely and significantly affected by saline water irrigation. Addition of chicken manure and biochar significant increased the vegetative growth and physiological parameters due to their ameliorative effect. It had been observed a significantly increased in plant N, P and K contents and uptake by plant due to the addition of chicken manure and biochar amendments under saline and non-saline water irrigation compared to unamended one. The contents and uptake of N, P and K in coriander leaves decreased significantly as salinity of irrigation water increased from (S0) to (S2). Soil pH and EC values increased significantly in saline water irrigation treatments (S1 and S2) compared to non-saline water (S0). Soil pH and EC values decreased in soil amended with chicken manure and biochar application under three water types. The reduction in EC values in soil amended with biochar was higher than those in soil amended with chicken manure under all salinity levels. While, the reduction in soil pH values in soil amended with chicken manure was higher than those in soil amended with biochar. Soil available Na + , K + , Ca 2+ and Mg 2+ concentrations increased with increases in irrigation water salinity, while available P and Zn concentrations were decreased. Soluble Na + significantly decreased but K + , Ca 2+ and Mg 2+ increased as a result of amendments application under three water types used. Soil P and Zn availability increased after applying different soil amendments, the concentration of available P in chicken manure amended soil was higher than those in biochar amended soil. While, available Zn concentration in biochar amended soil was higher than unamended one. In conclusion, chicken manure and bioch...

“…Total nitrogen (TN) was determined with an automatic azotometer (KDN-102F, Qianjian Ltd, Shanghai, China), and NH 4 + -N and NO 3 − -N were measured by spectrophotometric methods with phenol disulphonic acid and indophenol blue reagent, respectively. The soil organic matter (SOM) content was measured by the potassium dichromate-volumetric method (Luo et al, 2016a). The cation exchange capacity was determined in a 1.0 m ammonium acetate extract (pH 7) with a flame atomic absorption spectrophotometer (M6, Thermo Scientific, Waltham, MA, USA) (Luo et al, 2016b).…”

Biochar has attracted global attention because of its widespread application to improve soil quality and enhance soil productivity. Five types of biochar were prepared from peanut shells at 200–600°C by slow pyrolysis, and their physicochemical properties were investigated. Biochar was produced at 300 and 400°C, PBC300 and PBC400, respectively. The two forms of biochar were evaluated as soil amendments with an incubation and a pot experiment in a soil that had become acidified because of excessive use of nitrogen (N) fertilizers. The PBC300 and PBC400 additions significantly decreased the soil bulk density and increased the pH, cation exchange capacity (CEC) and soil organic matter (SOM) content. Both types of biochar significantly decreased NH4+‐N and NO3−‐N contents as a result of N immobilization, reduced nitrification because of the enhanced microbial activity (determined by the fluorescein diacetate method) and reduced the abundance of ammonia‐oxidizing bacteria (AOB). The growth of maize (Zea mays L.) was stimulated and, compared with the unamended soil, the biomass increased by 15.2–32.7% following the addition of PBC300 or PBC400. Maize root morphology (e.g. length and tips) and the properties of the rhizosphere soil (e.g. CEC and pH) were improved by the addition of biochar, leading to enhance N bioavailability by decreasing NAE (N accumulation efficiency) and increasing NUE (N utilization efficiency). In general, the ameliorating effects of PBC400 on the acidic soil were superior to those of PBC300. These results indicate that producing a specific type of biochar based on pyrolytic temperature might be an alternative strategy for selecting the most appropriate biochar for a specific soil. Highlights Biochar was selected for an acidic soil based on the pyrolytic temperature. Biochar decreased the soil bulk density and increased the soil pH, CEC and SOM. Biochar slowed nitrification by decreasing the abundance of ammonia‐oxidizing bacteria (AOB). Adding biochar stimulated maize growth and improved N bioavailability.

“…In contrast, biochar as a material endowed with a sizeable amount of carbon, which is generated from pyrolysis process at a hefty temperature ranging from 300 to 1000 o C under either constrained or free-oxygen environment (Verheijen et al, 2010), is also considered soil amendment, which has been proven to be recalcitrant to microbial activity than organic materials (Zimmerman, 2010), and thereby resulting in long-term organic matter maintenance in the soil. It was revealed that biochar possesses a tremendous perk in enhancing soil physical and chemical properties (Luo et al, 2017), due to being endowed with good physical condition, such as high porosity and surface area (Van Zwieten et al, 2010). Rillig & Thies (2012) found that biochar application enhanced physicochemical soil properties due to being endowed with a high porosity, surface area and able to adsorb organic matter and plant nutrients.…”

The profitability of a sandy clay loam (SCL) soil is well known to be constrained due to poor aggregation and aggregate stability, rapid infiltration and drainage of water, as well as low capability of retaining water and nutrients, and thereby culminating in decreased water and fertilizer use efficiency, which in turn decrease agricultural production. Thus, organic materials have long been reported as a promising avenue for addressing the aforementioned difficulties in different soil types. In this regard, the aims of this study were to determine the effect of applying Oleaster tree pruning residues (OPR) in two the different forms (compost and biochar) as an organic material on improving aggregation and water retention characteristic of a SCL soil. Biochar was obtained from OPR through pyrolysis process at 450 0 C, while compost was obtained from composting of the OPR through windrow composting process. Compost and biochar were individually applied to a SCL soil at a rate of 0, 1, 2 and 4% (wt/wt) with four replications and thoroughly mixed with the soil, then moistened to field capacity (FC) equated to 0.29 g g -1 and subsequently incubated for the period of two months. At the end of incubation period, obtained experimental results indicated that applied compost and biochar significantly improved aggregation and water retention characteristics of a SCL soil and improvements were proportional to application rates. We concluded that both applied forms of the OPR (compost and biochar) could be considered leading soil amendments for improving aggregation and water retention capacity of a SCL, and thereby enhancing agricultural production.
