“…Several studies that previously investigated soil water retention in sandy soils after BC addition showed variable results [20][21][22]24,26,[56][57][58][59][60]. The results of the current study clearly indicated that the residence time of BC in soil and the pyrolysis temperature are significant factors in determining effect of BC on water retention.…”

“…Therefore, positive impact of BC on soil fertility and crop yield is not always certain, and it highly depends on FS, BC production temperature, and most importantly soil type [3,[5][6][7]20].BC benefits to soil also include improvement of soil physical properties. For instance, soil bulk density (BD) and porosity was found to be improved after BC application [20][21][22][23][24][25][26]. BC was also reported to increase the soil ability to retain water, and this is mostly attributed to the high total porosity (TP) of BC, retaining water in small pores and thereby increasing water holding capacity and infiltration [5,20,21].…”

“…Under these soils conditions, BC can have liming and nutrient availability effects, as BC was found to increase pH values of acidic soils and thereby improve nutrient bioavailability and use efficiency [7,31]. A meta-analysis using data from 103 studies found a better performance of BC addition in acidic soils than in neutral soils, and in sandy than in loam and silt soils, suggesting liming and physical property improvement effects of BC [32].Less attention has been given to effects of BC in semi-arid [33][34][35][36] and especially arid environments [26,[37][38][39][40] with few studies in true desert soils.Arid soils of Saudi Arabia are characterized in general by very low content of organic matter (<1%) and nutrients and sandy texture with poor water retention capacity and nutrient use efficiency [41]. The soils are alkaline, with a pH value in many cases found to be greater than 8.0 and have great abundance of calcium carbonate higher than 30% in some soils [41].…”

Agricultural and environmental applications of biochar (BC) to soils have received increasing attention as a possible means of improving productivity and sustainability. Most previous studies have focused on tropical soils and more recently temperate soils. However, benefits of BC addition to desert soils where many productivity constraints exist, especially water limitations, have not been widely explored. Thus, three experiments were designed using a desert soil from Saudi Arabia to address three objectives: (1) to evaluate the effect of BCs produced from date palm residues added at 8 t ha −1 on wheat growth, (2) to determine the effect of BC addition and BC aging in soil on water retention, and (3) to reveal the effect of BC on selected soil physical (bulk density, BD; total porosity; TP) and chemical (pH; electrical conductivity, EC; organic matter, OM; cation exchange capacity, CEC) properties. The feedstock (FS) of date palm residues were pyrolyzed at 300, 400, 500, and 600 • C, referred to here as BC300, BC400, BC500, and BC600, respectively. The BC products produced at low temperatures were the most effective in promoting wheat growth when applied with the NPK fertilizer and in enhancing soil water retention, particularly with aging in soil, whereas high -temperature BCs better improved the selected soil physical properties. The low-temperature BCs increased the yield approximately by 19% and improved water retention by 46% when averaged across the incubation period. Higher water retention observed with low-temperature BCs can be related to an increased amount of oxygen-containing functional groups in the low-temperature BCs, rendering BC surfaces less hydrophobic. Only the BC300 treatment showed a consistent positive impact on pH, OM, and CEC. Pyrolysis temperature of date palm residue along with aging are key factors in determining the potential benefit of BC derived from date palm residues added to sandy desert soil.crop yield is largely dependent on BC production temperature and the feedstock (FS) [5][6][7]. In a recent review, it was reported that the fertilizing value of BC and its nutrient availability, especially N and P, decrease with increasing pyrolysis temperature [5]. Therefore, the effect of BC on crop yield and plant nutrition was found to be variable, and its use as a sole amendment was not always effective, having its supplementation with mineral fertilizers sometimes necessary to promote crop growth [8][9][10][11][12][13][14][15][16]. Some studies found BC to be the most effective when it is applied with mineral fertilizers [8,14,[17][18][19]. Therefore, positive impact of BC on soil fertility and crop yield is not always certain, and it highly depends on FS, BC production temperature, and most importantly soil type [3,[5][6][7]20].BC benefits to soil also include improvement of soil physical properties. For instance, soil bulk density (BD) and porosity was found to be improved after BC application [20][21][22][23][24][25][26]. BC was also reported to increase the soil ability to retain ...

“…Biochar can improve soil porosity and specific surface area because of the macropores and micropores in biochar [36][37][38]. These characteristics may influence soil biological community [39,40], nutrient cycles [41,42], and soil structure and quality [38], and in turn promote plant growth. In the present study, the WB and PB amendments significantly increased the growth of I. aquatica Forsk.…”

The combined heavy metal pollution in vegetable fields poses a threat to food security. In this study, three types of biochar-Wedelia trilobata (WB), Pennisetum sinese Roxb (PB), and coffee grounds (CB)-were applied to a heavy metal-contaminated soil at rates of 2% and 5% (w/w). A pot experiment was conducted to investigate the effects of these three different types of biochar on the growth two Ipomoea aquatica Forsk. cultivars in the soil, and related mechanisms. The results showed that the addition of the three types of biochar significantly increased soil pH and SOM content. WB and PB significantly increased the shoot biomass of I. aquatica Forsk. The 5% WB amendment significantly decreased the plant uptake of Cd, Pb, Zn, and Ni. But PB and CB amendments at 2% or 5% showed no consistent effects on plant uptake of Cd, Pb, Cu, Zn, and Ni. The multi-factor variance analysis showed that biochar type significantly influenced Cd, Pb, Cu, Zn, and Ni accumulation in plant shoot and root and Cd, Cu, and Zn concentration in rhizosphere. Interestingly, in some of the treatments with PB and CB amendments, total available heavy metals increased, indicating that heavy metals contained in the biochar might have been released into the soil. The results indicated that biochar feedstock should be ecologically friendly.

Finding feasible solutions for sustainable food production is challenging. Here we try to understand the balance between crop productivity and ecological stewardship using agroecological‐based soil management strategies. We evaluated the potential of different organic materials such as dairy manure compost and different biochar manure co‐composts, derived locally from agricultural wastes, to enhance soil ecosystem services. We assessed their potential impact on soil moisture and nutrient retention, greenhouse gas emissions, and crop productivity using data collected from an outdoor tomato column study. Results from the experiment showed potential of biochar co‐composts to positively affect soil health by lessening loss of essential nutrients such as NO3−‐N and NH4+‐N, sustained tomato yield, and uphold crop water use efficiency. However, yield response to soil organic amendment is constrained by external factors such as irrigation strategies, with treatments under deficit irrigation greatly impacted. Overall, we observed a positive effect of adding biochar manure co‐composts to soil, although best management practices are needed to optimize crop productivity and avoid unintentional consequences.
