“…Soils in the arid and semi-arid regions of Iran are alkaline, deficient in organic matter, and mostly calcareous. Consequently, most plants in these soils suffer from deficiencies of key nutrients, including phosphorous (P), iron (Fe), and zinc (Zn) [1]. These nutrient deficiencies are common in arable lands around the world [2][3][4][5][6][7] and have negative impacts on many aspects of human health, including growth, reproduction, immune responses, and the development of neural behaviors [8][9][10][11][12].…”

To identify effective ways of increasing the yield of crops grown in nutrient-poor calcareous soils, the combined effects of biochar addition and inoculation with plant growth promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF) on wheat growth and soil properties were investigated under rhizobox conditions. Measured soil properties included pH, electrical conductivity (EC), organic matter content (OM), the availability of P, Fe, and Zn in the rhizosphere, and the uptake of these elements by plants. Combined biochar addition and microbial inoculation were shown to significantly increase the concentration of available forms of P, Fe, and Zn in the soil when compared to non-biochar treatments. The highest soil pH (7.82) was observed following biochar addition without microbial inoculation. The EC following biochar addition and PGPR inoculation was significantly higher than the other treatments, and the soil OM content was highest when combining AMF inoculation with biochar addition. The available P content after AMF inoculation combined with biochar addition was 27.81% higher than the control conditions, and AMF inoculation increased Fe and Zn bioavailability by factors of 2.38 and 1.29, respectively, when combined with biochar addition relative to AMF inoculation alone. The simultaneous biochar addition and PGPR inoculation significantly increased P uptake by the plants. The highest shoot Fe and Zn uptake rates were observed after a simultaneous application of biochar and PGPR inoculation. Under these conditions, shoot uptake was higher than seen when combining biochar addition with AMF inoculation by factors of 1.64 and 1.21, respectively. In general, it can be concluded that combining inoculation with growth-promoting bacteria and biochar addition can effectively improve nutrient availability to plant and soil conditions.

“…Differences in total leachate volume among soils may be attributed to the differences in their ability to hold water (Sadeghizadeh & Jalali, 2017). Clay particles in the sandy loam can help to retain the water in the soil (Osman, 2012), and more organic material in the Fafard 3B-SURF can increase soil water capacity (Minasny & McBratney, 2018;Moskal et al, 2001), subsequently resulting in the less leachate compared with the sand and sand-peat soils.…”

Water retentionx is considered an important characteristic for determining the efficiency and effectiveness of soils and greenhouse substrates. Surfactants have the potential to improve water infiltration and distribution uniformity throughout the soil profile. In addition, efficient irrigation can improve the wettability of soils. The objective of this study was to determine how surfactants and irrigation influence soil water content (SWC), leachate volume, and pH in soils and greenhouse substrates.This study was conducted at Clemson University, SC, on two soils (sandy loam and sand) and two substrates (Fafard 3B-SURF and 80% sand, 20% peat). Four surfactants (a) 10% oleic acid esters of block copolymers (OAC), (b) 30% alkoxylated polyols and 21% glucoethers (APG), (c) 50% nonionic polyols and 5% 1,2-propanediol (NIPP), and (d) water control (CNT) with two irrigation regimes (ONCE and SPLIT) were applied to PVC columns. Based on the leachate results, applying irrigation volume as SPLIT in conjunction with using a surfactant reduced leachate up to 75%. The soils retained more water when OAC and NIPP surfactants were applied. When the soil was left to dry out, the SWC was 5 and 9% higher from SPLIT irrigation compared with ONCE irrigation in the sand-peat and the sand soils, respectively. Surfactants can increase SWC, and combining split irrigation with surfactants can play an important role in reducing leaching from soils and greenhouse substrates, resulting in water quality and quantity conservation, and an economic advantage to the grower.Abbreviations: APG, 30% alkoxylated polyols and 21% of glucoethers; CNT, water control; NIPP, 50% nonionic polyols and 5% 1,2-propanediol; OAC, 10% oleic acid esters of block copolymers; ONCE, irrigate on Tuesdays; SPLIT, irrigate on Tuesdays and Thursdays; SWC, soil water content.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
