“…The lowest effects on both parameters were recorded with application of PL (1.1 and 1.1%, respectively) or BC (1.7 and 1.6%, respectively) when compared to the control. These results are agreed with that obtained by Ibrahim et al (2015), Kheir et al (2017), Alkhasha et al (2018) and Riad et al (2018) who observed that soil amendments improved hydro-physical properties of sandy soils in lysimeter experiment such as water holding capacity.…”

“…Also, using PL improves land and water productivity, evaporation and infiltration rates (Ekebafe et al, 2011), while it with BC enhances its positive effects on plant growth (Ruqin et al, 2015) whereas, the germination rate was 76.9-83.7% with BC alone, increased to 83.6-85.8% with BC+PL, through inhibiting the rise of pH and EC due to BC application. Alkhasha et al (2018) reported that 0.2-0.8% PL and 2-8% BC improved hydro-physical properties of sandy soil, whereas mixture of 0.8% PL with 8.0% BC resulted in the highest increase in soil moisture content at field capacity.…”

T HE DROUGHT is one of the most important abiotic stresses limiting the crop productivity especially in sandy soils in arid and semi-arid areas. So, using soil amendments such as vermicompost (VC), biochar (BC), and polymer (PL) are more important in these areas. Lysimeter experiments with sandy soil were carried out at Sakha Agric. Res. Station, Kafr El-Sheikh, Egypt to study the effect of 0.4% PL, 4.0% VC and 1.0% BC (W:W soil) on productivity of wheat (2018/019) and maize (2019) under two irrigation levels (irrigation after depletion of 50% and 75% from soil moisture. The obtained results indicated that irrigation at 75% moisture depletion (irrigation deficit) decreased plant height, 100-grain weight, grain and straw yields, water applied to wheat (-16.8%) and maize (-20%) compared to that with higher irrigation level (50% depletion). Also, water productivity was slightly decreased for wheat, but it slightly increased for maize and ECe values were slightly increased due to irrigation deficit. Also, applications of soil amendments and their combinations significantly increased plant height, 100-grain weight, yield and water productivity of both crops and improved soil porosity and field capacity. The VC was more effective treatment followed by BC and PL treatments, while their interactions were the most effective on these parameters. Moreover, soil amendments alleviated the deleterious effects of irrigation deficit on plant growth and salt accumulation. Finally, applying BC combined with VC and PL could be recommended as a good approach to maintain long-term productivity of sandy soils and mitigate the hazardous effects of drought stresses.

“…Biochar also has the potential to improve soil hydraulic and physical properties, including porosity, available water, soil aggregate stability, hydraulic conductivity, infiltration rate, and water retention at higher and lower tensions (Alkhasha et al., 2018; Obia, Mulder, Martinsen, Cornelissen, & Børresen, 2016). Most studies evaluated the effect of biochar application on several soil hydraulic properties and water retention in the wet range of sandy soil (Brockhoff, Christians, Killorn, Horton, & Davis, 2010; Zhang, Chen, & You, 2016).…”

“…Thus, biochar can be used as a soil amendment in agricultural lands to improve soil quality (Kizito et al, 2019;Laghari et al, 2015;Tanure et al, 2019), reduce organic waste, and recover nutrient and energy from what would otherwise be unused byproduct (Basiri Jahromi, Walker, Fulcher, Altland, & Wright, 2018;Kizito et al, 2019). Biochar's ability to improve water retention can ameliorate soils in arid regions that experience water scarcity and quality issues (Alkhasha, Al-Omran, & Aly, 2018).…”

Seasonal flooding following heavy rain deposits large amounts of sediments on productive lands in the lower parts of fields in western Tennessee. The deposited sediments have high proportion of sand particles that negatively affect soil physiochemical properties, which make the soil uneconomic for farming. Soil amendments such as biochar, a by‐product of renewable energy production from organic waste materials, have the potential to remediate sandy soil left after flood events and improve crop yields by increasing water holding capacity and soil nutrient content. The objective of this project was to evaluate the effect of biochar produced from two types of hardwood feedstocks on water retention and corn (Zea mays L.) growth in sandy soil. A greenhouse experiment quantifying the growth of corn was conducted in a randomized complete block design with five replications. Sandy soil was amended with three biochar rates (0, 10, and 20% by volume) under two irrigation levels. The irrigation levels were control and a dry treatment based on the past 10 yr of rainfall data. Biochar application greatly improved water retention in the flooded sandy soil. Biochar increased soil K and P concentration. However, at the end of the study, corn growth was not different in biochar amended and non‐amended sandy soil. This research demonstrated that biochar as a soil amendment has the potential to improve quality attributes of poor soil, such as the soil water and nutrient concentration in a previously flooded sandy soils.

“…Along with advances in irrigation scheduling (Nikolaou et al 2019), the application of non-traditional soil amendments [defined here as non-fertilizer materials applied to a soil or substrate to improve production, vigor or growth (NCR-103 Committee Report 2004)] offers a management option that may help sustain production. The amendments studied include: humic acid-based root stimulants (Xu et al 2014), composted waste products (Kandal et al 2016), hydrophilic gels (Alkhasha et al 2018) and modified organic materials such as biochar (Darling 2015). There is, however, another group of substances that possesses beneficial properties when used as soil or substrate amendments.…”

Humectant treatment and substrate moisture content (SMC) were studied to determine their impact on post-transplant water utilization in ‘Thumbelina' zinnia (Zinnia elegans Jacq.). Four-week-old seedlings were transplanted from plug trays into pots containing soilless substrate amended with an aqueous solution of 1.6% Hydretain® or an equal volume of water (0% humectant). Seedlings were placed in an automated, sensor-controlled irrigation system and grown for 30 days at SMC levels of 0.45 or 0.25 cm3·cm−3 (0.06 or 0.03 fl oz·oz−1). Plant-water potential (Ψw) was significantly higher (less negative) in transplants grown in humectant-treated substrate at both SMC levels, and water-use efficiency (WUE) was 2X greater for seedlings grown in treated substrate maintained at 0.25 cm3·cm−3 than it was for transplants grown in untreated substrate at the same SMC level. No significant differences in height, stem diameter or shoot dry weight were observed when comparing plants grown in treated and untreated substrate. Root dry weight was significantly greater for seedlings grown in untreated substrate. Flowering was not affected by humectant treatment or by SMC. The results show that transplanted zinnia ‘Thumbelina' seedlings require less irrigation when grown at a lower SMC threshold in soilless substrate amended with 1.6% Hydretain®. Index words: automated irrigation control, cultural practices, plant-water relations, transplant establishment, water management, water-use efficiency. Species used in this study: ‘Thumbelina' zinnia (Zinnia elegans Jacq.). Chemicals used in this study: Hydretain® - a proprietary blend of sugar alcohols, polysaccharides, and neutral salts of alphahydroxyproprionic acid.
