“…Consequently, the retained water, which is a good indicator for the availability of water in the soil for plant uptake, was increased as compared to the control (Tables 5 and 6). Similar results were found by Ibrahim et al [7], Ibrahim et al [8], Al-Omran et al [9], and Alghamdi et al [ 3 Available water (AW = FC − PWP); 4 Mean separation within each column by uncan's multiple range test (DMRT). The treatment with same letter is not significant at 5% level; 5 Sorptivity was calcuated by fitting a second order polynomial to the plot of cumulative infiltration versus the square root of time (Fiure 7).…”

“…In comparison to the control, cumulative evaporation decreased for all biochar treatments, while the retained water amounts increased. The highest decrease of retained water, after 35 days, was observed for the B505 and L505 treatments, scoring 37.3 and 37.4 mm, respectively, while the highest increase was recorded for the B405, B505, and L505 treatments, reaching 18.8, 18.7, and 18.7 mm, respectively [4,6] (Table 4 and Figure 3). All types of biochar increased the ability of the soil to hold water, with exceptions of B401, B305, and B405 (Figure 3), and the highest increase was observed for B505 and L505, followed by L501.…”

“…The EC of the biochar prepared from leaves increased from 0.62 to 5.07 dS m −1 when the pyrolytic temperature increased from 300 • C to 500 • C. Biochar characterized by a high salinity such as that used in the L500 treatment, can cause a large increase in soil salinity, especially when used in arid environments. Consequently, these types of biochar should be avoided under saline conditions [4,6]. However, biochar prepared from olive branches, using all the three experimental pyrolytic temperatures, had a low salinity, which reveals this biochar type to be safely employed under saline soil conditions.…”

“…More integrated research and investigation of sustainable technology concepts have been conducted. Biochar, a soil amendment, is defined as a rich carbon product produced by pyrolysis of organic residues under limited oxygen conditions [4,5]. The biochar is resistant to soil microorganism's decomposition; consequently, has two environmental benefits; enhancing soil quality and productivity, and acting as a sink of carbon, leading to a decrease in the emissions of greenhouse gas into the environment and an increase in crops production [6][7][8].…”

In this study, waste olive leaves and branches were pyrolyzed to produced biochar, and their impacts on physical and chemical properties of a sandy soil were evaluated. Pyrolytic temperatures of 300 °C, 400 °C, and 500 °C were used for biochar production. After evaluating the physio-chemical properties, the produced biochars were added to the top 10 cm layer of the soil at rates of 0%, 1%, 3%, and 5% in a column experiment at 25 °C. Biochar was mixed with a sandy soil into the top 10 cm of the columns. For all treatments, cumulative evaporation was reduced; however, treatments with 5% biochar prepared at the highest temperatures showed the highest impact. The available water contents were increased by 153.33% and 151.11% when olive branch-derived biochar and olive leaves-derived biochars produced at 500 °C were applied at 5% rate, respectively. No impact of available water was observed for 1% biochar contribution. Biochar application decreased both cumulative infiltration and infiltration rate. Biochar pyrolyzed at 500 °C most intensely improved hydro-physical properties of a sandy soil. However, its application as a soil supplement in arid environments should be adopted with constraints due to its high pH (9.69 and 9.29 for biochar pyrolyzed at the highest temperatures) and salinity (up to electrical conductivity = 5.07 dS m−1). However, the salinity of biochar prepared from olive branches (5%, pyrolyzed at 500 °C) was low (0.79 dS m−1); therefore, it can be used safely as a supplement in saline and acidic soils, but with restriction in alkaline soils.

Date palm production contributes significantly to socio-economic development and food security in the dryland areas of Southern Tunisia. Soil degradation and nutrient depletion have dramatically increased in recent years. This is leading to a decline in date palm yields in these oases-based production systems. Locally derived bentonite clay has been identified as a new soil amendment to improve date morphological characteristics and date production. In this study, a 3-year field experimental study was carried out on 3-year-old Deglet Nour date palms growing in sandy soil of a Tunisian oasis (Fatnassa, Southern Tunisia). The study's aim was to compare the effect of two amendment types: (i) sand (S) mixed with farm manure (M) and bentonite clay (B) (=BSM) and (ii) sand mixed with farm manure (SM) on the soil characteristics and morphological features of date palm. The results indicated that soil macro-and micronutrient contents were enhanced under BSM. Soil water retention in BSM also increased to 290 ± 0.3 mm m −1 compared to 70 ± 0.2 and 50 ± 0.5 mm m −1 for an untreated (no amendment) and SM treatment, respectively. The amelioration of morphological characteristics was observed for the canopy diameter reaching 226 ± 0.6 cm in BSM treatment compared to 172 ± 0.6 cm in untreated palm trees. The height of the palms increased by 69 ± 0.8 cm from 29 ± 0.1cm in the control treatment, and leaf number increased from 40 leaves palm −1 in BS to 60 leaves palm −1 in BSM treatment. The leaf mineral content was significantly been improved in the third year, and the leaf NPK contents were 220 ± 0.6 mg kg −1 , 17 ± 0.1 mg kg −1 , and 200 ± 0.04 mg kg −1 , respectively, in BSM treatments. The effect of the farm manure and bentonite clay was noticeable for the yield production, and the SM and BSM treatments offered yields of 70 ± 0.9 kg palm −1 and 80 ± 0.5 kg palm −1 , respectively. It could partly ameliorate the alternate year bearing phenomenon of the Deglet Nour date variety. We conclude that the joint application of farm manure and bentonite clay does represent a viable option to further improve the production and resilience of date palms in dryland areas.
