“…Our locally produced biochar is a mixture of different particle sizes ( Table 1 ) which positively affects porosity at all levels, including micropores, mesopores, and macropores. The variety of biochar particle sizes is beneficial for improving soil porosity, as discovered by Alghamdi et al [ 39 ], who identified a correlation between the size of biochar particle size and its impact on soil pores. Liu et al [ 40 ] also reported that each pore size specifically affects soil water retention.…”

Poor agricultural soil management practices and water use optimisation in irrigation are major challenges facing crop production in Senegal. To address these problems, a factorial experiment was conducted in 2021 and 2022 to investigate the effects of biochar on tomato growth and yield in sandy loam soil under different irrigation levels. Treatments included three biochar treatments (B2 = 30 t·ha−1, B1 = 15 t·ha−1, and B0 = 0 t·ha−1) and three irrigation levels (full irrigation, W0 = 8 L·m−2·day−1; medium deficit irrigation, W1 = 6 L·m−2·day−1, which is 75% of W0; and deficit irrigation, W2 = 4 L·m−2·day−1, 50% of W0). The results showed that using biochar at 30 t·ha−1 significantly (P < 0.05) reduced the bulk density of the soil by up to 8.3% under W1. In addition, biochar at 15 t·ha−1 and 30 t·ha−1 enhanced, regardless of the amount of water applied, the growth of tomato plants by at least 14% compared to that in the B0 treatment. Furthermore, the tomatoes’ yields in biochar treatments B1 (12.58 t·ha−1) and B2 (12.45 t·ha−1) under W2 were greater than those under B0 (9.27 t·ha−1) under full irrigation. The combinations of biochar and the lowest irrigation water level (W2 and B1 or W2 and B2) can therefore allow a water economy of up to 50% of full irrigation without compromising yield. Our study concluded that biochar could sustainably reduce agricultural water consumption while increasing yields. To further understand the influence of biochar on sandy loam soil, more research is needed on its effects on soil moisture content at permanent wilting points and field capacity.

“…These enhancements improve soil quality, increase water use efficiency, and reduce water stress on crop yields. Alghamdi et al 4 , 5 reported a significant decrease in soil-saturated hydraulic conductivity for all treatments compared to control after adding biochar produced at different pyrolysis temperatures and application rates.…”

Biochar is increasingly recognized for its ability to enhance hydro-physical properties of soil, offering promising solutions for improving soil structure, water retention, and overall agricultural productivity. In this study, sandy loam soil was amended at different rates (0, 15, 30, and 60 t ha−1) of biochar produced from olive pomace (Jift) at different pyrolysis temperatures (300, 400, 500, and 600 °C), and incubated for 30, 60, and 90 days. The biochar-amended soils were collected for analysis after each incubation period for infiltration rate, aggregate stability, soil water retention, water repellency, and penetration resistance. At 300 °C, aggregate stability increased with biochar amendments; the highest value (65%) was after 60 days of incubation. At other pyrolysis temperatures, aggregate stability decreased, or no effect of temperature was observed. Also, at 300 °C, the infiltration rate was decreased with biochar application and the lowest value of (0.14 ml/min) was at 90 days of incubation. At other pyrolysis temperatures, the infiltration rate was increased with increased biochar application rate. Water retention was increased with biochar application at 300 °C; however, biochar application did not affect water retention at other pyrolysis temperatures. These results strongly suggest the improvement of soil physical and hydraulic properties following the addition of biochar amendment. Overall, biochar had positive effects on hydro-physical properties. The biochar produced at 300 °C pyrolysis temperature was the most beneficial to agriculturally relevant hydraulic conditions. However, field assessments are necessary to evaluate the long-term effects of biochar on hydro-physical properties.

“…Practices which could decrease the amount of irrigation water, without reducing yield, are required, especially in arid environments [3,5]. Therefore, the partial root zone drying (PRD) method, regulated deficit irrigation (RDI), and the addition of soil conditioners, such as biochar, are considered important approaches that can conserve irrigation water and increase yields and water productivity (WP) [6][7][8][9][10].…”

The impacts of regulated deficit irrigation (RDI) and partial root zone drying irrigation (PRD) on water productivity (WP), crop water response factor (Ky), and yield of tomato crop (Solanum lycopersicum) were explored in this study using fresh (0.9 dS m−1) and saline (3.6 dS m−1) water under greenhouse conditions. RDI had four ETc (crop evapotranspiration) levels, i.e., 40, 60, 80, and 100%. PRD adopted 100% ETc for all treatments with changes in its application time (first, second, third, and fourth growth stages). Biochar pyrolyzed at 450–500 °C and added at rate of 4%. The results revealed that the Ky ranged between 0.21 and 0.37, indicating that tomato can tolerate a shortage of irrigation water. The highest value of WP (191 kg m−3) was found in 40% ETc using fresh water with biochar. The highest yield (20.0 kg m−2) was obtained with the application of 100% ETc with fresh water and biochar. Biochar application did not result in favorable yields with saline water due to its high salinity (7.8 dS m−1). The use of PRD in the fourth stage with biochar and fresh water led to the highest yield (20.6 kg m−2). Finally, this study recommends the application of biochar only when fresh irrigation water is available in adequate amounts.
