“…Reviewed studies reported increases in CEC and organic matter in soil treated with BC; however, the magnitude of this effect varies according to the BC production condition, application rate, and soil type [3][4][5][6][7].BC use is most frequently reported to be effective in tropical zones where soils are acidic and nutrient leaching potential is high [30]. 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].…”

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 ...

“…Liming only is thus not a sustainable way to increase upland rice production, while liming combined with mineral P amendments quickly and strongly increase rice yields. It should however be regarded that both lime and TSP are often beyond reach of farmers, following market availability and costs (AGRA, 2019; Chianu et al, 2012; Raboin et al, 2016).…”

23Upland rice production on weathered soils is often constrained by phosphorus (P) deficiency and soil 24 acidity. Farmyard manure application (FYM) can sharply enhance yields and agronomic P fertilizer (TSP) 25 efficiency. We tested the hypothesis that rice genotypes differ in the extent of using organic P and offering 26 distinct benefits under TSP-FYM combinations. Multiple field trials were conducted in the uplands of 27 Madagascar, with factorial combinations of six genotypes, FYM, and TSP applications, with blanket N&K 28 additions. Rice grain yields reached 6 t ha -1 after three years of TSP+FYM application, were lower when 29 FYM or TSP were used separately, while crops failed under zero P input. Genotypic differences were 30 inferior to the large treatment effects. Application of FYM increased soil pH and CaCl2-extractable P while 31 decreasing CaCl2-extractable aluminium. An additional liming trial indicated that beneficial effects of FYM 32 over TSP relate to liming effects. Genotypic ranking of yields and agronomic efficiency was inconsistent, 33 without superior genotypes under FYM versus TSP. However, Chomrong Dhan and FOFIFA 172 showed 34 superior yields under TSP+FYM. The FYM application lowers aluminium toxicity which overrules potential 35 effects of organic P supply. Aluminium tolerance should be included when developing rice genotypes for 36 low P tolerance in weathered soils.NA Data not available. a Phosphorus Acquisition Efficiency, expressed as total P uptake in mg at low P availability in the soil. b Root Efficiency, expressed as total P uptake per unit root size (either root biomass in g or root surface area in cm 2 ).

“…Liming is an essential practice in agricultural systems (Fageria et al, 2007, Sikiric et al, 2011, Anikwe et al, 2016, Silva et al, 2016 and is widely used to increase yield in acidic soils (Caires et al, 2006, Fageria et al, 2008, Bhat et al, 2010, Kostic et al, 2015. The application of lime decreases toxic concentrations of aluminum (Al) (Steiner et al, 2012, Li et al, 2016, Raboin et al, 2016, manganese (Mn), and iron (Fe) in the soils (Sikiric et al, 2011). It is one of the most efficient and common strategies to correct the high acidity of the soil (Nelson andSu, 2010, Steiner et al, 2012).…”

Physalis is an herbaceous plant that produces edible fruits with a bittersweet flavor. This species has a high cropping potential attracting attention of farmers, traders and consumers. The effects of soil acidity indices on nutrient uptake, optimal growth, yield and fruit quality of physalis in acidic soils were evaluated. The study was conducted in a greenhouse with four lime requirements in completely randomized design and five replications. Dolomitic limestone was applied to the soils at rates of 0, 0.6, 1.4, and 2.3 t ha-1 (Typic Quartzipsamment) and 0, 0.8, 1.8, and 2.8 t ha-1 (Rhodic Hapludox). Plant height, stem diameter, shoot and root dry weight, longitudinal and transverse diameters of the fruits, macro and micronutrient concentrations in leaves, and soil chemical properties were evaluated. Liming is an essential practice for the cultivation of Physalis peruviana L. in the acidic soils, where it is aimed to achieve higher yields and quality fruit. The results highlighted the high demands of physalis for Ca, Mg, and base saturation, and low tolerance to aluminum in the soil. Maximum growth, yield and fruit quality was obtained with the application of 1.8 t lime ha-1 for both soils. The determined standards for pH in water, tolerated aluminum saturation, desired base saturation and calcium and magnesium requirements were 6.4, 5.0 %, 67 % and 25,8 mmolc dm-3, respectively.
