“…Most rocks have a density of 2.65 g/cm 3 . Ideally, silt loam should have 50% pore space and 1.33 g/cm 3 bulk density (Suzuki et al, 2022). High organic matter content, well-aggregated, porous soils typically have lower bulk density, as observed in this study.…”

“…Soil compaction is indicated by bulk density. Soil processes and productivity are influenced by infiltration, rooting depth, water capacity, soil porosity, aeration, nutrient availability, and microbial activity (Suzuki et al, 2022). The bulk density of soil is its oven-dry weight per unit volume at field moisture capacity or prescribed moisture content.…”

“…The study soils have high bulk density for several causes, such as low organic carbon and horizon development with cementing agents. Management strategies can modify bulk density by affecting soil cover, organic matter content, structure, compaction, and porosity (Suzuki et al, 2022). Excessive tillage degrades soil organic matter and decreases aggregate stability, making them vulnerable to water and wind erosion.…”

Egypt's land resources deteriorate due to soil mismanagement under the limited natural resources while the population increases. This issue highlights the importance of efficient soil resource management to increase crop yield and meet growing food needs. This study offers sustainable soil resource management for each soil type in Wadi Wardan, Suez Gulf region, South Sinai, Egypt, maximizing land usage and crop output while avoiding soil degradation. Wadi Wardan, spanning 300 km 2 , is believed to hold promising soil resources in South Sinai. From upslope to downslope, five landforms were mapped in Wadi Wardan: the recharge area of Wadi tributaries (33 km 2 ; unsampled), pediment (105 km 2 ), fluvial plain (54 km 2 ), Wardan's delta (87 km 2 ), and coastal plain (21 km 2 ). Eightynine pedons were proportionally dispersed over only four landforms in Wadi Wardan. Soils range from shallow to deep, with well-drained to poorly-drained conditions. The studied soils were coarse-to-fine in texture. Soils range from nonsaline on upslopes to very strongly saline on downslopes. The studied soils rangefromslightlytoextremelycalcareous.Highρbvaluesandloworganiccarbonlevelsindicated soil problems in Wadi Wardan. Six mapping units were established depending on soil depth, texture, salt, and lime content. Based on WRB soil taxonomy, most soils in the pediment and fluvial plains are classed as Leptosols (69.3 km 2 ), Regosols (42.5 km 2 ), and Calcisols (39.7 km 2 ), while those in Wardan's delta are Sololnetz (43 km 2 ) and Solonchaks (51.5 km 2 ). Coastal plain soils are classified as Arenosols (21 km 2 ). Based on WRB, Solonchaks has a horizon sequence of A-Btz-C/Bt-Cz containing salic horizon and soil limitations related to high salinity content (9.1-21.1 dS/m). Natric and salic horizons in Sololnetz's Ap-E-Btnz-C sequence indicate sodium and salt restrictions. The Arenosol layer sequence (A-Ck-Cq-Cz-Cφ)suggestsdeepsandy-saline soil, while the Leptosol layer sequence (C-Cφ)showsshallowsandysoil with over 30% rock fragments. Each soil type requires unique management depending on dominating features that limit plant development. The current study proposed a sustainable soil management framework for each soil type identified in the study. Incoherence, nutrient storage, and erosion sensitivity plague Arenosols. Salts affect three types of soils under study to varying degrees: saline sandy soils (Arenosols) with a coarse texture that end at a depth of 172 cm, and salts are concentrated in the lower layers (Cz layer at a depth of 106-153 cm) of the pedon, reaching more than 27 dS/m. The strongly saline soils, particularly in the upper 50 cm of the pedon, have a moderately fine textured soil, particularly in the salic horizon (Btz) in Solonchaks, which finishes at 149 cm deep. The third kind is represented by Sololnetz with a fine texture, and it is the most harmful because it combines high salinity and high alkalinity in the fine texture of the soil, as in the Btnz horizon at a depth of 57-100 cm. Each of these soil types has a uni...

This study investigates the soil organic carbon (SOC) and whole tree biomass carbon (C), soil bulk density (BD) as well as changes in these parameters in afforested areas in Latvia. The study covered 24 research sites in afforested areas—juvenile forest stands dominated by Scots pine, Norway spruce and Silver birch. The initial measurements were conducted in 2012 and repeated in 2021. The results show that afforestation mostly leads to a general decrease in soil BD and SOC stock in 0–40 cm soil layer and an increase in C stock in tree biomass across afforested areas with various tree species, soil types, and former land uses. The physical and chemical properties of the soil could explain the differences in changes in soil BD and SOC caused by afforestation, as well as the impact of past land use may have persisted. When comparing the changes in SOC stock with the increase in C stock in tree biomass due to afforestation, taking into account the decrease in soil BD and the resulting elevation of soil surface level, the afforested areas at juvenile development stage can be considered a net C sink.

“…The plant P was solubilized using the H 2 SO 4 -H 2 O 2 wet digestion method, and P was quantified by the vanadium-molybdenum method. The soil bulk density was measured after wheat and faba bean were harvested each year as follows: a ring knife was used to cut a natural soil sample from the plot, and brought back to the laboratory, dried in an oven at 105 • C, then we calculated the dried soil weight per unit volume [34]. Subsequently, 5-point (diagonal) and 10-point sampling methods were used to collect soil from a 0-20 cm depth in monoand inter-cropped plots.…”

Background and aims: This research aimed to evaluate the effects of consecutive intercropping on soil phosphorus (P) partitioning, concentrations, and sensitivity to P fertilizer application, elucidating its impact on soil P bioavailability. Methods: A field experiment investigated soil P fractions and content under continuous wheat and faba bean intercropping. Three P levels (0, 45, and 90 kg P2O5 ha−1 denoted as P0, P1, and P2, respectively) and three planting patterns (monocropped wheat (MW), monocropped faba bean (MF), and wheat and faba bean intercropping (W//F)) were established since 2014. Aboveground P uptake by wheat and faba bean was determined. The soil P fractions and content were analyzed after six-, seven-, and eight-year continuous field experiments. Results: Wheat and faba bean intercropping increased wheat aboveground P uptake by 28.3–42.7% compared to MW under P1 and P2 levels and presented a P uptake advantage (LERPuptake > 1), although W//F had no impact on faba bean P uptake. Consequently, continuous intercropping for 8 years decreased soil available P reserves by 9.0–23.4% in comparison to the weighted average value of MW and MF (It). Faba bean consumed greater non-labile and labile P than wheat with low P input. W//F had nearly no impact on the labile P pool but reduced the non-labile P pool by 5.0–12.1% under all P levels and lowered the moderately labile P pool by 1.7–4.7% at P0 and P1 levels compared to It with consecutive intercropping for 8 years. Consecutive intercropping of wheat and faba bean primarily decreased the proportion of Resin-P in the labile P pool and the proportion of Residual-P in the non-labile P pool. According to the structural equation model, crop P uptake mainly originated from soil available P, which was directly affected by non-labile P (Residual-P and Conc. HCl-P). In addition, intercropping changed the contribution of each P faction to crop P uptake compared to MW and MF, and P uptake in intercropping primarily depended on Conc. HCl- P and Dil. HCl-P. Therefore, consecutive intercropping decreased soil non-labile P and drove soil available P depletion, and intercropping’s increase of P uptake was related to the non-labile P mobilized to moderately labile and labile P. Conclusions: Continuous wheat and faba bean intercropping reduced non-labile P and led to soil available P depletion under low P input. This practice stimulated non-labile P mobilization, enhancing soil P fraction effectiveness and facilitating P uptake in intercropping. Continuous intercropping of wheat and faba bean is as an effective method to maximize the biological availability of soil P and reduce P application rates.
