“…Thus, for soils with similar texture, moisture content, and organic matter content, bulk density is a good surrogate for potential limitations to root growth and productivity. For fine‐textured soils such as those in this study, the optimum bulk density for maximum plant growth is less than approximately 1.2 g/cm 3 , with significant impediments to growth from reduced soil aeration beginning to occur above approximately 1.2 g/cm 3 , and further impediments to growth from excessive soil strength occurring above approximately 1.4 g/cm 3 (Jones ; Reynolds et al ; Wilson et al ). The average bulk density of the agricultural use sites was at this upper critical limit, with 57% of samples collected exceeding this upper limit, indicating broad‐scale spatial limitations to plant growth from high bulk density.…”

Much of the primary forest in the eastern United States that was converted to farmland between 1600 and 1900 has reverted back to second growth forest as a result of agriculture abandonment. This reversion back to forest gives soil productivity a chance to recover, though the rates of recovery are not well understood. Understanding the legacy effects of past disturbances like agriculture can provide important insights to support ecological restoration efforts on disturbed soils. Our goal with this study was to further understand the effects of forest development on soil productivity after agriculture abandonment. We used a chronosequence approach to examine soil properties over a 60‐year temporal scale of forest development on abandoned agricultural lands in Saratoga and Rensselaer Counties in New York, U.S.A. We measured soil properties within this chronosequence to test the hypothesis that there would be measurable recoveries of soil physical properties and fertility over time. We observed rapid recovery of physical properties (lower bulk density and higher macroporosity) of surface soils within 5–10 years after agricultural abandonment. However, we found a legacy effect of agricultural compaction still evident in subsoils, with soil strength measurements indicating that past agricultural practices still limited root growth 55–60 years after abandonment. Soil percent organic matter and mineralizable nitrogen (N) both increased with forest development, but biomass accumulation may be slowed by limited root growth in the subsoil due to high strength. We recommend assessing subsoil physical properties when developing ecological restoration plans for agricultural lands.

“…Tomatoes grown in clay loam typically exhibit greater growth at the highest BDs (1.5 and 1.6 g cm À3 ), whereas those grown on loamy sand showed optimum growth at 1.3 g cm À3 (Tracy et al, 2013). Wilson et al (2013) reported that the growth of wheat was limited to BD >1.4 g cm À3 in Mollisol, due to the lack of aeration. However, in this study, the moderate subsoil BD of the 15-30 cm soil layer for winer wheat was 1.55-1.57 g cm À3 in Haplic Luvisols.…”

“…Basically, it is required for predicting the SWRC and is a necessary input parameter for water, sediment, and nutrient transport models. Recently, bulk density has increasingly been used as a valuable indicator of the soil physical quality (Wilson et al, 2013). The bulk density of the soils from our study ranged from 1 to 1.8 Mg m –3 , with a mean value of 1.3 Mg m –3 (Table 2).…”

In arid and semiarid areas, the availability of reliable data for water retention in relation to soil type, texture, and soil carbonate content is low. It is therefore desirable to explore the interaction between soil hydraulic properties and other physical and chemical properties to estimate the soil water retention curve (SWRC) from easily measured soil parameters. In this study, 72 soil samples were collected from rural areas throughout northwest Syria, covering most of its agroclimatic zones and soil types. Soil water content at different matric potentials and 11 chemical and physical soil properties were determined. A Pearson correlation matrix was computed on which principal component analysis was applied to three soil water contents, −1, −33, and −1500 kPa, and the 11 soil properties. Four principal components (PCs) explained 77% of the variation in the data set. The three soil water contents were highly linked to PC1, which was correlated with the plastic limit, texture, soil carbonate content, and specific surface area. In addition, the soil water content at −1 kPa was also linked to PC4, which was correlated with bulk density. Therefore, from the initial 11 soil properties, seven contributed to the three soil water contents (plastic limit, texture, soil carbonate, specific surface area, and bulk density); the remaining four (organic matter, gravel, cation exchange capacity, and hygroscopic water content) had a negligible influence. Consequently, pedotransfer functions might be estimated using the original seven, from the initial 11, soil properties or their corresponding PCs to estimate the SWRC.
