“…BD was determined at 0-10 cm and 10-20 cm soil depth intervals. Land use conversions from natural forests to managed lands affect the compaction, porosity, and BD in soil (Kar et al 2022). BD was in the order of field road > agricultural land > natural forest (tables 1 and 2).…”

The complex nature of podzolic soils makes investigating their subsurface challenging. Near-surface geophysical techniques, like electromagnetic induction (EMI), offer significant assistance in studying podzolic soils. Multi-coil (MC-EMI) and multi-frequency (MF-EMI) sensors were selected to maximize soil water content (SWC) prediction in this study. The objectives were to (i) compare apparent electrical conductivity (ECa) measurements from the MC and MF-EMI sensors under different land use conditions, (ii) investigate the spatial variation of ECa, SWC, texture, soil organic matter (SOM), and bulk density (BD) under different land use conditions, and (iii) use statistical and geostatistical analysis to evaluate the effectiveness of ECa measurements in characterizing SWC under different land use conditions, considering the texture, SOM, and BD contents. The study found that MC-EMI had statistically significant relations (p-value  0.05) with SWC relative to the MF-EMI. Multiple linear regression (MLR) models were also shown to be more effective in representing SWC variations (higher coefficient of determination and lower root mean square error) than simple linear regression models. MC-EMI sensor provided better SWC predictions compared to the MF-EMI sensor, possibly due to larger sampling depths differences between time domain reflectometry measured SWC (SWCTDR) and MF-EMI sensor than those between SWCTDR and MC-EMI sensor. Lastly, cokriging of measured SWC was found to offer more accurate maps than cokriging of predicted SWC obtained from MLR across different land use conditions. The study has shown that EMI may not be highly effective for shallow depths, and ECa can be affected by various soil properties, making it difficult to extrapolate other parameters. However, EMI still shows promise as a reliable method for predicting SWC in boreal podzolic soils. Research into EMI's usefulness for this purpose has yielded promising results, as indicated in this study. Further investigation is needed to fully harness the potential of this promising technique.

“…For the rice-rice rotation, the highest bulk density was 1.53 g cm -3 in the 30cm soil layer (p = 0.001), followed by a gradual decrease and ended up with the value of 1.23 g cm -3 at the 100-cm soil layer. Kar et al (2023a) conducted a study in the northwestern Indian Himalayas with four treatments, namely control, conventional tillage, zero tillage, and reduced tillage, and quantified that bulk density in the conventional tillage system was higher among the treatments. Chen and Liu (2002) conducted a study in rice fields containing silt loam soil in Taiwan and found that the bulk density for 20-30 cm soil depth was 1.51 g cm -3 .…”

Recurring puddling for long-term rice cultivation forms a plow pan at a particular soil depth, which alters soil hydraulic properties, field-scale hydrology, and nutrient persistence in the soil. This experiment aimed to assess the impact of long-term rice cultivation on root-zone soil hydraulic properties and field-scale hydrology. Soil core samples were collected from four land management options namely, rice‒rice, non-rice, rice and non-rice, and field ridge, at two sites, one with loam and another with silt-loam soil. The soil cores were sampled for each 10 cm layer up to 100 cm depth from three locations of each rotation at both sites. Soil hydraulic parameters were estimated using a pedotransfer function based on the measured bulk density and soil texture. A mathematical model named HYDRUS-1D predicted infiltration, percolation, and surface runoff with the estimated hydraulic properties for three extreme rainfall events, i.e., 3.33, 5, and 6.66 cm hr-1, during a 3-hour period. A plow pan was found at 20–30 cm soil depth for all the land management options but not for the field ridge. The plow pan of the rice‒rice rotation had the highest bulk density (1.53 g cm-3) and the lowest hydraulic conductivity (17.56 cm day-1). However, the top 10 cm soil layer in the rice–rice field had the lowest bulk density (0.93 g cm-3). At both sites, the field ridge had higher infiltration and percolation and lower runoff than other rotations. The study reveals that the field-ridge area of a rice field can be the main water loss pathway. Phosphorus concentration in the rice-rice rotation decreased from 7.7 mg kg-1 in the 10-cm soil layer to 2.49 mg kg-1 in the 100-cm layer. These findings will facilitate making better water management decisions.

“…Land degradation due to unscientific land uses leads to the deterioration of soil hydro‐physical properties (bulk density [BD], porosity, aggregate stability, hydraulic conductivity, etc. ), which necessitates the adoption of site‐specific land management practices to restore soil health (Kar et al, 2023). In India, around 120.7 M ha of land is degraded (68% due to water erosion) (Maji et al, 2010), resulting in a loss of 5.3 GT soil year −1 (Narayana & Babu, 1983).…”

A long‐term experiment (1995–2021) was conducted on litchi (Litchi chinensis L.) with and without conservation practices, that is, litchi under clean cultivation (LCC) (recommended doses of fertilizers without intercrops and mulch) and litchi with conservation practice (LCP) (micro‐site improvement, intercrops, and organic mulching) on degraded lands. The study aimed to evaluate the long‐term impact of litchi‐based land uses on vegetative growth (plant height, canopy volume, fruit yield, and litter production), soil moisture, biomass production, carbon stocks (CS), and soil qualities (enzyme activities, microbial counts, and soil fertility). The results revealed that LCP improved vegetative growth, yields, and soil moisture over LCC. The total dry biomass was observed 91.6–103.9, stored CS; 43.6–49.4, emitted CS; 7.04–9.40, mitigated CS; 30.1–30.5, soil CS; 35.7–39.9, total CS (soil + vegetation); 65.9–70.5 Mg ha−1 and carbon dioxide mitigation; 88.3–112.1 Mg ha−1 in LCC and LCP land uses, respectively. Further, in LCP, beta‐glucosidase, acid phosphatase, alkaline phosphatase, and dehydrogenase activities increased by 17.2%, 20.4%, 19.8%, and 24.8%, respectively, in surface soil compared with LCC in 2021. Likewise, the microbial density of bacteria, fungi, and actinomycetes was also observed to be 20.2%, 41.4%, and 19.5% higher, respectively, in LCP land use in 2021 over 2015. Similarly, available N, P, and K increased by 19.9%, 75.3%, and 36.8% under LCP from 1997 to 2021. Hence, litchi‐based land use with conservation practices can be advocated to rehabilitate and improve the soil health of degraded lands and enhance ecosystem services in similar edaphoclimatic conditions.
