Soil contamination with potentially toxic elements (PTEs) in the Malwa region belt of Punjab, India, can be a serious concern as result intensive agricultural practices and overuse agrochemicals. The main objectives present study were to evaluate spatial distribution, geochemical signature, level/health risk PTEs 76 soil samples (0–10 cm) collected from three districts viz. Muktar, Faridkot, Moga India. shows that concentrations vary widely region, Fe Mn distribution patterns being mostly coherent each other. When compared Indian natural background values, average concentration Pb Zn higher than limit, only exceeded values world upper continental crust (UCC). Spatial autocorrelation plotted local indicator association (LISA) GeoDa software version 1.18 was used identify hotspots. A positive (>0.2) indicated Moran’s I for Pb, V, Mn, Cu, Cr, highest Pb. principal component analysis (PCA) identified major geo-chemical Fe-Al-V-Cr TOC-Mn-Zn-HCO3−, which positively loaded on PC1. This indicates Fe/Al-oxyhydroxides organic matter play dominant role controlling metal mobility soils. further substantiated Spearman’s rank correlation values. factor (CF) (15.7% 3.9% samples, respectively) under high risk. could due excessive application chemical fertilizers. large range degree (Cdeg) suggests there are variations pollution PTEs. little over had significant contamination, 72.3% low 23.6% moderate contamination.

Analyzing the Trade-Offs between Soil Health Enhancement, Carbon Sequestration, and Productivity in Central India’s Black Soil through Conservation Agriculture

Sustainability, Journal Year: 2024, Volume and Issue: 16(19), P. 8319 - 8319

The impact of conservation tillage (CST) practices on soil properties, carbon sequestration and yield sustainability over short, medium, long durations remain insufficiently understood, especially in semiarid Central India. Therefore, our objective was to investigate the effects optimal duration CST adoption for enhancing sequestration, sustainable yields. We conducted a study farmers’ fields Akola district India, where had been practised 4 15 years, within soybean + pigeon pea–chickpea cropping sequence. Our findings revealed significant (p < 0.05) improvements physical properties with short-term (4 6 years), alongside increasing availability nitrogen phosphorus, longer implementation (10 years). lowest organic (SOC) observed conventional (CT_y), while all increased SOC content CT_y, ranging from 22.2 38.4%. Further, experimental dominated passive C pools (Cfrac3 Cfrac4). Consequently, long-term facilitated positive rates, contrasting negative or minimal CT_y treatments. However, compared CST, demonstrated higher equivalent yields comparable chickpea mainly due delayed germinations induced by lower temperatures plots. conclude that integrating site-specific characteristics, management practices, regional climate conditions into agriculture frameworks maximizes efficacy ensures productivity. These help optimize agricultural considering potential losses changes despite implementing CST.

Exploring the Influence of Land Use Types on Soil Properties at Arjo‐Dhidhessa Sugar Estate, Western Ethiopia

Applied and Environmental Soil Science, Journal Year: 2024, Volume and Issue: 2024(1)

This study examined the influence of land use types and soil depth on soil’s physicochemical properties in Sugar Estate Arjo‐Dhidhessa, western Ethiopia. aimed to provide baseline data for future investigations area by exploring significant quality indicators across various depths. Fifteen composite samples were collected from selected types, including fallow land, cropland, irrigated forest shrubland, at three different depths (0–30, 30–60, 60–90 cm). Particle size distribution; bulk density ( ρ b); total porosity (Tp); pH; organic matter; available texture phosphorus. The exchangeable acidity (EA), cation exchange capacity, bases (EBs) found be influenced changes depth. results revealed that (1.43 g/cm 2 ) is highest cropland subsurface, whereas lands tend have a relatively high clay content (67%), moisture (25.74%), Tp (54.28%). While pH was 5.17, varied 5.47 5.84. Compared with other uses, shrubland areas presented higher levels matter (SOM) (2.49%) nitrogen (TN) (0.126%). Forest SOM (2.45%), TN (0.126%), phosphorus (AvP) (1.36%), calcium (Ca 2+ (16.82 cmol/kg), had lowest amounts (5.22 mg/kg), Ca (3.97 magnesium (Mg (0.99 cmol/kg). In contrast, agricultural activities significantly reduce quality, as evidenced densities well lower nutrients, AvP EBs, primarily due erosion crop harvesting. To maintain improve levels, it essential adopt sustainable management practices contribute maintaining improving overall fertility.
