Abstract
The currents study aims to showcase
comparative soil quality of six different regions of Karauli, including
Panchana dam (Site 1), Rangwana ka talab (Site 2), Needar Dam (Site 3), Jaggar
dam (Site 4), Sagar (Site 5) and Kalisil dam (Site 6) during summer season
(March-June), monsoon season (July-October) and Winter season (November-February).
pH showed significant seasonal fluctuations, ranging from 7.30–8.12, with the
highest values in summer and the lowest in winter. EC varied between 0.27–0.56
dS/m, recording maximum concentrations during summer due to salt accumulation and
minimum values during winter and rainy seasons. Organic content differed
substantially across seasons, with the lowest levels in summer (0.13–0.58%) and
highest levels in winter (0.18–0.75%), reflecting the influence of temperature
and moisture on microbial decomposition. Macronutrients demonstrated clear
seasonal trends: phosphorus varied from 27–58 kg/ha, sulphur from 7–16 kg/ha,
and potassium from 265–380 kg/ha, with all three nutrients showing maximum
availability in winter and minimum in summer. Similarly, micronutrient
concentrations displayed strong seasonal dependence, with Zn (0.24–0.58 ppm),
Fe (4.20–6.50 ppm), Cu (0.20–0.70 ppm), and Mn (2.60–4.35 ppm) peaking during
winter when cooler, moist conditions enhanced solubility and nutrient mobility.
Overall, the findings demonstrate that soil fertility parameters follow the
distinct trend winter > rainy > summer, highlighting the substantial
influence of seasonal environmental conditions on nutrient availability. These
results offer valuable insights for optimizing nutrient management strategies
and improving crop productivity in semi-arid agricultural systems.
