Harmonizing models and measurements: Assessing soil erosion through RUSLE model.

Soil erosion poses significant ecological and socioeconomic challenges, driven by factors such as inappropriate land use, extreme rainfall events, deforestation, farming methods, and climate change. This study focuses on the Kozhikode district in Kerala, South India, which has seen increased vulnerability to soil erosion due to its unique geographical characteristics, increase in extreme events, and recent land use trends. The research employs RUSLE (Revised Universal Soil Loss Equation), considering multiple contributing factors such as rainfall erosivity (R), slope length and steepness (LS), cover management (C), conservation practices (P), and soil erodibility (K).

Comparative analysis of soil organic carbon and soil properties in landscapes of Kerala: insights from the Western Ghats of India.

Soil organic carbon (SOC) is known to vary among different ecosystems and soilscapes, yet the degree of variation remains uncertain. Comparing SOC levels in undisturbed ecosystems like forests with those in gradually altered ecosystems can provide valuable insights into the impact of land use on carbon dynamics. This study aimed to evaluate the effects of different land uses on soil fertility parameters in the tropical region of Kerala, focusing on forests as well as cultivated agricultural landscape such as coconut, pepper, tapioca, acacia plantations, and mixed home garden cropping systems.

Understanding the leaf rolling of paddy and exploring its management options under aerobic rice.

Rice is a staple food in the diets of more than half of the world's population. With India's irregular rainfall patterns and continual environmental anomalies, particularly in Kerala, the identification of climate-smart management practices which can withstand drought is critical. In this context, atrial was conducted in the experimental plots to evolve effective water and nutrient management practices under aerobic rice in lateritic soils of Kerala.

Distribution of geochemical forms and bioavailability of phosphorus in the surface sediments of Beypore Estuary, southwestern coast of India.

Nutrient management in shallow transitional aquatic systems is very complex due to the sediment-water exchange, especially for phosphorus. The present study tries to get an in-depth understanding of the distribution of geochemical forms of phosphorus in the surface sediments of Beypore Estuary, a tropical estuarine system in southwest India, which has been subjected to immense climate change in recent times. Total phosphorus in the sediments was found to be abysmally lower (76.
