Punjab's flooded farmlands face nutrient shifts ahead of rabi season

A new study by Punjab Agricultural University (PAU) has uncovered significant changes in Punjab's farmlands after recent flooding. The research highlights shifts in soil composition, nutrition levels, and potential challenges for the upcoming rabi season. Farmers are now receiving tailored advice to restore soil health before planting begins.

The floods left behind a mix of effects on Punjab's soils. While some areas gained beneficial minerals, others faced nutrient imbalances and compacted layers. Sediment deposits varied widely—some fields had up to a metre-thick layer, while others showed only light coverage.

Testing revealed that eight of the 22 surveyed districts now struggle with manganese deficiency, particularly in paddy, wheat, and maize crops. Phosphorus and potassium levels fluctuated, and iron concentrations rose in certain spots. Soils remained mostly alkaline, with no major salinity risks, but organic carbon content increased, averaging over 0.75 per cent.

PAU has sent teams across districts to analyse soil samples and provide localised solutions. They advise farmers to avoid stubble burning and instead mix straw into the soil to improve nutrition. Deep tillage is recommended to break up hardpans formed by sediment pressure, ensuring better water drainage and root growth.

For the rabi season, PAU suggests a 2 per cent urea spray and close monitoring of manganese levels in wheat and barseem. These steps aim to counter the disruptions caused by flooding and support crop recovery.

The study offers farmers clear guidance to address soil changes before the rabi planting. By adjusting nutrient management and adopting soil-friendly practices, growers can mitigate flood impacts. PAU's recommendations focus on restoring balance and ensuring productive harvests in the months ahead.
