PAU: Thin layer of deposit not necessarily bad

Punjab Agriculture University (PAU) Vice-Chancellor Satbir Singh Gosal on Friday urged farmers to consult Krishi Vigyan Kendras before removing silt from their fields, saying layer up to five inches could be mixed with soil to improve productivity.

He, however, said the complete removal was needed in cases where the fields were thickly covered with silt.

The advice comes as focus has now shifted to the clearing of silt from farmlands, a major challenge for cash-strapped farmers as floodwaters recede.

Dr Gosal said silt deposits up to five inches could be naturally mixed with the soil. “Sand and clay must be removed carefully, but red soil, if present, can actually benefit the field,” he stressed.

The Vice-Chancellor urged farmers to consult their nearest Krishi Vigyan Kendras (KVKs) before taking any action. “We have KVKs in every district and scientists are available to guide farmers based on local conditions,” he added.

To assist farmers in assessing the impact on soil health, the university has announced free soil testing services. Samples will be collected by the KVKs and sent to the university for the analysis.

Based on the results, tailored recommendations will be provided to help restore fertility and guide nutrient management. “The sowing window for the next crop falls between October 15 and November 15, and we are hopeful that the fields will be cleared of flood-deposited silt in time,” said Dr Gosal.

Dr Manjt Singh, head of the Farm Machinery and Engineering Department at PAU, added that farmers facing large-scale deposits could consider selling the excess silt.

“Mud loaders and trailers can be used for removal. If the mud has hardened, reversible ploughs can help loosen it.

After ploughing, a leveller should be used to create a smooth, uniform surface for planting,” he said.
