Soil scientists and agronomists at the Faculty of Agriculture and Plantation Management, Wayamba University of Sri Lanka (Makandura campus), have developed an innovative biochar-enriched organic fertilizer designed to protect plantation crops from severe dry spell degradation.

Manufactured through controlled low-oxygen pyrolysis of discarded coconut shells and agricultural crop residues, the biochar acts as a microscopic sponge within sandy soils. Comprehensive field trials conducted across Kurunegala and Makandura demonstrated that the amended biochar retains up to 40% more soil moisture while minimizing chemical nutrient leaching. University researchers noted that the circular agricultural technology offers a scalable, low-cost climate adaptation solution for plantation growers facing prolonged dry spells across Sri Lanka's intermediate climatic zones.
