In the delicate balance of soil chemistry, Soil Salinity is perhaps the most visible indicator of land degradation. It is a process where water-soluble salts accumulate in the soil layers to a level that impacts plant growth and environmental health. While salinity is a natural phenomenon in some coastal regions, it is increasingly becoming a man-made crisis in the dry zones of Sri Lanka, often driven by mismanagement of our most precious resources: soil and water. For the mo

To understand soil productivity, one must look past the physical texture of the earth and into its chemical "engine room." Soil pH is not merely a number on a lab report; it is a measure of the chemical potential energy that dictates the solubility of every mineral necessary for plant life. In the diverse landscapes of Sri Lanka—from the ferruginous soils of the dry zone to the highly leached, acidic podsols of the wet zone—pH management is the primary lever for yield optimiz

In the quiet of a mid-country morning, a tomato farmer might walk through a field of vibrant, green plants, only to find a few looking strangely "tired." By sunset, those same plants are often completely limp. This isn't just dehydration; it’s the work of Bacterial Wilt, caused by the formidable soil-borne pathogen Ralstonia solanacearum. To many, it is known as the "cancer of the soil." It is a devastating disease because, unlike many fungal infections that give you weeks to

The agricultural sector is currently navigating an era of unprecedented atmospheric volatility. For the modern grower, "Climate Variability" is no longer a distant environmental concern—it is a daily operational reality that dictates profit margins and food security. Unlike the slow, steady shift of "Climate Change," climate variability refers to the shorter-term fluctuations in weather patterns—the year-to-year swings that make one season a drought and the next a flood. To t

In today’s fast changing world of agriculture, making the right decisions at the right time can make a big difference.
