The use of biochar reduces soil erosion levels and increases moisture reserves — results of experiments

The average soil erosion rates in Mediterranean vineyards are estimated at 9.3 t/ha/year, making the need for a practical, long-term solution critically important. Portuguese scientists conducted a study aimed at testing the effectiveness of biochar application, reports AgroPages. It is noted that the European viticulture sector, especially in the Mediterranean region, faces a serious threat of water erosion. The combination of hilly terrain, soil cultivation without cover, and intense short-duration rainfall, which often occurs after prolonged droughts, accelerates soil loss, threatening the long-term health and productivity of vineyards. Researchers conducted an 18-month lysimeter experiment in an outdoor setting on a sloping sandy loam soil typical of Portuguese vineyards. The results were immediately convincing. Throughout the monitoring period, the application of biochar (biochar) significantly reduced the rate of vineyard soil erosion compared to untreated control soil. ...
