Organic Carbon particles mainly decompose organic matter in the soil, creating an ideal environment for microorganisms to grow. From there, the plants can develop healthy roots and absorb nutrients well. Naturally, the plants become healthier, more resistant to diseases, sprout and grow well, bringing high economic efficiency to the organic farming model.<\/p><p>Mr. Xuan&#8217;s experience is proof that choosing an effective and sustainable soil improvement solution is a key factor to improve the productivity and quality of durian gardens, especially in the context of climate change and increasingly degraded land. The application of Organic Carbon technology, through the product Nema2, not only solves the problem of acid sulfate contamination but also contributes to building a healthy and sustainable soil ecosystem, towards a high-quality organic agriculture.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Durian cultivation, especially in the Mekong Delta provinces, always brings great economic potential.
