Straw fertilization to prevent soil disorders
Compared to open-field farming, greenhouse vegetable cultivation requires more precise and careful management of fertilizers. Improper application can lead to serious issues such as soil salinization, acidification, and imbalanced nutrient levels. To address these challenges and maintain healthy soil conditions in greenhouse environments, the following practices are recommended: 1. The use of organic fertilizers, especially coarse manure with high fiber content, provides a well-rounded source of nutrients for vegetables. This helps improve the soil's ability to buffer nutrient fluctuations, prevents salt buildup, and slows down the process of soil salinization. 2. After harvest, deep plowing should be performed to mix the topsoil, which tends to accumulate salts, with the lower layers that have less salt. This practice effectively reduces the harmful effects of salt accumulation on plant growth. 3. Removing plastic mulch and replacing it with fresh soil, followed by flooding the surface with water, helps leach out accumulated salts from the soil. This technique is particularly effective in reducing salinity in the root zone. 4. Promoting balanced or formula fertilization is essential. Based on soil test results, crop requirements, and nutrient demand patterns, applying the right amounts of nitrogen, phosphorus, potassium, and micronutrients ensures a better nutrient balance while minimizing soil degradation. 5. Apply basal fertilizer at a deeper level during plowing, avoiding excessive salt accumulation in the topsoil. For top-dressing, apply it sparingly and only when necessary to prevent over-fertilization. 6. Encourage root-side fertilization, where nutrients are applied directly to the root zone. This method not only minimizes the risk of soil salinization and acidification but also delivers nutrients more efficiently to the plants, promoting healthier growth. By implementing these strategies, greenhouse farmers can maintain soil fertility, reduce environmental stress, and ensure sustainable vegetable production. These techniques are not only practical but also environmentally friendly, supporting long-term agricultural productivity. Youth Biotech CO,. Ltd. , https://www.youtherb.com
