ਭੁੱਲਕੇ ਵੀ ਪਰਾਲੀ ਨੂੰ ਕੌਡੀਆਂ ਦੇ ਮੁੱਲ ਨਾ ਚੁਕਾਓ Paddy stubble soil health relation ex-situ &in-situ

According to data from Punjab Agricultural University (PAU) and agricultural research across the Indo-Gangetic plains, 1 ton (tonne) of dry rice stubble/paddy straw contains approximately the following nutrient profile: 🌾 Macro and Secondary Nutrients (Per Ton) • Organic Carbon (C): ~400 kg • Potassium (K): 25 kg (Equivalent to around 41.6 kg of Muriate of Potash) • Nitrogen (N): 5.5 kg (Equivalent to around 12 kg of Urea) • Phosphorus (P): 2.3 kg (Equivalent to around 14.1 kg of Single Super Phosphate) • Sulphur (S): 1.2 kg 🧪 Micronutrients & Mineral Composition A single ton of rice residue also recycles crucial micronutrients back into the soil, including: • Silicon/Silica (Si): 40–70 kg • Iron (Fe): ~777 g • Manganese (Mn): ~745 g • Zinc (Zn): ~100 g 💡 PAU Fertilizer Savings Guideline Because of this rich nutrient profile, PAU explicitly highlights that burning stubble destroys over 90% of the Nitrogen and Sulphur, alongside 20-25% of the Phosphorus and Potassium. If you practice in-situ management (using machinery like the Happy Seeder or Smart Seeder to retain and incorporate residue into the soil) continuously for 3 years, PAU recommends that from the 4th year onward, you can safely reduce your chemical urea application by 20 kg per acre due to natural nutrient recycling. If you are planning your crop cycle, let me know which machinery you plan to use for management or what crop you intend to sow next so I can provide specific fertilizer adjustment advice. how bale making in rice field is dangerous for soil health Bale making in rice fields—also known as ex-situ straw removal—is widely adopted to prevent the severe air pollution caused by stubble burning. However, complete and continuous removal of rice straw from the field damages long-term soil health by stripping the land of its natural recycling mechanisms. While it is far less destructive than burning (which instantly kills microbes and vaporizes nutrients), mechanical baling poses several hidden risks to the soil ecosystem: 1. Severe Nutrient Depletion Rice straw is not just waste; it is highly rich in vital plant nutrients. When straw is baled and carried away off-field, the natural loop of nutrient recycling is completely broken. A single ton of rice straw contains roughly:
