One common myth is that ammonium bicarbonate can be applied on the surface or mixed with water. However, this fertilizer is highly prone to decomposition and volatilization, often referred to as "gas manure." Applying it superficially not only reduces its efficiency but also leads to significant ammonia loss when temperatures rise. Additionally, the fertilizer may stick to plant leaves and stems, causing burns—especially if applied early in the morning. If there's insufficient water, the fertilizer remains on the soil surface, increasing nitrogen loss through volatilization. To address this, ammonium bicarbonate should be applied deeper into the soil by digging trenches and covering it properly. If watering is inadequate after application, it's important to water promptly to improve efficiency. Studies show that deep application increases nutrient utilization by 10% to 30% and boosts crop yield by around 10%, which is about 8% more effective than surface watering. Another misunderstanding involves applying urea on the surface or flooding the field immediately after. Urea is an amide nitrogen fertilizer that needs to convert into ammonium carbonate in the soil before plants can absorb it. This conversion depends on the enzyme urease. If applied to the surface, especially on calcareous or alkaline soils, ammonia volatilization becomes a major issue. Also, if flooded right after application, urea may leach deep into the soil, reducing its effectiveness. The solution is to apply urea on dry land, either as a base or top dressing, ensuring it is placed in a moist layer of soil for better conversion. Watering should be sufficient, ideally 20–30 cubic meters per acre, and flood irrigation should be avoided. In paddy fields, apply urea before irrigation and avoid watering immediately afterward. Re-water every 3–5 days after the conversion process is complete. A third misconception is using diammonium phosphate with water. When applied with water, the fertilizer tends to stay on the surface, leading to nitrogen loss and poor phosphorus absorption by plant roots. To prevent this, diammonium phosphate should be applied in a shallow trench at a depth of about 10 cm and watered immediately after. This helps the fertilizer mix with the soil and improves its availability to plants. Another mistake is using superphosphate directly as seed fertilizer. Superphosphate contains free acid, which can corrode seeds over time and reduce germination rates. The correct approach is to apply superphosphate next to or below the seed, keeping it separated to avoid direct contact. This minimizes the risk of damage to the seeds. A fifth misunderstanding is using calcium magnesium phosphate as a top dressing. Since it dissolves slowly and is insoluble in water, it is not suitable for surface application. It works best as a base fertilizer, applied early in the season to allow for gradual dissolution. To maximize its benefits, it can be mixed with organic matter or composted before application. This enhances its availability and improves soil structure. Another common error is mixing human waste with wood ash for storage and later use. Wood ash is alkaline and accelerates ammonia loss when combined with human excreta. For example, mixing ash with urine in a 1:1.5 ratio for three days can lead to a 27.4% nitrogen loss, and up to 85.6% after three months of storage. The correct practice is to avoid mixing human waste and ash together. Instead, separate them and treat each properly before use. Finally, some people apply raw human urine directly to vegetables. This can introduce harmful bacteria and parasites, contaminating the crops and posing health risks to consumers. To safely use human urine as fertilizer, it must first be treated through methods like sealing, stacking, or disinfection. Only then should it be applied to crops to ensure safety and effectiveness.
The gas oven is a modern cooking device that combines efficient heating and easy operation. It uses clean gas as an energy source to heat ingredients quickly and evenly through a precisely controlled flame, and whether it is baking pizza, barbecue or baked bread, it can be easily harnessed to bring mouthwatering taste. Gas ovens are not only easy to operate and quickly preheat, but also energy efficient, making them ideal for modern kitchens and commercial dining venues.
When the Gas Pizza Oven is working, the gas flow is controlled by the gas valve. After the ignition device ignites the gas, the flame burns in the furnace to produce high temperature. Heat is transferred to the pizza through the furnace wall, which heats it evenly and gradually RIPS it. Gas pizza ovens are usually equipped with temperature control systems that can precisely adjust the baking temperature to ensure the baking effect of the pizza.
High efficiency: Gas Pizza Oven heating speed, can reach the required baking temperature in a short time, improve baking efficiency.
