BÓN ĐẠM URÊ NGÀY NẮNG: VÌ SAO CÀNG BÓN CÀNG MẤT TIỀN?

Applying a bag of urea fertilizer to your garden may only result in the plants absorbing a portion. Where does the rest go? After being spread on the ground, urea reacts with the enzyme urease and moisture, rapidly hydrolyzing to form ammonia. This process increases the pH around the fertilizer granules, causing some of the nitrogen to convert into ammonia gas (NH₃) and evaporate into the air. The risk of loss is even greater when the ground is hot, humid, contains a lot of organic matter, has a high pH, ​​and the fertilizer remains on the surface for a long time without being watered or buried. Under unfavorable conditions, the amount of nitrogen lost can reach tens of percent, meaning the money spent on fertilizer is "evaporating" before the roots have a chance to absorb it. This video will help you understand: Why can urea evaporate after application? What conditions cause the most significant nitrogen loss? Why shouldn't you apply urea when the soil is hot and leave it on the surface? When is the best time to fertilize and how should it be handled to retain nitrogen for the plants? Farmers should prioritize fertilizing when the soil has suitable moisture, then water thoroughly or lightly cover the fertilizer to help it penetrate the soil. Avoid spreading fertilizer on the surface of hot soil and then leaving it for many days without rain or watering. #Fertilizer #Urea #AgriculturalTechniques #CropCare #FarmerKnowledge
