The Advantages of Foliar Fertilization and Practical Tips to Improve Its Effectiveness
Foliar fertilization allows nutrients to enter the plant through the leaves and take part in the crop's metabolism and the synthesis of organic matter. Compared with soil fertilization, it has the following five advantages: (1) Rapid absorption. When urea is sprayed on apple and pineapple leaves, 50% can be absorbed after 1 to 4 hours; when urea is sprayed on the leaves of cucumber, broad bean, tomato and banana, 50% can also be absorbed after 1 to 6 hours. In contrast, urea applied to the soil generally takes 3 to 5 days to show results; (2) High fertilizer use efficiency. According to research, the use efficiency of foliar-sprayed boron fertilizer is about 8 times that of applying it as a base fertilizer; (3) It can avoid the fixation of fertilizers such as phosphorus, iron and zinc in the soil; (4) When the crop root system is under environmental stress (such as salt damage, water damage, drought, etc.), or when the crop has special nutritional requirements at a certain stage, it can replenish nutrients in time; (5) It can improve the quality of agricultural products.

Is it true that pothos absorbs formaldehyde? A full analysis of its effectiveness
Pothos can absorb formaldehyde. It can use formaldehyde for photosynthesis and also has a certain adsorption effect on formaldehyde. However, it cannot be used as the main method for removing formaldehyde, and is generally only used as a supplementary means. The best way to remove formaldehyde is still to open the windows for ventilation.
