Sodium Nitrophenolates+Urea: a Quick Remedy for Yellowing Leaves in 3 Days
This combination of sodium nitrophenolates and urea works wonders for both seedlings and mature plants. In just 3 days, it can turn yellow leaves green and thin leaves thick.
I. Base Fertilizer Mixing: "Feeding and Awakening" the Root System, Seedlings Stand Tall in 3 Days
When applying base fertilizer to crops, the most easily overlooked problem is "unawakened roots"—the fertilizer is applied, but the seedlings' roots lack the strength to absorb it, resulting in yellow and thin leaves. At this point, you need to add something to the base fertilizer.
Whether you use 40 kg of urea or 40 kg of NPK compound fertilizer, first spread the fertilizer on a plastic sheet, then sprinkle 5-6 grams of 98% sodium nitrophenolates raw material on top—this small amount is a "root awakener"! Then, use a shovel to mix it evenly like flour, ensuring every grain of fertilizer is coated with the raw material, before burying it in the furrows.
II. Drip Irrigation and Fertigation: A "Savior" During the Fruiting Stage, Preventing Premature Aging and Promoting Larger Fruit Size
What's the biggest fear when crops are fruiting? The plants collapsing from exhaustion! The fruit needs nutrients, but if the plant ages prematurely, leaves turn yellow and fall off, and the fruit either stops growing or becomes small even when ripe. At this time, fertigation with "sodium nitrophenolate + urea" is effective.
Use 6-10 grams of 98% sodium nitrophenolate technical grade mixed with 15-20 kg of urea. First, dissolve the technical grade in warm water—remember to use warm water; this ensures faster dissolution and maintains efficacy. Then, dissolve the urea as well. Mix the two solutions in the fertigation container, fill with water, stir well, and pour the solution down the roots. For drip irrigation, simply pour it into the drip irrigation tape.
III. Foliar Spraying: Quick Rescue for Yellowing Leaves, Thicker Tree Leaves
If the leaves are already yellow and you want to see results quickly, foliar spraying is essential—like giving the crop an oral liquid. Nutrients are directly absorbed by the leaves. This method works for both vegetables and fruit trees.
Formula: 1.8% Sodium Nitrophenolates aqueous solution, diluted 3000-4000 times (1 ml of solution to 3-4 liters of water); plus urea, diluted 300-400 times (100 grams of urea to 30-40 liters of water). Mix the two solutions together, put them in a sprayer, and spray both sides of the leaves, especially the yellowing and thinning leaves, spraying them more thoroughly.
This method not only provides quick relief but also promotes faster nutrient transfer from the leaves, resulting in better fruit growth.
