Leaf mesophyll turns yellow but veins stay green, showing netted veins. In severe cases, the whole leaf withers, turns white or falls off. Fruit trees and ornamental plants on calcareous soils in northern China are prone to chlorosis. Dosage: (1) Foliar spray: Dilute with water by 800–1200 times, spray evenly on leaves, apply 2–3 times at intervals of 7–10 days. (2) Soil basal or topdressing: 1000–3000 grams per mu for general crops, applied after mixing with organic fertilizer. (3) Injection method: For fruit trees, use 10 mL of 0.1% ferrous sulfate solution (diluted 1000 times). Insert the needle into the trunk, hang the infusion bottle on the tree for slow absorption. This method acts quickly, with visible effects in 3 days. (4) Direct soil application of iron fertilizer easily converts to high-valent iron compounds and becomes ineffective. Therefore, mixing ferrous sulfate with 10–20 times of organic fertilizer as base fertilizer gives better results. Foliar application of 0.2%–0.5% ferrous sulfate aqueous solution is better than soil application. The safe concentration of ferrous sulfate is 0.2%–0.3%.
