The agriculture grade zinc sulphate, purchased from Rech Chemical Co. Ltd, could be applied in basal fertilization and topdressing, spraying, soaking seed, and seed dressing. In order to help you to apply zinc fertilizer more scientifically and reasonably, Rech chemical now share a solution of zinc spraying supplementation for rice. And the simple fertilization technology is as follows:
1. The Spraying Period: It’s preferred to spray zinc sulfate in seedling stage, presumably 10-15 days before rice transplanting; in wide fields, it’s better to spray when rice tiller.
2. Spraying Time: before 10 AM in the morning or after 6 PM; if rain comes after spraying, you have to spray again.
3. The Dosage and Concentration: fertilize zinc sulphate 0.3 kg for each 1/15 acre. You could spray zinc sulfate 0.6% solution on the leaves, 50 ~ 60 kilograms for each 1/15 acre.
