How to use ammonium sulfate:

‌Base fertilizer: Ammonium sulfate can be used as base fertilizer, but it needs to be deeply applied and covered with soil to facilitate crop absorption. Suitable for crops such as wheat, corn, cotton, sweet potato, hemp, cereals, fruit trees, vegetables, etc. ‌
‌Topdressing: This is the most suitable application method. Determine the amount of ammonium sulfate for topdressing according to different soil types. For soils with poor water and fertilizer retention performance, topdressing should be applied in stages, and the amount should not be too much each time; for soils with good water and fertilizer retention performance, the amount can be appropriately more each time. Pay attention to timely watering when applying, especially when applying in dry land ‌
‌As seed fertilizer: Ammonium sulfate has no adverse effects on seed germination and is suitable for seed fertilizer ‌
‌Precautions for ammonium sulfate: ‌Avoid contact or mixed application with other alkaline fertilizers or alkaline substances to prevent reduced fertilizer efficiency .
‌It is not advisable to apply ammonium sulfate for a long time on the same piece of arable land, otherwise the soil will become acidic and cause compaction. If it is necessary to apply, some lime or organic fertilizer can be applied in appropriate amounts, but it must be noted that ammonium sulfate and lime cannot be mixed to prevent the decomposition of ammonium sulfate and nitrogen loss. ‌

1. ‌Pay attention to soil moisture when applying, especially when applying in dry land, pay attention to timely watering. ‌
1. ‌It is not advisable to fertilize seedlings too early. Wait until the seedlings adapt to the environment before starting to fertilize in small amounts to avoid damaging the root system. ‌
