1. It was used as basal fertilizer. When ammonium sulfate is used as basal fertilizer, soil should be deeply applied to facilitate the absorption of crops.
2. As topdressing. This is the most suitable method of application. According to different soil types to determine the amount of ammonium sulfate topdressing. For soil with poor water and fertilizer conservation performance, it is necessary to apply it by stages, and the dosage should not be too much for each time; For soil with good water and fertilizer conservation performance, the dosage can be appropriately increased. How much soil moisture also has a greater impact on fertilizer efficiency, especially in dry land, the application of ammonium sulfate must pay attention to timely watering. As for the paddy field as topdressing, should be the first drainage to dry, and should pay attention to the combination of The Rake at the same time. In addition, there are also significant differences in the application of ammonium sulfate in different crops. For example, when used in fruit trees, it can be applied by furrow, ring or hole.
3. More suitable for seed fertilizer. Because ammonium sulfate had no adverse effect on seed germination.
1. It should not be contacted or mixed with other alkaline fertilizers or alkaline substances to prevent reducing fertilizer efficiency.
2. It is not appropriate to apply ammonium sulfate on the same piece of farmland for a long time, otherwise the soil will become acidic and cause hardening. If it is necessary to apply, it can be appropriate with the application of some lime or organic fertilizer. However, attention must be paid not to mix with lime to prevent decomposition of ammonium sulfate and nitrogen loss. In general, the cooperation of the two is separated by 3 to 5 days.
3. Not suitable for application on acid soil.
It is packed in polypropylene woven bags lined with plastic film bags (or coated with plastic film). Handle with care during transportation to prevent the bag from being broken. When storing outdoors, pay attention to moisture-proof and rain-proof, avoid storage at high temperature, and do not store it with alkaline substances. Water can be used in case of fire.
