Advantage:

Physical and chemical properties are safer

suitable for all kinds of soil and crops

Transformation and utilization of beneficial and effective elements in soil

Can be used as base fertilizer, topdressing and seed fertilizer

APPLICATION:

1. Deep application of base fertilizer: combine with ploughing, plough while applying, and then fine leveling.

2. Bottom application of seed fertilizer: when the soil moisture is good, use the seed fertilizer seeder to concentrate on the bottom of the seeds or the lower side of the seeds. Ammonium sulfate nitrogen fertilizer can also be used as seed fertilizer together with decomposed organic fertilizer and phosphate fertilizer, but the seed fertilizer should not be too close to the seeds to avoid burning the seeds.

3. Top dressing ditch or hole application: ammonium bicarbonate, ammonia and urea should be covered with soil by ditch or hole application, and nitrogen fertilizer should be applied into the soil layer below 5~10 cm with hoe fertilizer applicator, ammonia water columbine, liquid fertilizer deep applicator, etc., and attention should be paid to uniform application. Ditch or hole application can improve fertilizer efficiency by about 30% than surface application.

Caution:

1. Do not use red ammonium sulfate in rice fields

2. Ammonium sulfate is an acid fertilizer, which will increase the acidity of the soil. Therefore, in acidic soil environment, attention should be paid to the use of alkaline fertilizers, such as plant ash, phosphate rock powder, calcium magnesium phosphate fertilizer, etc. In neutral and alkaline soil, in order to prevent the combination of calcium and sulfate to form insoluble calcium sulfate, resulting in soil hardening, it should be used together with organic fertilizer.

Storage:

1. Ammonium sulfate should be stored in a cool and ventilated warehouse.

2. Keep away from heat sources, store separately from acids and alkalis, and do not mix storage and transportation.

3. The storage area should have suitable containers to contain ammonium sulfate, and resolutely prevent leakage during transportation.

Precautions for transportation:

1. Red Ammonium sulfate shall be tightly packed before logistics transportation, and the packaging container shall not leak, collapse, fall or be damaged during transportation.

2. During transportation, it shall be protected from sunshine, rain and high temperature.

3. The delivered vehicles should be cleaned up in time and transported carefully.
