The direct use of ammonium sulfate in agriculture will increase significantly
Ammonium sulfate made of compound nitrogen fertilizer or extruded pellets, although the total nutrient is lower than urea, but because it contains the element of sulfur, its actual use is much better than the equivalent amount of nitrogen urea, coupled with a significant drop in price, therefore, the direct use of the agricultural market will increase significantly, forming a substitute for urea. Compared with urea, ammonium nitrogen of ammonium sulfate is less volatile and more easily fixed by soil, and ammonium nitrogen can be directly absorbed by crops, and the utilization rate is higher than urea, so it is worth promoting.
How many days does ammonium sulfate topdressing take effect ? What kind of fertilizer is it?
Ammonium sulfate is an excellent nitrogen fertilizer, easily dissolved in water, acidic, can be used as a base fertilizer, additional fertilizer, seed fertilizer; after the application of ammonium sulfate, it takes about 3-7 days to take effect, and the duration of the fertilizer effect remains at about 50-60 days; after the application can promote into the growth of crop branches and leaves, improve the yield and quality of fruit, and enhance the crop's resistance to adversity. Ammonium carbon takes effect on the same day, and the fertilizer effect lasts about 15 days; ammonium chloride takes 3 days to take effect, and the fertilizer effect lasts about 25 days; urea takes 7 days to take effect, and the fertilizer effect lasts about 45 days; long-lasting urea takes 7 days to take effect, and the fertilizer effect lasts about 110-130 days; compound fertilizer needs 10 days to take effect, and the fertilizer effect lasts about 90 days; biological fertilizer takes 30 days to take effect, and the fertilizer effect lasts about 30 days. It takes 30 days to take effect and the duration of fertilizer effect is 6-8 months.
What are the uses of ammonium sulfate？
Base fertilizer: When ammonium sulfate is used as base fertilizer, it needs to be buried deeply and then covered with soil on top of the fertilizer, which is beneficial to crop absorption.
Seed fertilizer: When using, you need to control the amount and should not use too much. Generally, use 5kg of ammonium sulfate fertilizer mixed with 25-50kg of organic fertilizer or fertilized soil per mu of land; when planting rice seedlings, you can use 2.5-5kg of ammonium sulfate fertilizer mixed with organic fertilizer and calcium superphosphate per mu of land, and then use it to dip the roots of rice seedlings after making a thin mud.
Additional fertilizer: ammonium sulfate is more suitable for use as an additional fertilizer, generally 15-20 kg of ammonium sulfate fertilizer is applied per mu; if it is used in dry land, attention should be paid to watering when fertilizer is applied, if it is used in paddy fields, the water in the field needs to be drained first, combined with plowing and harrowing at the same time; for crop fields with poor water and fertilizer retention capacity, fertilizer should be applied in several times, and the amount of fertilizer each time should not be too large.
