Theammonium sulfateor ammonium sulfateit is a salt produced by direct reaction between sulfuric acid and ammonia. This compound has several uses, the most common being asfertilizeragricultural.
Ammonium sulfate: formula and production
The chemical formula of the ammonium sulfate or ammonium tetraoxydosulfate is: (NH4)2SO4
For those who do not chew chemicals, let's remember the symbols of the elements involved in the composition:
- N - nitrogen
- H - hydrogen
- S - sulfur
- O - oxygen
The reaction between sulfuric acid and ammonia that leads to the production ofammonium sulfateis described as follows:
H.2SO4 + 2 NH2-> (NH4)2SO4
The two reactants, sulfuric acid (in liquid form) and ammonia (in gaseous form) give life to a molecule ofammonium sulfatein solid form.
Ammonium sulphate: fertilizer
In agriculture, theammonium sulfateis used asnitrogen fertilizer. It is mainly used in alkaline and calcareous soils. The purpose? Add nitrogen and lower the soil pH reaction.
In fact, in the soil, the ammonium ion is released and forms a small amount ofacidlowering the pH of the soil.
Compared toammonium nitrate(also counted among nitrogen fertilizers), ammonium sulphate provides a smaller quantity of nitrogen for the same weight used. Theammonium sulfatehas a nitrogen content of 21.33%.
Always inagriculture, theammonium sulfateit is used as an adjuvant for water-soluble pesticides, for herbicides and fungicides.
Theammonium sulphate for plantsit settles easily in the ground, gradually releasing nitrogen which is then absorbed by plants. It can be counted among thenitrogen fertilizersslow release.
For an optimal result, following the administration ofammonium sulfateit is advisable to irrigate the soil. It is important to water the soil only after having distributed the fertilizer and never before. Indeed, for fertilization it is useful to choose a relatively dry day because the fertilizer should not be put on moist soil.
Theammonium sulfatenot only adds nitrogen to plants but also releases sulfur. The gradual release of nitrogen allows for better production. For this reason, suchfertilizerit is suitable for fruit and vegetable plants. The leaves and fruits, thanks to the contribution of nitrogen, have more intense colors, larger sizes (vegetables and fruits will be larger) and the plant will become more resistant and robust.
Ammonium sulphate to acidify the soil
Who wondershow to lower the pH of the soilit can undoubtedly exploit the acidifying power of ammonium sulfate.
The ammonium sulfate, compared to many othersfertilizers, has an advantage that is useful for various horticultural, fruit and ornamental crops. Ammonium sulphate has the ability to lower the pH of the soil: many plants are able to better absorb nutrients from the soil when the pH is lower, in addition, the decomposition of organic substances naturally present in the soil increases in speed so as to give space for humus production.
Ammonium Sulfate: Benefits
The ammonium sulfate forfertilize the soil it is marketed in the form of granules, crystals or, more rarely, in liquid form. Based on the product formulation it is possible to estimate the quantities to be used.
This fertilizer should be used during vegetative growth or in preliminary soil tillage. The benefits you bring to the ground only:
- Nourishing action, releasing nitrogen slowly (slow release nitrogen fertilizer)
- Acidifying function, excellent for promoting the natural formation of humus and making the soil fertile
- Long-term acidifying function can be used to correct calcareous soils and treatment of alkaline soils
- Anti-parasitic action
How to use? Just spread it on the ground by broadcasting (by hand) or with a fertilizer spreader in order to obtain a homogeneous distribution of the product.
For the preparation of the soil, before sowing, the fertilizer ammonium sulfateit must be buried by digging more or less deep, according to the quantity of hard clods present in the ground.
Recommended dose and where to buy it
The recommended dose is 5 - 8 kg per 150 sqm of land, however, as some producers sometimes mixammonium sulfatewith other compounds, it is important to read the directions on the label or make sure you buy a fertilizer based exclusively onammonium sulfate.
We advise against using liquid preparations for two reasons:
- They cost more and have a lower yield
- They are more difficult to apply because if a few drops land on the leaves and fruits, it risks burning them
Where to buy it?
Ammonium sulphate is easy to find in agricultural consortia or well-stocked garden centers. It is also possible to buy it by taking advantage of the online shopping where there is no shortage of great offers. On Amazon, for example, a 5 kg bag ofammonium sulfategranular can be bought at a price of 11 euros with free shipping.
