More energy for your corn – DOMOGRAN® ammonium sulphate fertiliser

Do you want to maximise the potential of your corn crop? Then you should apply DOMOGRAN® in combination with organic manure via a direct fertilisation seed drill. Owing to its high ammonium nitrogen and sulphur sulphate content, this coarse crystalline fertiliser provides excellent early development and enhanced root growth in corn. Applying DOMOGRAN® also promotes stress resistance to drought and late frosts during the growth phase. The coarse crystalline fertiliser increases the availability of phosphates and micronutrients such as boron and zinc, which are contained in the soil. Not only does this enable you to achieve a higher yield, but you will also increase the energy density in the corn plant. DOMOGRAN® supports your corn crop and has both a direct and an indirect positive effect on the complex processes that take place during the growth phase.

Benefits and effects of ammonium sulphate used on corn

Increase in energy density and yield 

DOMOGRAN® provides sulphur sulphate and ammonium nitrogen and indirectly influences the release of micronutrients by reducing the pH level of the soil. In addition, phosphate and boron are mobilised. As a component in ATP, phosphate has the important function of being an energy carrier within the plant. The combined properties of ammonium sulphate make high energy content and a high yield possible for your corn crop.

Preventing sulphur deficiency in corn 

At the start of the growth phase, the amount of available sulphur is not usually sufficient for corn. Due to the microbial conversion processes of previous crops, usable sulphur is immobilised and therefore not available for corn to use.  Furthermore, long-term organic fertilisation only provides enough available sulphur for plants in June. By applying a dosage of DOMOGRAN® you are providing your corn crop with sulphur sulphate from the beginning and ensuring the perfect starting conditions for your plants as they start to grow.


- Annual rainfall 760 mm
- Fine, sandy clay
- soil value 65-80
- pH 6,5
- Phosphorus content class C (2016)
- Phosphorus content class A (2017)

Indirectly promoting length growth 

The acidifying effect of ammonium sulphate fertiliser leads to an increased availability of micronutrients contained in the soil. Among them are manganese and zinc, which have a positive effect on the growth of the corn stalk. A deficiency in both elements leads to restricted growth, which is why sufficient amounts of each must be made available to the plant during its growth phase. DOMOGRAN® activates the previously untapped nutritional potential of the soil, effectively preventing your corn plants from under-developing in the early stages.

Increased energy density and higher yield

Practical tips and usage of DOMOGRAN® 45 

Nitrogen requirements of corn 

During the first eight weeks, corn crops need a dose of 20 - 40 kg/hectare of nitrogen, depending on the type of soil. This is equivalent to an application of 100 - 200 kg of DOMOGRAN®.

Usage in combination with phosphate fertilisers 

In some areas with high calcium content, phosphate is extremely tightly bound within the soil and not available to plants. In these areas, it is recommended to use ammonium sulphate in combination with diammonium phosphate (DAP). 

Suitability and spreading 

DOMOGRAN® is generally recommended for forage, grain and biomass corn crops. The coarse crystalline ammonium sulphate can either be applied directly or spread over the surface. It should be applied either before tillage or after drilling.


Did you know? Corn: Europe's all-rounder crop from Mexico 

Established in Europe as a poor man’s supper 

The forerunners of the corn varieties we know today originally came from Mexico. A sweet grass (Poaceae) plant, corn had already been used as a source of nutrition there for millennia. The plant was brought over to Europe by the Spanish, just like potatoes. The cultivated crop then spread rapidly among the southern European countries right down to the Middle East. In contrast to other field crops in the Mediterranean area, corn was easy to manage, high-yielding and ready for harvest in the summer. Above all, poorer citizens benefited from this new agricultural opportunity and used it excessively to fight against relentless poverty. Unfortunately, with only corn as a primary source of nutrition, they became deficient in niacin (vitamin B3), which led to serious long-term consequences.


Deficiency in this vitamin causes pellagra, a disease with symptoms such as diarrhoea, skin disease, dementia and in serious cases, even death. Nowadays, pellagra is no longer an issue in Europe and thanks to the cultivation of more robust and cold-resistant varieties, the sweet grass is now established in the north of Europe as well.  

A popular crop that is both energy-rich and flexible 

Corn is the ultimate all-purpose crop. Not only does this crop produce food for humans and animals alike, it can also be used to produce bioethanol and is commonly utilised as an energy carrier in biogas plants. Corn is even suitable for producing biodegradable plastics for packaging, for example. As a C4 plant, corn is capable of converting carbon more effectively. Corn can photosynthesise and generate biomass even at high temperatures and with closed stomata. In this respect, C4 plants have an advantage over C3 plants, such as wheat. Researchers have been attempting to transfer this property to other cultivated plants for a long time, without any significant breakthroughs so far.
