Cereals

 

Fertilise correctly – harvest quality

Besides the use of cereals for food and feed, the importance as a renewable energy resource for the production of biofuels is ever increasing. The quality demands of cereals vary according to the destined end use but a large proportion of these quality criteria can be positively influenced by judicious use of fertilisers. It is important therefore not only to optimize nitrogen supply but also to adjust the supply of magnesium sulphur and phosphorous as well as that of trace elements.

 

The quality of cereals is defined by the required end use. Depending on the end-use the following criteria are significant:

Potassium and phosphorous are essential for yield

The grain yield of cereal is the sum total of crop density (Number of ear bearing shoots per square meter) and the yield of each ear (number of grains per ear and their thousand grain weight). By tailoring a specifc nutrient management program to the individual crop, these quality parameters can be successfully influenced.

Yield and quality insurance using magnesium and sulphur

 

The nutrient combination of potassium and magnesium (as well as sulphur) in Korn-Kali results in significantly higher yields and an increased efficiency of nitrogen fertilisation in comparison to muriate of potash (straight potassium chloride) which contains no magnesium or sulphur.

Fertiliser recommendations

When planning a fertiliser program for cereals, both the soil fertility and condition and also the required quality of the end product must be taken into account

 

Recommendations for soil applications

 

Recommendations for foliar applications

In the case of an additional requirement of trace elements, approx. 20-30 kg ha-1 EPSO Combitop (total amount) can be applied: In autumn 10-15 kg ha-1 from EC 15 and in spring twice 10-15 kg ha-1 from the start of the main spring growth period.
