A mixture of regular sugar and commercially available nitrogen fertilizers helps wheat produce more protein, among other things. But the timing of application is very important.
Advantages
Our Land, Bavarian Radio Channel In your YouTube video Two farmers talk about their experience with sugar and nitrogen spraying. We are talking about several years of experience, during which they tried to dissolve 5 kg of sugar and 5 kg of nitrogen fertilizers in 150 liters of water per hectare. Spraying with the mixture has a positive effect on the hectoliter weight and protein production of wheat, and the treatment can lead to an additional yield of up to 350 kg. The consultant assumes an additional amount of about 80 euros per hectare of treatment at a cost of about 30 euros per hectare. Another advantage is that wheat can better tolerate drought stress as a result of the mixture. At the same time, the timing of the treatment is especially important. Wheat should be treated 7-14 days after flowering, otherwise the spraying will not have the desired effect.
Challenges and concerns
However, applying a mixture of fertilizers, sugar and nitrogen is not only beneficial, but can also be dangerous. For one thing, the carbohydrate-rich mixture can attract aphids to the wheat, making the treated field more susceptible to brown rust and other fungal diseases.
Another challenge is of a mechanical nature: the sugar in the crop protection spray tank must be carefully removed. It is no coincidence that manufacturers carefully advertise which substances and materials are not recommended to be allowed into the containers. Report on my agraruti According to sugar is one of the so-called raw materials. These are materials useful for the integrated protection of plants, and for environmentally friendly plant nutrition, but not in this form, and not for this purpose. In order for the raw materials to be approved, an evaluation report must be submitted to the European Commission.
