Mode of action and benefits
Manganese foliar fertilisers are specially developed for application to the leaves. Manganese (Mn) is an essential trace element for plants, necessary for various processes in plant metabolism. A deficiency of this nutrient can lead to various growth problems in plants, such as reduced growth, leaf discolouration and leaf damage. Acute nutrient deficiencies can be quickly counteracted by application to the leaf.
Chelated nutrients improve absorption and plant availability for optimal nutrient uptake.
The application of manganese leaf fertiliser can be combined with other leaf fertilisers and compost tea.
Die Chelatbildung
Ein Chelat ist eine chemische Verbindung, bei der ein Metallion an ein grösseres organisches Molekül, den Chelatbildner, gebunden ist. Diese Bindung bildet einen stabilen und gleichzeitig löslichen Komplex. Der Chelatbildner geht in der Regel Mehrfachbindungen mit dem Metallion ein, wodurch eine ringförmige Struktur entsteht. Diese einzigartige Struktur des Chelats erhöht die Stabilität und Bioverfügbarkeit des Metallions und verhindert, dass es ausfällt oder für Pflanzen oder Organismen unzugänglich wird.
Application and dosage
| Crop | Application rate |
|---|---|
| General | Prevention and correction of manganese deficiency: 2-5 l/ha (0.5-1%) over the leaf, 5-8 l/ha over the soil. |
| Viticulture | 2-3 times 2-3 l/ha from shoots visible as foliar spray |
| Pome fruit | Application as foliar spray: Several times 2-3 l/ha from hazelnut size. For greener background colour 3 times 2 l/ha from walnut size. |
| Stone fruit | 2-3 l/ha from fruit set (foliar spray). |
| Strawberries | 1-2 times 2 l/ha from the beginning of flowering until harvest as foliar spray. |
| Vegetables | 1-2 times 2-3 l/ha as soon as sufficient leaf mass has developed as foliar spray. |
| Potatoes | 1-2 times 2-3 l/ha from 1 week after emergence as foliar spray. |
| Sugar beet | 2-3 times 2 l/ha from 4-leaf stage as foliar spray. |
| Cereals | For winter hardiness, yield, stand strength: in autumn 2-3 l/ha from 3 leaf stage as foliar spray. |
| Rapeseed | 1-2 times 2-3 l/ha from 8-leaf stage as foliar spray. |
