| Fertilizer guidelines are influenced by numerous variables including crop type, production methods, crop rotation, soil texture, rainfall, and crop production potential. The following guidelines are approximations based on the amount of N and S removed when the crop is harvested only. Fertplan assumes no responsibility or liability for the information supplied.

plays an important
role in reducing Wheat’s susceptibility to disease. |
- Increases
the plant uptake of Phosphorus, Manganese, and Zinc.1
|
- In new
growth, sulphur deficiency can be seen when the whole plant or newly emerging
leaves go yellow – usually more pronounced between the veins.
|
- Sulfert
8’s ammonium source of Nitrogen is less susceptible to Nitrogen loss to
volatilisation so it can be applied as a topdressing.
