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.

Canola
has a high Sulphur requirement - Sulphur availability should be roughly 1 kg
of sulphur to 4 kg nitrogen, Canola is particularly responsive to sulphur.1 |
Liquid
fertilizers such as Sulfert 8 are commonly used in no till, banded
applications in the Western Cape, South Africa. |
20 – 25 kg N ha-1 is applied at startup, with the
remainder as a topdressing. |
A
sulphur deficiency can be observed when leaves redden along their edges and
become concave in shape. In addition, the youngest leaves change colour from
light green to yellow and their veins darken. |
