To All Members of Fertasa – Articles Received by Fertasa
Fertasa receives Scientific Articles from a number of sources: identified, volunteered and commissioned.
In order to make Fertasa members aware of these, and to give them the opportunity to comment, suggest additions, and possible alterations where applicable, the Editorial Committee has decided to place them under “New Scientific Insights” on the Fertasa Website.
These contributions will be available for comment for two months. Thereafter they will be placed under:
- “General Scientific Articles”
- “Fertilizer Handbook Updates”
It is especially important that these articles must meet the needs of Members in being inclusive, objective and scientific.
Your inputs are therefore considered extremely important.
All correspondence in this regard should be sent to candice@fertasa.co.za and please CC robin@fertasa.co.za.
We look forward to hearing from you.
