What is the best fertilizer to use for rubber trees?

Fertilizer for rubber trees in Thailand

According to the Thailand agricultural department:

For the first 6 years, use 20-10-12 in the following amounts per rai:

First 6 months: 7kg per rai / 80 grams per tree
7 - 18 months: 9kg per rai / 110 grams per tree
24 - 30 months: 10kg per rai / 120 grams per tree
31 - 53 months: 15kg per rai / 180 grams per tree
After 53 months: 16kg per rai / 200 grams per tree

After 6 years, use 15-7-18
and after 20 years, use 20-8-20

I heard advice from one farmer, who is currently cutting his trees, he mixes his fertilizer, 50% 15-7-18 and 50% 46-0-0, he says this is working very well for his trees.
