For tea-drinkers, many of the most important conversations happen over a cup of tea. We have something you may like to share with someone at tea-time. It’s news from the hillsides of Vietnam, the fifth largest tea producer in the world, of the benefits to tea growing from polyhalite application.
 
Topping up tea land

Tea lands, rolling green and productive, are a fabulous landscape and a feast for the eye. But the soil may not provide all that the tea bush roots need to feed on. New and ‘hungrier’ varieties of tea introduced to boost productivity in Vietnam need more nutrients than the soil in traditional tea lands can supply.

 

Polyhalite, this natural marine sedimentary mineral, is a hydrated sulphate of potassium, calcium and magnesium. These alkaline elements are just the ticket for tea plants. So polyhalite, marketed as Polysulphate, was tested on the tea lands in the famous Lam Dong district of Vietnam as an additive to compound N-P-K fertilizers.

Sip the difference
The results are dramatic. Even though tea plants’ tips are harvested relentlessly, the power of polyhalite to improve tea bush productivity is remarkable:

Tea for eternity
These results will surely be a topic of conversation between tea growers over many a cup of tea in Vietnam: where tea-drinking is part of every social occasion.
 
The tea industry in Vietnam has a 3,000 year old history. But it has to continue to evolve in order to be productive, profitable and sustainable. With this new evidence, Polysulphate is proving to be an important part of that.
 
In the meantime, we hope you enjoy your next cup of tea.
