We are not the most professional ,we just learn little more ,stuy little more ,know little more ,but we are pleasure to share
with our customer,tell them everything we know.
We classify the NPK water soluble fertilizer into four level ,we meet many customers from the worldwide,everytime they come
to use take lots of confuse and complain.
All the products it looks the same, the cotent is the same ,and everybody say theirs is 100% water soluble but actually
they are not the same,so that's why some material is much more expensive,some is much cheaper.
Here the Level we classified.
Level 1.: chemical synthesis ,real 100% water soluble ,no impurity , no suspended material no sulfate,no chloride.
Level 2.: physical mixing,use 100% water soluble material ,like MAP,DAP,MKP,DKP,KNO3,urea etc.
Level 3.: physical mixing,sulphate base, potassium origin from K2SO4,part nitrogen from ammonium
Level 4: physical mixing,chloride based and cheap nitrogen origin,like ammonium sulphate or ammonium chloride
