Potassium humate 90%min powder is a high polymer heterogeneous aromatic hydroxy carboxylic acid salt, shiny black flakes or powder. Solube in water and weak alkaline feature. It comprises active groups hydroxy, carboxylic acid salt and nitro and so on.
Adding potassium humate into nitrogenous fertilizerAdvantage: strength the power of nitrogen in nitrogenous fertilizer, reduce the infection of overusing fertilizer.
1. The amount needed per ha.
The early days of plant abandon time and the time of plants rebirth has great infection. Vegetables flowers and fruit trees hurts when transplanting, so we needs potassium humate as additions.
1) Dill, onion, lettuce need 1.6-2.0kg per ha.
2) Tomato, cucumber need 4-5kg per ha.
3) Cabbage, potato, carrot, sugar beet need 7-8kgs per ha.
4) Fruit trees need 10-12kg per ha.
5) All plants 5-6kgs per ha.
a) Soaking the seeds: 24-48hours
b) Using 0.2% solution spraying (flowers or vegetables)
c) Soak 1/3 length of the young plant in 0.2% solution under the 20°C
1) During a period of growth using 0.01% p-ha(potassium humate) solution irrigate 3-4 times
2) After planting using 0.01% p-ha solution irrigate 1 time
After 4 leaves using 0.01% p-ha solution irrigate 1 time
The early time of abloom, using 0.01% p-ha solution irrigate 1 time.
Maturity time using 0.01% p-ha solution irrigate 2-3 times
3) During a growth period (10-12days) using 0.005%-0.01% p-ha solution irrigate 8 times.
4) 5-10g p-ha each hole for young fruit trees.
Improving the soil, avoiding decline, adding output the effect exceeding ammonium phosphate u.s. and other fertilizer much.
High content of potassium and many nutrition including. That makes plants add its outputs, also amending the quality of plants no-poisonous, no-harmful, no-pollution.
Widely used in modern green agriculture.
