POTASSIC HUMIC AMENDMENT
ACIDO HUMICO PSW is a liquid potassium humic amendment obtained from American Leonardite.
ACIDO HUMICO PSW has been developed by PSW S.A, for foliar application and drip irrigation. The synergism between the seaweed and the humic substances of ACIDO HUMICO PSW help enhance the soil´s cation exchange capacity in order to obtain better results at a physical, chemical and biological level. Its application is linked to key moments such as leaf formation and development, pre-flowering, fruit set, bulb enlargement, bud formation, and any stress condition that may occur during the cultivation period.
