What is J.KAY AMINO SOIL?
J.KAY AMINO SOIL is a powdered amino acid product containing 18 naturally derived amino acids.
It has been developed specifically for application through the soil and root zone, where it can be incorporated into an integrated soil, root, and crop management program.

It is suitable for all types of crops, from seedlings and vegetables to field crops, fruit trees, and perennial crops.
Three Key Points to Remember
1. Supports the root system and plant recovery
Suitable for use during periods when plants require additional support, including after transplanting, after harvest, or during periods of environmental stress.
2. Provides amino acids for root-zone application
Contains 18 naturally derived amino acids formulated for application through the soil and root zone.

J.KAY AMINO SOIL vs. J.KAY AMINO
Although both products are based on amino acid technology, they are designed for different application approaches.
J.KAY AMINO SOIL
Designed primarily for soil and root-zone application.
It can be applied by soil drenching, soil spraying, or through drip irrigation systems and is suitable for use together with microbial products.
J.KAY AMINO
Designed primarily for foliar application.
It is applied to leaf surfaces as part of a foliar crop management program.
The two products can therefore be selected according to the intended application method or used as complementary components within a broader crop management program.
