This fertilizer contains oil seeds extracts. Because it is made from organic material and plant extracts, plants recognize it and can absorb it directly. Fertilizers with chemical origin, need to be converted to sugars before plants can use them. 

Another big advantage of Nature Source is that the salt levels are very low so the chance of burning your plants is very small. This is a good fact to know when watering small plants. Not only can it get absorbed through the roots, it can also be applied as a spray on fertilizer. This way it will get absorbed through the leaves of the plant. This may be handy for air plants and cactus."
