A foliar fertilizer is one which is applied directly to the leaves of a growing crop. It's normally done with a tractor- or self-propelled spraying rig. The concentrations are usually quite low because the plant leaves can only absorb a limited amount of any nutrient, and so this practice is normally limited to the application of micronutrients, those which the plant needs only in very tiny amounts.
Fertigation fertilizer, on the other hand, is the application of any fertilizer through an irrigation system. The target for the fertilizer is the root zone of the crop, not the leaves as with a foliar product. While the amounts applied are still relatively limited, this method is normally used to apply small amounts of the major nutrients in cases where it is difficult to get enough fertilizer applied using regular methods, or when excess precipitation may have washed nutrients out of the soil. Even though the irrigation system may apply water and fertilizer to the leaves, the intent is to wash it off into the root zone.

How does leaf structure affect foliar fertilization?
The cuticular and the stomatal level of the leaf structure affects foliar fertilization.
What is the difference between the effectiveness of solid fertilizers versus liquid fertilizers?
Fertilizer efficacy is more related to formulation, timing of application, and soil type than solid vs. liquid. Some solid formulations can be made more available to the crop than their liquid counterparts. Within US commercial agriculture, the difference between solid vs. liquid (all other factors being equal) is generally considered negligible. Liquid and solid both play a valuable part. For example, if a corn crop doesn't get enough nitrogen applied before the crop is planted, the farmer can attempt to apply a "rescue" application of liquid nitrogen to the growing crop. However, these treatments are normally much less effective for the cost per acre than if he had applied enough to begin with.
Can boron deficiency in apple and pear trees only be treated with soil applications?
No, soil applications of agricultural borax aren't the only treatment for apple [Malus domesticus] and pear [Pyrus spp] trees growing in boron deficient soil. Another option is foliar control, or spraying on the trees' leaves. Just have solubor applied at the rate of 1.0 pound per 100 gallons once during the late bloom and once during the early post bloom each year.
Do Plants Absorb Nutrients Through their Leaves?
Yes, plants can absorb nutrients through their leaves, but this is not their primary mode of nutrient intake. Most plants primarily absorb nutrients from the soil through their roots. However, foliar feeding, or the application of nutrients directly to the leaves, can be used to provide supplemental nutrition to plants.
How does the aloe Vera plant obtain water and nutrients?
Aloe Vera plants obtain water and nutrients primarily through their roots, which absorb water and minerals from the soil. They also have specialized cells in their leaves called parenchyma cells that store water and nutrients for times of drought. Additionally, they can absorb nutrients through their leaves via foliar feeding.
Different methods how to apply fertilizers?
Fertilizers can be applied through broadcasting, where they are spread evenly across the soil surface. Alternatively, they can be injected into the soil around the plant roots using drip irrigation or fertigation systems. Foliar feeding involves spraying the fertilizer directly onto the leaves for absorption. Additionally, fertilizers can be applied through banding, where they are placed in a concentrated line in the soil near the plant roots.
What are the different methods of applying fertilizer?
The different methods of applying fertilizers are broadcasting,banding,side dressing,watering with fertilizer solution,foliar feeding,using slow-release fertilizers.
What are foliar?
Foliar is defined as ..... Of or relating to a leaf or leaves.
How does leaf structure affect foliar fertilization?
The cuticular and the stomatal level of the leaf structure affects foliar fertilization.
Definition for foliar Application?
Foliar fertilizers are fertilizers that are applied to boost nutrient density in crops and to correct nutrient deficiencies.
Definition of foliar application?
something applied to the leaves
Is it possible to use expired medicines as a fertilizer?
my students conducted a study on that matter. Results show that expired multivitamins is effective in enhancing the chlorophyll content of plants as compared to commercial foliar fertilizer. More chlorophyll means more sunlight is trapped more energy is produced resulting to the growth of plants. But that is just for growth, we dont know yet the effect of expired multivitamins to the nutritional value of plants:)))
Can you foliar feed with GH nutrients?
CAN I FOLIAR FEED WITH GH NUTRIENTS? Answer: Of course. Make sure you use a weaker nutrient solution than you would for root feeding. Avoid foliar feeding in the heat of the day and under excessive sunlight. Generally, the best times to foliar feed are in the early morning and late afternoon. Make sure you spray the undersides of the leaves. This is where the stomata or "lungs of the plant" are located, and where maximum absorption occurs. This answer was collected from: http://www.generalhydroponics.com/genhydro_US/faqnute.html
Do farmers use fertilizer in planting soybeans?
In US industrial farming systems, farmers try to fertilize soybeans only once, prior to planting, based on soil testing. If they observe a problem during the year, they may do some foliar fertilizing based on tissue testing, but this is somewhat rare.
What are the control methods for nematode disease?
The four main nematode diseases are known as foliar, lesion, pin and root knot. Foliar nematode disease is controlled by spraying leaves. The other three typically are controlled by soil drenches.
What will be the effect of using yeast as foliar spray?
use 5ml per litre on cucumbers.

personally i dont think its effective at all
