Does Foliar Feeding Work?

It is becoming a common practice to foliar feed crop plants when spraying herbicides, insecticides or fungicides, writes agronomist Daniel Davidson on If you are making a pass across the field, why not throw in nutrients, sugars, biologicals or growth stimulants to give plants a boost? Foliar feeding can supply nutrients when they are lacking or unavailable in the soil, or when roots are stressed and not active.


But the question is, do you get a clear economic return or are you pouring money down the drain?

Many farmers foliar feed their crop once or twice, spraying on a cocktail of nutrients and other products like sugars, growth stimulants and pesticides. There is a wide array of products available today from your retailer and you have a lot of products to choose from. But how do you know which product to buy or how many different ingredients it should have? The marketplace is crowded, claims can be confusing and you have to rely on the salesperson for sound advice — or do your own testing.
