Foliar Iron Fertilization: A Critical Review

Foliar Iron Fertilization – A Critical Review

Foliar fertilization in citriculture

certainly not a new concept to the citrus industry. For more than five decades, foliar fertilization of citrus has been recommended to correct zinc, manganese, boron, copper and magnesium deficiencies. It is now common knowledge in agriculture that properly nourished crops may tolerate insect pests and diseases. Traditionally, citrus growers try to achieve optimum nutrition through direct soil ...

Foliar Fertilization of Soybeans

Extensive research addressed foliar fertilization of soybeans at reproductive stages during the 70s and 80s. The soybean plant has been characterized by markedly reduced root activity during late seed development and increased translocation of nutrients and metabolites from other tissue into the seed. This depletion of nutrients from leaves could result in decreased photosynthesis, leaf senesce...

1 Foliar iron fertilization of peach ( Prunus persica ( L . ) Batsch ) : effects of iron 2 compounds ,

18 Experiments to assess the capability of different combinations of Fe-compounds and 19 adjuvants to provide iron (Fe) via foliar application to Fe-deficient plants have been 20 carried out. A total of 80 formulations containing i) one of five Fe-compounds 21 (FeSO4.7H2O, Fe(III)-citrate, Fe(III)-EDTA, Fe(III)-DTPA, Fe(III)-IDHA), ii) a 22 surfactant (Mistol, alkyl-polyglucoside1 or alkyl-poly...

Uptake of Mineral Nutrients from Foliar Fertilization (review)

The aim of this paper is to review the current knowledge on the uptake of mineral nutrients from foliar fertilization. Despite many studies carried out on mineral nutrient absorption by leaf tissues, many aspects of foliar fertilization are still unknown. At present, it is believed that such fertilization of plants is a valuable complement to the application of nutrients to the soil. Foliar fer...
