Absorption of Siderite Within a Chemically Modified Poly(lactic acid) Based Composite Material for Agricultural Applications

Abstract Iron is an essential micronutrient for higher plants. Although abundant in most soils, $ Fe^{3+} $ is not available for plant uptake, because of its poor solubility. Ferrous sulfate is a fertilizer used for crops but, $ Fe^{2+} $ is readily oxidized to the plant-unavailable ferric form. It is therefore important to provide $ Fe^{2+} $ to plants, minimizing the loss of this nutrient by oxidation in $ Fe^{3+} $. This paper reports the development of a composite material consisting of a matrix (PLARAM), obtained by the chemical modification of poly(lactic acid), capable of retaining ferrous carbonate (siderite) within PLARAM (PLARAMFe). From the matrix, $ Fe^{2+} $ is released into the soil, enhancing its bioavailability. PLARAM and PLARAMFe films were obtained and their water wettability was studied. One side of the films was more hydrophilic than the other, turning this material attractive as a protective film when it is necessary to avoid loss of humidity..
