Nitrate leaching from layered double hydroxides in tropical and temperate soils

Communicating Nitrogen Loss Mechanisms for Improving Nitrogen Use Efficiency Management, Focused on Global Wheat

“…It is desirable that N is moved into the soil through water solubility, as this will provide protection against volatilization losses, and it is more likely the N will be in the rooting zone, but if there is too much leaching, the NO 3 − will pass the root zone and be lost to the plant. There is substantially more NO 3 − leaching in temperate soils, which have limited capacity for anion exchange, compared to tropical soils, which have a much greater potential for anion retention [165].…”

Acidity is an important regulator of volatilization; pH affects the balance of NH3 and NH4 + in the soil.…”

Water-based synthesis and nitrate release properties of a ZrIV-based metal–organic framework derived from l-aspartic acid

“…1 Hydrogel formulations, ethylcellulose-coated granules of ammonium nitrate and nitrate-intercalated layered double hydroxides (LDHs) are among the solutions proposed in the literature for controlled release of nitrate fertilisers. [6][7][8][9][10][11] The use of metal-organic frameworks (MOFs) in agriculture is attracting growing interest. [12][13][14] The porous nature of MOFs makes them suitable for use as host platforms for controlled release of both nutrients and pesticides, [15][16][17][18][19] as well as for their removal from the environment via either adsorption or degradation.…”
