IMPROVEMENT OF PHOSPHATE FERTILIZATION METHOD IN WETLAND RICE

open access: yesAGRIVITA Journal of Agricultural Science, 2014
The low efficiency of Phosphate fertilization on wetland rice may be overcame by using quickly dissolve P fertilizer. However, for soils containing high dissolve Fe, such as Alfisol and Oxisol, will induce the formation of Fe-P bonding. Therefore, to use

Soil organic carbon dynamics of improved fallow-maize rotation systems under conventional and no-tillage in Central Zimbabwe [PDF]

open access: yes, 2008
Fallowing increases soil organic carbon (SOC) during the fallowing phase. However, this benefit is lost quickly during the cropping phase. The objective of this study was to evaluate SOC dynamics of an improved fallow-maize rotation under no-tillage (NT)

Effect of foliar sodium selenite fertilization on oxidative stress and productivity in Olea europaea L., biofortification and quality of extra virgin olive oil

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 1, Page 376-385, 15 January 2026.
Abstract Background Fertilization of plants with selenium (Se) can enhance their resistance to abiotic stresses and improve human health and nutrition. However, Se fertilization in olive trees remains underexplored. This study evaluated the effect of foliar sodium selenite fertilization on leaf Se content, oxidative stress, olive tree productivity ...
