Consumption Expenditure Survey - 2003 Livelihood System of Rural Household Survey Aug 9, 2014 Fuwa, Nobuhiko and Marciano,Esther, 2014, "Consumption Expenditure Survey - 2003 Livelihood System of Rural Household Survey", https://doi.org/10.7910/DVN/26627, Harvard Dataverse, V1 1) Measuring living standard of all households in the four sample villages using the state of the art consumption expenditure survey instrument (IRRI had never done such survey in the Philippines because IRRI had traditionally relied exclusively on household income, rather than consumption expenditure, as the measure of living standard/household we...
Availability of Zinc to Different Organic Ligands Under Reduced Conditions in Constrasting Rice Soils Apr 27, 2014 Mercado, Lean Mamerto; Beebout, Sarah, 2014, "Availability of Zinc to Different Organic Ligands Under Reduced Conditions in Constrasting Rice Soils", https://doi.org/10.7910/DVN/24279, Harvard Dataverse, V1 Rice plants sometimes exude organic acids or phytosiderophores into the soil through the roots. These compounds chelate metal cations, such as Zn2+, increasing the availability for nutrient uptake by the plant. And because the chemistry of flooded soils causes many changes in the type and concentration of the cations that are present to react with...
