Project Number: 8042-21000-303-007-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: Apr 1, 2020
End Date: Mar 23, 2025
To determine the influence of abiotic stresses (drought, mineral deficiency, heavy metal toxicity, soil acidity, light quality) on chemical composition (micro and macro nutrients, heavy metals) of tropical plants experiments conducted in field, greenhouse and growth rooms at Beltsville, Puerto Rico, Brazil, Peru, Colombia.
Plant (cacao, cover crops) and soil samples of tropical crops will be collected from field, greenhouse and growth chamber experiments carried out in Peru, Brazil and Colombia and transported to the U.S. under APHIS soil and plant import permits. Plant mineral compositions (C, N, Ca, Mg, K, P, Na, S,Al, Zn, Cu, B, Fe, Mn,Cd, Pb etc.) will be determined at the University of Florida, Indian River Research and Education Center (IRREC)- Fort Pierce, Florida. Plant (cacao, cover crops) samples from experiments conducted at Beltsville, Maryland and Puerto Rico facilities of ARS will be analyzed for macro and micronutrients (N, C, Ca, Mg, K, P, Na, Al, Zn, Cu, B, Fe, Mn, Cd, Pb etc.) at the University of Florida, IRREC- Fort Pierce, Florida.
