Symptoms of nutrient deficiency in carambola {Aver rhoa carambola L.), lychee (Litchi chinensis Sonn.) and papaya (Carica papaya L.) trees have been observed periodically in south Florida, but have not been experimentally verified. Young 'Arkin' carambola, 'Mauritius' and 'Brewster' lychee and 'Cariflora' papaya were grown in 26-liter containers filled with coarse silica sand, irrigated with de...

Irradiation of FeDTPA-containing nutrient solutions by a fluorescent plus incandescent light source resulted in the loss of both Fe-chelate and soluble Fe, the formation of a precipitate that was composed mostly of Fe, and a rise in pH. The rate of Fe-chelate photodegradation in solution increased with irradiance intensity and with solution temperature under irradiation, but irradiance had the ...

Economic loss resulting from nickel (Ni) deficiency can occur in horticultural and agronomic crops. This study assesses whether excessive iron (Fe) can induce Ni deficiency. Both chelated Fe and diethylenetriaminepentaacetic acid (DPTA; a commonly used Fe-chelant) induces Ni deficiency in pecan [Carya illinoinensis (Wangenh.) K. Koch]. Foliar sprays of Fe [Fe-DPTA (1.1995 g·L)] during early pos...
