Mineral composition of vegetable crops fertilized with fish-soluble nutrients

Pea, tomato, radish, and lettuce crops were analyzed for 20 elements by atomic absorption spectrometry. Elemental contents of vegetables that had been fertilized with different rates of fish-soluble nutrients were compared to those fertilized with standard Hoagland nutrient solution. The mineral con...

Description
Summary:Pea, tomato, radish, and lettuce crops were analyzed for 20 elements by atomic absorption spectrometry. Elemental contents of vegetables that had been fertilized with different rates of fish-soluble nutrients were compared to those fertilized with standard Hoagland nutrient solution. The mineral contents of the edible organs were altered by fertilization with fish-soluble nutrients. Pea seeds and tomato fruits responded favorably, with no heavy metal accumulation. Lettuce leaves and radish storage roots showed a greater accumulation of certain mineral elements but no excessive heavy metal accumulation.
