Bioavailability of Nutrients in Seeds from Tropical and Subtropical Soybean Varieties
(Taylor & Francis Inc, 2016-01-01)
The selection of varieties or species of plants with higher nutrient uptake efficiency and nutrient concentration for biofortification of food crops is a key tool to reduce malnutrition. Soybean (Glycine max L. Merr) is ...
Diagnosis of nutrient composition in fruit crops: Major developments
(2019-11-27)
Early methods of tissue diagnosis opposed the concept of critical nutrient concentrations supported by the laws of the minimum and the optimum to the more complex one of nutrient balances. But this proved to be a futile ...
PERIODICITY OF EXPOSURE OF HYDROPONIC LETTUCE PLANTS TO NUTRIENT SOLUTION
(Univ Fed Rural Semi-arido-ufersa, 2020-01-01)
A balanced periodicity of the nutrient solution flow is essential for better agronomic performances and low production costs in hydroponic systems. Thus, the objective of this work was to evaluate the effect of periodicity ...
Poor correlation between phytoplankton community growth rates and nutrient concentration in the sea
(Göttingen, 2015)
Nutrient availability is one of the major factors
regulating marine productivity and phytoplankton community
structure. While the response of phytoplankton
species to nutrient variation is relatively well known, that
of ...

Effects of different nutrient concentrations and reuse of substrate in tomato production
(Int Soc Horticultural Science, 2015-01-01)
Reusing the substrate in subsequent crops has been proposed due to several advantages, especially economic and environmental ones. Furthermore, the electrical conductivity of the nutrient solution can directly influence ...
