Frontiers | Plant mineral nutrition and disease resistance: A
The importance of mineral nutrition on plant disease management can be highlighted as (a) fertilization effect on the incidence or severity of a particular pathogen/host pathosystem, (b) mineral nutrition effect in imparting resistance or susceptibility to plant when provided in different concentration, and (c) effect of specific nutrient ...
Artificial Intelligence for Monitoring and Optimization of an
Recovery of the mineral and grade of the product in an integrated mineral processing plant are two key performance indicators that define plant profitability. Online monitoring and optimization of these parameters helps improve process performance in real-time. However, achieving high product grade and high mineral recovery …
Role of Mineral Elements in Plants
In this article we will discuss about the role of mineral elements in plants. The mineral elements, when present as ions or as constituents or organic molecules, perform several important functions in plants in a number of different ways (Table 9-3).
Electrical conductivity of nutrient solution influenced
To find an electrical conductivity (EC) in the nutrient solution used for pakchoi (Brassica campestris L. ssp. Chinensis) cultivation that optimizes the plant's physiology, growth, and quality, we conducted an experiment with eight EC treatments (from EC0 to EC9.6) in a hydroponic production system (i.e. soilless culture) under …
Essential Mineral Elements in Plants
Nitrogen, phosphorus, calcium, magnesium, iron, manganese, zinc, copper, are few essential mineral elements required for the growth of the plants.
