Chloride and sodium are the main ions contributing to soil salinity in many regions but chloride is an essential element necessary for plant growth and development. It also controls the growth of some pathogens in plants. In this experiment, the effect of the chloride ion in nutrient solution on yield and fruit quality of two strawberry cultivars: ‘Selva’ and ‘Camarosa’ grown in hydroponic cult...

A balanced nutrient supply is essential for the healthy growth of plants in hydroponic systems. However, the commonly used electrical conductivity (EC)-based nutrient control for plant cultivation can provide amounts of nutrients that are excessive or inadequate for proper plant growth. In this study, we investigated the kinetics of major and minor nutrient uptake in a nutrient solution during ...

The effect of various concentrations of sulphates in the nutrient solutions (I – 200, II – 400, and III – 600 mg SO4 2dm) on sulphur content in plants as well as plant height and leaf area of tomato plants grown with nutrient film technique (NFT) were investigated. Total-S and S-SO4 levels were determined in the leaf blades of the upper, medium and lower plant parts, during 3 phases of tomato g...

The production innovations have been evolving more and more towards organic, sustainable or environmental friendly systems. Contemporarily, the yield and the quality of crops must be assured. The reduction of fertilisers may be obtained by improving the nutrients uptake or their utilisation by the plants. The aim of our work was to verify if the progressive reduction of nutrient solution concen...

There are three variations of the fermentation process. In batch fermentation, a sterilized nutrient solution in the fermentor is inoculated with micro-organisms and incubation is allowed to proceed. During the course of the fermentation, oxygen is added (as in the case of aerobic microorganisms) and an acid or base to control the pH. The composition of the culture medium, the biomass concentra...

There is currently much debate about sources of pollution, particularly nutrient pollution of surface and groundwaters. It frequently appears that everyone is quite confident everyone else is contributing far more than they are. The reality, particularly for nutrient pollution, is that we all are part of the problem and must be part of the solution. This paper offers a science-based perspective...
