Hydroponics is a soilless cultivation technique in which plants are grown in a nutrient
solution typically made from mineral fertilizers. This alternative to soil farming can be …

Plant scientists usually classify plant mineral nutrients based on the concept of “essentiality”
defined by Arnon and Stout as those elements necessary to complete the life cycle of a …

W hehen rocket science made it possible for humans to ven-ture into space, it became
apparent that human life support was the next pressing challenge. For the short term, this …

Hydroponics is an excellent technique for the cultivation of vegetable crops and other plants,
but organic fertilizers cannot be used in conventional hydroponic systems, which generally …

In order to sustain human life in an isolated environment, an efficient conversion of wasted
nutrients to food might become mandatory. This is particularly the case for space missions …

Effects of corn steep liquor (organic fertilizer, OF) and conventional chemical fertilizer (CF)
on the growth and yield of bok choy (Brassica rapa var. chinensis) in summer and autumn …

Using locally accessible organic materials as fertilizers in hydroponics can represent a
sustainable alternative to the synthetic mineral fertilizers typically used. This study aimed at …

With increasing water shortages, irrigation with reclaimed water is necessary to secure
agricultural production in many regions. This study investigated the feasibility of a novel …

This study compared the growth of potato plants on nutrients recycled from inedible potato
biomass. Plants were grown for 105 days in recirculating, thin-film hydroponic systems …

Due to the high water-and nutrient-use efficiency, hydroponic cultivation is increasingly vital
in progressing to environment-friendly food production. To further alleviate the …
