Mixture toxicity and interactions of Cu, Ni, Cd and Zn to barley at low effect levels: Something from nothing?
Metal contamination is mostly a mixture of different metals and these multi‐component mixtures can produce significant mixture effects. This study was set up to investigate toxicity of multiple metal mixtures of Cu, Ni, Cd and Zn to plants at metal doses individually causing low level phytotoxic effects. Barley (Hordeum vulgare L.) root elongation toxicity tests were performed in resin ...

Toxicity and bioaccumulation potential of Cr (VI) and Hg (II) on differential concentration by
Eichhornia crassipes in hydroponic cultureIn this work, the phytoremediation of Cr (VI) and Hg (II) ion from water by an aquatic plant Eichhornia crassipes has been studied. Plants were cultured in a double distillated water with modified Hoagland’s nutrient solution at pH 6.8 supplemented with 0, 0.75, 1.50, 2.50, and 4 mg Cr/L as potassium dichromate (K2Cr2O7) and 0, 5, 10, 15, and 20 mg Hg/L as mercuric chloride (HgCl2). They were ...

Damage suffered by swamp morning glory (Ipomoea aquatica Forsk) exposed to vanadium(V)
To elucidate the physiological and morphological responses generated by vanadium (V) in plants, hydroponic culture experiments were performed with swamp morning glory (Ipomoea aquatica Forsk) exposed to 0 to 2.50 mg L−1 pentavalent V [V(V)] in Hoagland nutrient solutions. The concentration of chlorophyll a, chlorophyll b, and carotene peaked at a V(V) concentration of 0.05 mg L−1 and gradually ...

Mixture toxicity of copper, cadmium and zinc to barley seedlings is not explained by antioxidant and oxidative stress biomarkers
Metal mixture toxicity analysis to plants is complicated by mutual interactions. Here, mixture effects of zinc (Zn), cadmium (Cd) and copper (Cu) on barley (Hordeum vulgare L.) root elongation were analysed using oxidative stress parameters. The hypothesis was that toxic mixture effects on plant growth are better explained by biochemical parameters than by exposure information, because the ...

Hydroponic cultivation of lettuce (Lactuca sativa) using effluents from primary, secondary and tertiary + UV treatments
ABSTRACTThe aim of this study was to evaluate the potential cultivation of lettuce (Lactuca sativa) with domestic wastewater effluents with different levels of treatment from a compact WWTP in Brazil. Vegetables were grown in five treatments: nutrient solution (control), secondary effluent diluted 50%, secondary effluent not diluted, tertiary effluent UV irradiated, and UASB effluent. ...

Growth and phosphorus uptake of three riparian grass species
Riparian buffers can significantly reduce sediment-bound P entering surface water, but control of dissolved P inputs is more challenging. Because plant roots remove P from soil solution, it follows that plant uptake can reduce dissolved P losses. We evaluated P uptake of smooth bromegrass (Bromus inermis Leyss.), reed canarygrass (Phalaris arundinacea L.), and switchgrass (Panicum virgatum L.) ...

Research carried out on the use of Amnite AG100 in hydroponically grown crops case study
Project Objective AG100 is a microbially based product produced by Cleveland Biotech Limited UK. It consists of a mixture of components including bacteria. The product is supplied in a cellulose based semi permeable sachet ready for incubation. Work performed during the summer at Cockle Park Experimental Station, Northumberland England and Growers trials in Australia found that application of ...

Data Collection: A Growing Trend in Hydroponics
Hydroponic farming has certain inherent advantages. Plants grown hydroponically will mature on average 25% faster and deliver up to 30% greater yield than plants grown in soil. Creating the conditions necessary for such an increase in plant efficiency requires very close monitoring of the growing environment. Knowing exactly what conditions your plants are growing in at every stage of plant ...

Should organic certification be banned for hydroponic crops?
The USDA recommendation also includes banning aquaponics and aeroponics. The proposal would allow for some types of container production systemsthat meet the nitrogen formulas provided by the Crops Subcommittee. Aquaponics is being defined as a recirculating hydroponic plant production system in which plants are grown in nutrients originating from aquatic animal wastewater. Aeroponics is ...

Hydroponic Spacer, The Solution To Crazy Roots
Among the many diseases that can affect the root zone of the plant, bacterial diseases stand out for being potentially very harmful.. The main problem of these diseases is that there is no effective control of them through chemical treatments, so once the disease takes place it causes severe damage to the crop, reducing production and quality. The most effective way to avoid the negative impact ...

The Superiorities of Extruding Fish Feed Pellets
Fish feeding is one of the most important factors in commercial fish farming because feeding regime may have consequences on both growth efficiency and feed wastage. During the last decade, there has been a marked increase in the use of extruded fish feed pellets for feeding fish. These feed pellets have superior water stability, better floating properties and a higher energy. The main effects on ...

Stud case study
A major vegetable grower in Lantokia, Fiji, using soilless culture systems began to trial Amnite A-100. His crops consisted principally of lettuce, tomatoes, capsicums, cucumbers, zucchinis and melons. Before the trials they had been plagued with root diseases, mosaic virus and insect attack, control of which required constant use of pesticides and ultraviolet lighting. The first trials ...

Cool Season Fertilizing Time is Now
Cool season root and soil fertilizing is the best way to maintain year-round nutrient levels for deciduous trees, plants, and shrubs. In addition, cool season fertilizing prepares plants to grow with gusto as soon as warmer Spring temperatures return. Biofeed Solutions, Inc. has prepared this information to better explain. We will cover dormant root behavior, NPKs and Micro-nutrients.The cool ...

How to grow blueberries: Blueberry growing system in hydroponic greenhouse
In recent years, the demand for berries, and more specifically blueberries, has increased. This has led to an increase in surface area and cultivation techniques. Soil is no longer a problem thanks to the existence of optimal substrates for growing blueberries. Of all the berries, blueberries require the most consideration for greenhouse cultivation. We are going to see some of them, as well as ...

Controlling Nitrogen with Clinoptilolite
With skyrocketing prices on the fertilizer market, and record high contamination levels in runoff from soil leaching, solutions for fixing nutrients in the root zone are of paramount importance. The price of nitrogen fertilizer is always in flux, but as of recently there is a distinct and obvious spike. Fertilizer prices are on the rise. Meanwhile the broad use of fertilizer in agriculture has ...
