Abstract:

The recovery of nutrients from wastewater streams for their later use in agricultural fertilization is an interesting approach. Wastewater recovered magnesium phosphate (MgP) salts were used in a forward osmosis (FO) system as draw solution in order to extract water and to produce a nutrient solution to be used in a hydroponic system with lettuces (Lactuca sativa, L.). Owing to the low solubility of the MgP salts (i.e., struvite, hazenite and cattiite) in water, acid dissolution was successfully tested using citric and nitric acids to reach pH 3.0. The dilution by FO of the dissolved salts rea

Among the sprayed treatments, NaCl provided significantly less CPM control when applied at a low (0.05 M) concentration, as compared with CaCl2 and MgCl2. When sprayed applicatio

Abstract:

ABSTRACT Soil salinity and sodicity are the global problems and pose a serious threat to agriculture sustainability. The distribution of salt affected soils exist mostly under arid and semi-arid climates where rainfall is inadequate to leach salts from/out of the root zone. These soils have poor fertility, generally with low availability of nitrogen, calcium, zinc, iron and manganese. Therefore, judicious nutrients management on the principle of INM in these soils is as important as their reclamation. In these soils, crops respond differently to applied nutrients due to their diverse chemical

Abstract:

Hydroponic systems are efficient for studying plant nutrition. It is often desirable to adjust individual nutrients for unique species’ needs and/or to create multiple nutrient deficiencies within the same study. However, this is challenging to do with traditional solutions as nutrients are generally added as dual nutrient salts, such as when varying phosphorus (P) concentration also affects nitrogen concentration; potentially, the chemical form of the nutrient taken up when ammonium phosphate is the source for P. This can create unintended consequences with nutrients other than those intended

The effect of culture media on antheridial configuration was found to be due to nutrient concentration.

The “new” production in spring is produced mainly by chain forming diatoms.The dissipation of the spring bloom is due to nutrient depletion in the stabilised surface layer, loss of cells by sinking and grazing by herbivorous zooplankton. After the nutrient concentration is lowered, the rate of production will depend primarily on the rate of replenishment of nutrients. In open ocean environments we

Hydroponics is the practice of growing crops without soil, which relies on careful calibration of pH, EC (electrical conductivity) and nutrient availability to promote plant growth and yield. In hydroponics, pH is an important factor governing how nutrient availability is affected. Ideal pH range for most of the crops is 5.5-6.5. pH is important to determine acidity and alkalinity of a solution and it further affects nutrient absorption. pH management is different in Deep water Culture, Nutrient Film Technique and System of Flooded tubes.

Abstract:

Honey contains many monosaccharides as fermentation materials for mead production, but little nitrogen or minerals. Consequently, the quality of the final product is inconsistent owing to a lack of nutrients. Here, we sought to identify valuable additives that can be used as nutrient sources for efficient mead production. We examined the effects of diammonium hydrogen phosphate, ammonium sulfate, and salts on the alcoholic fermentation of honey must by dry yeast. The results showed that the alcohol concentration in the mead increased with the addition of diammonium hydrogen phosphate but decre

Deep sea water (DSW) is a globally utilized source of renewable energy and other resources. To understand the characteristics of DSW resources in the South China Sea, in July 2022, the Guangzhou Marine Geological Survey (GMGS) investigated temperature, salinity, pH, dissolved oxygen (DO), inorganic salts (DIN, PO43−-P, and SiO3-Si), heavy metals (Hg, Pb, As, and Cd), trace elements (Cu, Zn, Fe, Mn, Ni, Se, and Mo), and other related indicators. The results of this investigation elucidate the horizontal and vertical changes in the physical and chemical properties of deep sea water in the Xisha

The objective was to quantify the effect of water-soluble fertilizers on concentration of free chlorine level in a sodium hypochlorite solution. Research on the disinfestation strength and phytotoxicity risk of chlorine compounds is needed, because control of waterborne pathogens has been based on response to free chlorine, whereas dual injection of fertilizer and chlorine is a common horticultural practice. Free chlorine from sodium hypochlorite was applied at 2.6 mg·L−1 chlorine (Cl) to deionized water only (control) or deionized water with 11 nutrient solutions at 200 mg·L−1 nitrogen (N). N

Nutrients, conductivity and δ18O were monitored in surface and subsurface (using ceramic tipped piezometers) lake inflows during summer in near natural and human impacted catchments. The nutrient levels were highly variable but generally higher during the last weeks of the flow, in both subsurface waters and in human impacted catchments.

There is world-wide interest in disposal technologies suitable for handling farm wastes. The Northern Ireland mushroom industry generates 200,000 tonnes/year of “spent” mushroom compost waste containing excess salts (P, K, Ca) and heavy metals. Its disposal by landspreading is restricted by EU, U.K. legislation. Farmers in Europe and the United States use this waste as a soil nutrient improver, but such operations are deleterious to the environment owing to microbial loading of soil and the release of human and animal pathogens. An ideal option is to reduce salt levels and pathogen content bef

Performance of the mesophilic (35°C), two-phase anaerobic digestion (TPAD) system was about the same as that of thermophilic single-stage, high-rate digestion at a 10-day HRT as judged in terms of methane yield (0.17 SCM/kg VS added) and VS reduction efficiency (43%).

In all the experiments the best development of tomato plants was observed when nutrient solutions containing 1/3 of full doses of potassium were applied (i.e. when the N : K ratio = 0.84). On the other hand, the poorest development of plants was observed in combinations with 1/100 of the full potassium dose. Tenfold doses of potassium added to the nutrient solution de-pressed markedly plant growth, particularly at pH 7.6. The supply of potassium in the nutrient solution was correlated with the nitrogen, potassium and calcium amounts absorbed by the plants.
