As I touched on earlier, bacteria turn nitrites into much less harmful nitrates. In large enough numbers, these bacteria eat nitrites as fast as they are produced. So, what you are doing is introducing more of them into your aquarium. ...
The bacteria are used to break down the ammonia into the much less harmful nitrites and nitrates (they are essential for the nitrification cycle). Some bacteria (i.e.Nitrosomonas) convert ammonia to nitrites, while others (i.e.Nitrobacter) convert nitrites to nitrates. ...
Because of the nature of this technology, plants are permitted to dip directly in their roots into the nutrient-rich solution and subsequently plants can absorb faster the nutrients and in an easier way in comparison with soil-based crops. Because of this process, plants grown in hydroponics ...
How does sodium nitrates and nitrites affect the color of the meat and what are the mechanism? What are some of the consequences of leaving a stain on a bacterial smear too long (over-staining)? What about under-staining? (a) How is vitamin D synthesized? (b) What eff...
Nitrates are not the only ions that plants need to take in from the soil They need phosphate, sulphate, iron, potassium and magnesium ions This is the reason why farmers and gardeners add fertiliser to the soil These fertilisers usually contain nitrates, phosphates and potassium (NPK) ...
(e.g. one hour) to remove waste metabolites for treatment and return high quality water. Most recirculation systems are designed to replace 5 to 10 per cent of the system volume each day with new water. This amount of exchange prevents the build-up of nitrates and soluble organic matter ...
You can also find beet greens, the leafy top of the beet plants that are totally edible and offer loads of B vitamins. Here's what those nutrients can do for you. Lower Blood Pressure Beets help your heart by lowering blood pressure.1 "[They] contain inorganic nitrates that the body...
The reduced pH levels inhibit the ability of nitrifying bacteria to transform ammonia, one form of nitrogen, into nitrates, a second form of nitrogen that is vital for weeds to flourish.Play Video Inhibiting Pests and Diseases The vast majority of disease causing microorganisms are anaerobes, ...
–2% is absorbed on soil colloids • These are positively charged ions –0.2% is dissolved in the soil water • Usually negatively charged, nitrates and phosphates Soils and Plants • The structure of many soils changes with depth, revealing ...
