organic based fertilizers

Chemical Fertilizers - These are nutrient supplements for plants manufactured in fertilizer factories from chemicals. They are nutrient specific i.e., they may provide only nitrogen, only phosphorus or only potassium to the soil. They are often used when a particular nutrient is..

The fertility of the topsoil can be restored by taking the following measures. a) Regular use of manures and fertilizers can replenish the minerals used by the crops. Green manuring can also be done. b) Crop rotation should be practiced c) New techniques of applying water benea..

These are nutrient supplements for plants manufactured in fertilizer factories from chemicals. They are nutrient specific i.e., they may provide only nitrogen, only phosphorus or only potassium to the soil. They are often used when a particular nutrient is required in the soil for a parti..

The farm yard manure or organic manure or bio fertilizers and inorganic fertilizers supply the necessary plant nutrients to the soil. Thus, application of such materials increases the nutrient value of the soi..

Pesticides, detergents, chemical dyes and other industrial chemicals and their waste constitute synthetic organic compounds. When present in water, these chemicals can act as toxic poisons for plants, animals and humans. Such chemicals enter the hydrosphere either by usage, by accidental..

As the earth cooled further, the primitive inorganic molecules interacted and combined with one another to form simple organic compounds. Simple sugars, fatty acids, glycerol, amino acids and nitrogen bases (purines and pyrimidines) were probably the simple organic com..

Summary - Aldehydes, ketones, carboxylic acids and their functional derivatives (aryl halides, acid anhydrides, esters and amides) contain a carbonyl group and are highly polar molecules. They boil at higher temperature than hydrocarbon and weakly polar compounds like ethers, of comparable molecula..

Functional groups containing nitrogen are present in a variety of naturally occurring and man made organic compounds. These functional groups impart physico- chemical characteristics to these molecules. These groups are responsible for their unique chemical reactivity patterns and p..

>A strong base dissociates completely in water Example: Sodium hydroxide A weak base dissociates partially in water Example: Ammonium hydroxide In neutralization reaction acids and bases neutralize each other to form corresponding salts and water Acidic and basic solut..

The mechanism of acid-base indicator was developed by Ostwald, which offered an explanation for the colour change with change in pH. All acid-base indicators are weak organic acids or bases, which possess different colours in unionized and ionized states. If..
