Manures The deficiency of plant nutrients and organic matter in the soil is made up by adding manures and fertilizers to the soil of crop-fields. Both manures and fertilizers are major sources of nutrients of plants‚ so they are used in crop production. Besides water CO2 and sunlight plants required no. of elements for their growth. These elements are known as nutrient. Plants get their elements from the salt of these elements present in the soil. But after repeated cultivation of plants soil become

D4 H and E staining procedures Haematoxylin and eosin staining is a technique used by pathologists to add definition to nuclei and other parts of a cell in tissue samples under a microscope so that they can see it better when analysing the cells form and abnormalities. The H&E technique is the most commonly used in histology and the diagnoses of malignancies is based largely on the results of this procedure. The dyes will specifically stain elements of a cell or tissue because the dyes have a high

amount of reducing sugars. Biological principles: Benedict’s test for reducing sugar: Reducing sugars include all monosaccharides (glucose) and some disaccharides (maltose). Benedict’s solution contains copper sulphates. Reducing sugars reduce copper(2) ions present in the blue copper sulphate solution to insoluble red brown precipitates. The initial blue colour of the mixture turns green‚ then yellowish and may finally form a brick-red precipitates in the presence of reducing sugars. The amount of

The parameters like pH‚ calcium‚ hardness and total alkalinity exceeded the permissible limits of WHO; whereas parameters like magnesium‚ sodium‚ nitrates‚ chlorine and sulphates were found to be within the permissible value. The content of Dissolved oxygen found to be present in the lake water was found to be nil‚ hence the values of biological oxygen demand and the chemical oxygen demand were also found to be zero. This
