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
