RANK() The RANK function instead of assigning a sequential number to each row as in the case of the ROW_NUMBER function, it assigns rank to each record starting with 1. If it encounters two or more records to have the same ORDER BY values, it is said to be a tie and all these records get the same rank.
Why is soil important. Soil plays a vital role in the survival of living beings on the earth. Its importance can be listed as. 1. Soil fertility: Fertile soil supports growth of plants. In-turn these plants produce vital needs to humans like food, clothing, furniture, medicine etc. Even other animals, insects receive food by grazing on plants. 2. Soil microbiology: It provides support for survival of many bacteria, algae, fungi etc..
A soil test can determine fertility, or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive fertility and inhibitions from the presence of non-essential trace minerals.
