Soil is a nat­ur­al resource formed by wheather­ing (break­down) of rocks. It has been defined as they matrix (sand slit clay) con­tain­ing liv­ing bio­mass and dead organ­ic mat­ter with some con­cen­tra­tion of air and water.  It is a rich source of organ­ic and inor­gan­ic mate­r­i­al that sup­port plant life and micro­scop­ic com­mu­ni­ties. Inor­gan­ic mate­r­i­al include elements

Ecol­o­gy is the study of the rela­tion­ship of organ­isms i.e . plants, ani­mals and microor­gan­ism with their sur­round­ing (envi­ron­ment). Hans Reit­er (1868) gave con­cept of ecol­o­gy. The term Ecol­o­gy is derived from words ‘oikos’ mean­ing home and ‘logos’ mean­ing study. The term was coined in1869 by Ger­man biol­o­gist Ernst haeck­el.  Accord­ing to him Ecol­o­gy is a

Veg­e­ta­tion refers to the plant cov­er or the plant com­mu­ni­ty present on earth . it includes both man made veg­e­ta­tion and nat­ur­al veg­e­ta­tion . the form describes the total plant cov­er in an area or on the sur­face e of the earth as a whole . Teh flo­ra refers to plants of a par­tic­u­lar region present at

All sin­gled celled eukary­otes are placed under pro­tista, bit the bound­aries af this king­dom are not well defined what may be a pho­to­syn­thet­ic pro­tis­tan to on biol­o­gist May be a plant to anoth­er. In this we include chrys­o­phytes , Dinofla­gel­lates , Eug­le­noids, slime moulds and pro­to­zoa under pro­tista. Mem­ber of pro­tista are pri­mar­i­ly aquat­ic. This

Man­age­ment is the process of plan­ning, organ­is­ing, staffing, direct­ing and con­trol­ling the resources of an enter­prise effi­cien­cy and effec­tive­ly for achiev­ing the goals of the orga­ni­za­tion. Man­age­ment helps in achiev­ing group goals, cre­ates a dynam­ic organ­i­sa­tion and increase effi­cien­cy. It also helps in achiev­ing per­son­al objec­tive and devel­op­ment of soci­ety.  Objec­tive of Man­age­ment Organsiation ,
