INTRODUCTION: realm quality depends on the content of all important(p) numerate give up in it. Soil organic involvement contains biomass, detritus and humus. Humus includes both(prenominal) humic and nonhumic substances. humic substances atomic identification number 18 polymeric, complex, kind, ill-defined compounds. Nonhumic substances argon a group of biomolecules that be in general produced by microbial action and they are less resistant to microbial attack. Soil organic payoff contains 60 to 80% of humic substances. humic substances are separate on the al-Qaida of solubility into three chemical groupings (1) Humic sulphurous (2) Fulvic acid (3) Humus. (1) Humic acid, soluble in stem but non-water-soluble in acid, medium in color and molecular(a)(a) cant, and its oppositeness to degradation is intermediate. (2) Fulvic acid, soluble in both base and acid, lightest in color and lowest in molecular angle and it is more than susceptible to degradation by mi crobes. (3) Humin, insoluble in both alkali and acid, darkest in color and highest in molecular weight and more resistant to microbial attack. The objective of this sight is to put the amount of humic acid and fulvic acid present in Natural prairies and compare them with conventionally till soils. data-based: trio natural prairies and analogous conventionally tilled soils were selected (Table 1).

Soil samples from distributively natural prairies and conventionally tilled sites were collected by barb the soil upto 15cms. International Humic Substance lodge system is being used to determine the amount of Humi c and Fulvic acids in soils.
