Importance of living organisms in soil formation

Importance of living organisms in the formation of soil, Not all living organism play a part in soil formation, so here are the few major list of the most important ones the directly have massive impart in the process of soil formation through a process called weathering–soil living organisms

how living organisms helps in soil formation

Worms and insects like the termite helps in breaking down and decomposition of organic matter.
Human activities on the rocks in the forms of mining, drilling and other quarry activities like making roads also affects the rate of soil formation.
Construction of roads by humans like in the farm, therefore leads to breaking of rocks soil living organisms

The roots of trees growing on top of rocks causes the rock to crack or break gradually to form soil.

It is worthy of note that the process of soil formation takes a gradual and precise direction which happens over time which invariably means that time is also a factor of soil formation.

A long period of time allows for the development of mature soils whereas a short period of time allows for immature formation of soil soil living organisms

It will take some time for a small pieces of rock to break into grains of soil. And it will also take time for living organisms like plants and animals to decay, turn humus and become part of the soil–soil living organisms

EFFECTS OF ORGANISMS ON SOIL FORMATION

SOIL ORGANISMS PLAY A VITAL ROLE IN THE DEGRADATION OF ORGANIC MATTER AND SUBSEQUENT SOIL HUMUS FORMATION. WHEN PLANTS DIE, LEAVES ARE DROPPED ONTO THE SOIL SURFACE WHERE MICRO ORGANISMS CAN “ATTACK” AND DECAY PLANT TISSUE

THE ORGANIC MATTER IS USED AS AN ENERGY SOURCE FOR MICRO ORGANISMS, INCREASING THEIR POPULATION IN THE SOIL. THESE ORGANISMS UTILIZE EASILY DIGESTIBLE MATERIALS (Like   SIMPLE SUGARS AND CARBOHYDRATES) FOUND IN THE PLANT MATERIAL, LEAVING MORE RESISTANT MATERIALS (SUCH AS FATS AND WAXES) BEHIND THE MATERIAL LEFT BEHIND IS NOT EASILY DECOMPOSED; IT COMPRISES THE HUMUS FOUND IN SOIL. HUMUS ACTS AS A BINDING AGENT, ESSENTIALLY HOLDING PRIMARY SOIL PARTICLES (SAND, SILT, CLAY) TOGETHER TO FORM SECONDARY AGGREGATES ’. THESE ORGANISMS AND THE HUMUS THEY HELP CREATE AID IN THE SOIL DEVELOPMENT AND THE FORMATION OF SOIL HORIZONS.

THE EFFECT SOIL ORGANISMS, SPECIFICALLY VEGETATION, HAVE ON THE CREATION OF HUMUS AND SOIL FORMATION.
THE FIGURE SHOWS THE PERCENTAGE OF HUMUS CONTENT TENDS TO BE GREATER IN GRASSLAND SOILS, AS COMPARED TO CONIFEROUS FOREST SOILS. THE REASON BEHIND THIS OBSERVATION IS QUITE SIMPLE;

DEAD GRASSLAND PLANTS TEND TO HAVE A SOMEWHAT NEUTRAL PH AS COMPARED TO FOREST NEEDLES, WHICH TEND TO HAVE AN ACIDIC PH soil living organisms

THE RELATIVELY BASIC PH OF THE GRASSLAND PLANTS MAKES THEM EASIER FOR MICROORGANISMS TO DEGRADE AND TURN INTO HUMUS. OPPOSITELY, NEEDLES ARE MORE DIFFICULT FOR MICROORGANISMS TO DEGRADE;

formation of humus through soil living organisms

THUS, THE HUMUS CONTENT OF CONIFEROUS FOREST SOILS TENDS TO BE LESS THAN GRASSLAND SOILS. THE ACIDIC NATURE OF THE FOREST LITTER, HOWEVER, CAUSES ACIDS TO FLOW THROUGH THE soil profile AND HELP DEVELOP HORIZONS QUICKER THAN A GRASSLAND SOIL. THE ACIDS CAN DISSOLVE SOIL MATERIALS AND REDEPOSIT THEM DEEPER IN THE SOIL, WHICH HELPS TO MORE QUICKLY CREATE SOIL HORIZONS.

THAT HUMUS CONTENT DECREASES WITH SOIL DEPTH. THIS MAKES SENSE, BECAUSE HUMUS IS DERIVED FROM DECAYING PLANT MATERIAL WHICH ORIGINATES AT OR NEAR THE SOIL SURFACE. read how to make compost manure here
