  Soil life
Soil life is a collective term for all the organisms living within the soil.
The mineral content of the soil and its physical structure are important for their well-being, but it is the life in the earth that powers its cycles and provides its fertility.
In terms of soil and humus creation, the most important fungi tend to be saprophytic[?], that is, they live on dead or decaying organic matter, thus breaking it down and converting it to forms which are available to the higher plants.

 Soil   (Site not responding. Last check: 2007-11-02)
Soil forms the upper-most layer of the earth's crust and is made up of inorganic and organic matter.
Clay soils have a large proportion of the smallest particles and are the least suitable for plant growth.
Soils which have approximately equal proportions of sand and clay are called loams and are best for plant growth because they contain enough air and can hold moisture.

 Soil life - Wikipedia, the free encyclopedia
Soil life or soil biota is a collective term for all the organisms living within the soil.
Without the activities of soil organisms, organic materials would accumulate and litter the soil surface, and there would be no food for plants.
Aerobic bacteria are most active in a soil that is moist (but not saturated, as this will deprive aerobic bacteria of the air that they require), and neutral soil pH, and where there is plenty of food (carbohydrates and micronutrients from organic matter) available.

 Soil Management - Soil Life   (Site not responding. Last check: 2007-11-02)
Saturated soils have a weak structure and are prone to compaction.
Spring soil is highly susceptible to wind and water erosion, because soil is often bare and soil structure is weak.
Soil water levels begin to recharge as temperatures drop and evaporation and transpiration slow.

 Scenic Hills Nursery -- Oak Wilt Specialists in the Texas Hill Country
Soil is one of the building blocks of life and is crucial for the growth of the food chain.
This system is referred to as "soil life", as the microbes are living organism in the soil, that make all nutrients exchangeable to plants.
Understanding the function of microbes in the soil is essential, as it is these very same bacteria and microbes that create the exchange conditions of minerals and nutrients for plants and trees.

 Lesson 7. Soil Biological Properties
Microscopic life forms in the soil are generally called the "soil microflora" (though strictly speaking, not all are plants in the true sense of the word) and the larger animals are called macrofauna.
Soil animals, especially, the earthworms and some insects tend to affect the soil favorably through their burrowing and feeding activities which tend to improve aeration and drainage through structural modifications of the soil solum.
Soil bacteria belonging to the genera Rhizobium and Bradyrhizobium (and a few others) are capable of inducing the formation of nodules on roots of specific legumes (plants like peas, beans, peanuts, soybeans, alfalfa etc.) and fixing large quantities of nitrogen in these structures.

 KRASILNIKOV: INTRODUCTION
According to him, soil should be called the "daily" or outward horizons of rocks regardless of the type; they are changed naturally by the common effect of water, air and various kinds of living and dead organisms.
According to him,the notion of soil and its fertility are inseparable.
The degree of soil fertility is determined by the intensity of the life processes of the microbial population.

 Natural Soil Bacteria, soil life
Soil biology is as critical to soil health as natural microbes are to human health.
Soil is naturally made up of inorganic substances such as minerals and other materials, and should contain not only bacteria, but organic plant material worked back into the soil to help feed the bacteria and provide more nutrients for plant growth.
Soil Life adds these microbes, in a heightened state of activity, thereby providing optimum growing conditions for yard, garden or farm.

 What Makes Soil Tick
The processes that take place within the soil are, for the most part, dependent first upon the activities of living organisms; and hence, the existence of higher plants depends on the activities of the soil microbes.
As organic matter returned to the soil is digested by microbes the resulting cellular material is mixed with the living and dead bodies of bacteria, fungi, actinomycetes and other microscopic forms of life, together with certain excretory materials produced during their life cycles to form a dynamic, everchanging, organic material called HUMUS.
Multiply this by the number of spoonfuls of soil in an acre and you have figures that are astronomical.

SOIL LIFE REDUCES SOIL EROSION Gypsum Soil Life significantly reduces soil erosion and runoff on cultivated soils by maintaining larger aggregates in the soil structure.
The result is soil pH is lowered; soil aggregation improves and a crumbly, friable soil structure is restored, improving most vegetable and orchard crops.

 Hydric soil - Wikipedia, the free encyclopedia
A hydric soil is a soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part.
Soils with these unique properties are called hydric soils, and although they may occupy a relatively small portion of the landscape, they maintain important functions in the environment.
First, a soil that is artificially drained or protected (ditches, levees, etc.) is a hydric soil if the soil in its undisturbed state meets the definition of a hydric soil.
