===Humus=== | |||
<b>"It is difficult to define humus precisely because it is a very complex substance which is not fully understood." </b> <br> | |||
In soil science, humus (derived in 1790–1800 from the Latin humus for earth, ground[1]) denominates the fraction of soil organic matter that is amorphous and without the "cellular cake structure characteristic of plants, micro-organisms or animals".[2] Humus significantly affects the bulk density of soil and contributes to its retention of moisture and nutrients. | |||
In agriculture, "humus" sometimes also is used to describe mature or natural compost extracted from a woodland or other spontaneous source for use as a soil conditioner.[3] It is also used to describe a topsoil horizon that contains organic matter (humus type,[4] humus form,[5] humus profile).[6] | |||
Humus is the dark organic matter that forms in soil when dead plant and animal matter decays. Humus has many nutrients that improve the health of soil, nitrogen being the most important. The ratio of carbon to nitrogen (C:N) of humus is 10:1. <br> | |||

In biology, an organism (from Greek: ὀργανισμός, organismos) is any individual entity that exhibits the properties of life. It is a synonym for "life form".<br> | |||

The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from 6th century BC India and the 1st century BC book On Agriculture by Marcus Terentius Varro. Microbiology, the scientific study of microorganisms, began with their observation under the microscope in the 1670s by Antonie van Leeuwenhoek. | The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from 6th century BC India and the 1st century BC book On Agriculture by Marcus Terentius Varro.

===Soil microorganisms=== | |||
"Microbes can make nutrients and minerals in the soil available to plants, produce hormones that spur growth, stimulate the plant immune system and trigger or dampen stress responses. In general a more diverse soil microbiome results in fewer plant diseases and higher yield." <br> | |||
