s = F(cl, p, r, t, o)
The science of soils may be an important subsection of the new website, as it will be regarded as an important discussion for the local application to apricot cultivation across many temperate climate regions.
The nature of the soil profile at any particular place on Earth depends on five main pedogenic factors. These are :
1. The past and present climate.
2. The physical and chemical characteristics of the parent material.
3. Relief and hydrology.
4. The length of time during which soil-forming processes have been active.
5. The ecosystem, including vegetation, fauna and the effects of human activities.
Dokuchaiev, a famous nineteenth-century Russian soil scientist, was the first to record the connection between the genesis of soil profiles and these five controlling factors. Later an American soil scientist, Hans Jenny (1941), expressed the relationship in his fundamental equation of soil formation :
s = F(cl, p, r, t, o)
where s = soil profile or property, cl = climate, p = parent material, r = relief, t = time, o = organisms, including humans.
Each location - whether of a home orchardist or the commercial orchard - will present a distinct succession of soil horizons reflecting the combined effects of a particular combination of these five genetic factors.
