Climate soil influence

Biomass Redistribution Associated with Deforestation and Fire. The influence of deforestation on biogeochemical cycles is dependent upon a number of factors associated with the unique characteristics of the ecosystem (climate, soils, topography, etc), the quantity of the total nutrient pool stored in aboveground biomass (Table II), and the level of disturbance (i.e. the degree of canopy removal, soil disturbance, and the quantity of wood or other forest products exported from the site). The quantity of biomass consumed by one or more slash fires following deforestation can also dramatically increase nutrient losses, influence post fire plant succession, and hence, postfire biogeochemical cycles. 

The obtained results allow us to advance with the basic assumption the north sector, subject to anthropogenic influence, it showed a carbon stock 23% lower than the south sector, which had less accessibility and a better state of conservation (Table 4). These differences were statistically significant (H = 11.20, p < 0.001) only for the AGB stratum, but not for the other strata studied nor for the total carbon stock. Under similar conditions of climate, soil, geomorphology, altitude, and latitude, the human influence could explain these differences, as the AGB stratum is the easiest to appropriate by humans [10,17,19, 21]. The AGB make the largest contribution in both sectors to the carbon stock (53, 55%), followed by SOC (28-31%) and finally BGB (8-10%) depending on the sector analyzed (Figure 3).

Protein based assays are influenced by the relative amount of protein in the cells, the so-called expression level. Expression of a specific protein varies according to different parameters, such as climate, soil, drought conditions, etc. If the expression level in a given sample is different from the expression level of the materials used as calibrators, additional uncertainty will impact the result expressed in mass fractions. While again, for individual and intact kernels other analytical approaches (pooled sampling procedures from GIPSA, see above) are possible that would not be affected by this phenomenon, this would not be applicable for processed samples. 

Topography The location of a soil in a landscape can affect how the climatic processes influence it. Soils at the bottom of a hill will get more water than soils on the slopes, and soils on the slopes that directly face the sun will be drier than soils on slopes that do not.

Many organic farmers all over the world face similar technical, economic and social problems. These are identified in the following section. However, answers to these questions depend considerably on where the organic farmer is located. The geographical location of a farmer is important because soil and climate differences influence input requirements, yields and total farm production capacity. Different policy approaches are then discussed, looking at the impact of policies on those producers for whom they are beneficial and those organic farmers in other countries that feel the consequences of those policies.

Except for zones below the level of permanent ground water where the environment is water-saturated, and for zones of dry surface sand, continual variation may be expected to occur in the water content of soils. This is usually dependent on rainfall, snow, flooding and such climatic influences, though irrigation practices in many agricultural areas influence water content and hence the corrosion rates.

In developing and applying the erosional-depositional system, careful consideration was given to the environmental factors which influence the potential for erosion, transport and deposition climate, topography, geology and soils, as well as human activity.
