Answer:

A. Overtillage can increase the rate of humus decomposition

Explanation:

We refer to humus as any material of an organic nature that undergoes soil degradation. Humus is very important for agriculture because it has high nutrient levels that it provides to all crops. This causes more crop productivity, increases the producer's profit and increases the number of food available to the population.

Humus is a difficult to decompose material, but under favorable conditions it can decompose quite easily. Due to the presence of large amount of burnt organic matter in the soil, it is sometimes difficult to increase the humus content, so the exhaustion of this organic matter is caused by over tillage, especially in regions of tropical and sub-tropical climate, poorly managed. farmer protection and unprotected effects of erosion.

Write a 225 word report on why each of the factors (R, K, L, S, C, and P) are important factors needed to determine the amount o

Lostsunrise [7]

Answer:

The R, K, L, S, C, and P factors are -

R - the rainfall erosivity factor,

K - soil erodibility factor

L- the topographic factor derived from slope length

S -the topographic factor derived from slope gradient

C- the cover and management factor

P - the erosion control practice factor

Explanation:

The R, K, L, S, C, and P factors are -

R - the rainfall erosivity factor, which depends on geographic location. The greater is the intensity and duration of the rainfall, the higher will bethe erosion potential.

K - soil erodibility factor, K signifies the soil loss in tonnes/hectare (tons/acre) for any agricultural land that is cultivated and has a slope length (assumed) of 22.13 meters and slope steepness of 9%. K represents the susceptibility of a soil particle to be easily detached from the surface and carried away by rainfall and runoff. The greater is the value of K , the greater is the erodibility of the soil particles.

L- the topographic factor derived from slope length, It signifies the extent of soil being carried away when slope lengths is greater than an assumed slope length of 22.13 meters. The longer the slope , the higher is the rate of erosion.

S -the topographic factor derived from slope gradient, It signifies the extent of soil being carried away when slope steepness is greater than an assumed slope steepness of 9%. The steeper the slope , the higher is the rate of erosion.

C- the cover and management factor, It states how effective soil and crop management systems is in terms of preventing soil loss. It is a ratio of soil loss from land under a specific crop and management system to corresponding loss from continuously fallow and tilled land. The higher the C value, the lower is the management process quality to prevent soil erosion

P - the erosion control practice factor, It represents the after effects of practices pertaining to reduce erosion by reducing the amount and rate of the water runoff. The lower the P value, the better is the effects of practices pertaining to reduce erosion

Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary produ

Katen [24]

Answer:

The answer is C.

Explanation:

Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.

The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.

Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.

Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.

Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.

I hope this answer helps.
