Answer:
Climate, land relief, soil and vegetation are the main factors which influence agricultural activity.
Climate
The growth of plants depends on the temperature and humidity of the land and the amount of light it receives.
We can't practice agriculture in areas with extreme temperatures
below 0ºC
above 45ºC
We also cant grow plants in areas of severe drought.
Land relief
Farmers prefer to cultivate crops on flat land
plains
valley bottoms
It is harder to cultivate in mountainous areas:
machines can't be used for soil preparation or harvest
terraces must be cut into the hillside
low temperatures prevent cultivation in high altitudes
Livestock farming and forestry adapt better to mountainous terrain.
The relief will also affect the available water resources.
Soil
The soil is the result of the decomposition of bedrock. Soils are made up of a series of layers called horizons.
Soil provides the nutrients necessary for plants to grow.
The fertility of the soil depends on various factors:
Depth
Deeps soils have thick evolved layers
Found in valleys and plains
Fertile soils
Thin soils are made up of external layers
found on the slopes of mountains and high plateaus
Not very fertile
Texture (influences water retention)
Sand, silt, clay
Acidity or Alkalinity
The acidity of soils is measured by their pH.
The PH of pure water is 7 (neutral)
When a soil's pH value is lower than 7 it is acidic
When its pH value is higher than 7 is is basic or alkaline
Soils which are too acidic or alkaline are not very fertile
Explanation:
Like me ......follow me......for more answer......
The factors that influence crop yield are:
1. soil fertility
2. availability of water
3.climate
4. diseases or pests
