Increased temperature, changed precipitation conditions and increased CO2 content in the atmosphere are the major climatic factors affecting crop production. … The amount and availability of water stored in the soil will be affected by changes in both the precipitation and seasonal and annual evapotranspiration regimes.
What are the climatic factors that affect crop production?
Nigeria is still practicing rain fed agriculture which renders her vulnerable to the adverse effects of climate change. Extreme climatic events such as flooding, extreme heat, and drought has led to soil degradation which results in low crop yields.
How climatic factors affect cropping systems?
Crop production is highly sensitive to climate. It is affected by long-term trends in average rainfall and temperature, interannual climate variability, shocks during specific phenologicalii stages, and extreme weather events (IPCC, 2012). … As climate changes, crop production strategies must change too.
What are the soil factors affecting cropping systems?
The four most important factors that influence crop yield are soil fertility, availability of water, climate, and diseases or pests.
What are the 3 factors affecting crop production?
These factors are grouped in three basic categories known as technological (agricultural practices, managerial decision, etc.), biological (diseases, insects, pests, weeds) and environmental (climatic condition, soil fertility, topography, water quality, etc.).
What are soil factors?
Soil Forming Factors
- Parent material. Few soils weather directly from the underlying rocks. …
- Climate. Soils vary, depending on the climate. …
- Topography. Slope and aspect affect the moisture and temperature of soil. …
- Biological factors. Plants, animals, micro-organisms, and humans affect soil formation. …
How does soil and climate greatly affect the development of vegetable crops?
Moisture. The amount and annual distribution of rainfall in a region, especially during certain periods of development, affects local crops. … Extremely wet soil also retards root growth by restricting aeration. Atmospheric humidity, the moisture content of the air, also contributes moisture.
How does soil affect agricultural yields?
Soil provides the structural support to plants used in agriculture and is also their source of water and nutrients. … Processes such as leaching, weathering and microbial activity combine to make a whole range of different soil types. Each type has particular strengths and weaknesses for agricultural production.
How soil fertility affect crop production?
Crops need nutrients just like people do. A fertile soil will contain all the major nutrients for basic plant nutrition (e.g., nitrogen, phosphorus, and potassium), as well as other nutrients needed in smaller quantities (e.g., calcium, magnesium, sulfur, iron, zinc, copper, boron, molybdenum, nickel).
What are the 5 factors affecting plant growth?
Environmental factors like temperature, light, water, nutrients, and soil affect plant growth from their germination to blooming.
What are the factors affecting crop production in the Philippines?
These are the environment (soil, topography, and climate), socio-economic (tenure and capital) and technical (available technology and management requirements) factors that could either be within or beyond the control of the farmers (PCARRD, 1993).
