How does topography affect soil formation?
Topography has a strong influence on soil development. Soils on the side of hills tend to be shallow, due to erosional losses. Soils on the tops of hills tend to be deep, but lighter in color, due to downward leaching losses.
How does the terrain of a country affect agriculture?
How does terrain affect agriculture? Most crops are grown on land with shallow slope where the temperature, precipitation, and soils are favorable. In areas that are too steep, wet, or dry, landscapes have been modified to allow cultivation. You might be interested: Question: How Climate Change Affects Agriculture?
What is the meaning of topography in agriculture?
Topography—that is, the surface of the soil and its relation to other areas—influences efficiency of operation. In modern mechanized farming, large, relatively level fields allow for lower operating costs. Power equipment may be used to modify topography, but the cost of such land renovation may…
How does topography affect?
The topography of an area can influence the weather and climate. Topography is the relief of an area. If an area is close to a body of water it tends to make milder climates. Mountainous areas tend to have more extreme weather because it acts as a barrier to air movements and moisture.
How does geography affect agriculture?
Physical geography features (access to water, climate, soil types, landforms) influence how people farm in a region. Irrigation, terrace farming, deforestation, desertification, and the drainage of wetlands have occurred as farmers try to increase production to feed an ever-growing human population.
Does topography of the soil affect the growth of the plants?
Topography affects soil fertility with increasing fertility from ridge to valleys, because of soil erosion processes and matter transport, Individual soil fertility variables are explained by terrain attributes, and. Tree growth is positively influenced by soil fertility, and thus also by terrain attributes.
How does topography affect vegetation?
Elevation exerted the strongest influence on vegetation, followed by slope and wetness. Topography generally affected all vegetation measures and exhibited the strongest local relationships with the main species-compositional gradient, the main functional gradient and the plant’s average soil moisture preference.
Which topography is suitable for agriculture?
Answer: Loess plateau region is the largest loess area in the world, soil and water loss and degradation of ecological environment was serious in the past years. Middle and lower Yangtze region has favorable conditions for agriculture, utilization of cropland is high in this area.
How important is the topography of a site affects the production?
Topography is one of the most obvious causes of variation found in field crops both for its direct effect on micro-climate and for related soil fac- tors such as soil temperature, which influences germination, tiller production and crop growth.
What factors affect agriculture?
Different factors which influence agriculture are soil, climate, monsoon, irrigation facilities, availability or adoption of different technology.
What are the physical factors that affect the agriculture?
Physical factors: Terrain, topography, climate, and soil. Institutional Factors: Land tenure, land tenancy, size of the landholdings, size of fields, and land reforms. Infrastructural factors: Irrigation, electricity, roads, credit and marketing, storage, facilities, crop insurance, and research.
How does topography affect the soil?
Topography – Slope and aspect affect the moisture and temperature of soil. Steep slopes facing the sun are warmer. Steep soils may be eroded and lose their topsoil as they form. Thus, they may be thinner than the more nearly level soils that receive deposits from areas upslope.
How does topography affect land use?
The research indicated that topography factors, such as elevation, slope and aspect influencing land use pattern respectively and differently. As the increasing of altitude, land use types diversity index declined but with the patch aggregation degree increasing.
Why is topography important to plants?
The altitude or elevation of the land with respect to the level of the sea surface influences plant growth and development primarily through the temperature effects. The relationship of this abiotic factor to temperature is like that of distance from the equator to the arctic poles.
Why is the topography of the Earth changing?
In this lesson, we will learn about some of the amazing changes that occur on Earth due to the processes of weathering, erosion, and deposition. Ask a Question.
What is the position of both natural and artificial features and structures in an area?
Topography and Agriculture: Topography is the position or arrangement of both natural and artificial/human-made features and structures in an area. When shown on a map, it depicts these features and structures along with geographical elevation information.
How does topography affect agriculture?
Topography affects agriculture as it relates to soil erosion, difficulty of tillage and poor transportation facilities. Mechanization of agriculture depends entirely on the topography of land. On rough, hilly lands, the use of agricultural machinery is impossible.
How do social factors affect agriculture?
These factors are more effective in tribal cultures. Another way in which social factors can affect agriculture is in the ownership and inheritance of land. In many parts of the world the land of a father is divided between his children.
What are some examples of man’s efforts to change the landscape?
For example, man carries water to land where there is little rain, or supplies fertilisers to soil that are deficient in plant food. If necessary, he will adapt his agriculture to conditions that he cannot overcome.
Why is mechanised farming capital intensive?
The occidental farmer has to invest large amount of capital in agriculture because he has to buy agricultural machinery and chemical fertilizers.
What are the factors that determine the growth of agriculture?
Growth and development of agriculture is always directed and determined by physical, economic, social and political factors . In fact, geographical factors play a vital role in agricultural development, in spite of the technological and scientific development.
How is agriculture controlled?
All forms of agriculture are controlled largely by temperature. Areas deficient in heat are deficient in agriculture. For that is one element of climate that man has not been able to create at economic costs on a large scale.
What is intensive agriculture?
Labour supply determines the character of agriculture. Intensive agriculture is essentially labour-intensive and exemplifies the human pressure on land. Agriculture requires skilled labour that can appreciate the subtle relations of seasons and soils with crops and adopt the requisite cultural practices.
What are the factors that affect agriculture?
Climatic factors such as light, water, and rainfall, temperature, air, relative humidity and wind also affect farming in various ways. Just like other abiotic elements of environmental factors such as soil and topography, they influence how crops grow and develop.
What are the physical factors that affect farming?
Topography, soil, and climate are the major physical factors affecting farming. Topography/Relief – Topography relates to how difficult it is to till the land, soil erosion, and poor transportation networks and facilities. Agriculture can be mechanized depending on the topography of land to be used.
What is farming in the Neolithic period?
Farming is the practice of keeping animals and growing crops for raw materials and food. It is an important aspect of agriculture. Started centuries ago, agriculture is as old mankind, but nobody knows its exact age. Farming in the early century gave rise to the Neolithic Revolution.
Why are farmers encouraged to make sure there is an oversupply of a few types of crops?
It also ensures consumers have access to affordably-priced food products processed from the commodity crops. Farmers are also encouraged to make sure there is an oversupply of a few types of crops. Such crops are required to generate money for growing processed foods despite the prevailing conditions on the market.
What are the main factors that influence the price of commodity crops?
Commodity Prices – Weather, investor speculation and demand for non-food (such as biofuels) and food crops influence the price of main commodity crops such as soy and corn. Commodity crops earn farmers losses or profits based on the prevailing price of output that industrial buyers are willing to pay.
Why is farming so competitive?
The farming environment today is economically complex and competitive. It allows farmers worldwide to choose what to grow from what’s produced globally. On the other hand, governments offer financial incentives to farmers on specific types of crops. Most farmers in America are affected by weather and economic factors.
What temperature do crops need?
Crops require a general temperature range of 0 to 50 degrees Celsius. Different crops have varying optimal or favourable temperature range during the night or day for growth and optimal yields. Temperature rise increases chemical reaction rates and enzyme activity in crops.
Abstract
Quantitative knowledge of the factors and interactions affecting yield is essential for site-specific crop management. One of the factors that frequently affects yield is topography.
Introduction
Quantitative knowledge of the factors and interactions affecting yield is essential for site-specific crop management. It is commonly known that topography is one of the main factors affecting yield.
Materials and methods
The experimental data for this study were obtained from our experimental field of 11.5 ha in Prague—Ruzyne (50°05′ N, 14°18′ E), Czech Republic. The soil of this field is a Haplic Luvisol. The average precipitation is 526 mm per year and the average temperature is 7.9°C.
Results and discussion
Summary statistics of elevation are given in Table 2. The two sets of elevation data were compared with a t -test to determine whether they are significantly different.
Conclusions
The results showed that a combine harvester yield monitor can be used as a source of topographic data. The DEM, SM and FAM can be derived from these data with adequate precision using commonly used GIS software packages. These models can be used for comparison with other characteristics such as yield and soil properties.

Abstract
Information on soil properties and distribution is critical for making decisions with regard to crop production and mitigating land degradations. A reasonable way of deriving the information is using proxy environmental characteristics that have demonstrated relationships with soil properties.
1. Introduction
Understanding the distribution and properties of soils is necessary to planning and implementing sustainable land use and/or rehabilitation of degraded lands ( Ali et al., 2010 ).
4. Conclusions
Soils of the Ele watershed, southern Ethiopia have shown dynamics in the distribution of the soils and site characteristics, which were conditioned by landscape features. Accordingly, first topography is found as the major landscape feature controlling the development and characteristics of the soils of the Ele watershed, southern Ethiopia.
