Key Factors and Types of Farming Practices Worldwide
Factors Influencing Agricultural Production
Understanding the conditions necessary for successful farming involves analyzing several key factors:
Climatic Conditions for Crop Development
Every culture needs specific climatic conditions, temperature, and humidity levels to develop successfully.
Topography and Agricultural Location
Agricultural activities are located on plains and slopes. Steep slopes often present difficulties for work and the use of heavy machinery.
Soil Characteristics and Crop Success
Soil quality significantly impacts the success of crops. Not all soils are suitable for growth. Success depends on the soil's texture, which influences water retention, and its acidity conditions, which affect fertility.
Physical Factors and Technological Mitigation
Physical factors (such as a dry season) are very important when human economic and technical means are limited. However, highly technified companies can easily overcome some of these conditions (e.g., using artificial soil).
Types of Traditional Agriculture
Shifting Cultivation (Slash-and-Burn)
This method is practiced in equatorial Africa, South America, and Asia. It involves clearing areas of forest or savannas by burning. The clean ash is used as fertilizer. The soil is tilled, and seeds are planted. The land is productive for only three or four years before the soil depletes and erodes rapidly. Consequently, farmers leave the land for other areas and start the process anew.
Extensive Dryland Agriculture and Triennial Rotation
This system is based on the association of agricultural and livestock activities, utilizing the fertilizer provided by the animals on permanent farmland. The plots are typically divided into three separate sections:
- One section is left fallow and dedicated to grazing livestock.
- The other two sections are used for the cultivation of groundnuts and millet.
Plots follow triennial rotation: a tillage system that involves dividing the parcel into three parts. This rotation is related to fallow periods (leaving a part unseeded), the planting of legumes (which fix nitrogen in the soil), and other cereals.
Intensive Irrigated Rice Agriculture
Practiced where rains are abundant, often due to monsoons. Rice is cultivated because it is a plant that does not significantly impoverish the soil and can feed many people. It is highly intensive, often yielding a summer harvest and a second rice crop in winter.
Commercial Market Agriculture
Commercial agriculture is practiced in regions like North America, Western Europe, Japan, Australia, New Zealand, and many regions of Argentina.
Objectives: Increase sales and reduce costs, achieved through:
Mechanization of the Field
The use of machinery saves manpower, increases production, and lowers prices for agricultural products.
Specialization of Agrarian Production
Focusing production quantity to produce more and ensure better marketing.
Rapid Marketing and Distribution
Accelerating product commercialization within the same country and between different countries by using adequate transport methods.
Definition of Market Agriculture
Market agriculture is defined by the orientation of its products toward sale.
Mediterranean Agriculture
This is traditional agriculture that, in order to enter the market economy, has had to adapt to new techniques.
Subsistence Agriculture
Subsistence agriculture is focused on producing food primarily for the consumption of the farmer and their family, rather than for sale in the market.
