Cultivation
Overview
Cultivation (耕作) refers to a series of agricultural activities from tilling and preparing the land to planting, growing, and harvesting crops. It was a core technology that enabled sedentary life and surplus production as humanity passed through the Neolithic Revolution, and today it still functions as a foundational industry supporting food security and local economies. Cultivation is not mere labor but a complex system interwoven with soil, water, climate, seeds, technology, and institutions, and its methods greatly affect productivity and environmental impact.

Definition and Scope of Cultivation
In the narrow sense, cultivation refers to the process of plowing a field (tillage) and then sowing, fertilizing, irrigating, weeding, and controlling pests before harvesting. In a broad sense, it includes rice farming, dry-field farming, orchards, greenhouse horticulture, grassland establishment, and forestry cultivation. By contrast, it is distinguished from primary-industry activities such as livestock raising or fishing that do not directly till the soil.
Historical Development
Cultivation is known to have begun around 10,000 years ago in the Fertile Crescent with the growing of wheat and barley. The invention of the plow and irrigation canals greatly raised productivity, while three-field rotation and crop-rotation systems became established as wisdom for maintaining soil fertility. After the Industrial Revolution, chemical fertilizers, tractors, and plant-breeding technologies combined to cause an explosive increase in yields per unit area, which supported population growth and urbanization.
Types of Cultivation Methods
- Traditional cultivation: Usually centered on human and animal power, small-scale subsistence-oriented, and based on mixed cropping of various crops.
- Conventional farming: A method that maximizes yields through active use of chemical fertilizers and pesticides.
- Organic farming: Excludes synthetic pesticides and chemical fertilizers and uses compost, green manure, and biological pest control.
- Conservation cultivation: Reduces soil disturbance through minimum tillage or no-till and covers the ground with straw or cover crops.
- Precision agriculture: Manages field-level variability using satellite navigation, sensors, and drones to optimize inputs.
Technological Elements and Soil Management
Tillage changes soil aggregate structure and helps root development, but excessive tillage causes loss of organic matter and erosion. Therefore, crop rotation, green-manure crops, combinations of deep and shallow plowing, and drainage and irrigation design are important. It is standard practice to periodically test soil acidity (pH), salinity concentration, and available phosphorus and potassium levels to determine fertilizer application rates. In water management, drip irrigation, surface irrigation, and water-saving irrigation for flooded rice paddies are selected according to local conditions.
Socioeconomic Significance
Cultivation is directly linked to farm household income, agricultural product prices, the trade balance, and rural employment. In regions with a high share of smallholders, the small scale of cultivation is cited as a factor hindering productivity, and organizational approaches such as land leasing, joint farming, and cooperatives are discussed as alternatives. In addition, farmland conversion and urban expansion create the structural problem of reducing high-quality farmland.
Latest Trends
The biggest changes in cultivation in 2024–2025 are digital transformation and climate response. First, as smart farms and precision agriculture spread, soil moisture sensors, weather data, satellite imagery, and AI-based pest and disease prediction are becoming commonplace. Second, so-called 'carbon farming,' which stores carbon in soil using no-till, cover crops, biochar, and other methods, is attracting attention as a means of reducing greenhouse gases. Third, as abnormal high temperatures, droughts, and heavy downpours become more frequent due to climate change, the redesign of drought-tolerant and heat-tolerant varieties, water-saving irrigation, and paddy water management methods is underway. Fourth, vertical farms and plant factories have entered the commercialization stage, centered on leafy vegetables and herbs, and small-scale cultivation models near cities are also increasing. Fifth, in response to the aging rural population and labor shortages, autonomous tractors, agricultural drones, and robotic harvesters have moved beyond demonstration and entered the early stage of deployment. In addition, as grain price volatility and supply chain risks grow, countries are strengthening the maintenance of cultivation foundations, stockpiling, and contract farming from the perspective of food security.
