Final answer:
The statement that a tractor is a modern tool of agriculture is justified by the role tractors play in increasing farming efficiency and productivity, allowing for the cultivation of larger fields, and contributing to the transition from subsistence to commercial farming post-Industrial Revolution.
Step-by-step explanation:
“A tractor is a modern tool of agriculture.” This statement can be justified by examining the transformation of agricultural practices over time and the role of modern mechanization in increasing efficiency and productivity on farms. Initially, agriculture started with simple tools like the pointed stick and evolved with the use of animals to pull plows. The Industrial Revolution brought significant changes, introducing gasoline-powered farm tools such as tractors, which revolutionized farming methods. With the advent of machinery like seed drills, threshers, and combine harvesters, farmers could move beyond subsistence farming toward planting large fields of a single crop, thus maximizing profits.
The development of mechanized equipment like tractors allowed for the expansion of the 3-field rotation system and the cultivation of heavier soils with greater efficiencies. Modern tractors are essential for tasks such as tilling, planting, and harvesting, leading to increased crop yields and lower costs. They also facilitate the implementation of innovative farming techniques, including precision agriculture, which leverages GPS and data analytics for more efficient farming practices. Thus, a tractor is indeed a modern tool that is integral to contemporary agriculture, contributing to global food security and sustainability.
