What important agricultural technology assists in maintaining land efficiency?

GPS systems are crucial in modern agriculture for enhancing land efficiency. They enable farmers to accurately map and analyze their fields, optimizing planting, fertilization, and harvesting processes. By utilizing GPS technology, farmers can implement precision agriculture practices, which involve precisely applying inputs like seeds, water, and fertilizers only where and when they are needed. This leads to reduced resource waste and improved crop yields.

The other technologies listed, while beneficial in their own ways, do not primarily focus on land efficiency. Fertilizers improve plant nutrition but require management to prevent overuse. Hybrid seeds can enhance crop resilience and yield but do not directly address land management practices. Greenhouses are excellent for controlled environments but pertain more to plant growth conditions than to maximizing land efficiency on a broader scale.
