pastura

Pastura refers to land managed for forage production and grazing by livestock. It comprises grasses, legumes, and other herbaceous plants kept as a stand of forage rather than harvested crop. While the term is used in Spanish- and Portuguese-speaking contexts, its practical meaning varies by region, but generally denotes managed grassland used to feed animals such as cattle, sheep, and goats.

Pastures can be permanent, lasting several years, or temporary and rotated. They are usually dominated by grasses, with legumes such as clover or alfalfa included to improve nutrition and soil nitrogen. Species choice depends on climate, soil, and farming objectives.

Management influences productivity and sustainability. Key practices include stocking rate and grazing rotations, soil fertility management, weed control, and occasional reseeding or renovation. In many systems, irrigation or drainage, pasture rest periods, and mowing for quality forage are used to maintain regrowth and forage quality.

Benefits of pasture-based systems include lower feed costs, steady forage supply, and potential positive environmental effects like reduced erosion and improved soil structure. They also face challenges from drought, climate variability, pests, weed invasion, and soil degradation if grazing pressure exceeds recovery or fertility declines.

Globally, pastura is a central component of livestock production in temperate and tropical regions. Ongoing research seeks to improve species mixtures, resilience to drought, and nutrient balance to sustain production while protecting ecosystems.
