human agricultural interaction with the nitrogen cycle is primarily due to?
planting of leguminous crops
until 1850, natural bnf, cultivation-induced bnf (e.g., planting of leguminous crops), and incorporated organic matter were the only sources of n for agricultural production. near the turn of the century, nr from guano and sodium nitrate deposits was harvested and exported from the arid pacific islands and south american deserts. by the late 1920s, early industrial processes, albeit inefficient, were commonly used to produce nh. due to the efforts of fritz haber and carl bosch, the haber-bosch process became the largest source of nitrogenous fertilizer after the 1950s, and replaced bnf as the dominant source of nh production. from 1890 to 1990, anthropogenically created nr increased almost ninefold. during this time, the human population more than tripled, partly due to increased food production.
human impact on the nitrogen cycle
the nitrogen cycle is of particular interest to ecologists because nitrogen availability can affect the rate of key ecosystem processes, including primary production and decomposition. human activities such as fossil fuel combustion, use of artificial nitrogen fertilizers, and release of nitrogen in wastewater have dramatically altered the global nitrogen cycle. human modification of global nitrogen cycle can negatively affect the natural environment system and also human health.
