Exploring global changes in nitrogen and phosphorus cycles in agriculture induced by livestock production over the 1900-2050 period.

Crop-livestock manufacturing methods are the biggest reason for human alteration of the worldwide nitrogen (N) and phosphorus (P) cycles. Our complete spatially express stock of N and P budgets in livestock and crop manufacturing methods reveals that to start with of the 20th century, nutrient budgets have been both balanced or surpluses have been small; between 1900 and 1950, world soil N surplus nearly doubled to 36 trillion grams (Tg) · y(-1) and P surplus elevated by an element of eight to 2 Tg · y(-1). Between 1950 and 2000, the […]
