Resumo: | Inadequate management practices are the main factors that can cause pasture degradation, and one of the key factors is to understand the nutrient cycling in pasture ecosystems. This review aimed to describe the cycling processes of important nutrients in pasture ecosystems (nitrogen, phosphorus, and potassium), analyzing the interactions of soil-plant-animal components. The use of forage legume species intercropped with grasses is a strategy to increase the nitrogen content in the soil, minimizing costs with nitrogen fertilization in pastures. Manure and plant residues are great organic sources of phosphorus and potassium but are also fundamental for supplying microminerals. Nitrogen losses in pastures are mainly caused by leaching, runoff, and volatilization. The addition of phosphorus to the soil must be performed carefully, as there is an increase in phosphorus losses with increasing accumulation in the soil. Phosphorus is often returned to the soil far from where it was used, so the stock transfer represents a loss in pasture ecosystems that can account for approximately 5% of the inputs of phosphate fertilizers. Potassium losses mostly occur by leaching and runoff. Improving management practices is essential for balanced nutrient cycling in pasture ecosystems. |

Nitrogen, phosphorus, and potassium cycling in pasture ecosystemsCiclagem de Nitrogênio, Fósforo e Potássio em Ecossistemas de PastagemInadequate management practices are the main factors that can cause pasture degradation, and one of the key factors is to understand the nutrient cycling in pasture ecosystems.

Esta revisão teve como objetivo descrever os processos de ciclagem de nutrientes importantes em ecossistemas de pastagem (nitrogênio, fósforo e potássio), analisando as interações entre os componentes solo-planta-animal. Verificou-se que o uso de espécies de leguminosas forrageiras consorciadas com gramíneas é uma estratégia para aumentar o teor de nitrogênio no solo, minimizando os custos com adubação nitrogenada em pastagens campestres. Estrume e resíduos vegetais são as principais fontes orgânicas de fósforo e potássio. As perdas de nitrogênio nas pastagens ocorrem principalmente por lixiviação, escoamento superficial e volatilização. A adição de fósforo ao solo deve ser feita com cautela, pois há um aumento nas perdas de fósforo com o aumento de seu acúmulo no solo. O fósforo é muitas vezes devolvido ao solo longe do local onde foi consumido, de modo que a transferência de estoque representa uma perda nos ecossistemas de pastagem que pode representar aproximadamente 5% das entradas de fertilizantes fosfatados. As perdas de potássio ocorrem principalmente por lixiviação e escoamento superficial. A melhoria das práticas de manejo é essencial para uma ciclagem equilibrada de nutrientes em ecossistemas de pastagem.
