Resumo: The State of Rio Grande do Sul, southem Brazil has 10 million hectares of native pastures and soils with high acidity and phosphorus deficiency, requiring liming and fertilization to improve productivity. An experiment was carried out at Centro de Pesquisas em Forrageiras, in São Gabriel county, Rio Grande do Sul, Brazil, aiming to study the residual effect of superficial liming and fertilization on dry matter yield of native pasture and on some soil chemical characteristics. A split-plot experimental design with randomized blocks and three replications was used. Treatments were limestone (zero, 4,3 and 8,6t.ha') with annual fertilization (45 kg.ha' de N, 110 kg.ha' de P2O5 e 60 kg.ha-' de K2O) and without fertilization and two depths (0-3cm and 3-6cm). The limestone was applied on February, 1994 and fertilizations were annual since February, 1994 until February, 1996. Soil and forage samples were collected by October, 1997. Fertilization showed a residual positive effect, increasing dry matter yield of native pasture. On the other hand, limestone application decreased exchangeable AI ¨3  and increased pH and  availability of soil Ca" and Mr.

No Centro de Pesquisa em Forrageiras da FEPAGRO, em São Gabriel, RS, foi desenvolvido este trabalho com o objetivo de avaliar o efeito residual da calagem e adubação superficiais na disponibilidade de forragem da pastagem nativa e em algumas características químicas do solo Argissolo vermelho eutrófico. O delineamento experimental utilizado foi o de parcelas subdivididas arranjadas em blocos casualizados, com três repetições. Os tratamentos foram: doses de calcário (zero, 4,3 e 8,6 t.ha'), com adubação anual (45 kg.ha' de N, 110 kg.ha-1de P2O5e 60 kg.ha-' de K2O) e sem adubação e duas profundidades (0-3cm e 3-6cm). O calcário foi aplicado em cobertura, em fevereiro de 1994 e as adubações, anualmente, de fevereiro de 1994 a fevereiro de 1996. As amostras de solo e de forragem foram coletadas em outubro de 1997. A adubação superficial apresentou efeito duradouro, pois, após 20 meses da última aplicação do adubo, havia maior disponibilidade de matéria seca da pastagem neste tratamento e maior teor de P no solo. A calagem reduziu o Al" e aumentou o 0-1 e a disponibilidade de Ca' e Mg" , na profundidade de zero a 3 cm.Departamento de Diagnóstico e Pesquisa Agropecuária.
