Abstract	A estrategia implementada pelo governo para aumentar a cobertura florestal tem sido a punicao dos proprietarios que nao seguem a legislacao ambiental. As vantagens da presenca de floresta em areas agricolas sao raramente discutidas, como e o potencial que a floresta possui de fertilizar o solo ao seu redor. A influencia da borda florestal na fertilidade do solo em areas agricolas foi verificada em cinco fragmentos florestais da regiao de Londrina – Parana. O solo da regiao e originado de rochas basalticas, apresentando diferencas de acordo com a intensidade do intemperismo. O Latossolo Vermelho Distroferrico esta presente no planalto intemperizado, o Nitossolo Vermelho Distroferrico nas vertentes e pequena porcao de Neossolo Litolico nos locais mais elevados. Foi avaliada a fertilidade do solo, atraves de seus componentes; materia orgânica (MO), pH, acidez potencial, Ca, Mg, K e P, em intervalos de 5m ate a distância de 50m da borda florestal em direcao a area agricola. O conteudo de materia orgânica foi maior ate 10 m de distância da borda florestal, o que demonstra o efeito positivo de florestas na agricultura. Fragmentos florestais maiores mostraram maior influencia na quantidade de nutrientes do que fragmentos menores.
