ABSTRACT: Environmental assessment of agricultural production systems is an increasing concern within the international community. When evaluation involves biodiversity indicators, as richness or diversity in certain taxa or their roles in ecosystems, the participation of specialists is required to identify, classify and interpret diversity at the level of species, communities and ecosystems. Due to costs and time demand, this can be an important obstacle when a widespread use of these assessments is needed to contribute to policy making and evaluation, field
management decision-making or implementation of a specific technology. We developed a new index that combines different environmental characteristics which can be evaluated qualitatively and quantitatively with a basic training, can be implemented quickly and each index component is directly associated with key aspects for the assessment of ecosystem capacity to sustain wildlife and ecosystem services. The Ecosystem Integrity Index (EII) evaluates the status of a specific ecosystem under agricultural use, referred to an optimal condition that must be established for the ecoregion. Its application involves a qualitative and quantitative visual evaluation considering four components: vegetation structure, plant species, soil and riparian areas. Each component is valued on a 0?5 scale, where 5 is the best possible condition. EII is a simple and robust tool for evaluating and monitoring integrity of groecosystems and the primary validation demonstrates good correlation with other environmental variables such as wildlife diversity and soil organic carbon.

ABSTRACT - In Campos grasslands, the production of forage and its variability are driven by the amount of rainfall. In this context, stockpiling forage from spring to summer is a useful tool to maintain the feed supply for livestock, but so far it has not been developed due to the lack of information for farmers decision-making. In this paper we evaluated the response of pasture production to spring grazing deferment in a shallow basaltic grassland in 12 combinations of lime (0 and 1500 kg ha-1 of CaMg(CO3)2), phosphorus (0 and 90 kg ha-1 of P2O5) and nitrogen (0, 75, 150, and 300 kg ha-1 of N, except in the upper two N levels that were evaluated only with lime) addition.Forage accumulation, sward height and nitrogen nutrition index (NNI) were evaluated every 15 days during 75 days. Both sward height and available forage mass increased linearly with the deferment time. The lime appli-cation did not affect the forage accumulation rate, while the single nitrogen and phosphorus addition only showed a slight positive effect, however the combined addition of N-P fertilization tripled the forage production. Nitrogen fertilization improved the NNI and was further enhanced by the combined application of N and P. Our results suggest that the capacity of shallow basaltic grasslands to accumulate deferred forage is co-limited by N and P availability.

RESUMEN - En los campos naturales del bioma Campos, la producción forrajera y su variabilidad están determinadas prin-cipalmente por la cantidad de lluvias. En este contexto, la reserva de forraje en pie en primavera es una estra-tegia para mantener la oferta de alimento para los animales en los veranos, pero falta información para que los productores pueden tomar las decisiones de manejo. El presente trabajo evaluó la respuesta de la producción de un campo natural de basalto superficial al diferimiento primaveral en 12 tratamientos que combinaron: el encalado (0 y 1500 kg ha-1 of CaMg(CO3)2) con dos dosis de fertilización fosfatada (0 y 90 kg ha-1 de P2O5) y cuatro niveles de nitrógeno (0, 75, 150, y 300 kg ha-1 de N, en los dos niveles superiores se evaluaron solo con encalado). La producción de forraje, la altura de dosel y el índice de nutrición nitrogenada (INN) fueron evalua-dos cada 15 días durante 75 días. La altura del dosel y la disponibilidad de forraje aumentaron linealmente con el tiempo de diferimiento. La producción de forraje no fue afectada por el encalado, por su parte existió una discreta respuesta cuando N y P se aplicaron aislados, en cambio, la fertilización conjunta con N y P triplicó la cantidad de forraje acumulado. La aplicación de nitrógeno aumentó el INN, dicha respuesta fue más importante cuando el N se aplicó combinado con P. El presente trabajo evidenció que la capacidad de diferir forraje prima-veral en campos naturales de basalto superficial, está colimitada por la disponibilidad N y P.

RESUMO - Nos campos naturais do bioma Campos, a produção forrageira e sua variabilidade estão determinadas princi-palmente pela quantidade de chuvas. Neste contexto, a reserva de forragem em pé na primavera é uma estra-tégia para manter a oferta de alimento para os animais no verão, mas falta informação para que os produtores possam tomar as decisões de manejo. O presente trabalho avaliou a resposta produtiva de um campo natural de basalto superficial ao diferimento primaveral em 12 tratamentos que combinaram: a calagem (0 e 1500 kg ha-1 de CaMg(CO3)2.) com duas doses de fertilização fosfatada (0 e 90 kg ha-1 de P2O5) e quatro níveis de nitrogênio (0, 75, 150, e 300 kg ha-1 de N, os dois níveis superiores foram avaliados somente com calagem). A produção de forragem, a altura de dossel e o índice de nutrição nitrogenada (INN) foram avaliados a cada 15 dias durante 75 dias. A altura do dossel e a disponibilidade de forragem aumentaram linearmente como tempo de diferimento. A produção de forragem não foi afetada pela calagem, e apresentou uma discreta resposta quando N e P foram aplicados de maneira isolada, em contrapartida a fertilização conjunta de N e P triplicou a quantidade de forragem acumulada. A aplicação de nitrogênio aumentou o INN, resposta que foi mais impor-tante quando o N foi aplicado combinado com P. O presente trabalho evidenciou que la capacidade de diferir forragem primaveral em campos naturais de basalto superficial, está co-limitada pela disponibilidade de N y P.
