The pasture manager uses the grazing animal and the timing and intensity of pasture defoliation to manage the health and vigor of plants in the pasture community.

The goal of good pasture management is the long-term health and productivity of the pasture, so it provides an optimal quantity of high-quality forage that meets the nutritional needs.

Export of SS and nutrients (except DRP) from the pasture catchment was 4- to fold higher during the winters of and than winter when rainfall was half the normal level. Streams draining native forest had lower tem-perature, sediment, and nutrient.

Changes in nutrient and hydrological cycles caused by land disturbance typically lead to detrimental changes to ecosystems.

This study utilized a paired, small-catchment approach to examine the effect of deforestation on soils and streams of the tropical Osa Peninsula, Costa Rica. The first catchment had been cleared for pasture and the second consisted of undisturbed tropical wet forest.

The ratio of C isotopes changes little as carbon moves through food webs and, therefore, typically can be used to evaluate the ultimate sources of carbon for an organism when the isotopic signature of the sources are different (Collier et al. δ 13 C and δ 15 N signatures for in-stream algae, terrestrial leaves, and stream invertebrates.

We examined responses of soil nutrients, plant tissue nutrients, biomass of live, standing dead and litter, and plant species composition to experimental annual prescribed fire applied during different seasons (wet season vs. dry season), and nutrient additions (N, P and N + P) over 9 years. The long-term monitoring program initiated as part of the Luquillo LTER was critical to the evaluation of immediate and subsequent effects of Hurricane Hugo, which struck Puerto Rico in The occurrence of a hurricane soon after the initiation of the LTER program provides an opportunity to study the long-term dynamics of a tropical forest.

The term soil fertility has ancient origins and has been consistently used over centuries to refer to the capability of soil to support plant production in agricultural contexts. Historically, the most common use of soil fertility has focused on provisioning mineral nutrients for plant growth (e.g.

Foth and Ellis, ; Tisdale et al., ).An emphasis on fertilizer-based nutrient amendment. In a long-term experiment on rice–wheat cropping system at Faizabad in India, Kumar and Yadav () found that 20 years after continuously applying different combinations of N, P, and K rates to both the crops, the highest rate of yield decline in wheat was found when kg ha − 1 N was applied with no P and K.

The lowest rate of decline was observed when N, P, and K were applied at Stream and river ecosystems are dependent on energetic inputs from their watersheds and thus shifts in land use from forest cover to agriculture will affect stream community composition and function.

The disruption of forest-aquatic linkages alters the organic matter resources in agricultural streams. Dissolved organic matter (DOM) is the dominant form of organic matter in aquatic ecosystems.
