A crop grown for its value as ground cover to reduce soil erosion, retain soil moisture, provide nitrogen for subsequent crops, control pests, improve soil texture, increase organic matter, or control erosion; also known as living mulch and green manure.

Nitrogen (N) pollution is shaped by multiple processes, the combined effects of which remain uncertain, particularly in the tropics. We use a global land biosphere model to analyze historical terrestrial-freshwater N budgets, considering the effects of anthropogenic N inputs, atmospheric CO2, land use, and climate. We estimate that globally, land currently sequesters 11 (10–13)% of annual N. Tropical Forage Plants: Development and Use covers the research and resulting pasture development in the tropics and subtropics, which has undergone dramatic changes in the past few decades. Providing a broad, global perspective, it serves as a comprehensive resource covering a wide range of subjects pertaining to forage and animal production in the tropics and subtropics including such. A second reason for doing this research in tropical forests is that deforestation is occurring rapidly in tropical regions (Houghton ), resulting in land uses, such as active and abandoned cattle pastures, where nitrogen availability and nitrogen oxide emissions may be altered relative to those of the primary forests that were replaced.

  Nitrogen is the most limiting nutrient in a majority of tropical and subtropical grassland ecosystems (Sollenberger et al., ). Stargrass is responsive to N fertilizer, with yields increasing from to Mg [] [] (d cutting interval) and from to Mg [] [] (d cutting interval) in Puerto Rico when N application was increased from 0 to.

The literature concerning the agronomic characteristics and nutritive value of the legume Lablab purpureus (Lab lab) is reviewed.   A whole new world has been opened up for the farmer to get a better understanding of the fascinating and important goings on in his/her soil, but these tests take work and thought to fully comprehend and apply. Nancy’s contribution here and the link she provides to Bellows review will be very helpful in this regard.

The objective of this study was to evaluate the efficiency of nitrogen utilization (ENU) and animal performance in cattle fed tropical grass pastures and receiving nitrogen supplementation, using.

While most graziers don’t utilise nitrogen in extensive pastures, there is an opportunity to fill feed gaps in winter by applying some nitrogen to boost growth. This trial tested three nitrogen rates starting with 30 kg/ha of nitrogen (65 kg/ha of urea), 60 kg/ha of nitrogen ( kg/ha of urea) and 92 kg/ha of nitrogen ( kg/ha of urea).

Davies and Skidmore edited a book, "Tropical Pastures," which presents the modern approach to tropical pastures. Now that reliable tropical legumes and grasses are available as well as knowledge of their fertilization, management, and productivity, considerable interest has been stimulated in the tropics in the use of.

We also expect that this review will help researchers and producers to understand the role of forage legumes in a pasture system and that there will be an increase in its utilization worldwide, especially in the tropics, where nitrogen is easily leached and lost from the pastures.

VOLGER, E. The tropical soil cannot support enough plant growth for grazing success. In order to grow enough forage for livestock, nutrients like nitrogen have to be added back into the soil. Four nitrogen fertilizer regimes were applied to irrigated, high density, annual clover pastures which had been oversown into a tropical pasture in April.

Pastures received no nitrogen fertilizer (control); nitrogen in autumn only; nitrogen in autumn and winter only; and nitrogen in autumn, winter and spring. The potential for selection is greater in tropical than in temperate pastures because of the large variation in nutritive value (nitrogen, digestibility, fibre and chemical composition) both within and between the leaf and stem components of tropical pasture swards.

The animal's ability to draw on body reserves for nutrients. Following a dry winter and early spring in legume growth in many perennial grass pastures (tropical and temperate species based) was minimal with also little nitrogen fixation.humid tropical region, where MAR decreases from to mm (Table1).

At each location, we evaluated two types of livestock system: extensive pastures systems and intensive silvopastoral systems. In addition, at each location, a natural forest site (tropical forest in all cases) was used as a reference for original soil fertility conditions.4 Tropical pastures within regional and global ecosystems 20 Hydrology 20 Regeneration of degraded land 22 Biodiversity 24 Atmosphere and global warming 27 5 Conclusions 31 6 References 33 7 List of keywords
