Price, reviewed by Thomas H. Langlois, LITERATURE REVIEW THE NEED FOR NITROGEN FERTILIZATION OF GRASS PASTURES. INTRODUCTION With the increase in human population in South Africa, less natural pasture is available for animal production.
As a result, there is a growing interest in intensive grassland production in order to sustain the same, or even better, level. This book has been cited by the following publications. a review on management and methodological progress in the tropics.
animal, Vol This book sets out to examine the problems involved in the utilisation of tropical and subtropical pastures and to explain how pastures may be managed to meet the requirements of both plants and animals.

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).

The need for liming is minimal as most important tropical legumes (except glycine) and grasses are adapted to acid soils, the legumes having the ability to extract Ca.

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
