In the Neotropics the predominant pathway to intensify productivity is generally thought to be to convert grasslands to sown pastures, mostly in monoculture. This article examines how above-ground net primary productivity (ANPP) in semi-natural grasslands and sown pastures in Central America respond to rainfall by: (i) assessing the relationships between ANPP and accumulated rainfall and indice...

In recent years, prices for N fertilizer have increased dramatically, reducing net returns of fertilized pasture systems. A 5-yr study from 2005 to 2009 was conducted to evaluate management strategies and relative differences in profitability for 3 methods of backgrounding calves on smooth bromegrass pastures. Forty-five steers were used each year for a total of 225 animals in a randomized comp...

ABSTRACT Agrosilvopastoral systems have been used as sustainable production models that can promote soil organic carbon (SOC) storage. However, there are no simulation studies with the Century model to estimate SOC accumulation capacity in long term, analyzing effects of management and climate change integrated crop-livestock-forest (ICLF) systems. This study aimed simulate C dynamics two chron...

Pastures are an underutilized and under-managed resource on many beef operations. Is it worthwhile to place more management emphasis on pastures? One might think that given the long winters we face in northwest Minnesota, we have to rely so heavily on conserved forages anyway that better management of pastures during the relatively short window they are useable may not be worth the effort. Howe...

forest roads are directions in natural habitats that used to transport wood products, secondary forest products and recreation. constructing forest roads causes trees clearing with specified width thus lead to direct or indirect changes in forest ecosystems and forest environment. this study aims to assess the changes of diversity and richness indices in main and secondary forest roads in a par...

The copper level in the serum of 1280 and liver of 200 goats raised in the mountain areas of Khuzestanprovince, Iran were determined. Copper, molybdenum and iron content of soil and pastures as well as sulfurcontent of the pastures were seasonally estimated. Mean serum copper levels of goats in Behbahan,Ramhormoz, Eizeh and Masjed-Soleyman districts were 8.14 ± 0.21, 1.98 ± 0.12, 7.74 ± 0.11 an...

Attalea speciosa (babassu) is a native palm of the primary forest from Amazonian and Cerrado biomes, has multiple economic cultural uses. However, this can become dominant in open areas, with long-term persistence community. The objective study was to compare population structure morphology babassu three habitat types characterizing succession: forest, pasture, babaçual (babassu-dominated secon...
