Climate-smart Crop-livestock Systems for Smallholders in the Tropics: Integration of New Forage Hybrids to Intensify Agriculture and to Mitigate Climate Change through Regulation of Nitrification in Soil

The purpose of this project: Small-scale farmers and research and development institutions apply the innovative approach of Biological Nitrification Inhibition (BNI) by Brachiaria humidicola forage grass hybrids to realize benefits in economic and environmental sustainability from integrated crop-livestock production systems

Quantifying the BNI-residual effect from B. Humidicola on subsequent annual crops

Our ongoing and past findings indicate substantial reduction in the soil nitrification potential from cultivation of B. humdicola due to accumulation of BNIs in soil systems. Other research groups working on Hyperrhenia diplandra pasture grasses in West Africa noticed a very stable BNI effect (but not properly quantified yet) on nitrification potential in soils. Thus, the aim of this proposed field study is to characterize the residual-BNI function from B. humidicola (BH) for the stability and intensity of BNI effect on soil nitrification potential, nitrogen-recovery and N-use efficiency in maize and soybean using the BNI-residual effect from a long-term cultivation (> 10 year pasture) of BH pasture.

This field study aims to characterize the residual effect of biological nitrogen inhibition (BNI) from Brachiaria humidicola to determine the stability and intensity of the BNI effect on soil nitrification potential, nitrogen (N) recovery, and N-use efficiency in maize, based on the observed BNI-residual effect from a long-term cultivation (>= 10-year) of B. humidicola pasture.

Eco-efficient crop and livestock production for poor farmers in the sub-humid hillside areas of Nicaragua

This project aims to improve livelihoods of rural poor in sub-humid hillsides of Nicaragua by enhancing eco-efficiency in rural landscapes through the application of the Quesungual Slash and Mulch Agroforestry System (QSMAS) in combination with enhanced forage-based technologies as the basis of an integrated land use management strategy.

Development of Brachiaria genotypes adapted to poor soil drainage to increase cattle production and adapt grazing systems to climate change in Latin America

CIAT Corporate Communications — Fri, 20 May 2011 20:20:30 +0000

This project aims to develop genotypes of Brachiaria with higher tolerance to waterlogging and more productivity than the commercial cultivars for livestock systems in humid zones, which are suffering the uncharacteristic periods of waterlogging due to extreme weather events associated with climate change in Latin America and the Caribbean. We also aim to identify waterlogging tolerant Brachiaria genotypes using the farmer participatory research approach.
