A global spectral library to characterize the world's soil
World Agroforestry Centre (ICRAF)
Abstract
Soil provides ecosystem services, supports human health and habitation, stores carbon and regulates emissions of greenhouse gases. Unprecedented pressures on soil from degradation and urbanization are threatening agro-ecological balances and food security. It is important that we learn more about soil to sustainably manage and preserve it for future generations. To this end, we developed and analyzed a global soil visible-near…

Bridging the gap between climate science and farmers in Colombia
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/97481
Abstract
Agriculture is highly sensitive to variations in both weather and climate. Farmers face uncertainty in the weather patterns over the short term, and climate over the longer term. The CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) has promoted a system of Local Technical Agro-Climatic Committees (LTACs)4 in two Colombian…

Characterization of Crystalline Structure and Thermostability of Debranched Chickpea Starch-Lauric Acid Complexes Prepared Under Different Complexation Conditions
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/97141
Abstract
Chickpea starch was debranched with pullulanase, then complexed with lauric acid (LA) using two starch concentrations (3 and 10% w/w), two starch/LA mole ratios (1:0.1 and 1:1 mol anhydroglucose unit/mol LA) and two complexation temperatures (60 and 95 oC).…

Soil quality – A critical review
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/90970
Abstract
Sampling and analysis or visual examination of soil to assess its status and use potential is widely practiced from plot to national scales. However, the choice of relevant soil attributes and interpretation of measurements are not straightforward, because of the complexity and site-specificity of soils, legacy effects of previous land use, and trade-offs between ecosystem services.…

Tropical forage legumes for environmental benefits: An overview
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/90671
Abstract
Ruminant livestock production in the tropics, particularly when based on pastures, is frequently blamed for being detrimental to the environment, allegedly contributing to: (1) degradation and destruction of ecosystems, including degradation and loss of soil, water and biodiversity; and (2) climate change (global warming). In this paper we argue that,…

Predictability of seasonal precipitation across major crop growing areas in Colombia
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/97569
Abstract
Agriculture is one of the sectors that has greatly benefitted from the establishment of climate services. In Colombia, interannual climate variability can disrupt agricultural production, lower farmers' incomes and increase market prices. Increasing demand thus exists for agro-climatic services in the country. Fulfilling such…

Abstract
Neoleucinodes elegantalis Guenee (Lepidoptera: Crambidae) represents the most damaging pest of the Solanaceae family. Current studies have demonstrated that the species has differentiated into four races according to variations in female genitalia, wing morphometrics and…

Development of a QTL-environment-based predictive model for node addition rate in common bean
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/80542
Abstract
To select a plant genotype that will thrive in targeted environments it is critical to understand the genotype by environment interaction (GEI). In this study, multi-environment QTL analysis was used to characterize node addition rate (NAR, node day− 1) on the main stem of the common bean (Phaseolus vulgaris L). This analysis…

Abstract
Brachiaria grasses are sown in tropical regions around the world, especially in the Neotropics, to improve livestock production. Waterlogging is a major constraint to the productivity and persistence of Brachiaria grasses during the rainy season. While some Brachiaria cultivars are moderately tolerant to…

Potential Role of Fungal Endophytes in Biological Nitrification Inhibition in Brachiaria Grass Species
International Center for Tropical Agriculture (CIAT)
https://hdl.handle.net/10568/82881
Abstract
Brachiaria species have the ability to suppress nitrification in soil by releasing an inhibitory compound called ‘brachialactone’ from its roots; a process termed biological nitrification inhibition (BNI). This study tested the hypothesis that endophytic association with Brachiaria grass improves BNI activity of root…
