Soil mineral N dynamics and maize grain yields following Centrosema macrocarpum and Stylosanthes guianensis: Effects of different rotations and varying levels of N fertiliser
Published 2002“…More N was removed in the S. guianensis forage (140 kg N ha-1) compared to C. macrocarpum (90 kg N ha-1) although more N accumulated in the regrowth after harvest of C. macrocarpum (about 100 kg N ha-1––almost twice that of S. guianensis). Subsequently, the N status of maize plants (estimated using chlorophyll readings) in the first 37 days after sowing was higher for C. macrocarpum. …”

Trade liberalization, food, nutrition and health
Published 2015“…Following an overview of the different measures taken to liberalize food trade, this chapter goes through the four basic steps that can be taken to conduct such an assessment: (1) an assessment of the types of impacts trade liberalization could have, on a selected sub-set of key nodes in the food supply chain; (2) an assessment of the subsequent impact on food safety, food availability, food prices and food marketing; (3) an assessment on the foodrelated health outcomes themselves, namely foodborne diseases, undernutrition, and obesity and DR-NCDs; (4) an assessment of the implications of trade agreements on the policy space required to address these health conditions. …”
