Scientists have developed a model to calculate the age of nitrogen in corn and soybean fields, which could lead to improved fertilizer application techniques to promote crop growth while reducing leaching. Nitrogen, a key nutrient for plants, can cause problems when it leaches into water supplies.
Overview:
Malnutrition
Rapid population growth and crippling economic problems in many African countries have reduced living standards and adversely affected eating habits, causing widespread malnutrition. In Nigeria, a faltering economy has led to declining imports of costly protein-rich food. Moreover, currency devaluations in other countries have resulted in drastically reduced imports of oil and animal feed.
