What role does infrastructure play in sustainable agriculture?
Infrastructure development is a critical, long-term investment for connecting farmers both to input and output markets. The African Union has set a goal of increasing fertilizer use from an average 8 kilograms per hectare today to at least 50 kilograms by 2015.
How do fertilizer best management practices help?
More precise use of fertilizer can help increase its efficiency and cost-effectiveness. This means using the right source of nutrient, at the right rate, at the right time and in the right place.
Is there a sustainable supply of minerals to meet future fertilizer demand?
There is no indication that phosphate production, a primary mineral source used in fertilizers, will peak in the next 20-25 years or even within the next century.
How are innovations helping farmers?
More precise fertilizer application can be achieved by improving the accuracy and timing of applications through the use of engineering and computer-aided technologies, such as remote sensing.
What role did fertilizers play in the âGreen Revolutionâ?
In the 1960s, the breeding of improved varieties of rice, wheat and maize, combined with the expanded use of fertilizers, other chemical inputs and irrigation, led to dramatic increases in yields in Asia and Latin America. Since then high-yielding varieties have been developed for other major food crops. This is known as the âGreen Revolutionâ.
