Book Description
Farmers apply fertilizers to crops in order to produce maximum economic return. To attain this, it is important that fertilizer requirements can be estimated accurately. The prevention of excessive use of fertilizers on economic grounds also has the beneficial consequence of minimizing environmental pollution of groundwaters through the leaching of unused fertilizers. This book is intended for both the agricultural scientist who is engaged in research on the use of fertilizers in crop production and consultants who might assist with the interpretation of statistical data. Relevant mathematical and statistical procedures are described critically, indicating their basis and limitations, and how they may be used or misused. Some basic knowledge of statistics is assumed on the part of the reader. Many of the procedures have been developed by the author from experience in soil fertility projects in Australia, Canada, the USA and a number of less-developed countries.

Book Description
This is a joint study involving five organisations from both the public and private sectors. The objective is to explore the future need for fertilizer required to support the Food and Agriculture Organization's (FAO) projections of agricultural commodity production for 2015 and 2030. The paper begins by briefly reviewing attempts to identify and quantify the factors influencing the growth in demand and supply for agricultural commodities. Several studies that estimate long-term fertlizer use are also reviewed, followed by a discussion of the forecasting methods and data. The results and implications conclude the paper. The study projects growth rates of between 0.7 and 1.3 per cent, depending on assumptions about nutrient efficiency over the next 35 years
