O ver the past few years Malawi made remarkable progress toward increasing its national maize production and achieving food security owing to its long-running policy of subsidizing fertilizer. The implementation of these subsidy programs is continuously being improved upon as the country learns from past experiences. Recent evaluations of the current Farm Input Subsidy Program by Dorward and Ch...

We consider the potential for using prices as leading indicators of changes in stocks and yields in the freshwater capture fishery in Lake Victoria. Fertilizer run-off from agricultural land is a major cause of nutrient loading, along with soil erosion, atmospheric deposition, and point pollution from industrial and domestic affluent. The interactions between fertilizer applications, water qual...

Traditionally, sulfur responses have been limited to coarse textured or other soils low in organic matter that have little potential for sulfur mineralization. In the past, the burning of fossil fuels has contributed a significant amount of sulfur through deposition in rain. Also, many phosphorus fertilizers contained sulfur as impurities, which lessened the need for the application of sulfur t...

We also learnt much about the conditions under which agriculture-led growth is most likely to succeed. There are five key conditions. First, agricultural growth needs to be technologically driven so that output prices can fall while farm incomes increase. It is not enough to simply use more farm inputs like fertilizer and irrigation water and investments in productivity-enhancing agricultural r...

Most Indonesians rely on liquefied petroleum gas as one of their primary sources energy. Liquefied is classified into subsidized and non-subsidized. Subsidized primarily used by low-income households, small businesses, poor fishermen farmers for cooking. However, no exit strategy has been established to overcome the increase in government spending kerosene introduced 2008. The problem that macr...

estimated at 4.0 to 4.5 t ha 1 (Illy, 1997; Wopereis et al., 1999), and in general two crops per year are grown. Development of improved fertilizer recommendations entirely based This compares to average yields in the Sahelian and on field experiments is time-consuming and costly. We employed a comSavannah regions of 3.0 to 5.5 t ha 1. The cropping bination of two simulation models and selected...

The purpose of this research is to design a subsidized fertilizer information system equipped with prediction safety stock method. This study uses the waterfall methodology stages Analysis, Design, Coding, and Testing, as well method for prediction. By testing using black-box modeling Unified Modelling Language (UML) Business Process Model Notation (BPMN). results are prototype data collection ...

We develop a price competition model for a new supply chain that competes in a market comprised of some rival supply chains. The new supply chain has one risk-neutral manufacturer and one risk-averse retailer in which the manufacturer is a leader and retailer is a follower. The manufacturer pays a fraction of the risk cost (caused by demand uncertainty) to the retailer. We apply this competitiv...

A simple dynamic farm model is developed and used to analyse the net worth of a family farm grazing enterprise producing wool on the Northern Tablelands of New South Wales, Australia, under alternative assumptions regarding family expenses and investments in fertilizer. The linkage between family costs and expenditure on fertilizer is explored over a 25-year period highlighting the feed-back e€...
