Fertilizer subsidies may constitute a key economic tool with which to provide food for the growing population. Therefore, this work aimed (i) assess effectiveness of subsidized chemical (NPK) fertilizer use in production by comparing crop output between developed and developing regions (ii) examine benefits organic need its such as Africa. Secondary data from 2000 2019 on global use, production...

Nitrate can carry over in many medium and fine textured Wisconsin soils especially when growing season rainfall is below normal and yields are lowered by moisture stress. Most areas of Wisconsin received below normal precipitation during the 2003 growing season, and nitrate carryover could be an important factor affecting nitrogen needs in 2004. Taking carryover nitrate into consideration may b...

Fertilizer efficiency directly affects the production of continuous cropping greenhouse cucumber. So analyzing the fertilizer efficiency is of great significance in providing decision-making support for fertilization of greenhouse cucumber. By establishing the DEA models of continuous cropping greenhouse cucumber and taking existing data samples as study objects, the problems of fertilizer effi...

Ask prices are the most essential form of information feedback in Iterative Combinatorial Auctions (ICA) and vital in achieving an efficient auction outcome. Different pricing concepts have been analyzed in the literature, including linear, non-linear and discriminative non-linear prices. Linear prices, i.e. per-item prices, are intuitive and easy to understand for bidders, however, under certa...

Crude Palm Oil (CPO) is the mainstay of Indonesian agricultural products which largest CPO producing country in world. The high market share exports reflects competitiveness global market. purpose this study to determine CPO, concentration industry, and analyze factors that are suspected affect industry Indonesia. data used secondary with a five-digit ISIC (10432) using time series for 2001-202...

Low-stabilization scenarios consistent with the 2 °C target project large-scale deployment of purpose-grown lignocellulosic biomass. In case a GHG price regime integrates emissions from energy conversion and from land-use/land-use change, the strong demand for bioenergy and the pricing of terrestrial emissions are likely to coincide. We explore the global potential of purposegrown lignocellulos...

excessive use of fertilizer, herbicides and pesticides. Zoning systems can be used to protect the best agricultural soil from urban sprawl. Subsidies could be used to encourage people to purchase tools and other inputs that have a less harmful impact on soils, while certifi cation of sustainable crop and livestock practices can make produce more commercially attractive at higher prices.” Addres...
