Previous Section Next Section A brief review of slow-release fertilizer technology Slow-release nitrogen fertilizers can be separated into three broad categories. This review article will not examine the use of natural organic N sources, and will focus instead on those slow-release products that are slow release due to a synthetic manufacturing process.
Sitko, and Nicole M.

However, substantially improving the performance of ISPs will require coordinated public and private investments in areas such as site-specific adaptive research and extension, which are necessary to turn potential CSA practices into profitable and adoptable farm management strategies.
Based on this analysis we propose the following as potential focal areas for improving the climate smartness of ISPs in Africa: Support greater concentration of ISPs on climate smart seed varieties, including drought and heat tolerant varieties and legumes.
Many ISPs currently focus primarily on staple cereal crops and fertilizers, with little attention paid to the characteristics of either. For ISPs to have a more system-wide effect on cropping systems and management practices, seed system constraints for other crops must be addressed.
ISPs can serve a catalytic role in this respect. Develop detailed farm registries for ISP beneficiaries: Detailed registries, that include geo-spatial information, are necessary to delivery support services such as weather-indexed insurance to farmers and to track adherence to targeting criteria.
There is currently limited consensus on what practices are most effective for heterogeneous smallholder systems; Extension advice and monitoring capacity remains very thin in most of Africa; and Governments may resist changing ISPs in ways that as yet have unproven benefits or may not be popular with farmers.
System support to improve timing of input distribution through ISPs: ISPs chronically deliver fertilizer late Xu et al. Late delivery reduces yields and crop response to fertilizer.
This unfavorably affects the ratio of crop output to GHG emissions. Improve beneficiary targeting of ISPs: ISPs must more effectively target farmers who can use fertilizer profitably but are not already using it or using it well below levels considered to be profit maximizing.
This will reduce crowding out of commercial demand and contribute to increased fertilizer use. In addition, effective targeting of farmers and regions affected by weather-induced disaster can help ISPs to support ex post household and system-wide recovery efforts.BIO-FERTILIZERS AND BIO-PESTICIDES RESEARCH AND DEVELOPMENT AT UPLB Pio A.

RESEARCH PAPER OPEN ACCESS Effects of water deficit stress and nitrogen fertilizer on wheat. Introduction about Fertilizer and Organic Fertilizer Definition of Fertilizer: Fertilizer (or fertilizer) is any organic or inorganic material of natural or synthetic origin (other than liming materials) that is added to a soil to supply one or more plant nutrients essential to the growth of plants.

URBANA - The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began.
