Growing Potatoes with Slow-release Nitrogen Fertilizer
Nitrogen management practices have an effect on crop yields but they can also have a negative impact on the environment. Practices such as banding fertilizer and/or split-applying total nitrogen needs per acre offer a more efficient use of nitrogen by significantly reducing nitrate leaching potential. Heavy rains occurring when plants are small and nitrogen demands are low can also increase nit...
متن کاملCharacterization and Utilization of Zeolite for NPK Slow Release Fertilizer (RESEARCH NOTE)
Based on various characteristics of zeolite, its utilization in the manufacture of fertilizers with slow-release properties is possible. The objectives of this study are to characterize and utilized nitrogen, phosphorus and potassium (NPK) slow release fertilizer by using natural zeolite in Indonesia. In this research, zeolite was utilized as a mixture of Slow Release Fertilizer (SRF). Effect o...
متن کاملNitrogen Response Index as a Guide to Fertilizer Management
The efficiency with which fertilizer-nitrogen (N) is transferred to grain-N in cereals is usually less than 50% and averages 33% worldwide. Two long-term N fertility experiments were evaluated to examine temporal changes in nitrogen use efficiency (NUE) and their causes. Averaged over 30-yr, non-irrigated winter wheat NUE was 49% at a 22.4 kg N ha 1 yr 1 rate and decreased to 34% at a rate of 1...
متن کاملEnvironmental impact of fertilizer use and slow release of mineral nutrients as a response to this challenge
This paper presents the most important issues relating to the infl uence of mineral fertilizers on both the natural environment and human and animal health. The physiological, environmental and economic impact of fertilizer production and application, resulted from a low assimilation of mineral components by crops, has been described. The research on the development and production of a large an...
متن کاملRecycling of manure nutrients: use of algal biomass from dairy manure treatment as a slow release fertilizer.
An alternative to land spreading of manure is to grow crops of algae on the N and P present in the manure and convert manure N and P into algal biomass. The objective of this study was to evaluate the fertilizer value of dried algal biomass that had been grown using anaerobically digested dairy manure. Results from a flask study using two soils amended with algal biomass showed that 3% of total...
