Characterization 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 کاملGrowing 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 کاملEffect of Slow Release NPK Fertilizer Sources on the Nutrient use Efficiency in Turmeric (Curcuma longa L.)
Nutrient losses due to leaching, volatilization and fixation and the activated risk of nitrate leaching after fertilizer addition to the soil may be reduced through the use of slow-release fertilizers. Turmeric, a long duration and high yielding commercial crop consumes greater amount of nutrients from the soil as well as from applied fertilizers for a prolonged period. A field experiment was c...
متن کاملFertilizer NPK from human urine and olive oil mill wastewaters
The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two s...
متن کاملSynthesis of merlinoite from Chinese coal fly ashes and its potential utilization as slow release K-fertilizer.
This study focuses on the synthesis of merlinoite from Chinese coal fly ashes by KOH direct conversion method, with special emphasis on the application of synthetic merlinoite as fertilizer. These fly ashes were collected from two pulverized-coal combustion (PCC) power plants in Xinjiang, Northwest China. The synthesis results are influenced by fly ash characteristics and different synthesis co...
