Suspending the Application of Mobile Nutrient-specific Fertilizers
This study was conducted to determine the effects of suspending the application of mobile nutrients-specific fertilizers on the concentration intake of nonmobile nutrients in rice. Mobile nutrients, considered as fast moving nutrients, enter the roots of plants at maximum amounts while the nonmobile or the slow-moving nutrients, enter the roots in minimum amounts later than the mobile nutrients.
The researchers suspended the application of mobile nutrients nitrogen and potassium to allow maximum absorption of nonmobile nutrients (zinc, copper, iron, and manganese).
Although food production is being promoted in developing countries, food security continues to be a significant issue. This is primarily because population expansion kept up with improvement of production. Among the commodities being improved is rice, which serves as staple food source of most Asian countries.
Every crop requires fertilizer and this most of the time, is supplied by synthetic fertilizers. In coordination with the chemical inputs used, fertilizers served significantly in the increase in food production, where yields are reinforced. Nevertheless, there are reports that rice production seems to slow down even if the use of fertilizers is increased.
Further clarification of the procedures and results should be directed to the researchers and adviser.
