In the course of the subsequent 30 years, farmers needs to produce 70% extra rice than the 550 thousands lots produced this day to feed the expanding inhabitants. Nitrogen (N) is the nutrient that almost all usually limits rice creation. At present degrees ofN use potency, we are going to require no less than double the ten million lots of N fertilizer which are at the moment used every year for rice creation.

Constitutes the basis of pulsed amperometry. The series of potentials applied for deﬁned time periods is referred to as a waveform. The potential E1 applied over the time period, t1 , is subdivided into two time periods related to two functions. In the initial part, called the delay period (td ), time is allowed to permit the current to stabilize due to changing potentials so that only stable current from analyte oxidation is measured during the second part of E1 , the detection period (tdet ), also known as integration time (ti ), as data acquisition takes place to integrate peak areas during this time.
