CHEMICAL EVALUATION OF PHOSPHORUS, ZINC & COPPER TO STUDY SOIL FERTILITY STATUS OF SELECTED AREAS

Abstract

organic matter, minerals, gases, liquids& organisms are mixed with soli its supports to life. crop growth and production is depand upon the proper nutrition . nutrition is very essensial. The soil tests can help to determine the status of plant available nutrients and develop recommendations fertilizer to reach optimum crop production.It is used to Atomic Absorption Spectrometer (AAS) analyze metals at very low concentrations, typically in the parts per million (ppm) or parts per billion (ppb) ranges. A colorimeter is a device used in colorimetry. A specific solution have the absorbance of particular wavelengths of light .All living organisms are need Phosphorus (P) . Normal growth and maturity of the plant needs Phosphours. . A role of photosynthesis, cell division energy storage cell enlargement and transfer, respiration cell division, and several other processes in plants essential of phosphours. A plant must have normal production cycle is copmlited by hwelp of phosphours. Copper is water soluble and the particle size of the fertilizer is small so efficiency is improved if the fertilizer. Zinc ammonia complexes are typically found in starter fertilizers. They work well in liquid blends made from ammonium phosphate. Specific ammoniated zinc solutions can also be mixed with UAN or aqua ammonia solutions.
