Bulk Blending Fertilizer (BB Fertilizer/Mixture of Fertilizer) is a kind of compound granular fertilizer mixed by several single fertilizers or compound fertilizers according to certain proportion. It has characters of granule uniformity, less water, moderate granule intensity, no agglomeration, easy to use and low cost.
The formulation (N,P,K content) of BB Fertilizer can be flexibly changed according to the crop`s nutrition requirement, local soil fertility, crops growing levels and other conditions, therefore BB Fertilizer is more scientific and targeted especially for balance fertilization.

A few days ago, the 11 newest provincial metrological standards newly established by the Jiangsu Academy of Metrology Science passed the on-the-spot assessment of the national metrological standards and metrological verification personnel appraisal committees, marking a new step in the standardization of the institute's construction, and the hospital’s social common use. The measurement standard system is further improved.
It is understood that these 11 measurement standards have two prominent characteristics - large social needs, urgently needed for industrial development. Including road management speed monitor verification device, transformer ratio bridge verification device, high-voltage electrostatic voltmeter verification device, coaxial low-power standard device, function signal generator verification device, fixed carbon and sulfur analyzer verification device, and coal Sulfur analyzer verification device, total organic carbon analyzer verification device, fluorescence spectrophotometer verification device, Abbe refractometer verification device, and Karl Fischer Coulometric micro moisture analyzer verification device involving traffic safety, electromagnetic voltage, radio frequency , chemical analysis and other fields.
The expert assessment believes that the metering standard device being assessed meets the requirements for carrying out relevant verification projects, the technical information is fully detailed, the uncertainty component assessment is comprehensive and reasonable, the personnel operation is skilled, the field test progresses smoothly, and the test results meet the requirements of the regulations.
