Nitrogen fertilizer synergist use science
   The addition of nitrification inhibitors to common nitrogen fertilizers and nitrogen-containing compound fertilizers is called stable fertilizer, and nitrification inhibitors are commonly called “ nitrogen fertilizer synergists †. There are three common types of nitrification inhibitors :
Nitrogen - pyridine The suitable amount is about 1% of pure nitrogen . When it is in the soil at a concentration of 1-100 mg / liter, it has a significant inhibitory effect on soil nitrification, and the effective period is 30 days. Nitrogen - pyridine has an effect of increasing yield or fertilizer for rice, corn, wheat, cotton, rape and other crops, but has an inhibitory effect on the growth and development of legumes.

Dicyandiamide Under the influence of dicyandiamide, the ammonium in the fertilizer can be stabilized for 6-8 weeks. Fertilizers incorporating dicyandiamide can be applied to most crops, including ammonium sulfate , ammonium nitrate, urea and ammonium nitrate. The amount of dicyandiamide is preferably from 5% to 10% of the total nitrogen . 1 month significantly inhibited after administration of Microbial, returned to normal after two and a half. Dicyandiamide is both a synergist and a slow-acting nitrogen fertilizer.
Dimethylpyrazole phosphate The application test on crops such as potato and summer corn has initially achieved the effect of increasing nitrogen production.
At present, there are many kinds of products containing nitrogen fertilizer synergists in the agricultural capital market. When selecting, we should refer to the field test effect and the quality of the products. And pay attention to whether it is safe for humans and animals, not harmful to seedlings, and has little side effects on beneficial microorganisms such as soil rhizobium. The production enterprise should clearly indicate the type of nitrification inhibitor, the amount of addition, and the range of nitrogen fertilizer use on the product packaging bag. Different types of nitrogen fertilizer synergists are suitable for different additions, some are 0.25% and some are 0.7%-1%. The effect of nitrogen fertilizer synergists varies greatly depending on the application conditions . For example, in irrigated land Most of the crops showed increased yield and the fertilizer efficiency of vegetable crops was uncertain . Most of the legume crops showed reduced yield . The soil conditions were better than that of dry land.
Gear Pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications.
Gear pumps are also widely used in chemical installations to pump high viscosity fluids. There are two main variations; external gear pumps which use two external spur gears, and internal gear pumps which use an external and an internal spur gears (internal spur gear teeth face inwards, see below). Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution. Some gear pumps are designed to function as either a motor or a pump.
Features:
l Only two moving parts
l Only one stuffing box
l Non-pulsating discharge
l Excellent for high-viscosity liquids
l Constant and even discharge regardless of pressure conditions
l Operates well in either direction
l Can be made to operate with one direction of flow with either rotation
l Low NPSH required
l Single adjustable end clearance
l Easy to maintain
l Flexible design offers application customization
