More ways to increase nitrogen fertilizer utilization

Nitrogen is a large amount of essential elements for crop growth and plays an important role in promoting crop growth and increasing yield. Therefore, nitrogen fertilizer is widely used in production. However, many farmers are currently over-reliant on nitrogen fertilizer, and some plots use nitrogen fertilizer more than crops throughout the year. 50%-200% of the required fertilizer, not only wastes fertilizer, but also pollutes the groundwater source, destroys the agglomerate structure of the soil, leading to a decline in arable nature, causing a large area of ​​disease, how to rationally use nitrogen fertilizer, improve its utilization rate, and reduce Production cost has become an important issue in fertilization. The effective methods to increase nitrogen use efficiency are summarized as follows:
First, a small number of times, deep application of soil. A small amount of multiple times can make more nitrogen nutrients absorbed by crops and reduce losses. Ditching, digging, and applying to the soil can greatly reduce the loss of nitrogen nutrients due to volatilization, and the floating surface is not only lost, but also In the plastic arch shed environment, crop damage will occur due to nitrogen accumulation.
Second, look at the weather conditions and fertilize. The application of urea to the soil undergoes an ammoniation process as the temperature increases. Therefore, urea should be applied when the temperature is high. When the temperature is low, ammonia and ammonium bicarbonate should be applied, and the nitrogen fertilizer should be sprayed on the foliar surface. The fertilizer efficiency is related to the length of time the fertilizer liquid stays on the leaf surface. If it is sprayed when the light is sufficient and the temperature is high, the water will evaporate quickly, and it is difficult for nitrogen to enter the leaf cells; if it rains after spraying, the nitrogen fertilizer will be lost, which will lose the effect of foliar spray, so it is most suitable. The time is cloudy without rain or after 4 pm.
Third, fertilize according to soil conditions. The clay soil is sticky and the nitrogen volatilization is less. The amount of nitrogen used at one time can be slightly larger. The water retention capacity of sand soil is poor, and the nitrogen application rate is best based on the principle of eating less and eating more.
4. Fertilize depending on the type of crop. Nitrogen long leaves and phosphorus long fruit, potassium fertilizer can grow longevity, leafy vegetables such as cabbage, green vegetables, leeks, leeks, etc., topdressing can be mainly nitrogen fertilizer, but fruit vegetables, such as melons, solanaceous fruits, in addition to seedling stage In addition to nitrogen, other elements such as phosphorus and potassium are needed in other periods. Excessive nitrogen fertilizer not only has low utilization rate, but also causes plants to grow in length. As a result, flowering is delayed and yield is reduced. In addition, rhizobium of legumes such as soybeans and peanuts can fix free nitrogen in the air, and can be applied less or not.
5. Fertilization during different growth stages. The germination period mainly uses the nutrients stored in the seeds, and rarely absorbs the soil nutrients. The root system is still underdeveloped at the seedling stage, and the soil nutrients are still not much. If excessive nitrogen fertilizer is applied, the excess nitrogen fertilizer will accumulate in the soil. Nutrient growth and long-term results require a lot of nutrients. It is necessary to fully supply fertilizer, but it is necessary to pay attention to the reasonable combination of various fertilizers. It is not possible to apply nitrogen fertilizer. The production adopts measures such as staged fertilization, blending and blending, fertilization and irrigation to exert the effect of fertilizer and improve its utilization rate.

Electroplated Diamond Abrasive Products

Superabrasives are tools used in precision grinding,precision cutting,precision polishing and precision drilling,like flexible diamond abrasive.Superabrasive materials attach to a wheel,blade and drill to make Superabrasive grinding wheels,cutting balde and drilling bit.The reason some abrasives are Superabrasives is due to their extraordinary hardness,unparalleled performance,and longevity.
What are Superabrasives?
Abrasives that belong to the Superabrasive family includes,Industrial diamonds: an industrial diamond is a non-gem quality small diamond that is for abrasives,cutting,and drilling tools.
Cubic boron nitride (CBN): Usually called CBN it is the second hardest cutting tool material after a diamond.
Polycrystalline: Is an abrasive material that has a multiple collection of crystal grain structures with individual orientations
CVD Diamond: These are synthetic diamonds made by a process known as chemical vapor deposition.CVD diamonds grow from a hydrocarbon gas mixture. They are extremely hard,have a high thermal conductivity that is five times that of copper. They also have broadband optical transparency,are chemically inert,and only reach graphitization at very high temperatures.
Nanodiamonds: These tiny diamonds are the product of a controlled explosion. Sometimes called a detonation nanodiamond (DND) or an ultradispersed diamond,as this is how they form.
Industries That Use Superabrasives
A great number of industries use Superabrasive grinding wheels and the coated abrasives subsection of the abrasives industry continues to grow. Industries that are prime buyers of Superabrasive grinding wheels are,

Aerospace
Jewelry
Aluminum Mills Leather Tanneries
Automotive Machinery
Bearings Marble
Boat Building Medical Instruments
Brick & Tile Metal Fabrication
Broaches Metallurgical Labs
Ceramic Products Motor Vehicle Parts
Construction Oil Field Equipment
Contract Machining Paper Mills
Copper Mills Plastics
Cutlery Precision Gages
Cutting Tools Railroad Equipment
Dental Equipment Rubber
Forest Products Saw Blades
Foundries Ship Building
Gears Springs
Glass Products Steel Mills
Golf Clubs Valves
Granite Welding

Advantages of Superabrasives
The advantages of Superabrasive grinding wheels are more than extraordinary hardness,unparalleled performance,and longevity. These three features of Superabrasives are the core of many advantages manufacturers gain by an aggregation of services that normal abrasives simply cannot deliver.
These include:
Less expensive tooling and fixturing costs
More wheels on the spindle,smaller wheels,multiple operations
Less floor space needed for manufacturing
Virtual elimination of wheel wear
Automated CNC machines,less labor intensive operations requiring less training
Consistent surface speed from part to part
Better overall throughput with fewer machines needed
Improved Material Removal Rates,Lower Per Part Abrasive Costs and higher speeds
With Superabrasives,production increased by automated CNC equipment,industries have found one way to compensate for the lack of availability of skilled labor. With fewer machines needed,so is fewer workers. With Superabrasives CNC,automation is more concerned with defining a manufacturing process using machine capabilities and mechanization. There is less concern on operator technique. A properly defined process,combined with automatic loaders make for equipment that is almost running itself.
Industry Outlook
Future growth of the abrasives industries will primarily be in Superabrasives. Currently,research and development of Superabrasives are taking place in the following areas.
Custom designed [hard to grind" materials in an increasing number of industries
Creep or deep feed grinding
High-speed,high-performance grinding of hardened steel
Form grinding,sometimes with electroplating,in high precision,high-removal,and high-surface quality applications
CNC-control of line grinding machines
Other abrasive technology developments with Superabrasives are likely to occur in using CVD for the best bonding of coatings to diamond wheels
