How to use trace element fertilizer?
Microelement fertilizers are mainly inorganic salts or oxides. Some minerals and metallurgical by-products or waste materials can often be used as raw materials for microelement fertilizers. The production method is the same as that of inorganic chemical products.
Due to the small amount of application per unit area, it must be diluted with a large amount of inert substances before application. Uneven application will poison some crops. Microelement fertilizers often need to be mixed into macro fertilizers and applied together, usually in two ways: one is to mix them in the production of macro granular fertilizers. This method is more convenient and economical, and does not produce uneven nutrients. The disadvantage is that it is less flexible and difficult to meet the various requirements of the market; the other is to coat the surface of the macro-granular fertilizer with the trace element fertilizer powder. This kind of operation can be carried out in the secondary processing plant, which can meet the needs of the market at any time.
There are two ways to apply trace element fertilizers: soil application and foliar spraying.
Soil fertilization: In addition to chemical fertilizers (such as borax, zinc sulfate, manganese sulfate, etc.), the commonly used micro-fertilizers also include glass fertilizer, slag or scraps, which are usually used as base fertilizer or seed fertilizer. The application method is as follows: before sowing, combine with soil preparation and apply it into the soil, or mix it with nitrogen, phosphorus, potassium and other chemical fertilizers, and apply it uniformly. The application amount should be determined according to the types of crops and micro-fertilizers, and generally should not be too large.
Extra-root topdressing: mix soluble micro-fertilizer into a certain concentration of aqueous solution, and spray the crop stems and leaves. The advantage of this method is to avoid the harm caused by uneven fertilizer in the soil, and it can also be sprayed multiple times according to specific needs at different development stages of the crop to improve fertilizer efficiency.

We may usually see monitor devices in private cars, and they are called the car cameras. Today I'd like to introduce you another type of car cameras, the car cameras for vehicles with special purpose such as police cars, school buses, tanker trucks, container truck, Taxies, buses... Generally Speaking, the monitor devices used for these vehicles need to be much more stable so multiple car camers should be combined together to reach that monitor effect, then a monitor system formed, and we call this kind of monitor system the Vehicle Surveillance System(Car Security Camera System).

The Vehicle Surveillance System(Vehicle Security Camera Vehicle Camera Systems)(a three-layer networked comprehensive monitoring system), composed of a vehicle terminal, a transmission network, and a monitoring center, mainly provides the functions such as the vehicle anti-theft, anti-robbery, driving route monitoring, real-time wireless transmission of video images inside and outside the vehicle, rapid response to accidents, call command and so on, so that the problem of dynamic management of existing vehicles can be solved.
So what advantages of the vehicles with Vehicle Surveillance System(Car Surveillance Camera)?
1. Bank Money Transport Trucks, Tanker Trucks, and other Valuables Transport Vehicles: anti-theft and anti-robbery
2. Passenger Vehicles such as Buses, Long-distance Buses... : ticket anti-theft, passenger anti-theft and anti-robbery
3. Ambulances: patient treatment process monitoring and video recording, which can be as the evidence once the medical malpractice dispute happened
4. Police Cars, Fire Trucks: case handling process video recording, which can be as the material and evidence of the investigation after
5. Environmental Monitoring Vehicles: record the environmental pollution scene (which can be as the prosecution evidence) and transmit real-time informations to the Environmental Monitoring Center meanwhile(which can help the Environmental Monitoring Center take effective measures on the pollution source right away)
6. Trains, Steamships... : security monitoring, real-time recording
7. ...
