Recovery straps and tow straps are sometimes used interchangeably, but it's important to note that both cannot be used for the same purposes. The main difference between a towing strap and a recovery strap is the fabric and its ability to stretch. These straps are made of a nylon fabrication so they can stretch. A vehicle tow strap is usually made of polyester which stretches less than nylon. A tow strap does just that: tows a vehicle behind another. You'll generally find a tow strap with hooks on each end. Traditional tow straps and chains are similar in their towing applications.

China is the country with the largest amount of nitrogen fertilizer in the world. The nitrogen fertilizer utilization rate is only 30% to 35%, and the loss is as high as 30% to 50%. Among them, ammonia volatilization is an important way for the loss of nitrogenous fertilizer. Most of the NH3 that enters the atmosphere is adsorbed on rainwater by dry and wet surfaces, and returns quickly from the atmosphere to the surface that is relatively near to where the NH3 volatilizes. According to Jenkinson's estimation, most of the NH3 will remain in the atmosphere for about 6 days and then return to the surface, 10% to 20% will be oxidized to nitrogen oxides, and most of the nitrogen compounds will enter dry lands, forests, grasslands, rivers, lakes, etc. with dry and wet deposition. It causes soil acidification and eutrophication of the water body, and has a huge impact on the environment. Increasing nitrogen use efficiency, reducing ammonia volatilization losses, and giving full play to the benefits of nitrogenous fertilizer production are urgent problems in nitrogen fertilizer application.
Studies have shown that, under different soil moisture conditions, the soil nitrogen utilization rate is different, mainly due to the different ammonia volatilization rates under different conditions. For dryland soils, ammonia volatilization occurs directly through the soil surface; under flood conditions, ammonia volatilization occurs at the interface between the water layer and the atmosphere. The greater the ammonia concentration difference between the water layer and the atmosphere, the more ammonia volatilizes. The use of slow-release fertilizers can greatly reduce the amount of fertilizer applied. When we studied the effects of SRF on ammonia volatilization under flooded and non-flooded conditions and on nitrogen use efficiency of rice, we found that rice was not subjected to waterlogging treatment and rice was under continuous water stress conditions, including During transplanting and returning to the green period, even mild water stress affected the growth and development of rice and reduced the nitrogen utilization rate. The growth status and nitrogen utilization rate of flooded rice are still higher than those of no flooding. Therefore, we can find that high soil moisture content can promote soil nutrient absorption. Soil nutrients can be measured by the soil NPK indicator.
And we can measure soil moisture at any time through a soil moisture meter. TZS-II soil moisture measuring instrument can be brought directly to the field to measure the soil moisture at any time. It emits electromagnetic waves at a certain frequency, and then calculates the soil moisture according to the change of the dielectric constant of the soil. Due to his convenience, It is also called a portable soil moisture tester. In addition, if you need to measure multiple soil moisture parameters, or soil moisture at different depths in the same place, we suggest that you use a fixed-point monitoring system to measure the water. It can also measure six different depths of water parameters.
