1. Do the base fertilizer. Potassium sulphate compound fertilizer has a wide range of nutrients and a wide range of applications. In the application, it is not necessary to apply other chemical fertilizers under normal circumstances. Due to the difference in concentration, the application amount is also different (the concentration of fertilizer commonly found on the market is 25%, 30%, 45%, etc.). For example, when the compound fertilizer with a concentration of 45% is applied as a base fertilizer, 40- per mu is applied. 75 kg, with a certain amount of decomposed organic fertilizer.
2. Do topdressing. At present, the ratio of general-purpose potassium sulphate compound fertilizer commonly used in agricultural resources market is nitrogen, phosphorus and potassium (15-15-15). For vegetables with more nitrogen fertilizer, nitrogen (such as urea) should be applied. It is also possible to use vegetable-specific fertilizers, and the principle of a small number of multiple fertilization should be mastered.
3. Foliar application. From the perspective of production practice, vegetable farmers are less used. When vegetables are severely deficient, they can be sprayed with potassium sulfate compound fertilizer, such as 45% compound fertilizer. The concentration is between 0.1% and 0.3%. It will be fine.
It is very important to control microbial activity in cutting fluid containers. Both bacteria and fungi can cause problems because they metabolize the components of the cutting fluid, resulting in the production of biofilm/mucus (large quantities of biofilm/mucus can exacerbate foaming problems and sticky surfaces) and secondary metabolites in the form of short-chain organic acids. The latter can result in a lower pH of the cutting fluid and an increased risk of corrosion. It is also important to note that high levels of bacteria and fungi can cause health problems for those operating the machines.
If the pH drops to less than 8.5, it may indicate bacterial growth in the cutting fluid. In such cases, we recommend measuring bacterial growth and replacing the cutting fluid if the test is positive.
Other signs of bacterial growth are a bad smell and fungal/bacterial film on top of the cutting fluid.
