1. The farmyard fertilizer can not be mixed with alkali ash, lime nitrogen, lime, calcium magnesium phosphate fertilizer and other alkaline fertilizers. Because the main component of human and animal urine is nitrogen, if it is mixed with a strong alkaline fertilizer, it will neutralize and fail.
2. Superphosphate cannot be mixed with alkaline fertilizers such as grass ash and lime nitrogen, otherwise it will reduce the effectiveness of phosphorus. Phosphate rock powder, bone powder and other insoluble phosphate fertilizers can not be mixed with alkaline fertilizers such as grass ash and lime nitrogen. Otherwise, insoluble phosphate fertilizers will be harder to dissolve and crops will not be able to absorb and use them.
3. Alkaline fertilizer such as calcium magnesium phosphate fertilizer cannot be mixed with ammonium nitrogen fertilizer. Because alkaline fertilizers and ammonia nitrogen fertilizers such as ammonium bicarbonate, ammonium sulfate, ammonium nitrate, ammonium chloride, etc., will increase the volatility of ammonia, thereby reducing fertilizer efficiency.
4. Unripe farmyard fertilizers cannot be mixed with ammonium nitrate. Because unfamiliar farmyard manures must be decomposed and rotted before they can be used by crops. If mixed with ammonium nitrate, the unripe farmyard manure loses nitrogen during decomposition and rot, so it cannot be applied together, otherwise both nitrogen will be damaged and the fertilizer effect will be reduced.
5. Chemical fertilizers cannot be mixed with bacterial fertilizers. Because chemical fertilizers have strong corrosiveness, volatility and water absorption, if they are mixed with rhizobia and other bacterial fertilizers, they will kill or inhibit viable bacteria and make bacterial fertilizers ineffective.
Digital 60m short range laser rangefinder is a laser measurement device which is supposed to replace tape measure, ruler, and other traditional length meauring tool. Laser ruler as its name, it is a electronic ruler which user laser to measure distance.
