Fertilizer mixing requires care; only scientific combinations boost effectiveness
Many vegetable growers are in the habit of buying a large quantity of fertilizer at one time when prices are low and storing it for use throughout the year. Although this practice is workable, it is quite unsuitable for certain chemical fertilizers. Because vegetable growers have no dedicated place to store fertilizer, storing it casually will cause some fertilizers during storage to...
Mixing human feces and urine with superphosphate. To every 50 kg of human feces and urine, add 2.5 kg of superphosphate, stir evenly, and store for 5-7 days before use. This treatment can convert the highly volatile ammonium carbonate in human feces and urine into the stable compound ammonium phosphate, thereby preventing nitrogen loss and increasing the phosphorus element in human feces and urine, using phosphorus to preserve nitrogen and improving fertilizer quality.Adding gypsum powder to human feces and urine. To every 50 kg of human feces and urine, add 5 kg of calcined gypsum powder, then add 25 kg of water, mix thoroughly, cover and store for 10 days before use; this can reduce nitrogen volatilization loss.
Adding superphosphate to plant ash. To every 3 kg of plant ash, add 50 kg of water, soak for 6 hours, then take the clear liquid (filtrate) for later use; separately take 1 kg of superphosphate powder, add water, stir evenly, let it settle naturally, then take the filtrate; then mix the two solutions evenly, add 50 kg of water and spray, enough to spray one mu of field, and it can achieve the same fertilizer effect as potassium dihydrogen phosphate.
Adding superphosphate to barnyard manure. Add 20% superphosphate powder to barnyard manure, stir evenly, then pile it for more than 20 days; this not only prevents the volatilization and loss of nitrogen in the barnyard manure, but also speeds up the decomposition of the barnyard manure, increases the organic phosphorus content, and improves the effectiveness of the nutrient elements in the fertilizer.
Adding ammonium bicarbonate to composted manure. Cut crop stalks into short pieces, add 0.5%-1% ammonium bicarbonate and an appropriate amount of human feces for composting, then cover and seal with mud slurry; after decomposition it becomes a highly effective biological potassium fertilizer.
However, when mixing different types of fertilizer, be careful to avoid blindness; in particular, alkaline fertilizers must not be mixed with acidic fertilizers, and alkaline fertilizers must not be mixed with one another either.
