Mixing ratio of sodium nitrophenolates and urea as base fertilizer and topdressing fertilizer

① Base fertilizer mixing ratio

Sodium Nitrophenolates and urea are mixed as base fertilizer, that is, before sowing or planting. The mixing ratio is: 1.8% sodium nitrophenolate (20-30 grams), 45 kilograms of urea. For this mixture, one acre is generally enough. In addition, the amount of urea can be adjusted appropriately, mainly according to the soil conditions.

② Topdressing mixing ratio

Regarding the mixing ratio of topdressing, there are also two different methods: soil topdressing and foliar topdressing.

First, the soil topdressing method, the mixing ratio is 1.8% Sodium Nitrophenolates (5-10 ml/g) and 35 kilograms of urea. This ratio formula is also about 1 acre. Soil topdressing uses this mixing ratio, and it is recommended to use the buried application method, which will have a better effect.

Second, the foliar fertilizer topdressing method, the mixing ratio is: 1.8% Sodium Nitrophenolates (3 ml/g), 50 grams of urea, and 60 kilograms of water.

However, spraying is sensitive to the growth period of crops, and it must be used in the best growth period for better results. For example: in the seedling stage, flowering and fruiting stage, and swelling stage, spraying once in each growth period will have a better effect on promoting growth.

Summary: The effect of mixing Sodium Nitrophenolates and urea is definitely 1+1 greater than 2. Urea is a nitrogen fertilizer with a relatively high nitrogen content, and Sodium Nitrophenolates is a very good solution for plant growth regulation. The mixed use of urea and Sodium Nitrophenolates can quickly increase the photosynthetic rate of leaves, greatly improve the utilization rate of nitrogen fertilizer, and significantly increase production. It is called the "golden partner" or "golden formula" of fertilizer and pesticide compounding.
