Types of superphosphate
Garden plantings need a lot of micronutrients, including phosphorus, for growth, then they will give a good harvest. If it is not enough, the plants stop developing, the leaves change color and fall off. It is imperative to feed the soil with mineral fertilizers based on phosphorus oxide. Its concentration can be 20-50% in the composition. The fertilizer is perfectly soluble in water, suitable for root and foliar dressing.
Depending on the solubility, the following types of superphosphates can be distinguished:
- Monophosphate. White powder containing 25% phosphorus oxide. One of the most inexpensive options. Poorly soluble in water, low efficiency. Stored for a long time.
- Double superphosphate. Compared to the previous version, it contains about 45% of phosphorus in the composition, the difference is almost two times. In addition, it contains iron, calcium sulfate, aluminum, monomagnesium phosphate. The effectiveness is also not very high, but it dissolves and absorbs better.
- Granulated. It has a very good effect on the composition of the soil. Contains 50% phosphorus and 30% calcium sulfate.
- Ammoniated. Perfectly soluble in water, ideal for oilseeds. Contains 55% potassium sulfate and 12% sulfur.
At the summer cottage, you can use all these types. Granular has an optimal price-performance ratio.
How to use
It is very important to dilute the fertilizer in water in the right proportion so that the microelements are better absorbed. The agent dissolves much better in boiling water than in cold water. For 3 liters of water, you need to take 20 tablespoons of the product and stir well. Immediately, the substance will not dissolve to the end, you need to remove it in a warm place and do not forget to stir. A wooden spatula works best.
Fertilizer will infuse within 24 hours. Then it must be diluted with clean water in a proportion of 150 ml of the composition per 10 liters of liquid. For greater effect, it is better to add 20 ml of nitrogen mixture and 0.5 kg of sifted ash to each bucket.
All plantings can now be sprayed. Superphosphates are most effective on alkaline and neutral soil. If the soil is acidic, additional preparation is needed - mix fertilizer with phosphate rock, limestone, humus. Otherwise, plants will not be able to assimilate all the nutrients.
It is important to maintain the correct proportions when diluting the fertilizer so as not to harm the plants. For example, spraying seedlings will require about 40 g of fertilizer per 1 sq. m. When planting potatoes, 4 grams are laid in the holes. For greenhouse vegetables, the ratio is 80 g per 1 sq. m.
So, thanks to fertilizers, the roots of plants are strengthened, the yield increases. It is important to use superphosphates in moderation and in the right proportion.
