How to grow watermelons using calcium nitrate fertilizer?
During the seedling raising period:
Put 3-5 seeds on each nutrient bowl during seedling raising. The use of calcium to promote cell elongation and division can effectively promote the growth of new roots in watermelon, especially the increase of fibrous roots. At the same time, calcium has the function of stabilizing cell membranes and cell walls, which can effectively prevent damping-off and blight in the seedling stage.
Used as Base fertilizer:
Add 10kg-20kg/acre of calcium nitrate fertilizer to the base fertilizer. It can effectively reduce the cracked vines in the watermelon vine extension period, thereby reducing the occurrence of vine blight; at the same time, it can reduce the number of cracked melons and hollow melons in the first batch of watermelons. Data from Norwegian Hydro’s research institute in Germany show that calcium can effectively reduce hollow, crystal, and cracked melons and increase the storage period of watermelons.
What crops is calcium nitrate fertilizer suitable for? What plant likes ca nitrate?
Calcium nitrate fertilizer is suitable for a variety of crops, especially sugar beets, potatoes, barley and hemp. Calcium nitrate is also suitable for fruits and vegetables, which can enhance the stress resistance of crops, promote early maturity, and improve the quality of fruits and vegetables. It can be used as basal application, top dressing, flush application and foliar spray, and is also suitable for nutrient solution in soilless cultivation. The use of calcium nitrate can prevent physiological diseases caused by calcium deficiency, such as navel rot of tomatoes and peppers, leaf scorch of lettuce and cabbage, and deformities of cucumbers, etc.
How long is the effectiveness of calcium ammonium nitrate fertilizer?
The fertilizer effectiveness period of calcium ammonium nitrate varies according to different uses. When used as a nitrogen fertilizer, its effectiveness period is about 30 to 45 days; when used as a calcium fertilizer, its effectiveness period is about 15 to 30 days. It should be noted that the length of the fertilizer effectiveness period is related to soil and weather conditions. For example, if the soil is sandy or there is heavy rainfall, the fertilizer effectiveness period will be shortened accordingly. In addition, calcium ammonium nitrate is generally effective for 1 to 2 years, but correct storage methods are crucial to maintaining the effectiveness of the fertilizer.
What are the two common ways to use calcium nitrate fertilizer?
Use as base fertilizer:
According to the nutrient content of the soil, the amount of fertilizer applied determines the effectiveness of the base fertilizer. For example: cucumbers, tomatoes, watermelons, peppers, eggplants, etc., one acre of land requires 40 to 50 kilograms. Leafy vegetables: such as Chinese cabbage, spinach, celery, etc. Generally, 30 to 35 kilograms per acre of land can be used. For fruit trees, apply 40 to 60 pounds per acre of land.
Use calcium nitrate as a top dressing:
In addition to the use of base fertilizer, top dressing can also be used. However, there are two ways to top-dressing fertilizer. One is traditional trenching or drilling deep holes. The second is foliar top dressing. The traditional top-dressing method for fruit trees, solanaceous fruits, and melons is to apply 20 to 30 pounds of top dressing on the soil during the early flowering period, and 30 pounds per acre for leaves and rhizomes. You can also choose to spray top dressing on the leaves, mainly It is also a matter of concentration. Generally, the concentration of fruit trees is 500 times, while the concentration of vegetables is 600-700 times. Fertilizer spraying can be used from the seedling stage onwards, with an interval of 15 to 20 days and continuous spraying of 2 to 3 times.
What is the difference between calcium ammonium nitrate and calcium nitrate?
Calcium ammonium nitrate fertilizer and calcium nitrate fertilizer can quickly replenish nitrogen and calcium, and are suitable for acidic soils. However, remember that calcium nitrate cannot be used in paddy fields, because calcium nitrate is nitrate nitrogen and is easily lost with water. It cannot be mixed with fresh manure or compost, as it will cause calcium nitrate to decompose into nitric acid, resulting in loss of fertilizer nutrients.
What is calcium ammonium nitrate fertilizer?
Calcium ammonium nitrate fertilizer is an improved product of ammonium nitrate. Because ammonium nitrate is flammable and explosive and unsafe to transport, its use was banned in our country, so it was improved abroad. As a fertilizer, its nitrogen content is not as good as ammonium nitrate, but it is not easy to agglomerate. , good dispersion.
Which one is better, calcium nitrate or calcium ammonium nitrate?
Calcium ammonium nitrate fertilizer contains a large amount of calcium carbonate and has good effects when used as top dressing on acidic soil. When applied in paddy fields, its fertilizer efficiency is slightly lower than that of ammonium sulfate with the same amount of nitrogen, while when applied in dry land, its fertilizer efficiency is similar to ammonium sulfate. The cost of nitrogen in calcium ammonium nitrate is higher than that in ordinary ammonium nitrate. As a low-concentration fertilizer, calcium ammonium nitrate is a physiologically neutral fertilizer. Long-term application has a good effect on soil properties. It can be used as top dressing on cereal crops.
Is calcium nitrate fertilizer good for grass?
The effect of calcium nitrate on grass is to provide sufficient nitrogen content. Generally, 200-300lbs of calcium nitrate combined with appropriate temperature and moisture can make grass grow very well. Nitrogen fertilizer plays a very important role in the life activity, color and quality of lawns. In general, most lawn plants, with the exception of legumes, must meet their nitrogen fertilizer requirements.
How do I use calcium nitrate fertilizer on my lawn?
Calcium nitrate fertilization methods for lawns include spraying and spreading. Spraying is to dilute fertilizer with water into a solution and spray it on the lawn surface through sprinkler irrigation or other equipment, while spreading fertilizer is to spread all fertilizers directly on the surface of the lawn. When spreading fertilizer, in order to maintain the uniformity of the lawn, the fertilizer needs to be spread evenly on the lawn surface.
Does calcium nitrate raise soil pH?
Calcium nitrate is a commonly used soil conditioner and has a good effect in regulating soil pH. Calcium nitrate can be decomposed by soil microorganisms to produce nitric acid and calcium ions. Nitric acid can combine with cations such as calcium, magnesium, and ammonium in the soil to form salts, thereby reducing the acidity of the soil. At the same time, it can also provide the calcium needed by plants to promote plant growth and health. Therefore, calcium nitrate is widely used to improve and regulate soil fertility.
Is calcium nitrate a straight fertilizer? Does calcium nitrate dissolved in water?
Calcium nitrate fertilization generally does not require watering. Calcium nitrate [Ca(NO3)2·4H2O] is usually obtained by neutralizing limestone and nitric acid. It can also be a by-product of nitric phosphate fertilizer production. It contains 13% to 15% nitrogen. The appearance of calcium nitrate is white or slightly tinged. Small crystals of other colors are highly hygroscopic, easy to agglomerate, and easily soluble in water. The aqueous solution shows an acidic reaction, and the solubility is minimally affected by temperature. It is a physiological alkaline fertilizer.
