During the growing season, i.e. intensive growth, lawns are fertilized 3 to 4 times. The fertilizer used after the first mowing of grass is ammonium nitrate, i.e. ammonium nitrate. Used as a one-component fertilizer or added to mineral mixtures. Its use allows for the extension of the growing season and increases the weight of the above-ground part of the plant. S altpeter increases the quality of amino acids and proteins. As a result, it improves the technological value of the crops.
Ammonium nitrate contains the highest amount of nitrogen, as much as 34% of all ammonium nitrate fertilizers. It is well soluble in water, so it can be used to prepare liquid solutions for watering the lawn. The composition of ammonium nitrate is two forms of nitrogen: nitrate and ammonium. It has the form of white granules. It quickly penetrates the soil and strengthens the plants.Ammonium nitrate - when to use?The first lawn fertilization in the new year is performed in spring at the turn of March and April. It is best to do this after mowing the grass. The elements such as nitrogen, phosphorus, potassium, calcium and magnesium should be supplied to the soil at this time. Ammonium nitrate for your lawn will result in lush growth of turf. The ammonium form of nitrogen used in spring accelerates the vegetative development of plants and increases the leaf blade.Fertilization should be done before rain. It is not recommended to spread the fertilizer on wet grass after rain. It is also forbidden to do this in times of drought.The use of iron during summer fertilization will give the grass a distinct color and inhibit the development of mosses on the lawn.
Ammonium Nitrate DosageThe first ingredient that grass needs to grow is nitrogen. The fertilizer is ammonium nitrate, dosed in the amount of 1.5 kg / 100 m2. It allows the grass to grow quickly, compact and improve its color. The fertilizer may be spread over the lawn. After this treatment, the grass must be watered. Another way is to dissolve ammonium nitrate and water the lawn. In May, a complete mineral fertilizer or a solution of ammonium nitrate with magnesium and calcium is used. They are dosed: 5-10 liters / 100 m2. In the fall, grass s altpeter is used as a multi-component fertilizer with an increased content of potassium and phosphorus. Such a mixture will allow the turf to become frost-resistant and facilitate the survival of the winter in good condition.The applied doses of ammonium nitrate are determined on the basis of the substance content in the soil as well as the needs of the cultivated plant species.Excess nitrogen is deposited in plant tissues or is washed away by groundwater. This has an impact on environmental pollution and eutrophication, i.e. water blooming. Even in the case of vegetable crops, exceeding the dose of ammonium nitrate is detrimental to human he alth. Therefore, the fertilizer dose should be determined in accordance with the manufacturer's recommendation - both in the vegetable garden and on the lawn.How long does ammonium nitrate work?It is a universal fertilizer that is commonly applied to all plants, including cultivated ones, and to various types of soil. Ammonium nitrate is quickly absorbed and penetrates into the soil, strengthening the plants. It also has the property that nitrogen remains in the substrate for a long time. This is because ammonium nitrate is composed of two types of nitrogen. Nitrate form - NO3 - fast-acting, immediately available to plants. On the other hand, the ammonium form -NH4 penetrates more slowly and is therefore available for longer. In the case of a lawn, it is fertilized up to four times a year to maintain the proper nitrogen concentration in the soil.A simple way to get rid of the roots of a felled tree is to use ammonium nitrate fertilizer on it. Nitrogen fertilizer is applied to tree trunks in loose or liquid form. The roots must first be dug, the soil and part of the wood removed so that you can get inside. Nitrogen is needed by the microorganisms that break down wood. Once delivered, such a breakdown will be much faster. The treatment should be repeated several times, using small concentrations of fertilizer. After two or three years, the trunk and roots will disappear. They will turn into humus, which will additionally fertilize the soil.Ammonium or calcium nitrate?Calcium nitrate contains easily assimilable nitrogen in the form of nitrate as well as calcium, which gives a greater yielding effect compared to ammonium nitrate. In addition, it allows for increased harvest stability. The purchase of calcium nitrate, however, generates higher costs. The price of ammonium nitrate is much lower.Over the years, quality will exceed costs as yields will be higher. In the case of lawns, the use of calcium nitrate will result in faster recovery of the green color. Calcium nitrate has a better impact on the environment, does not cause soil acidification, and even stabilizes its pH by itself.Ammonium nitrate - priceS altpeter - a fertilizer produced in Poland by Grupa Azoty Zakłady Azotowe Kędzierzyn, Grupa Azoty Zakłady Azotowe Puławy and Grupa Azoty Tarnów. As a country, we have a very high share in the world production of this fertilizer. During the year, the nitrogen plants produce 1.1 million tonnes of ammonium nitrate. It is the cheapest one-component mineral fertilizer. Its price exceeds PLN 1,000 per ton.For private crops, you can buy this fertilizer in smaller packages. For example - 3 kg of ammonium nitrate cost about PLN 15.
