Do you know the meaning of urea fertilizer: characteristics, benefits and dosage for rice? – Agrotek.id – Since time immemorial, Indonesian people have made rice a staple food in everyday life. Rice is the part of the grain that has been separated from the husk.
To meet people’s rice needs, rice production must be optimized by farmers. Various efforts are made to ensure that rice plants grow well and the results are satisfactory, one of which is by providing fertilizer to rice plants. Fertilization is needed so that the nutritional sources needed by rice plants can be fulfilled perfectly.
Broadly speaking, fertilizer consists of two types, namely organic/manure fertilizer (made from living creature material) and inorganic/artificial fertilizer (based on chemicals and made in factories).
According to recommendations from the government, both types of fertilizer are equally needed for rice plants.
There are several types of inorganic fertilizers that farmers commonly use for rice plants, one of which is commonly used is Urea (Ammonium Carbonide) Fertilizer.
Understanding Urea Fertilizer
Understanding Urea Fertilizer is a type of inorganic fertilizer made from a mixture of ammonia gas (NH3) and charcoal acid gas (CO2). The chemical formula of this fertilizer is NH2 CONH2.
Urea fertilizer contains a large amount of Nitrogen (N), namely 46%. So, every 100 kilograms of Urea fertilizer contains 46 kilograms of nitrogen.
Rice plants need nitrogen nutrients for growth, which can be obtained from Urea Fertilizer.
Physically, Urea Fertilizer is in the form of crystal grains with various colors, including white and pink (subsidized). Hygroscopic in nature, Urea fertilizer dissolves easily in water and is easily absorbed by plants.
This can make it easier for farmers to use Urea Fertilizer at the same time as watering the plants.
However, Urea fertilizer should be stored in a dry place and tightly closed so that it does not come into contact with water. Another characteristic is that the reaction of Urea Fertilizer is slightly acidic and is also easily burned by sunlight.
Characteristics of Urea fertilizer
- Has a very high nitrogen nutrient content.
- The shape is like crystals with a white color.
- The chemical formula is NH2 CONH2.
- It has the property of easily absorbing water and is very soluble in water. This means that the elements will be much easier for plants to absorb.
Signs of Urea Deficiency in Plants
Before you fertilize, it would be good to pay attention to physical signs that the plant is lacking Nitrogen. The following are the signs:
- Part or all of the plant slowly changes to a pale yellowish color.
- The process of plant growth becomes slow and if left alone it will be stunted.
- The color of old leaves changes to yellowish. Meanwhile, in rice plants the yellowish color starts from the tip of the leaf and continues to spread to the leaf veins.
- If it continues to be left, this lack of Nitrogen will have an impact on fruit that is not perfect and ripens before the time comes.
Benefits of Urea Fertilizer for Rice
By using fertilizer, of course rice plants will produce good and optimal harvests. Therefore, fertilizing rice plants is mandatory so that the harvest can benefit farmers.
Like fertilizer in general, of course there are several benefits and advantages that Urea Fertilizer offers for rice plants for farmers.
Every plant, especially rice plants, of course needs sufficient nitrogen so that its growth can run optimally.
This is because the nitrogen nutrient contained in Urea Fertilizer is very useful for rice plants. Here are the benefits of urea fertilizer for rice plants, including:
- Makes plant leaves fresher green and contains chlorophyll (green leaves) which plays an important role in the photosynthesis process.
- Accelerate plant growth and development (plant height, number of saplings, number of branches, etc.)
- Able to increase protein content in plants
- Can be used for all types of plants, both food plants, horticultural plants and plantation plants
- With a correct (balanced) and precise fertilization process on a regular and sustainable basis, plants will grow fresh, healthy, and provide multiple yields, and will not damage the structure of the soil used.
Based on the description above, there are many benefits of nitrogen in Urea Fertilizer for rice plants.
Thus, Urea Fertilizer which has a high nitrogen (N) nutrient content of 46% offers many benefits and advantages for rice plants.
Using Urea Fertilizer on rice plants is the right choice for farmers so that their harvests double, making them satisfying and profitable.
Dosage of Urea Fertilizer Use
In general, in rice farming, several types of fertilizer are used simultaneously. According to government recommendations, manure and artificial fertilizer are both needed in rice farming.
There is not only one type of artificial fertilizer used. In general, there are three types of artificial fertilizer used by rice farmers, namely Urea Fertilizer, SP36 Fertilizer (Super Phosphate), and KCl Fertilizer (Potassium Chloride).
If you have a question: what is the ideal fertilizer dose recommended for rice plants? Then there will be many answers to how many doses to give.
Usually, the dose given can differ depending on the type of soil where rice will be planted. However, in general, in accordance with government recommendations, for one hectare of rice fields the recommended dose of fertilizer given is 250 kilograms of Urea, 100 kilograms of SP36, and 75 kilograms of KCl. It could be that, in other rice fields, the fertilizer dose needed is 225 kilograms of Urea, 110 kilograms of SP36, and 75 kilograms of KCl. Again, fertilizer doses can be adjusted to the needs of each agricultural land.
That is the explanation and review regarding the meaning of urea fertilizer: characteristics, benefits and dosage for rice. Hopefully the agricultural products you are working on will gain abundant profits. Hope it is useful.
