What fertilizer contains nitrogen, phosphorus and potassium
What fertilizer contains nitrogen, phosphorus and potassium? Fertilizer in the three basic elements
In agricultural production, nitrogen, phosphorus and potassium are called the three basic nutrients for crop growth. They are essential for the healthy growth of plants, promoting photosynthesis, root development and fruit expansion. What fertilizers contain nitrogen, phosphorus and potassium? This article will analyze the types and effects of these fertilizers in detail to help you better understand and choose the right fertilizer.
1. Fertilizer in nitrogen, phosphorus, potassium ratio
Common compound fertilizers on the market usually contain three elements: nitrogen, phosphorus and potassium. In different fertilizer formulations, the ratio of nitrogen, phosphorus and potassium will be different to meet the needs of different crops. For example, common compound fertilizers such as 15-15-15, which means that the proportion of nitrogen, phosphorus and potassium each accounts for 15%, are a balanced fertilizer suitable for the growth of most crops. And if you need to promote the flowering and fruiting of plants, you can choose fertilizers with low nitrogen content and high phosphorus and potassium content.
2. Nitrogen fertilizer: promote plant growth
Nitrogen is one of the most important elements in the process of plant growth. It helps the growth and photosynthesis of plant. Fertilizers containing nitrogen are usually in the form of urea, ammonium nitrate, ammonia, etc. Nitrogen fertilizer can provide abundant nitrogen source for plants and help them grow rapidly in the early stage of growth, especially for plants that need a lot of growth, such as wheat and corn. Many fertilizers on the market will indicate that they contain nitrogen, phosphorus and potassium, and fertilizers with high nitrogen content are sometimes used for crops with more fertilizer.
3. Phosphate fertilizer: promote root development
Phosphorus is one of the key elements of plant root growth, and it also plays an important role in promoting plant flowering and fruiting and enhancing plant resistance to diseases and insect pests. Common phosphate fertilizers include calcium superphosphate, diammonium phosphate, monoammonium phosphate, etc. These fertilizers are rich in phosphorus, which can help plants establish a sound root system and enhance soil fertility. When crops enter the late growth stage, especially the stage of flowering and fruiting, the role of phosphate fertilizer is particularly important. Therefore, fertilizers containing nitrogen, phosphorus and potassium will generally make appropriate adjustments in the proportion of phosphorus to meet the needs of crops at different growth stages.
4. Potassium fertilizer: enhance plant resistance
Potassium plays an important role in plant resistance and water regulation. It can not only improve the resistance of plants to diseases and insect pests, but also enhance the adaptability of plants to drought and cold. Common potassium fertilizers include potassium chloride, potassium sulfate and potassium nitrate. In fertilizers containing nitrogen, phosphorus and potassium, the proportion of potassium is generally not lower than that of phosphorus, especially in the mature period of crops. The use of potassium fertilizer helps to promote the expansion of fruits and the accumulation of sugar. Therefore, fertilizers containing nitrogen, phosphorus and potassium usually adjust the potassium content according to the needs of different crops to ensure the overall health and high yield of crops.
5. Compound fertilizer and mixed fertilizer selection
Compound fertilizers on the market usually contain three elements: nitrogen, phosphorus and potassium, which are made by chemical reaction or physical mixing. The advantage of compound fertilizer is that it can provide accurate nutrient ratio according to the needs of different crops. In contrast, mixed fertilizers are made by mixing different types of fertilizers in a certain proportion. For those crops that have special needs for nitrogen, phosphorus and potassium, you can choose a specific ratio of fertilizers. When choosing fertilizers, it is best to fertilize reasonably according to soil conditions, crop types and growth stages to ensure the efficient use of fertilizers.
Conclusion: Choosing suitable fertilizers
In general, what fertilizer contains nitrogen, phosphorus and potassium, the common is all kinds of compound fertilizers, which meet the nutritional needs of crops at different growth stages according to the different ratios of nitrogen, phosphorus and potassium. Nitrogen promotes plant growth, phosphorus promotes root development, and potassium improves plant resistance and fruit quality. When choosing fertilizers, it is recommended to determine the ratio of nitrogen, phosphorus and potassium according to the characteristics of crops and the actual situation of the soil, so as to achieve the best fertilizer benefits, help crops grow healthily and obtain a bumper harvest.
