Fertilizers enhance the growth of plants. This goal is met in two ways, the traditional one being additives that provide nutrients. The second mode by which some fertilizers act is to enhance the effectiveness of the soil by modifying its water retention and aeration.
Fertilizers typically provide, in varying proportions:
three main macronutrients (NPK):
1.Nitrogen (N): leaf growth
2.Phosphorus (P): development of roots, flowers, seeds, fruit
3.Potassium (K): strong stem growth, movement of water in plants, promotion of flowering and fruiting
NPK 15-5-25 available in MOP-based, SOP-based, and Nitrate-based forms, is a versatile fertilizer beneficial for various crops, providing Nitrogen and Potassium, promoting plant growth, flowering, and fruiting.
Promotes leaf growth through assistance in chlorophyll synthesis, resulting in rich, green foliage .
Essential for root growth, encouraging flower and fruit production, and facilitating energy distribution within the plant.

Is There Any Harm in Using NPK Fertilizer?
There is no harm in NPK fertilizers in conscious use. However, fertilization without soil analysis may cause the reintroduction of sufficient minerals to the soil, and an excess of some elements may cause a problem.
With regular analysis, applying a sufficient amount of NPK fertilizer does not cause any harm to our farmers. For these reasons, NPK fertilizer can be used in every geography from South Korea to Egypt in accordance with all climatic conditions.
1) The particles are small, uniform, and not easy to harden.
2) The product quality is stable, easy to distinguish from ordinary fertilizers, and has a high degree of identification.
3) Low water content, good water solubility, fast melting speed, suitable for cultivation in various facilities.
4) Nutrients are evenly distributed, which improves the utilization rate of fertilizers and significantly increases production and income.
5) Rich in nitrate nitrogen and ammonium nitrogen, it dissolves quickly, absorbs quickly and takes effect quickly.
6) The production process is clean, green, and environmentally friendly.
--- No nutrient segregation - All nutrients are contained in every prill or granule so there can be no risk of nutrient segregation during shipping, handling or spreading
--- Even nutrient application - All nutrients are applied evenly to the whole crop avoiding uneven application and yield losses
--- Range of nutrient ratios - A wide range of N:P:K + S ratios and availability of formulas with secondary and micronutrients ensure there is a fertilizer for all crop situations
--- Additional nutrients - MINGYU fertilizers also contain micronutrients essential for specific crops. These may include boron, iron, manganese, molybdenum, zinc etc
The difference between SOP (Potassium Sulphate) based fertilizer and MOP (Potassium Chloride) based fertilizer:
Potassium sulfate (K2SO4) and potassium chloride (KCl) are two common potassium fertilizers that have some differences in their chemical composition and mode of action.
Chemical composition: Potassium sulfate: Potassium sulfate contains potassium (K) and sulfur (S), of which the content of potassium is usually higher, is one of the main components of potassium sulfate fertilizer. Potassium chloride: Potassium chloride contains potassium (K) and chloride (Cl), of which the content of potassium is also higher, is one of the main components of potassium chloride fertilizer.
Mode of action: Potassium sulfate: Potassium sulfate provides two essential elements of potassium and sulfur for plants to absorb and use. Potassium is a key element needed for plant growth and development, promoting root development, improving disease resistance and increasing yield. Sulfur also plays an important role in protein synthesis, plant growth and nutrient absorption. Potassium chloride: Potassium chloride also provides potassium for plants to absorb and use. Chloride plays an important role in photosynthesis and ion balance in plants, but not all plants have the same requirements for chloride. Some plants are allergic or intolerant to chloride, so potassium chloride may not be the preferred potassium fertilizer in these cases.
Soil and crop suitability:
Potassium sulfate: Potassium sulfate is suitable for most soil types, especially alkaline soil, because potassium sulfate can also help improve the acidity of the soil. It is suitable for many crops, including grains, vegetables, fruit trees, etc.
Potassium chloride: Potassium chloride dissolves easily in soil and is suitable for a variety of soil types. It is also suitable for many crops, including corn, potatoes, vegetables, etc. However, for some chlorine-sensitive crops (such as strawberries, peanuts, etc.), the use of potassium chloride may need to be cautious.
There are some differences between potassium sulfate and potassium chloride in chemical composition, mode of action and applicability. When choosing which fertilizer to use, you need to consider the chloride requirements of the plant, the soil type and other factors.
When using nitrogen, phosphorus and potassium fertilizer, the following points need to be noted:
Understand fertilizer composition and content. Different plants have different requirements for nitrogen, phosphorus and potassium, so the appropriate fertilizer should be selected according to the needs of the plant.
Choose the right time and way to apply fertilizer. Fertilization time is generally in the critical period of plant growth, such as flowering, fruit, growth period and so on. The fertilization method can be hole application, strip application, irrigation and fertilization, etc., the specific way should be selected according to the needs of plants and soil conditions.
Apply fertilizer properly. According to the needs of plants and soil conditions to determine the amount and frequency of fertilization, to avoid excessive fertilization, so as not to cause excess or deficiency of plant nutrition.
Mixed fertilization. Pay attention to the selection and collocation of fertilizers, but also pay attention to the use of other fertilizers or organic fertilizers, in order to give full play to the fertilizer effect and improve the growth rate and yield of plants.
Follow scientific fertilization principles. That is, "appropriate, timely, appropriate method", on the basis of following the scientific principle of fertilization, the reasonable use of nitrogen, phosphorus and potassium compound fertilizer can better promote the growth of plants and increase the yield.
Nitro-compound fertilizer is a high-concentration N, P and K compound fertilizer produced by adding phosphorus, potassium and other compound fertilizer materials with ammonium nitrate as nitrogen source. Its products contain both nitrate and ammonium nitrogen. The main products are ammonium nitrate phosphorus, ammonium nitrate phosphorus potassium.
Nitro-compound fertilizer is an important agricultural fertilizer, which is mainly suitable for cash crops such as tobacco, corn, melons and fruits, vegetables and fruit trees, as well as alkaline soil and karst landform areas, and its application effect is better than urea in alkaline soil and karst landform areas.
Different plants have different preferences for nitrate and ammonium nitrogen. Calcium-loving plants that are suitable for growing on calcareous soil with high pH value preferentially use nitrate nitrogen, such as corn and most vegetables, cotton, tobacco, fruit trees, etc., are also cash crops that prefer nitrate nitrogen. Calciphobe plants suitable for acidic soil and plants suitable for low REDOX potential soil are fond of ammonium nitrogen. Under the condition of controlling the ratio of different nitrate nitrogen and ammonium nitrogen, the vegetable cultivation experiment was carried out. The relative yield of all nitrate nitrogen was 100%. When the ratio of ammonium nitrogen exceeded 30%, the vegetable would be reduced, and the yield of all ammonium nitrogen was less than 20% of all nitrate nitrogen. In the book Vegetable Cultivation in China, it is clearly pointed out that "vegetables are nitrin-tolerant crops, and when the amount of ammonium nitrogen exceeds 50%, the yield of onion decreases significantly, while spinach is more sensitive to ammonium nitrogen and has the highest yield under the condition of 100% nitrate nitrogen."
As base fertilizer
When the nitro-compound fertilizer is used as the base fertilizer in dry fields, it is necessary to cover the soil deeply to reduce the crystal fixation of potassium, and to facilitate the root absorption of crops and improve the utilization rate.
As topdressing fertilizer
Since potassium is less mobile in the soil, it should be concentrated in strips or holes to the soil layer with dense roots to promote absorption.
Before-and-after comparison
Multipurpose: Drip irrigation and sprinkling irrigation or foliar spray, the nutrients can be absorbed directly and rapidly by the crops, and quickly relieve the nutritional deficiency. The efficiency of the fertilizer can be maximized.
