Manacote™ Controlled release fertilizer

      Manacote™ controlled release fertilizer is a fertilizer with various control mechanisms to delay the initial release of nutrients. And control the amount and rate of release of fertilizer nutrients according to crop demand. So as to keep the release of fertilizer nutrients in line with crop demand. And thus achieve the purpose of improving fertilizer efficiency. At present. The common controlled release fertilizer is film-coated fertilizer. Which means that a film is wrapped around the traditional fast-acting fertilizer granules. And the rate of nutrient diffusion inside the film to the outside of the film. It is controlled through the micro-pores on the film. So as to follow the set release pattern with the same pace of crop nutrient uptake.

1. About Manacote™

Among most of the controlled release fertilizers available on the market. Nagric’s Manacote™, which is the better quality of controlled release fertilizers. That uses a new polymeric organic envelope to encapsulate nutrients and minerals to prevent nutrient loss or volatilization. Not only can it release fertilizer steadily for a fixed period of time to meet crop nutrient demand. While protect roots and leaves from burning. But it has no chemical reaction with soil microorganisms. It saves labor and application costs, and does not require complex equipment. At present, this technology has obtained PCT patent.

2. Release Principle

Manacote controlled release fertilizer release principle is the process of nutrients in the fertilizer from solid to liquid. The rate of release and the law of crop absorption of nutrients. So that when the crop absorbs more nutrients. It will release more, and when less, it will release less, greatly improving the utilization of fertilizer. The controlled release fertilizer than ordinary fertilizer with high technological content. With intelligent controlled release, so it is also called intelligent fertilizer.

So how does controlled release fertilizer control the release of nutrients? To be precise, it is done through a high-tech polymer resin-coated shell. The core of which is a compound fertilizer or a monomeric fertilizer wrapped in a uniform shell. When fertilizer is applied to the soil, soil moisture enters through the membrane pores and dissolves part of the nutrients. Which are then released through the membrane pores.

When the temperature rises, plant growth accelerates, nutrient demand increases, and fertilizer release rate accelerates; while the temperature decreases, plant growth is slow or dormant, and fertilizer release rate slows down or stops. On the other hand. When crops absorb more nutrients, the concentration of nutrients on the outside of the fertilizer granule film decreases. Resulting in an increased concentration gradient inside and outside the film and accelerated fertilizer release rate. Thus aligning the nutrient release pattern with the crop fertilizer demand pattern and maximizing fertilizer utilization.

So how much “membrane” power does the film have? The surface of this film is full of pores that we can not see with the naked eye, the nutrients are released from the inside to the outside of the clothing diffusion, which can greatly reduce the concentration of fertilizer, so that the crop roots get sufficient and appropriate nutrition.

3.  Formulations

All formulations of Manacote controlled release fertilizers have a specific combination of N (nitrogen), P (phosphorus) and K (potassium). With a nutrient release pattern that matches the primary nutrient needs of the plant during the growing season. Moderate amounts of secondary nutrients, such as calcium (Ca) and magnesium (Mg), which can meet specific plant needs or regional conditions. In addition, also we can add small but essential amounts of nutrients such as boron (B), manganese (Mn) and copper (Cu), which can achieve optimal results and uniform development.

4.  Product life

The product life of Manacote controlled release fertilizer will only vary due to soil temperature during application. It will not change due to any other factors such as rain, irrigation, soil composition, soil pH and bacterial life. The higher the temperature, the faster the release of nutrients. When the temperature is lower, the release rate slows down and the nutrient release process continues for a longer period of time. In our tests, testing all products, the temperature is generally at 21°C.

5. Application

It is also a kind of controlled release long-lasting fertilizer, mainly used in indoor, outdoor, potted plants, nursery, garden, hydroponics, sand cultivation, soil cultivation of flowers, vegetables, lawn, fruit trees, forest trees. It is also an ideal and perfect controlled-release long-lasting fertilizer for crops in fields, etc. After the application of this granular controlled release fertilizer coated by polymer resin, the moisture in the soil or substrate causes the granules inside the film to absorb water and swell, and slowly dissolve and spread outside the film, which will release nutrients continuously for 2 to 9 months. The rate of its release is related to the water vapor pressure inside and outside the membrane. It is related to the temperature of the soil and substrate, but is again independent of the water vapor pressure in the soil or substrate when it is saturated with water.

6. Affecting factors

Since the driving forces of nutrient diffusion are temperature and concentration gradients inside and outside the membrane. The release of controlled-release fertilizers changes when the temperature decreases and plant growth becomes slower or dormant. When the temperature decreases, plant growth slows down or becomes dormant, and the controlled release fertilizer slows down or stops releasing. On the other hand, when the crop absorbs more nutrients, the concentration on the outside of the controlled-release fertilizer particles film also decreases quickly, it will increase the concentration gradient inside and outside the film, and the controlled-release fertilizer release rate also follows the change. This will put its nutrient release pattern with the same crop fertilizer demand law, so that the nutrient elements play the maximum fertilizer efficiency or utilization rate.

7. Benefits

Controlled-release fertilizer constantly supply the most direct and effective nutrients according to the needs of plants, to promote the plant leaf color and flower color more vivid, the plant is more robust, seeds or fruit quality better. The rapid release of nutrients from ordinary fertilizers puts plants at risk of root and seedling burning after application. In contrast, controlled release shows its unique advantages. Not only can it be applied once, it can supply nutrients continuously for 3 to 9 months according to the needs of plants, but it is also safe for plants and will not cause root and seedling burning, and is easy to preserve and convenient to use.

8. Precautions

Ith the popularization of it, efficient, environmentally friendly, labor-saving and time-saving product features, people have gradually understood it. Farmers call this “dressed” high-tech products “smart fertilizer”, “fool fertilizer”, in some places, farmers will first choose this fertilizer. However, it is not smart fertilizer with less work, the effect is good, you can achieve the desired results, experts remind, the choice, the application of controlled release fertilizer must be appropriate, scientific. So, as a new type of fertilizer controlled release fertilizer should pay attention to what?

9. Determination of the amount of application

At present, the usual use of film-controlled release fertilizer and fast-acting fertilizer blended fertilizer, the application amount of the first to take into account the type of nutrients, content and the proportion of film-controlled release fertilizer. For example, a blended fertilizer contains only 30% of sulfur-coated urea, the other 70% is a conventional fast-acting compound fertilizer. If we apply film urea can reduce the application of one-third of the amount, then the application of this fertilizer can only reduce the amount of nitrogen in 30% of the film urea one-third of the amount. Only about 10% less than the conventional blended fertilizer, and the proportion of fast-acting phosphorus and potassium with the corresponding increase, because this blended fertilizer Fertilizer only controlled release of nitrogen and no controlled release of phosphorus and potassium.

The target yield of the crop, the fertility level of the soil and the nutrient content of the fertilizer, which control the amount of controlled release fertilizer applied. If the target yield of the crop is high, that is, if the yield level is high or ultra-high, the application amount of controlled-release fertilizer should be increased accordingly. The fertilizer application process must pay attention to the seedling fertilizer isolation, at least 8-10 cm, in order to prevent seed burning and seedling burning. Apply as a base fertilizer and pay attention to mulch in order to prevent nutrient loss.

How it works

All nutrients coated in a novel polymer coating based on organic materials
Soil moisture slowly penetrates through the coating and dissolution the nutrients.
The dissolved nutrients diffuse through the coating to the root zone in predictable time
After the release is complete, the empty shell ruptures and degrades
