Description

ACTIVE AND ENHANCED EFFICIENCY FERTILIZER ADDITIVE AND ACTIVE AND ENHANCED EFFICIENCY FERTILIZER TECHNICAL FIELD

[01] The present disclosure relates to the technical field of the fertilizers, and specifically relates to an active and enhanced-efficiency fertilizer additive and an active and enhanced

efficiency fertilizer.

DEFINITION

[02] In the present description and claims, the term "comprising" shall be understood to have

a broad meaning similar to the term "including" and will be understood to imply the inclusion of

a stated integer or step or group of integers or steps but not the exclusion of any other integer or

step or group of integers or steps. This definition also applies to variations on the term

"comprising" such as "comprise" and "comprises".

BACKGROUNDART

[03] Studies in recent years demonstrate that in some areas of China, the organic matter in the

soil is reduced, and the soil is hardened. And there is a law of diminishing returns in the

relationship between fertilization and yield. The more fertilization, the lower the utilization rate

of the fertilizers, and the lower the yield of crops increased per unit of fertilization. The excessive

fertilization may even cause the yield reduction and environmental pollution. The main reasons

resulting in the above situations are as follows: 1. the technical content of fertilizer products is

low; 2. the level of fertilization technology is low; 3. the soil is hardened, with poor water and

fertilizer retention effects; and 4. the growth of crop roots is weak, affecting the absorption and

utilization of nutrients.

[04] Due to the excessive use of fertilizers, some of the nutrients such as nitrogen and phosphorus that are not absorbed by crops permeate into the groundwater, leading to groundwater

pollution, for example, excessive nitrite in the groundwater, which could seriously threaten the

safety of humans and animals. Some of the nutrients enter the surface waters through surface

runoff, resulting in the eutrophication of the surface water. Many toxic and harmful substances

such as heavy metals infiltrate the soil, causing environmental pollution. Ecological deterioration,

such as soil salinization, soil hardening, severe weather, and the like, causes the quality of the

cultivated land to decline, affecting the normal growth of crops, and reducing the quality of crops.

Therefore, it would be beneficial to develop an active and enhanced-efficiency fertilizer that can

not only increase the production of chemical fertilizers, but also overcome the deterioration of

the physical and chemical properties of the soil and the soil pollution which are caused by the

long-term application of the chemical fertilizers. This would help to develop an environmentally

friendly fertilizer capable of improving the quality of the soil, increasing the yield and quality of

crops.

[05] Currently, plant growth regulators, such as naphthaleneacetic acid, sodium nitrophenolate, and gibberellin, are added to commercial fertilizers, to promote the growth of crops. However,

without the limitations of the standard, the market is chaotic, and the regulators are misused,

affecting the quality and safety of crops. In 2019, related administration departments of China

formulated a standard to limit the addition of plant growth regulators to fertilizers. However, it is

encouraged to add synergists, such as biostimulants, to the fertilizers to improve the utilization

rate of the traditional fertilizers.

an active and enhanced-efficiency fertilizer, which may ensure various nutrients required for the

growth of crops, promote the growth of crop roots, improve the resistance of crops, loosen the

[42] 2.5 Test method

[43] The field was in a three-row arrangement with walkways between repetitions, surrounded

by protection rows. The arrangement adopted the randomized block design, replicating 3 times.

The area of each block was 3.6x5.55=20 m2 , with row spacing of 60 cm. There were 6 rows for

each block in the east-west direction. 2 rows of the crops were manually harvested to calculate

the yield.

[44] The field management was carried out in accordance with the requirements of high-yield field. The stalk was returned to the field, and the rotary tillage rake was applied. Fertilization and

sowing were performed in different treatment blocks on June 17, and the density was designed to

be 5000 plants/mu. The establishing seedlings was performed on July 11. The micro-spraying

was performed on June 20 for 40 min, and the topdressing was performed on July 29. And 150 g

of "Yuba" (25% nicosulfuron with atrazine) per mu was mixed with 30 kg of water to spray for

weeding on June 27. The control of the crop borers and aphids was performed on July 15. The

crops were harvested on October 5.

[50] 3.2 The utilization rate of fertilizer

[51] The utilization rate of fertilizer refers to the percentage of the amount of nutrients

absorbed by the crops from the applied fertilizer to the total nutrients in the fertilizer. The

utilization rate is an important indicator for evaluating the fertilizer loss. The higher the utilization

rate, the lower the loss rate. In the present example, the agronomic utilization rate of fertilizer

was calculated based on the absorption of 3.43 kg of N per 100 kg of grain by the difference

method:

R= (Yield after fertilizat ion - Yield in nutrient deficient areas) x Absorption per 100kg of grain Applicatio n amount of fertilizer x 100
