Ways to improve fertilization efficiency

How to apply fertilizer scientifically?How to increase production and revenue at the lowest cost?How to improve fertilization efficiency?These are the most important issues that farmers care about. Below, I will introduce some methods to improve the efficiency of fertilization.
How to improve fertilization efficiency
A, see temperature according to the practice for many years, at 0 ℃ to 32 ℃, absorb the amount of fertilizer, crop velocities was positively correlated with soil temperature, lower than 0 ℃ or higher than 32 ℃, crop fertilizer absorption ability decline gradually.Therefore, in the low temperature season, the crops over the winter can be applied with semi-mature organic fertilizer and high concentration of water manure, so that it can provide heat in the decomposition process and improve the earth temperature.Phosphorus and potash fertilizer can also be applied in a moderate amount to enhance the cold resistance of crops over the winter.Rapid nitrogen fertilizer can also be applied to facilitate rapid uptake of crops.When the hot season comes, apply plenty of ripe organic fertilizer, apply appropriate amount of fertilizer, and release fertilizer by water.It is also necessary to avoid the meeting of water and fertilizer peak, causing crops to flourish in the early stage and decline in the late stage.
(1) apply more nitrogen fertilizer in places with good lighting conditions to promote the nutritional growth and reproductive growth of crops;In places with poor lighting conditions, less nitrogen fertilizer should be applied to prevent crops from greying and late ripening.(2) when the light is strong, apply fertilizer deeply to prevent photolysis and volatilization. Apply more phosphorus and potassium fertilizer to improve water utilization rate.(3) as the leaf area coefficient of crops increases, fertilizer should be applied appropriately, but it should be applied in the morning and after 4 PM to reduce consumption.

Three, because of different rainfall and water resources, there are also differences in fertilization technology.(1) excessive nitrogen fertilizer should not be applied in rainy season. The first is to prevent crop growth, the second is to prevent fertilizer loss, and the third is to prevent water pollution.(2) in the dry little rain, should right amount increasing p, k, increasing potassium fertilizer can improve the drought-resistant ability, increasing phosphate fertilizer can improve the utilization of the water, and be able to play the role of nitrogen to phosphorus increased.(3) in terms of the operation method, it should be noted that, when the soil has the highest water content, it is advisable to apply heavy and light fertilizer, i.e., the fertilizer concentration is high, but the dosage should be small, and keep a certain distance from the crops and plants.When the weather is dry, appropriate light fertilizer heavy application, or fertilizer less water more, increase watering times.
The effects of gases in the air, soil and atmosphere on the application of fertilizers are also greatly affected.When the soil is compacted, or the water content is too high, the space of the soil is small, the gas is difficult to circulate, the respiration of the root system is inhibited, the decomposition of nutrients by microorganisms is hindered, and the ability of fertilizer supply is decreased.Therefore, in agricultural production, the first thing is to keep the soil loose and the air flowing normally.Second, control the amount of fertilization, especially the amount of bottom fertilizer.Third, we need to open the ditch well in the field, so that precipitation can be discharged, infiltration, rain stop the field dry.
These are some ways to improve the fertilization efficiency. After you know it, you can apply fertilizer reasonably according to the actual planting conditions.
