Here’s A Prescription For Scientific Spreading Fertilizer
Chemical fertilizer has a high content of nutrients with a small amount in per unit area, easy to transport, easy to apply, a good effect of increasing yield, fast effect of fertilizer, which can be quickly absorbed and utilized. However, it has single nutrient species, high nutrient concentration and high solubility.In case of direct contact with seeds or roots, seeds burning, seedling burning and improper application of fertilizer may easily occur. Care must be taken when applying seeds and scientific methods must be followed.
Today, we’ll give you a scientific “recipe” for using chemical fertilizer.
Do not water immediately after urea application: urea will soon be changed into ammonium acyl, very easy to lose with water after urea is spread into the soil,therefore, you need not immediately water, and do not use before the heavy rain.Urea can be used as external fertilizer application, which can effectively prevent premature aging of plants due to lack of nitrogen in mid and late stage of crops, but you should pay attention to avoid fertilizer burning.
P fertilizer should not be distributed spread: because of the activity of p fertilizer is little and difficult to be absorbed by crops.
Therefore, when applying phosphate fertilizer, it should be applied as base fertilizer, and applied in seeding ditch or pit more intensively. It is best to mix compost with organic slag fertilizer and reapply in a period of time.
Potash fertilizer should not be applied at the later stage of crop growth: because of the potassium in the lower stem and leaf of crops, it can be transferred to the top of the tender part for reuse.Therefore, potash fertilizer should be applied at the seedling stage or the initial stage of reproductive growth, or as a one-time base fertilizer application.
Ammonium bicarbonate is suitable for deep application: because ammonium bicarbonate is very unstable, it is easiest to decompose into ammonia gas and volatilize, and the higher the temperature, the greater volatile loss, so it is not suitable for use in the greenhouse, nor can it spread on the surface soil, you should carry on ditch application or hole application.
