The drought situation in the north of China is severe(72 cell propagation trays wholesale). The application amount of farm manure should be more than 37,500 kg / ha, and the promotion of soil-free manure compost and straw washer should be promoted(110mm plastic grow pots). If it comes into contact with bacterial fertilizer, it will kill the living bacteria in the bacterial fertilizer and lose the effect of increasing the yield of bacterial fertilizer.

The key technologies are as follows: close to the harvest period, not even overnight(sureroot plug trays bulk), the application of dry land fertilization technology based on changing fertilization in spring to autumn, adding organic fertilizer, and scientifically using chemical fertilizer as the main body can generally increase soil water storage 9% -10 %(plastic terracotta pots wholesale), Grain yield can be increased by 40%, and corn yield can be increased by more than 20%.(cheap fabric bags wholesale suppliers poland)
Ammonium bicarbonate, referred to as ammonium carbonate, is also called ammonium carbonate with a nitrogen content of about 17%(72 cell seed trays wholesale). Therefore, in the early 1980s, pilot projects were initiated in northern China, and they have been widely used in Beijing, Shanxi, Shaanxi, Qinghai, Gansu, Ningxia and other provinces(12cm plastic grow pots). This technology is suitable for northern regions where annual rainfall is less than 600 mm and winter temperatures are low.
Bottom fertilizer is mainly organic fertilizer(blow molded nursery pots), phosphate fertilizer and potassium fertilizer all used as the bottom fertilizer, 80% -90% nitrogen fertilizer is used as the bottom fertilizer, and the rest is topdressed in time according to the soil moisture. Combined with the last autumn ploughing, the bottom fertilizer (including organic fertilizer and chemical fertilizer) is applied to the farmland in autumn(120mm plastic grow pots). The suitable fertilization depth is preferably 20 cm-25 cm.
(cheap fabric bags wholesale suppliers poland)It is also used for fertilizing crops such as wheat, corn, millet, and sorghum(7 gallon nursery pots bulk). The formula of heavy nitrogen and phosphorus fertilizer application is determined according to different crops and target yields, the ratio is approximately 1: 0.5-1, and the ratio of corn nitrogen and phosphorus fertilizer is approximately 1: 0.45-0.8(nursery plant pots wholesale). After harvesting summer wheat with high-quality organic fertilizer, plant short-term green or economic green manure.
The temperature is relatively stable below 20 ° C(bulk 10 gallon pots). If the temperature of wheat nitrogen or phosphorus fertilizer is slightly higher or the moisture content in the product exceeds a certain standard, ammonium bicarbonate will decompose into ammonia and carbon dioxide, and the gas will escape in the air, causing a loss of nitrogen fertilizer efficiency(wholesale nursery supplies plastic pots). There are six taboos when using ammonium bicarbonate, and have ammonia smell.
Fertilization methods and soil management directly affect soil moisture and crops' utilization of water and fertilizer(bulk 14 gallon pots). Foliar spraying of ammonium bicarbonate is highly corrosive to crop leaves, and it is easy to burn the leaves and affect photosynthesis, so it cannot be used as foliar spraying fertilizer(plastic plant pots bulk). Avoid mixing ammonium bicarbonate with alkaline fertilizers. Pure product is white powder crystal, industrial supplies are slightly off-white.(cheap fabric bags wholesale suppliers poland)
Dry farming fertilization technology(bulk 15 gallon pots). It can be dissolved only when ammonium bicarbonate is applied when the soil has a certain humidity. If it is mixed with alkaline grass ash, lime, etc. or applied at the same time, the fertilizer effect will be lost, so ammonium bicarbonate should be applied alone(plastic hanging baskets wholesale). Avoid mixing ammonium bicarbonate with bacterial fertilizer and it will emit a certain concentration of ammonia gas after application.
