For example, when the spit value is increased, the solubility of iron and manganese in the soil is reduced(128 cell seedling start trays), and phosphorus is prone to precipitate under acidic and weakly alkaline conditions, so its effectiveness is reduced, and flowers cannot be absorbed and utilized. Then find the clarification, which is the soil leaching solution(gallon pot). Phosphorus and sodium combine to increase effectiveness, while calcium, magnesium, and iron decrease effectiveness.

On the other hand, because the pH of the soil affects the activity of microorganisms(128 cell seed starter trays), which affects the changes of certain nutrients, especially those derived from organic matter, such as ammonia. The alkaline earth can be improved with gypsum. If the soil is more alkaline, phosphorus combines with calcium, making phosphorus less effective(seed starting trays). Potassium, calcium, magnesium availability increased with increasing p called.(high quality plastic nursery pots for sale poland)
At the same time, in an excessively high acid-base environment, its acid-base substances will also directly inhibit the absorption capacity of the root system(seed plug trays wholesale). Neutral, acidic, and alkaline soils (pl6~8) are suitable for beneficial microbial activities, which can cause ammoniation. , Confirmation and nitrogen fixation are active, the effectiveness of nitrogen is improved, and the fertility is increased(square grow pots). The effectiveness of phosphorus in neutral soil is high.
Before using the culture soil, and also to incorporate the most insecticidal and sterilizing pesticides for disinfection and sterilization(32 cell seed starting trays). Since natural soil often contains germ spores, pest eggs and living organisms, and weed seeds, etc., the prepared culture soil needs to be disinfected to achieve the purpose of eliminating germs and pests(plastic plant pots wholesale suppliers). The improved potting soil has a soft texture and good air permeability and water permeability, so no cracking will occur.
(high quality plastic nursery pots for sale poland)At the same time, acid fertilizers such as ferrous sulfate and superphosphate are suitable for alkaline soil(105 cell seed starting trays). Most types of potted flowers are suitable for neutral to acidic (p5.5~7.0) soils, because within this limit, the nutrients the flowers and plants need to absorb from the soil are in an absorbable state(plastic plant trays wholesale), which is higher than or higher than Below this limit, some nutrients become non-absorbable, leading to nutrients deficiency in certain flowers.
Improvement method is to mix some thicker matrix and soil components containing a lot of humus in the potting soil(50 cell seed starting trays), such as horse manure after fermentation, repeated fertilizer soil, peat soil, chopped sand, coarse sand, etc. In many parts of northern my country, it is necessary to use a sieve to sieve the wet state into a pellet state(nursery plant pots), the soil is covered, and the groundwater is also alkaline, but most flower plants prefer acid soil, avoid alkaline soil.(high quality plastic nursery pots for sale poland)
The above-mentioned soil is difficult to find in nature(72 cell seedling trays wholesale). If you want to cultivate a good flower, you must manually adjust the cultivated soil according to the ecological habits of the flower and the stage of growth and development. The stronger the soil culture, the lower the effectiveness of boron, manganese, copper, zinc, and clamp(black plastic plant pots). Excessive soluble salts in saline soil and sodium carbonate in alkaline soil have toxic effects on flowers and plants.
