Why is nutrient soil not easy to take root and sand easy to take root?

When it comes to the maintenance and cultivation of downhill piles, I always recommend that you use river sand to raise piles, and I don't recommend that you use nutrient soil. Many people have similar questions. Why do sand piles take root easily, while nutrient soil does not?

When digging mountain piles downward, most roots only take one main root. The taproot only provides the function of transporting nutrients, but does not have the function of absorbing water and nutrients like fibrous roots and capillary roots. The nutrition of nutrient soil doesn't work. Nutrient soil contains organic matter and inorganic salts. Salt is the most feared thing for the root growth of downhill piles. A flower friend once said that watering flowers with fish water died. I didn't know he raised marine fish until I asked him carefully. Growing up in the sea.

If the downhill pile has many fibrous roots, why can't it use nutrient soil?

"People move to life, trees move to death", long-term field growth, has adapted to the atmospheric environment, soil environment. "Moving trees" will definitely prune and disturb the roots. The root system will lose its absorption of water and nutrients about 15 days after moving. After recovery of absorption, the contents of nutrients and salt in nutrient soil are different. Increased the time for the pile to serve the basin under the mountain.

Advantages of cultivating piles with freshwater river sand;

The first element of soil planted with downhill piles is to be loose and breathable. River sand is looser and more breathable than nutrient soil. Nutrient soil is too delicate and has poor air permeability. Not conducive to root breathing.

River sand is clean, sterile and salt-free. Nutrient soil contains nutrients and salt at the same time, which is not conducive to rooting.

River sand has good drainage. When planting, you can water and spray water on the downhill pile many times. Will not produce stagnant water. Nutrient soil has too strong water retention, and it is wet for a long time after watering, which is not conducive to root respiration and growth.

The river sand in the natural environment dissipates heat quickly, and the temperature difference between morning and evening is large. Conducive to the growth environment of roots. So lure the roots quickly.

Summary: Fresh river sand is the best soil for downhill pile: loose and breathable, no water accumulation, good drainage, aseptic, insect-free and salt-free. This is a good soil for inducing new roots.
