Hazards of Soil Consolidation

Affects the Growth of the Root System

Crop roots need to breathe in the soil, need oxygen, soil caking will affect the permeability, if coupled with heavy watering, the water will press out the oxygen in the soil, the root system can not breathe, there will be compost, the root system also began to necrosis.

When the crop reaches the mid-growth stage, root necrosis will outpace root growth, and the root system will fail prematurely, that is, the root system will become shallower and shallower, especially in old greenhouses. The root system of tomatoes and cucumbers can only go down about 10 centimeters, and more of them become lateral roots that grow down the mulch to the sides. If the root system is dug out, it looks quite long, but in fact the lateral roots are the main ones.

If the root system is too shallow, it affects the ability of the crop to absorb water and fertilizer. When we fertilize with water, regardless of whether it is furrow irrigation or large water irrigation, if the above-ground watering 15 centimeters, normal loamy soil, the water can penetrate to about 50 centimeters. That is to say, a watering and fertilization, within 50 centimeters from the soil, there is both water and fertilizer. However, the crop can only absorb about 10 centimeters on the surface, and after it absorbs the water and fertilizer in the surface 10 centimeters, it will show the symptoms of water and fertilizer deficiency.

Causes Deficiency
Deficiency sometimes does not necessarily mean that the soil lacks this element, but that the root absorption capacity is reduced due to a series of problems such as soil sludge, unsuitable soil pH, or unbalanced soil water supply.
