Problems solved by technology

[0007] (3) The leaching effect of acidic soil is strong, and potassium, calcium, and magnesium are easily lost, resulting in the lack of these elements
There are certain deficiencies in these improvers, either they are costly and are non-renewable resources, or they can change the acidity of the soil but at the same time increase adverse phenomena such as soil compaction

Abstract

The invention discloses a soil pH (potential of hydrogen) adjusting method and a soil pH adjusting agent. By the soil pH adjusting method and the soil pH adjusting agent for acid soil improvement, a pH value of soil can be increase from 2-5 to 6-8 to meet the demand of plant growth.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for adjusting soil pH and a soil pH regulator. Background technique [0002] With the emission of automobile exhaust and industrial sulfur dioxide, air pollution is caused, and the acid rain formed causes soil compaction, which is highly acidic, difficult for plant growth, and even causes plant death. The impact of soil pH on nutrient availability is mainly manifested in the following points: [0003] 1. Within the normal range, the reason why plants are sensitive to soil acidity and alkalinity is that the pH value of the soil affects the concentration of various ions in the soil solution, which affects the availability of various elements to plants; [0004] 2. The influence of soil acidity and alkalinity on the availability of nutrients: [0005] (1) Nitrogen is more effective at pH 6-8, because when the pH value is less than 6, the activity of nitrog...
