Pine needle soil generally means that the black pine needles are naturally dropped, mixed with the soil on the ground. After a long period of continuous accumulation and rainwater irrigation, when the temperature rises, the fermentation turns black, and the pine needle nutrition is decomposed at this time. This is what people call the pine needle soil.
Pine needle soil has the function of heat insulation, moisturizing, soil building and reducing weed growth. Among them, the pine needles of fine needles are fermented by slender leaves. The humus soil contains more humus, light weight, very good permeability of pine needle soil, strong water permeability, contains a lot of organic matter, and has certain pest control. It is widely used as a soil for flower cultivation because it has a disease action such as termites and is acidic or weakly acidic (the acacia mulch is acidic). Linyi Fertilizer Network Copyright

Method 1. In the pine forest in the mountainous area, especially under some primitive pine forests, there is often a pine needle soil which is weathered by the litter of pine trees, which can be directly used. Matters needing attention: When excavating pine needle soil, the surface of the non-corrosion pine needle should be removed, and the light yellow or yellowish brown humus soil should be excavated below. The soft and decomposed special smell is the humus soil, and the humus soil is very thin. Further down is the original soil can not be. Linyi Fertilizer Network Copyright
Method 2: Collect the pine needles and a small amount of soil under the pine trees, place the pine needles and soil in a large plastic bag, keep them moist and keep them moist, and seal the plastic bags and ferment them at a higher temperature. Fermentation in summer for two or three months, if it is autumn and winter fermentation time will be extended; because the pine needles are removed from the surface of the pine, the soil removed is not suitable for flower growth, so it is recommended to use plastic bags to pick up Fully fermented.
