What is the mechanism of PP weed control fabric to improve soil aggregate structure and nutrition after covering?
The mechanism of PP weed control fabric to improve soil aggregate structure and nutrition after covering is that PP weed control fabric can promote microbial activity and organic matter decomposition.
PP weed control fabric is a type of fabric made of polypropylene, a synthetic polymer that can be woven into various shapes and sizes. PP weed control fabric is widely used to cover the soil surface, control weeds, keep the soil moist and ventilated in gardens and greenhouses. PP weed control fabric can affect the formation, distribution, stability and quality of soil aggregates, which in turn affect the physical, chemical and biological properties of the soil. PP weed control fabric can also change the content, distribution, transformation and availability of different forms of phosphorus in the soil, which affect the fertility and environment of the soil.
PP weed control fabric can reduce the adverse factors of soil erosion, compaction, pollution, etc., and protect the original structure of the soil. PP weed control fabric can increase the proportion of large-sized aggregates in the soil, and improve the porosity, permeability, aeration and water retention capacity of the soil. PP weed control fabric can promote the decomposition of organic matter and the activity of microorganisms in the soil, and increase the content of colloidal substances in the soil, which enhance the cohesion and resistance of soil aggregates.
How does PP weed control fabric improve soil nutrition?
PP weed control fabric can reduce the loss of phosphorus in the soil, increase the storage of phosphorus in the soil, and improve the utilization rate of phosphorus in the soil. PP weed control fabric can change the form of phosphorus in the soil, and promote the transformation of insoluble phosphorus to soluble phosphorus, and increase the content of available phosphorus in the soil. PP weed control fabric can increase the supply of plant-absorbable phosphorus in the soil, and improve the growth and yield of plants, and improve the quality of plants.
PP weed control fabric is a useful tool for improving soil aggregate structure and nutrition, but it is not a magic solution. It has its advantages and disadvantages, and it requires proper use and maintenance. PP weed control fabric can be a good choice for some situations, but it may not be the best option for others. Therefore, one should consider the specific needs and preferences of their plants and gardens before using PP weed control fabric.
