How can we prevent soil salinization?

图片
What’s Soil Salinization Soil salinization is one of the most vital soil problems for agricultural production. Salinization refers to the salt content of the level affecting agricultural and environmental health. Soil salinization usually occurs in arid areas, In these areas, soluble salt ions accumulate in the soil. In these areas where plant growth requires irrigation, the Evaporation and transpiration process leaves salt in the soil. At the beginning, salt will reduces soil productivity and limits crop yields. As the salt content increases, it kills the vegetation and soil microorganism. As a result, The perfectly fertile soil will became completely barren. Why Does Soil Salinization Occur Several factors contribute to an increase in the amount of salt in the soil: Irrigation Water Quality & Volume The total amount of dissolved salt in irrigated water and its composition affect soil salt content. The more water you irrigate, the salinity of the soil will be

Organic Nematode Control Bio Nematicide by Dora Agri

Damages of nematodes Nematodes attack plant roots, stems and leaves. They are a major group of crop pathogens and cause worldwide losses estimated at about  US$120 billion  every year. They inhabit the soil and damage the roots of plants, weakening their ability to absorb water and nutrients. The symptoms of these damages include stunting, yellowing of plant leaves, and loss of plant vigour. Nematodes rarely killing plants directly, But they will affect plant growth and yields greatly. What’s Dora Nemaxe ? Dora Nemaxe  is a biological nematicide specially for controlling nematodes based on  Paecilomyces lilacinus ( natural Nematophagous fungus )、 Bacillus series  and  organic matter . The effective microbes can control nematodes and inhibit the pathogens of diseases. It parasitize and subsequently kill eggs, larvae and adults of various plant parasitic nematodes. In addition, It’s high content of organic matter greatly improve soil condition, build a good space for roo
