To fertilize the degraded soil, applying 10 kg of fulvic acid biocide and 170 kg/mu of straw matrix can significantly improve the quality of soil arable land, increase soil looseness, enhance water retention and fertility, and increase soil organic matter content. After consecutive years of application, the soil fertility can be increased by 0.5 grades, the soil degradation can be effectively repaired, and the soil nutrients caused by soil degradation can be fixed and lost, and soil re-penetration diseases can be significantly improved. The crops recovered, the plants were robust, the leaves were thick and green, and the yield and quality were significantly improved.
The acidified soil was improved and the application of humic acid bio-organic fertilizer at the end of 200 kg/mu resulted in an increase in the pH value of the soil with an increase of 14.19%. The degree of acidification was significantly reduced, and the soil compaction and lack of crops caused by acidification were significantly improved. improve. After successive years of application, the acidified soil was well restored, the rot and roots of the crop were significantly reduced, the root system was developed, the plants were robust, and the growth was strong, and the yield and quality were improved.
Saline-alkali soil improvement, applying 20 kg of fulvic acid bio-agent and 20 cubic meters/mu of straw substrate, can significantly ease the degree of soil salinization, and improve the phenomenon of dead seedlings and immature seedlings, and increase yield. After consecutive years of application, the phenomenon of loose soil, no compaction, enhanced water retention and fertility enhancement, robust plant crops, strong resistance to disease, and increased yield and quality.
