Roles of Fenlong Technology in the Increase of Grain Yield and Construction of a Huge "Underground Reservoir"

Fenlong farming technology was introduced. It has characteristics of very deep tillage and evenly smashing soil,and can evenly smash soil without disturbing soil layers to complete the task of soil preparation. It can be widely used in cultivated land,saline-alkali land,lime concretion black soil,degraded grassland,etc. After the application of the technology in 34 crops in 24 provinces,it can increase yield by 10%-50% and improve quality by above 5%. Fenlong technology can increase soil reservoir capacity,enhance the infiltration rate of rainwater in soil and make " surplus" effect obvious. If the country plans and promotes the technology in 160 million hm^2 of land( including 67 million hm^2 of cultivated land,20 million hm^2 of saline-alkali land,6. 7 million hm^2 of marginal land and 67 million hm^2 of degraded grassland),the total volume of loosened soil in arable land will increase from 198. 1 billion to 840. 0 billion m^3,and the capacity of a " underground reservoir" will increase by 675 million m^3,while natural precipitation reserves will increase by 162 billion m^3. It can effectively solve food security problems and water resource problems such as drought,floods,and industrial,agricultural and domestic water shortages,as well as serious disaster hazards caused by groundwater that has been evacuated in China.

“Physical Fertility” of Fenlong and Its Yield and Benefit Increase

Core theory and acting force("physical fertility") of Fenlong are firstly proposed,and "physical fertility of Fenlong" is relative to the fertility of chemical fertilizer of increasing crop yield. Basic composition of "physical fertility of Fenlong" and its effect of increasing production and improving quality of various agricultural crops are clarified. It makes crop yield increase by 15%-30% without fertilization and 15%-50% by not increasing fertilization amount and irrigation water consumption. It is proposed that "physical fertility of Fenlong" could be sufficiently excavated in the new times of green development. Fenlong has a key significance for rationally reducing chemical fertilizer,soil,water and air pollution,agricultural cost,improving the quality of agricultural products and human health level.

Performance of a Horizontal Flow Constructed Reed Bed Filter for Municipal Wastewater Treatment: The Case Study of the Prototype Installed at Gaston Berger University, Saint-Louis, Senegal

In Saint-Louis, Senegal, a constructed wetland with horizontal flow reed beds (FHa and FHb) has demonstrated significant efficacy in treating municipal wastewater. Analyzing various treatment stages, the system showed only a slight temperature variation, from an influent average of 26.3°C to an effluent of 24.7°C. Electrical conductivity decreased from 1331 mS/cm to 974.5 mS/cm post-primary treatment, with suspended solids (SS) dramatically reduced from 718.9 mg/L to 5.7 mg/L in the final effluent. Biochemical oxygen demand (BOD5) and chemical oxygen demand (COD) saw a notable decrease, from initial levels of 655.6 mg/L and 1240 mg/L to 2.3 mg/L and 71.3 mg/L, respectively. Nitrogenous compounds (N-TN) and phosphates () also decreased significantly, indicating the system’s nutrient removal capacity. Microbiological analysis revealed a reduction in fecal coliforms from 7.5 Ulog/100ml to 1.8 Ulog/100ml and a complete elimination of helminth eggs. The presence of Phragmites and Typha was instrumental in enhancing these reductions. The system’s compliance with the Senegalese standards for disposal into natural environments, WHO recommendations for unrestricted water reuse in irrigation, and the European legislation for water reuse was established. The effluent quality met the stringent criteria for various classes of agricultural reuse, illustrating the system’s potential for sustainable water management. This wetland model presents a robust solution for water-stressed regions, ensuring environmental protection while supporting agricultural needs. The study calls for ongoing research to further refine the system for optimal, reliable wastewater treatment and water resource sustainability.
