Optimization of treatment parameters for the use of FLYASH amended composts for plant growth
- Savannah State College, GA (USA)
In continuation of the authors efforts to utilize coal fly ash as an amendment to organic manure for vegetation, four parameters such as the nature of the manure, plant-type, ash to manure and soil to amended compost ratios were investigated. a high grade organic manure, Gotta Grow, and a low grade manure, compost-manure, compost-toast, (Bricko Farm products) along with a home-made composed were used to make fly ash-amended composts. Four plants, collard green, mustard green, corn and sorghum were selected for study under greenhouse conditions. Keeping other variables constant, the fly ash to manure ratio was changed from 0 to 60% FA, and compost to soil ratio from 0 to 25%. The plants were grown for approximately 8 weeks and harvested. The plant yield was measured both before and after drying. It was found that out of four plants, yield from corn is the highest when fly ash-amended compost-toast (20% FA) was used at a compost to soil ratio of 1:3. The plant samples are being analyzed for major and minor elements including boron which is detrimental to the growth of plants.
