| 1 | Influence of Biochar Enriched with Poultry Manure on Nutrient Uptake and Soil Nutrient Changes in Amaranthus Caudatus |
The availability of appropriate and effective fertilizers is one of the limitations of organic and ecological farming in Nigeria. A pot experiment was conducted in a screenhouse to determine the optimum rate of biochar-poultry manure combination for growth and nutrient uptake of Amaranthus (Amaranthus caudatus L.), as well as residual soil nutriens. The study comprised four treatments viz; control, 50% -1 poultry manure and 50% biochar at 10, 20 and 30 tha . The treatments were laid out in a completely randomized design (CRD) with four replicates. Seeds were sown in plastic containers filled with 25kg soil, with a drain underneath. Seedlings were thinned to 2 plants/pot at 2 weeks after planting. Plants were harvested at 6 weeks by ratooning and theregrowths were also harvested after 6 weeks. Soil pH increased -1 with 50% poultry manure and 50 % biochar at 20tha while the organic carbon content was increased with -1 20tha . An increase in soil N, P and K was reflected in increased dry shoot weight and N, P and K uptake -1 with biochar and compost at 20tha application. Application of 50% poultry manure and 50% biochar at -1 20tha gave the optimum Amaranthus nutrients uptake with optimum residual soil nutrient contents which areeffective for ecological farming | Olowoake A.A., Abioye, T.A. and Ojo, | 5:19-26. | Research Article | 2021-12-21 | https://noara.bio/african-journal-of-organic-agriculture-and-ecology/ | |
