“…The crop at goat manure 5 tons ha -1 , poultry manure 2.5 tons ha -1 and goat manure 2.5 tons ha -1 resulted in reduced OC up to 1.90 %. Similar results are found in a research work carried out by other researchers [2,7].…”

“…Reduced and nonjudicious use of inorganic fertilizers has resulted in low soil fertility, poor soil health and marginalized crop yields. Soil fertility and carbon depletion is common phenomenon in arable fields of tropical and subtropical arid climate [1,2]. In Sindh, abundant organic manures like cattle, goat, farm yard and poultry manure are locally available but are not properly exploited and utilized.…”

“…The boost in poultry production and massive goat breeding has led to abundance of its waste which is not properly managed. Inappropriate disposing off and discarding of these materials cause wastage of organic carbon through CO 2 emission which results in environmental implications [1,2]. However, these resources could be used for restoration of soil fertility, sustained crop production & improve soil health [3,4,5].…”

Soil fertility and soil health are deteriorated owing to indiscriminate use of mineral sources with no organic inputs. However, large volumes of animal manure are available which can be used for nutrient cycling and soil health. A pot experiment was conducted designed in Complete Randomized Design with eight treatments including control and three rates 2.5, 5 and 7 tons ha-1 of poultry and goat manure, each and balanced rate of mineral fertilizers, respectively. It was revealed that both manures applied affected soil organic carbon, Nitrogen, Phosphorus and Potash NPK (75:60:30 kg ha-1), plant height, fresh & dry weight of spinach yield (P< 0.01). The highest values for organic carbon nitrogen, phosphorus and potash contents were obtained when poultry manure was applied at 7 tons ha-1. Manure of poultry at the rate of 7 tons ha-1 significantly influenced organic carbon 1.11%, N 0.055 %, P 6.89 mg kg-1 , K 64.06 mg kg-1 , plant height 37.42 cm, fresh & dry weight 43.31 g and 7.95 g, respectively. In comparison, control treatment resulted in minimum, organic carbon 0.23%, N 0.011 %, P 1.42 mg kg-1 , K 35.23 % and yielded 2.18 g plant dry weight. Comparison of the responses from manures revealed the trend was; Poultry manure > NPK > goat manure. This was largely attributed to differences in organic carbon, N, P, and C/N ratios of the amendments. It is concluded that goat and poultry manure could be applied for soil carbon sequestration sustained crop production and maintain soil fertility & soil health.
