“…Entries in Table 5 reveal major perceived benefits of using organic fertilizer in growing garden egg to be; its environment friendly nature (2.99 ± 1.23) as well as improvement of soil fertility (2.95 ± 1.12). These findings are consistent with previous studies by [16,20,22] that application of organic matter to the soil could also improve aggregate stability and resistance to soil compaction, enhanced fertility and reduced nutrient leaching, increased biological activity, enhance water retention capacity and reduction of greenhouse gases by soil carbon sequestration. Constraints of using organic fertilizer in garden egg production.…”

The study was undertaken to assess organic fertilizer usage by garden egg farmers in Enugu State, Nigeria. The multistage sampling technique was used to select 80 garden egg farmers. Descriptive statistics and multiple regression analysis were used to analyse data for the study. The mean age of respondents was 39 years. Fifty-five percent (55 %) of respondents were married. The majority (97.5 %) of the respondents used farmyard manure while the average cost of organic fertilizer was N57372.73. A lesser percentage (7.5 %) of respondents in the study applied over 2000 kg of organic fertilizer per hectare with 40 % applying twice per season. The perceived benefit of organic fertilizer was: improvement of soil fertility (2.95 ± 1.12), environment-friendly (2.99 ± 1.23). A constraint identified in the use of organic fertilizer was: slow effect (2.12 ± 1.43), Odorous nature (2.06 ± 1.28) and difficulty in the collection and handling of organic fertilizer (2.72 ± 1.03). The study among other things recommends that farmers be granted credits and extension services that will teach them the required skills in the handling and use of organic fertilizer.

“…necessary that we adopt organic farming over chemical fertilizer farming (Usman et al, 2016). Application of suitable rates of N, P, and K fertilisers can boost soil Cu, Zn, and Mn availability, as well as Cu, Zn, Fe, and Mn concentrations in wheat (Li et al, 2007).…”

The present study aimed to assess the physicochemical properties of soil in Faridabad since this region is ahub of industries and agriculture is also practiced. This study was done to analyze any possible impacts ofpollution in soil. Ten sites in Faridabad were selected to determine the soil physicochemical properties.Rice and wheat crops are grown in these agricultural lands from where the soil samples were collected. pH, EC, N, P, K, Fe, Mn, Al, B, water holding capacity and cation exchange capacity were measured in soil samples at two depths (0-15 cm and 15-30 cm). The soil samples did not show any harmful values. The values were within the acceptable range and do not have any sign of pollution in soil. The pH was neutral to moderately alkaline, EC values was <1ms/cm and NPK was mostly in moderate range. Fe, Mn, B and Al were in the acceptable limit and did not have any toxic effects.

“…To increase agricultural productivity, peasant farmers in Nigeria and other Africa countries rely often on the use of organic materials as soil improvers without adequately following the strict guidelines stipulated for the use of these wastes in agriculture; at present, the common organic materials use in Nigeria are compost, cow dung, sheep dung, pig and poultry manures, groundnut cake, Neem cake, human excreta, urine, sewage sludge and unused materials from abattoir [18,27,28]. Table 1 presents the information on the organic fertilizers that were considered for this study.…”

In the quest towards achieving the Zero hunger agenda of the sustainable development goals by 2030, the utilization of organic fertilizers, for soil amendment purposes, has been posited as a feasible alternative for overcoming the negative impacts of inorganic fertilizers. Despite its manifold benefits, the use of untreated and improperly treated organic materials in agricultural production is however capable of introducing toxic metals in the soil-plant systems causing health and agro-environmental impacts. In this study, available organic fertilizers use by Nigerian farmers were selected and analyzed for nutrient values and most importantly, heavy metal contamination. The degree of contamination in each sample was modeled using fuzzy comprehensive assessment. The manure samples possessed optimum nutritional values; the nitrogen, phosphate, and potash contents ranged from 0.91 – 7.44, 0.06 – 1.61, 0.14 – 0.58% respectively. The fuzzy algorithm results categorized all the organic fertilizers as pristine, with a membership degree ranging from 35 to 99%. However, an excessive level of toxic contamination, with a membership function between 3 to 33% was observed. The major contaminants were identified as Zn, Cr, and Cd with an individual contribution of 16, 29, and 33% respectively. Adequate remediation techniques and good management practices that reduce the concentration of heavy metals in the organic fertilizers especially that of Zn, Cr, and Cd, should therefore be promoted among the producers and users of these soil improvers in Nigeria.
