“…Polthanee et al (1998) also observed that intercropping cassava with one row of pea nuts resulted in highest tuber yields. Similar to the case in the sorghum cropping systems, application of FYM increased tuber yield compared to compost and control respectively due to improved physical and chemical characteristics (Gateri et al, 2006;Fening et al, 2005;Brady & Weil, 1996).…”

“…This may be attributed to the ability of organic inputs to provide plant nutrients and increase nutrient holding capacity of soil, as well as water holding capacity and infiltration rates (Gateri, Muriuki, & Kanyanjua, 2006;Fening et al, 2005). Higher yields were obtained under FYM application compared to Compost as a result of slower decomposition which caused longer lasting effects on soil properties (Brady & Weil, 1996).…”

In this study, the influence of ecological farming practices on soil moisture and yield of cassava (Manihot esculanta Crantz) and sorghum (Sorghum bicolor (L.) Moench) was investigated. The study was conducted in semi-arid Katangi and Ikombe divisions of Yatta sub-county between October 2010 and August 2012. A randomised complete block design with a split plot arrangement was used. ). Intercropping sorghum with dolichos and cassava with pigeon pea + FYM would be a viable strategy to boost crop yields in smallholder farming systems of Yatta sub-county.

“…Furthermore, farmer field level of N and P (0.52 -1.14 and 0.28 -0.76 respectively) in cattle manure was found to be too low for net N mineralisation (Janssen, 1993). Although Fening et al (2008) found refuse soils to contain less contaminants and have adequate nutrient needed by plants in northern Ghana, Agyarko et al (2010) found that refuse soils in southern Ghana were loaded with significant levels of heavy metals higher than background soils. Fening et al (2008) studied potential materials that could be mixed with manure and loamy based soils for safe application in both rural and urban horticulture.…”

“…Poultry manure of varying qualities is used as an amendment in urban horticulture and it is reported to have lower N use efficiency especially in the first year of application (Boateng et al, 2007). Fening et al (2008) identified cow dung and refuse dump soil (land fill soil) as soil amendments that have potential for use in the interior savannah zone of Ghana. But cattle manure is also popular among rural farmers, but when composted it takes a longer period to stabilised and release nutrients (Gomez-Brandon et al, 2008).…”

The search for suitable alternatives to loam, manure and sand based growing media in Ghana has generated a substantial body of literature on potential amendments akin to the peat based media in developed countries. The objectives of this study were to review literature on potential soil amendments in Ghana, determine the reasons for farmer choice of amendments and determine factors influencing farmer adoption of these amendments. Document review and survey were the main methods used in data collection. The review of literature indicates that the research and discourse on soil amendment over the last two decades have largely been limited to land management and nutrient recovery from waste. Although these have largely been reported as successful, they have not addressed the quality issues of soil amendments as finished product for application in specific production systems. As the amendments are not standardized, farmers adopt varying application rates based on their own experiences. Barriers in the use of amendments were found to be the technology to collect, funds to purchase and labour employment. The agro-ecology and the farmers' level of education largely determined the use of particular amendment. The study found wide scale acceptance and adoption of sawdust based poultry litter by urban vegetable farmers, hence the co-composting of sawdust and poultry manure would be the best option that can be developed and standardised for application in urban horticulture. Future research in soil amendment should therefore focus on net N mineralisation, stability indices and the responses of vegetable and ornamental plants to different ratios of co-composting of sawdust and poultry manure.

“…With the current skyrocketing prices of mineral fertilizers, most resource poor farmers would have no other option than to embrace the use of crop residues on their fields. [14] and [5] reported that in agricultural systems in the tropics, there is an increasing interest in using crop residues for improving soil productivity which can reduce the use of external inputs of inorganic fertilizer. These crop residues are in sufficient abundance in farmers' fields at the end of a growing season and play an important role in soil fertility management through their short term effects on nutrient supply and longer term contribution to soil organic matter [10].…”

-Although the use of crop residues to enhance soil fertility has been suggested over the years, little is known about the nutrient composition of these residues as affected by specific nutrient management strategies. A study was conducted at the Soil Research Institute, Kwadaso, Ghana to examine the chemical properties of maize residues after application of different nutrient sources. The study was a field experiment arranged in a randomized complete block design. The treatments considered were application of poultry manure (PM), poultry manure + chemical fertilizer (PM + CF), chemical fertilizer (CF) and a control. Crop residues under CF application recorded the highest total N, P, K contents of 0.90%, 0.14%, and 1.19%, respectively. There were virtually no observable treatment effects on K, Ca and Mg contents of residues. The highest polyphenol (6.90%) and lignin (17.21%) contents were recorded under CF and PM + CF applications, respectively. The polyphenol: N ratios ranged from 7.7 in CF treated residues to 8.3 in residues on control plots. The study indicated that chemical fertilizer treated residues generally have higher nutrients composition and could have faster decomposition rate because of their lower polyphenol: N ratio than residues from all treated and untreated plots.
