“…This is consistent with the findings of several workers (e.g. Biswas, Roy & Sahu, 1970;Kang, Grimme & Lawson, 1985) demonstrating moisture retention in soils upon green manure addition. Moisture retention in non-incorporated mucuna plots was better than the incorporated plots.…”

The effect of Mucuna pruriens, a herbaceous legume, on some properties of a forest acrisol was examined in RCBD experiment of four treatments: control, NPK fertilizer, mucuna incorporation and mucuna mulch. At flowering, the fresh biomass was cut at soil level, chopped up and applied to the soil either by incorporation or as mulch. In both cases, mucuna improved the physical, chemical and biological properties of the soil. Available soil moisture content increased from 9.54% to values between 10.20% and 11.40% while bulk density reduced from 1.42 to 1.36 Mg m -3. Total N increased from 0.14% to 0.18%. Organic C and K levels did not change while P was slightly reduced. Earthworm populations in the mucuna plots were three times higher than those plots without mucuna. Mucuna suppressed weed growth. These improvements in the physical and chemical properties are indicators of the potential of M. pruriens in enhancing crop yields.

“…Maize and beans are grown in four-meter wide alleys between rows of leucaena trees (Leucaena Leucocephala, see [38] as demonstrated by [39]). Nutrient uptake from air and soil combined with mulching of pruning materials and littered leaves reduce synthetic fertilizer requirement by 50% (based on [38]) and soil organic matter loss by 87% [40].…”

Environmental Assessment of Integrated Food and Cooking Fuel Production for a Village in Ghana

Small-scale farming in Ghana is typically associated with synthetic fertilizer dependence and soil degradation. The farmers often rely on wood fuel for cooking imported from outside the farmland, a practice that is associated with deforestation. Integration of food and energy production may be a holistic approach to solving these issues. We study four approaches to providing food and fuel for cooking in a small-scale farming community. Present practice (PP) of synthetic fertilizer based food production and provision of wood fuel from outside the farming area is compared to three modeled, integrated technology options: integrated food and household-scale biogas production (HH Biogas), integrated food and village-scale biogas production (Village Biogas), and integrated food and wood fuel production (Agroforestry). Integrated approaches are able to eliminate the import of wood fuel, reduce synthetic fertilizer use by 24%, 35% and 44% and soil loss by 15%, 20% and 87%, respectively, compared to present practice. An Emergy Assessment (EmA) shows that integrated approaches are relevant substitutes to present practice considering biophysical efficiency indicated by Unit Emergy Value (in solar emjoules (sej) per J of output) and dependence on renewable inputs indicated by the Global Renewability Fraction (in %): 2.6-3.0ˆ10 5 sej/J and 38%-48% (PP), 2.5-2.8ˆ10 5 sej/J and 41%-46% (HH Biogas), 2.4-2.6ˆ10 5 sej/J and 45%-47% (Village Biogas), 1.7-2.4ˆ10 5 sej/J and 49%-66% (Agroforestry). Systematic recycling and use of local resources may play a pivotal role in reducing the dependence on non-renewable resources in Ghanaian farming, ensuring long-term soil fertility and stemming the current deforestation of wood reserves.

“…Here, optimizing tree density and spacing is a key factor in complementary use of nutrients in these systems, and may be explained in terms of either the competitive production principle or facilitation (Vandermeer 1989). Several mechanisms may be associated with complementary use of nutrients in these systems such as nitrogen fixation since Leucaena is a N-fixing species (Kang et al 1985), or the ability to access different nutrient pools or use of nutrients by the other species that would otherwise be lost to deep percolation. These processes were confirmed from results with herbicide application on the high competition sites (Imo and Timmer 1999).…”
