Mixed crop–livestock (MC–LS) farms are assumed to be more environmental friendly than specialized livestock systems, due their better options for internal nutrient recycling. However, there large differences among MC–LS in allocation and Here, we posit that the relative of nitrogen crop compartments, expressed as ratio (CLS), determines performance farms. Among 300 urban peri-urban studied 2014, 42 (Addis Ababa: 20; Jimma: 22) were re-interviewed 2016, using MonQIt (monitoring tool)...

The provision of farmers with proper and balanced fertilizer recommendations is becoming increasingly important, for reasons crop productivity, food security, sustainability. Phosphorus (P) response trials wheat were conducted on Nitisols at 14 sites in the central Ethiopian highlands during 2010 2011 cropping seasons. treatments, comprising six levels P (0, 10, 20, 30, 40, 50 kg ha−1), arranged a randomized complete block design three replicates. Based yield difference between control 90%...

Abstract Rapid urbanization in developing countries is attracting urban livestock farming, which associated with feed nutrient imports and manure accumulations. Here, we report on nutrients (N, P K) production farms Addis Ababa Jimma Ethiopia, estimate recovery these its recycling urban, peri-urban rural crop farms. Estimates were based data from farm surveys, statistics, literature model calculations. Urban had average 13 tropical units positive N, K balances. negative N balances, did not...

Urban and peri-urban agriculture (UPA) is important for food security in fast growing cities of developing countries. UPA also may have an role nutrient re-cycling at the interface rural urban areas. However, little known about this whether it different systems. Here, we report on diversity balances systems three main Ethiopia. Data collected from 425 households (Addis Ababa: 175, Adama: 126 Jimma: 124) were subjected to categorical principal component analysis cluster classify households....

Abstract This study identified decision variables influencing fertilizer adoption and optimal rates among smallholder farmers in the Ethiopian highlands. The use were examined four regional states using a questionnaire survey, which was administered to 2880 farm households. A double hurdle model used analyze factors two independent decisions of fertilizers fertilizers. estimates first revealed that probability increased by 1.2% as household education status improved, 1.4% for an number...

Abstract Boosting the productivity of smallholder farming systems continues to be a major need in Africa. Challenges relating how improve irrigation are multi‐factor and multisectoral, they involve broad range actors who must interact reach decisions collectively. We provide systematic reflection on findings from research project EAU4Food, which adopted transdisciplinary approach for food security five case studies Ethiopia, Mali, Mozambique, South Africa Tunisia. The EAU4Food experiences...

Urban population growth is driving the expansion of urban and peri-urban agriculture (UPA) in developing countries. UPA providing nutritious food to residents but manures produced by livestock farms other wastes are not properly recycled. This paper explores effects four scenarios: (1) a reference scenario (business as usual), (2) increased urbanization, (3) intensification, (4) improved technology, on food-protein self-sufficiency, manure nitrogen (N) recycling balances for different zones...

Improving the productive capacity of lands has been on international development agenda for many years. Yet, to date insufficient progress made. Although there have successes, they tend be limited impact, and spontaneous spreading good practices is low. In this article, different intervention paradigms are reviewed. It concluded that interventions differ in their fundamental view drivers change. We found aim increase total amount nutrients within soil, either through increasing inputs or...

Low soil fertility is one of the main factors causing low agricultural productivity in many developing countries.Despite introduction, implementation and proof effectiveness Integrated Soil Fertility Management (ISFM) as most appropriate approach to alleviate constraints agriculture issues remain a key bottleneck.A element ISFM integrated use organic mineral fertilisers.This study shows that widespread currently hampered by different paradigms (e.g feed plant versus soil), market mechanisms...

In northern Ethiopia, the persistently low crop yield is often attributed to inadequate soil fertility and inappropriate fertiliser recommendations. This study employed Quantitative Evaluation of Fertility Tropical Soils (QUEFTS) model for site-specific recommendations enhance wheat (Triticum spp.) yield. The objectives included quantifying nitrogen (N), phosphorus (P) potassium (K) supplies, modelling observed simulated yields, validating QUEFTS model. experimental trials encompassed four...
