Objectif : L’agroforesterie est l’une des techniques permettant d’atténuer les effets néfastes de la dégradation des terres. Cette étude vise à évaluer le potentiel agroforestier de deux espèces de légumineuses Albizia lebbeck (L.) Benth. et Gliricidia sepium (Jacq.) Kunth ex Walp., promues dans l’agroforesterie. Méthodologie et résultats : Pour cela les paramètres physico-chimiques et biologiques des sols sous houppier et hors houppier de Albizia lebbeck et Gliricidia sepium ont été caractérisés. Des tests de comparaison de moyennes, une ANOVA à mesures répétées et une analyse en composante principale (ACP) ont permis de comparer les sols sous houppier et hors houppier des deux espèces. Les résultats montrent que Albizia lebbeck et Gliricidia sepium ont eu un effet positif sur la biomasse microbienne, l’activité respiratoire et la densité de spores des sols (P< 0,05). Albizia lebbeck et Gliricidia sepium ont également induit une amélioration des paramètres physico-chimiques des sols sous houppiers. Conclusion et application des résultats : Ces résultats permettent de conclure que l’utilisation des deux espèces de ligneuses en association avec les cultures garantit une exploitation durable des sols. Ces résultats peuvent servir à améliorer la production végétale en agroforesterie.

Kunth ex Walp. on soil fertility parameters Objective: Agroforestry is one of the techniques to mitigate the negative effects of land degradation. This study aims to assess the agroforestry potential of two species of legumes Albizia lebbeck (L.) Benth. and Gliricidia sepium (Jacq.) Kunth ex Walp., promoted in agroforestry. Methodology and Results: For this, the physico-chemical and biological parameters of the soils under the crown and outside the crown of Albizia lebbeck and Gliricidia sepium were characterized. Comparison of means tests, repeated measures ANOVA and principal component analysis (PCA) were used to compare the soils under crown and outside the crown of the two species. The results show that Albizia lebbeck and Gliricidia sepium had a positive effect on microbial biomass, respiratory activity and soil spores’ density (P Kabore et al., J. Appl. Biosci. 2020 Effet de Albizia lebbeck (L.) Benth. et Gliricidia sepium (Jacq.) Kunth ex Walp. sur les paramètres de fertilité du sol 16079 <0.05). Albizia lebbeck and Gliricidia sepium also induced an improvement in the physico-chemical parameters of soils under crowns. Conclusion and application of results :These results allow to conclude that the use of the two woody species in association with the cultures guarantees a sustainable use of soils. These results can be used to improve crop production in agroforestry. Keywords: soil fertility, agroforestry, Albizia lebbeck; Gliricidia sepium; Burkina Faso

AbstractThe most important measures for salt-affected mudflat soil reclamation are to reduce salinity and to increase soil organic carbon (OC) content and thus soil fertility. Salinity reduction is often accomplished through costly freshwater irrigation by special engineering measures. Whether fertility enhancement only through one-off application of a great amount of OC can improve soil properties and promote plant growth in salt-affected mudflat soil remains unclear. Therefore, the objective of our indoor pot experiment was to study the effects of OC amendment at 0, 0.5%, 1.0%, 1.5%, and 2.5%, calculated from carbon content, by one-off application of sewage sludge on soil properties, rice yield, and root growth in salt-affected mudflat soil under waterlogged conditions. The results showed that the application of sewage sludge promoted soil fertility by reducing soil pH and increasing content of OC, nitrogen and phosphorus in salt-affected mudflat soil, while soil electric conductivity (EC) increased with increasing sewage sludge (SS) application rates under waterlogged conditions. In this study, the rice growth was not inhibited by the highest EC of 4.43 dS m−1 even at high doses of SS application. The SS application increased yield of rice, promoted root growth, enhanced root activity and root flux activity, and increased the soluble sugar and amino acid content in the bleeding sap of rice plants at the tillering, jointing, and maturity stages. In conclusion, fertility enhancement through organic carbon amendment can “offset” the adverse effects of increased salinity and promote plant growth in salt-affected mudflat soil under waterlogged conditions.

Using Data

In most developing countries, climate variabilities and discount rate played an integral role in the decision-making of farmers, which mostly affect their net revenue. Our study employs Ricardian models to empirically verify this hypothesis using data collected from three major agro-climatic zones in Ghana. We particularly estimated the comparative effect of climate change variability, discount rate, and soil fertility; due to trade-off effect of certain farm practices in response to climate change across major climatic zones and also the fact that discount rate becomes an extremely critical issue in formulating and evaluating conservation and management policy to address climate change. The result indicates that discount rate has a positive and significant effect on the farmers’ net revenue. Further, effect of changes in temperature on food crop production and hence net revenue is more felt in the forest and savannah zones. On the other hand, an increase in rainfall has significant negative effects on crop net revenues and whole-farm net revenue, but a positive effect on net revenue of farmers in the savannah zone. We also found a significant increase in soil fertility to increase crop net revenues.

Due to increase in the population which is estimated that the human papulation will increased 9.7 billion in 2050. There is also increase the demands of the food productions. That’s why there is need to solve the problems regarding to the production of the food. Major problem of the food production is the shortage of the land due to the low and bad soil structure and quality of the soil. Soil erosion is one of the main issue which is caused  due to the used of different chemicals, pesticides and fertilizers which are mainly used for the  plant growth and protection but they are the main reasons of the production of the pollution in the soil. There is need of the different new technology for the improvement of the soil structure, quality, its fertility and decontamination of pollution from the soil which are eco-friendly to the environment and have no adverse effect. In this study the role of the different techniques in which genetic engineering, Nano technologies, soil and crop management strategies, integrated pest control management strategies, sustainable remediation techniques, microbial management strategies and the different management stairgates. All these techniques aim to the production of the plants and microbes which are effective against plant disease management. The aim of the use nano agrochemicals and nano sensors for sensing environmental and pathogen conditions against disease management. The aim of the paper to provide the production of the disease resistance plant and the provide balanced nutrients supplements to the soil for the improvement of the soil condition and its fertility. These techniques have economic importance due to the use of the nano agrochemicals which are low cost and have effective and reduce the use of the chemicals substances which have negative effect on the  soil fertility.. There are sustainable remediations techniques also discussed which are used for the decontamination of the soil pollution. In this study the main focus on the improve and increase soil fertility which enhance the growth of the plants as well the production of the crop production. The production of the stress and degradation resistance microbes which is important factor for the protection of the soil from degradation or contamination. All the techniques which are used in this paper have no adverse effect they are helpful in the tolerance of the stress conditions.
