项目摘要

The management farmers apply to their land has a significant impact on the health of the surrounding environment and the socio-economic wellbeing of the farmer and their family. A previous Newton Fund project (NUCLEUS) focused on enhancing Nitrogen (an essential plant & soil element) Use Efficiency identified a suite of novel practices, well suited to smallholder famers in northern Brazil, which increased the sustainability and productivity of the tropical agri-systems with low natural fertility. Here we intend to disseminate this new approach more widely which makes use of a variety of ecosystems services to increase crop productivity and soil nutrient use efficiency. These include i) the adoption of a new soil management system (no-till) where farmers avoid the disturbance of soil created by ploughing to retain soil organic matter allowing a more natural, effective soil structure to develop; ii) incorporation of advantageous soil amendments (e.g. leguminous biomass (which adds Nitrogen) and gypsum (which improves soil structure and hence deep rooting); and iii) introducing leguminous trees which enhance soil nutrient cycling and provide added value as a harvestable good. This new approach minimises soil degradation, facilitating repeated cropping of the same area thus removing the need for unnecessary shifting cultivation systems, which have contributed so significantly to deforestation, environmental degradation and poverty via rural to urban migration. To date we have validated this system in partnership with a small network of traditional communities in Maranhao, Brazil by trials on their farms. Now we intend to expand this via knowledge exchange, community events and outreach activities through establishment of new Diffusion Centres (i.e. exemplar farms). By surpassing the barriers which hinder technology uptake by the farmers in the rural community of central-north of Maranhão, we estimate c.150,000 rural families livelihoods can be improved.

管理农民适用于他们的土地，对周围环境的健康以及农民及其家人的社会经济福祉产生了重大影响。以前的牛顿基金会项目（Nucleus）着重于增强氮（必不可少的植物和土壤元素）使用效率，确定了一系列新颖的实践，非常适合巴西北部的小农户名人，这提高了热带农业系统的可持续性和生产力，具有较低的自然可观性。在这里，我们打算更广泛地传播这种新方法，以利用各种生态系统服务来提高作物生产率和土壤养分的利用效率。其中包括i）采用新的土壤管理系统（No-Till），农民避免了通过耕作以保留土壤有机物的土壤灾难，从而可以发展出更为自然，更有效的土壤结构； ii）纳入有利的土壤修正案（例如豆科植物生物量（增加氮）和石膏（改善土壤结构，从而改善了深层生根）；以及iii）引入豆科植物树，从而增强了土壤养分循环并为有害的物有所值提供附加值。这种新方法最大程度地减少了土壤的定义，支持重复的同一区域的裁剪，从而消除了对不必要的转移耕种系统的需求，这对森林砍伐，环境退化和通过大约对城市迁移的贫困产生了重大贡献。迄今为止，我们已经通过对农场的试验与巴西马兰霍的一个少量传统社区网络合作验证了该系统。现在，我们打算通过知识交流，社区活动和外展活动来扩展这一点，以建立新的扩散中心（即示例农场）。通过超越玛兰汉市中部北部农村社区的农民吸收技术吸收的障碍，我们估计C.150,000个农村家庭生计。
