contributions of soil science

Soil, in its interplay of physical, chemical, and biological properties and processes, is a singularly important element. The WBCSD report described an “urgent need to mobilise nature-based solutions to address the challenges of climate change”. Soil Taxonomy in soil classification system uses color, structure, texture and other properties related to soil surface. On average, the carbonate-derived efflux represented 31% of the total CO2 efflux in the six treatments. We reflect upon the recent history of soil mapping efforts in Africa, its importance for smallholder farmers, and what the future holds for this critically important, but often overlooked resource. The early concepts of soil were based on ideas developed by a German chemist, Justus von Liebig, and modified and refined by agricultural scientists who worked on samples of soil in laboratories, greenhouses, and on small field plots. Therefore, precision agriculture, or “farming per pixel” has increasingly become the norm in intensive agriculture. “We must create a two-way street where contributors obtain value by means of increased opportunities for them to process or add value to any data they contribute, as well as to any combined open data”, he said. In addition, a large number of books are being published. What’s more, carbon capture capacities increase when soil health is improved, which in turn can reduce emissions and mitigate some of the effects of climate change. Often, the available soil data is outdated or too broad in terms of geographic location, thus rendering it useless for large and small scale farmers as well as scientists. “In order for this informed decision-making process to work, it needs to involve researchers, development actors, policy makers, as well as the private sector and — of course — the farmers,” agreed the Ethiopia Soil Science Information System’s (EthioSIS) Tegbaru Bellete Gobezie. Once government officials understood this, they adjusted their policy and asked local farmers to buy into it too. Encyclopedia of Soil Science book. However, early keynote contributions to our understanding of indigenous knowledge appeared a little later and include a collection of papers in the IDS Bulletin in 1979 (see especially contributions by Barker, Bell, ... conceptualisations of formal soil science. “Soil salinisation is one of the main land-degrading threats influencing soil fertility, stability, and biodiversity,” the researchers note in their paper. Within the limits of the standard errors of the regression coefficients, CEC of both clay and organic matter increased linearly with pH. He pointed to developments in his own country, Nigeria, where a national agricultural promotion policy (APP) has been implemented to link soil technologies to integrated farming systems and to help smallholder farmers achieve economic and environmental sustainability in producing field crops. Soil plays an important role in farm ecosystem by providing nutrients essential for the growth of agricultural and horticultural crops. EnvirometriX’s Tom Hengl even went as far as depicting spatial resolution as “probably the most important aspect of modern soil information, especially for small-scale farmers.”. This highlights why farmers need a holistic approach in order to reduce chances of loss — soil information can help to improve productivity, but farmers also need tools to help them address non-soil related limits to farm profitability, such as distribution of produce and access to finance. So this process should not only be an academic exercise but also political”, — Vincent Aduramigba, Nigeria Soil Information Service (NiSIS), Invoking his previous experience at NiSIS, he continued: “If the soil is improved and we are able to have specialised fertiliser for our crops, the government can look at the results and see how it benefits them as well.”. There have been numerous large-scale research projects that have aimed to improve crop yields in Africa, however data from such projects is not always easy to access, especially after the research concludes. Agricultural soil science studies the physical, chemical, biological and mineralogical composition of soil by conducting research in soil classification, tillage,irrigation and drainage, plant nutrition,soil fertility and other areas related to agriculture that benefit agribusiness. The classification and nomenclature is based on physical and chemical properties in layers or horizons of soil. These maps at 250 m or 1 km resolution do not match the size of smallholder fields which are often smaller and have mixed land use. However, he also urged private businesses collaboration to focus on early adopters within the local farming community. The overarching consensus among iSDA panelists was that iSDAsoil will serve as a starting point upon which to build and improve local knowledge, local products and local solutions.
