1. Biochar and/or Compost for Soil Quality and Maize Yield Improvement in an Acidic Ferralsol Soil in Kenya.

The rapidly increasing global population, climate change and dwindling resources have made it very difficult to meet global food demand. To address the issue of food insecurity, sustainable intensification of agriculture (SIA) has been proposed. However, the consequences of poorly managed agricultural intensification can negatively affect the ecosystem. Biochar and compost application has been widely recommended as a highly promising soil fertility replenishment option to promote sustainable ...

2. Mapping spatial variability of soil nutrient deficiencies in smallholder villages – a prerequisite for improved crop production in Africa

Smallholder farming is the dominating type of agricultural production in many parts of Africa. If cultivation practices can be adapted to match the specific needs of individual smallholder plots, this can certainly be regarded as a form of precision agriculture (PA), considering their limited size. A fundamental prerequisite for successful application of PA is the availability of basic information on soil properties at a detailed enough level. To fill yield gaps, site specific information mus... M. Söderström, K. Piikki, J. Kihara, J. Mutua, J. Wetterlind

3. Cashew Trees Detection and Yield Analysis using UAV-based Map

In this study we developed a novel method to detect cashew trees in an orthophoto map derived from images collected by an unmanned aerial vehicle (UAV). We also suggest a way in which these detections can be used to analyse the yield of the cashew farm. The proposed method uses images analysis to find the tops of trees, to merge different tops located on the same tree, and to segment individual tree. The segmented trees are used in a deep learning framework to know the exact location of cashe... T. Bayala, I. Ouattara, A. Visala, S. Malo

4. Implementation of Proximal Soil Sensing, Data Fusion and Machine Learning to Improve Phosphorus Management at a Field Scale

In the context of a rapid increase in phosphorus (P) fertilizers prices, new techniques are needed for geospatial predictions of soil P for improved P fertilizer management, while increasing farmer profitability and reducing environmental concerns. One of the biggest issues in site-specific phosphorus management is the substantial spatial variability in plant available P across fields. This leads to an expensive and laborious process for accurate mapping soil P using a traditional soil sampli... A. Lachgar

21. Analysis, design and development of a web and mobile application for fertilizer olive orchards recommendations

Farmer’s fertilization practices (FFP) in olive intensive or super intensive orchards must be improved to a better control of fertilization costs, to increase olive yielding, to maintain soil fertility and to avoid environment pollution. Indeed, a large category of fertilizer users apply fertilizers arbitrary (66%) without any knowledge about the adequate nutrient requirements of a such planting system. To improve the FFP in intensive and super intensive olive orchards, and in the frame... A. Larbi, H. Boulal, H. El arbi, W. Ben hamouda

22. Enhancing the Use of Appropriate Fertilizers for Improving Rice and Maize Production in Tanzania

Most soils under maize and rice production in Tanzania are characterized by low soil fertility. Fertilizer recommendations were developed in Tanzania to improve soil productivity but most of them are for N and P nutrients. The recommendations do not cover secondary and micro nutrients because the data for these nutrients are very few to establish response functions. In year 2017 to 2019, trials were conducted in 769 farmers’ field in Tanzania to determine soil fertility status and the r... C.J. Senkoro

23. Precision Nitrogen Management in Maize Using an Optical Sensor in the Indo-Gangetic Plains

44. Driving Up Large Scale Irrigated Wheat Yields Through Variable Rate P & K Fertilizer Recommendations in Zambia

Soil types and how these change across a field/farm are the main drivers of yield. Through the surveying of the fields and their subsequent subdivision (virtual) into homogenous zones, Cropnuts has been able to carry out yearly soil sampling within each zone and generate soil correction plans to target the needs of each individual zone rather than applying blanket recommendations. This has led to improved fertilizer efficiency and has had a massive impact on yields of our clients. ... J. Parigiani

45. Decentralized Research: an Opportunity to Accelerate the Transition Towards Sustainable Food Production

The large majority of farmers experiment on their farms to invent and/or adopt new crop production techniques and technologies. This endogenous experimentation process is slow because it often resembles trial and error and relies on minimal data (e.g., comparing total yield between two fields) to draw conclusions. Digital agronomy can help enhance the scientific value of these experiments and thus enable systematic progress toward working solutions. This presentation will discuss the use... L. Longchamps

46. How 20 Years of Precision Agriculture Experience Can Benefit Small Landholders

Most people think only larger farms can benefit from incorporating precision agriculture technologies, when the bigger impact happens with smaller farms. A ten percent increase in crop yield is much more impactful for small land holders for various reasons based upon 20 years’ experience, research, and personal utilization. Incorporating remote sensing, drones, small autonomous robots, and other technologies and practices can help small holders increase yield, crop quality, and free up ... R. Blair

53. Improving Lime and Fertiliser Recommendations for Smallholders Using Co-variate Zoning and Low Cost Mir Soil Testing Technology

Small-holder farmers lack for them affordable access to crop and field specific lime and fertilisation advice. Another challenge is that while crop and region specific fertiliser blends could be produced, high resolution, unbiased and up to date soil information is lacking and thus crop and region specific blends are not produced. As a result, the farmers are left with a small number of available compound and fertiliser blends that often do not match the crop needs. This is not a convincing s... T. Terhoeven-urselmans
