State‐of‐the‐art technologies in precision agriculture: a systematic review

Abstract

BACKGROUND The socio‐economic status of the countries is ever‐changing due to the increasing population. ‘Green Revolution’, a paradigm shift towards technology driven agriculture, has ensured a good quality of life to some extent for this increasing population. However, it brings in several negative impacts on the environment, which poses a threat to the sustainability of agriculture and natural resources. Precision agriculture (PA) is a state‐of‐the‐art concept of site‐specific farm management that helps to overcome this threat in a smart way using modern information and communication technologies. It reduces the indecorous use of resources, pollution and hence improves quality of life, which in turn helps to achieve sustainable development goals. RESULTS The objective of this systematic review is to understand the present status, benefits, and limitations of the state‐of‐the‐art technologies used in PA. A total 67 articles are identified following the PRISMA guideline to inspect the technical innovations at different components of PA. The articles are examined based on the novelties, measured parameters, technologies, and field of applications. CONCLUSION This analysis results in a significant understanding about the present knowledge gap and identification of the potential future research opportunities for sustainable agronomy. © 2019 Society of Chemical Industry

Precision Techniques and Agriculture 4.0 Technologies to Promote Sustainability in the Coffee Sector: State of the Art, Challenges and Future Trends

“…The PA offers several sensing techniques to assist in monitoring crops, allowing the processing of large amounts of data on different parameters [5] enabling the management and selective treatment of fields and farms [53]. PA techniques are especially used to measure and control variables such as temperature, water and soil nutrients [5], and to control the proper use of herbicides, fertilizers and other variables related to agricultural production [56].…”

Autonomous Sensor Network for Rural Agriculture Environments, Low Cost, and Energy Self-Charge

“…They also highlight that the gap between research and practice keeps growing significantly and that efforts to integrate WSNs with existing technologies are much needed. Therefore, understanding the context of efficient sensor networks on agriculture implementation can help provide a general idea of the sector's growing and current status [2]. It is worth mentioning some of the key factors that can heavily influence the growth of this sector, which include reduced energy consumption, reduced costs, data security, scalability, as well as common development platforms and connection protocols [3].…”

Agricultura de Precisão no Brasil: conjuntura atual, desafios e perspectivas

“…Essa nova forma de gerenciamento das lavouras, mediante adoção de fatores à taxa variável, culminou no advento da Agricultura de Precisão (AP), uma vez que, independente do tamanho das áreas cultivadas, conhecer a variabilidade e a qualidade da produção é um diferencial para que os produtores agrícolas possam explorar as potencialidades e as carências de cada lavoura para quaisquer que sejam as culturas cultivadas, ao tempo que reduz os impactos ambientais da atividade agrícola. Essa prática permite o gerenciamento dos recursos agrícolas, preservando o equilíbrio econômico e ecológico, criando assim uma agricultura sustentável (Bhakta et al, 2019).…”
