Mechanical-chemical synergy has been proven efficient in weed control. However, characterizing the state of weed–soil complex after mechanical weeding and revealing its effects on subsequent herbicide application is still challenging, which restricts implementation this technology. This paper first presents a method to characterize from perspectives fragmentation composite characteristics. The ...

Weed control automation appears to be a very promising technology based on the tremendous advances in computer processing, machine vision and robotics. Machine systems are size differences between crops weeds or regular structure of crop rows, allowing system recognize plants surrounding weeds. The paper provides description mounted for orienting row cultivator rows its displacement relative tr...

Soybean is the most important oilseed cultivated in the world and Brazil is the second major producer. Expansion of soybean cultivation has direct and indirect impacts on natural habitats of high conservation value, such as the Brazilian savannas (Cerrado). In addition to deforestation, land conversion includes the use of fertilizers and pesticides and can lead to changes in the soil microbial ...

The main objectives of this study were to assess the accuracy of a ground-based weed mapping system that included optoelectronic sensors for weed detection, and to determine the sampling resolution required for accurate weed maps in maize crops. The optoelectronic sensors were located in the inter-row area of maize to distinguish weeds against soil background. The system was evaluated in three ...

Abstract Purpose The application of bio-control plants in the agricultural processes is one effective ways to solve traditional synthetic pesticide residues. This study will investigate effect plant Litsea cubeba branch inter-row cover on soil bacterial community, soil-enriched metabolites, and mineral nutrition tea plantation, which provide a basis for use agroecological farming systems. Metho...

Irrigation has a great impact on global food security as it contributes to the majority of world’s agricultural supply. It is essential judiciously utilize water resources through efficient irrigation management since U.S. groundwater aquifers are rapidly depleting. Thus, quantification relationships between depletion and environmental factors important for understanding crop response varying l...
