EFFECTS OF WEED CONTROL METHODS ON WEEDS AND PRODUCTIVITY OF RANGE GRASSES IN SEMI-ARID KENYA
Tropical and Subtropical Agroecosystems, 2023 Background: Weeds are a common occurrence and challenge in different crops eventually influencing crop development and yields. Weed control and management are key in enhancing the productivity of cultivated pastures.

UAS Imagery and Computer Vision for Site-Specific Weed Control in Corn [PDF]
arXiv, 2022 Currently, weed control in a corn field is performed by a blanket application of herbicides which do not consider spatial distribution information of weeds and also uses an extensive amount of chemical herbicides. In order to reduce the amount of chemicals, we used drone based high-resolution imagery and computer-vision techniwue to perform site ...

Functional diversity of farmland bees across rural–urban landscapes in a tropical megacity
Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Urbanization poses a major threat to biodiversity and food security, as expanding cities, especially in the Global South, increasingly compete with natural and agricultural lands. However, the impact of urban expansion on agricultural biodiversity in tropical regions is overlooked.

Agriculture, 2021 Intercropping results in high overall system productivity on a given piece of land due to the efficient use of available plant growth resources. Weed control in intercropping systems is, however, still a challenge. This study focuses on the effect of the

Rarity begets rarity: Social and environmental drivers of rare organisms in cities
Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Cities are sometimes characterized as homogenous with species assemblages composed of abundant, generalist species having similar ecological functions. Under this assumption, rare species, or species observed infrequently, would have especially high conservation value in cities for their potential to increase functional diversity.

Effects of Tertill® Weeding Robot on Weed Abundance and Diversity
Agronomy, 2022 Robotic weed control may reduce labor requirements, soil disturbance, and amount of herbicide applied relative to non-robotic methods. Tertill® is among the first weeding robots to become commercially available. This solar-powered robot moves in a random

Performance Evaluation of Deep Transfer Learning on Multiclass Identification of Common Weed Species in Cotton Production Systems [PDF]
arXiv, 2021 Precision weed management offers a promising solution for sustainable cropping systems through the use of chemical-reduced/non-chemical robotic weeding techniques, which apply suitable control tactics to individual weeds. Therefore, accurate identification of weed species plays a crucial role in such systems to enable precise, individualized weed ...

Fen ecohydrologic trajectories in response to groundwater drawdown with an edaphic feedback
Ecohydrology, Volume 15, Issue 8, December 2022., 2022 Abstract Fens are high conservation value ecosystems that depend on consistent discharge of groundwater that saturates the near surface for most of the growing season. Reduced groundwater inputs can result in losses of native diversity, decreases in rare‐species abundance and increased invasion by non‐native species.

Deep Data Augmentation for Weed Recognition Enhancement: A Diffusion Probabilistic Model and Transfer Learning Based Approach [PDF]
arXiv, 2022 Weed management plays an important role in many modern agricultural applications. Conventional weed control methods mainly rely on chemical herbicides or hand weeding, which are often cost-ineffective, environmentally unfriendly, or even posing a threat to food safety and human health.

Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022 Abstract With the emergence of modern agronomy practices and the use of multiple synthetic pesticide agents to keep control over crop and field throughput, there lies a broad requirement for smart, accessible technologies to track pesticide contaminants in food, water, and other environmental matrices.
