Economics of controlling a spreading environmental weed [PDF]
Weeds can cause significant problems to natural ecosystems. Although there have been numerous studies on the economics of weed control, relatively few of these studies have focused on natural ecosystems. This paper addresses this gap in the literature by

ABSTRACT Modern agricultural practices expose humans and the environment to numerous chemical pesticides. Increasing evidence suggests that commercial pesticide formulations may exhibit toxicological properties that differ from those of their active ingredients alone due to the presence of co‐formulants and additives. This study evaluated the cytotoxic

ABSTRACT Background: Grass–clover and silage maize are key for dairy feed production and frequently occur within the same crop rotations. Fertilizer management in grass–clover may leave residual effects that influence both environmental outcomes and the performance of subsequent maize crops.

Organic Matter Quality and Microbial Activity in Soils Managed With Brachiaria Succession
ABSTRACT Background Although succession systems and brachiaria improve soil quality, gaps remain in microbial community dynamics, activity, and soil organic matter stocks. Methods The objective was to evaluate the carbon (C) and nitrogen (N) stocks of soil organic matter fractions and their distribution, molecular characterization, enzyme activity ...

WEEDS AND WEED CONTROL MECHANISM
Weeds are opportunistic plant species that thrive in disturbed environments, often interfering with agricultural productivity and ecological balance. This review synthesizes definitions, classifications, ecological roles, and control mechanisms of weeds, highlighting their dual nature as both problematic and beneficial organisms.

ABSTRACT Background and aim Conservation agriculture (CA) is rapidly gaining traction to promote sustainable crop production, focusing on minimum soil disturbance, permanent soil cover, and strategic crop rotation. Moreover, hydrogel is increasingly being used to improve water retention, including in combination with CA, particularly in water limited ...

Emerging nanoherbicides for next generation of weed control: Strategies and future directions
Weeds represent one of the major biotic stress factors in crop ecosystems, causing approximately 34% reduction in global crop productivity and resulting in an estimated annual economic loss of USD 32 billion.

ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...
