Nitrogen (N) in the agricultural production system influences many aspects of agroecosystems and several critical ecosystem services widely depend on N availability soil. Cumulative changes regional may lead to global environmental changes. Thus, soil status agriculture is importance strategize its most efficient use. also one susceptible macronutrients loss, such as ammonia volatilization (NH3...

This study was conducted to highlight status and distribution of potentially toxic elements (PTEs) in Usangu agroecosystem-Tanzania. The involved 198 soil samples from 10 irrigation schemes including three land use. concentrations selected PTEs (Cd, Cr, Cu, Pb, Zn, As, Hg, Co, Nie etc.) were determined estimate status, distribution, contamination hierarchy. total bioavailable by aqua regia dige...


 Aphids generally attack vegetative plant parts, preferably leaves, and devitalize the by sucking cell sap. Thorough knowledge of pest-predator ecology their interaction is requisite to initiate timely pest management strategies. Therefore, we aimed study population dynamics aphids predators on tomato in Hisar, Haryana during Rabi, 2016-17 2017-18. We observed two dominant aphid species v...

Objective: To identify the role of women in family patio agroecosystem and its relationship empowerment process, two groups municipality Medellín de Bravo, Veracruz, Mexico. Design/methodology/approach: The research carried out is qualitative-quantitative, a constructionist nature, based on Research-Action-Participatory through adaptation management model for natural resource farming. Results: ...

Despite growing concern about transgenes escaping from fields, few studies have analysed the genetic diversity of crops in an agroecosystem over several years. Accurate information about the dynamics and relationship of the genetic diversity of crops in an agroecosystem is essential for risk assessment and policies concerning the containment of genetically modified crops and their coexistence w...

Increasing plant diversity in the perennial phase of pasture-crop rotations is predicted to positively affect belowground productivity and microbial communities and, turn, augment agroecosystem services including soil health carbon storage. Using two grass one legume forage species grown as monocultures combined four intercropped combinations, we evaluated how identity richness influence produc...

Understanding the existing nematode biodiversity is of significant concern because nematodes may divert nutrients from plants and use them for their own development reproduction. The presence diagnostics Filenchus species occurring in southern Alberta have not been addressed previous studies. Herein, we provide a comprehensive characterization adult females four known (F. cylindricus, F. hazene...
