The influence of organic amendments on soil aggregate stability from semiarid sites [PDF]

open access: yes, 2016
Restoring the native vegetation is the most effective way to regenerate soil health. Under these conditions, vegetation cover in areas having degraded soils may be better sustained if the soil is amended with an external source of organic matter.

Information flow and the adoption of soil‐improving and water conservation measures, and household welfare: Insights from a randomized controlled trial in Uganda

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Extension services are designed to facilitate the flow of information from researchers to farmers. However, information failures continue to impede the diffusion of soil‐improving and water conservation technologies in Sub‐Saharan African countries. We use a randomized controlled trial (RCT) to examine the impact of an extension‐based campaign

Evaluating Syrphid Fly Predation on Aphids Under Controlled and Field Conditions in High Tunnels: A Comparative Study With Lacewings

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Biological control in high tunnel systems can be optimised by matching predator species to seasonal environmental conditions. We evaluated the predatory efficacy of syrphid flies (Toxomerus marginatus (Say), Eupeodes americanus (Fabricius)) and lacewings (Chrysoperla carnea (Stephens), Chrysoperla rufilabris (Burmeister)) across laboratory ...

Impact of organic mulch and exposure to shallow groundwater levels on Cnidoscolus aconitifolius in a tropical wetland, South Sumatra, Indonesia

open access: yesLilloa
Agricultural land in Indonesia is decreasing due to its conversion for various non-agricultural interests, which are economically more profitable. The remaining land available for agricultural activities is a suboptimal wetland.

Embedded Pesticide Use: Exploring the Pesticide‐Land Nexus

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT Since the turn of the century, global land grabs, farmland financialization and land‐based food sovereignty movements have returned the land question to the heart of agrarian studies. Meanwhile, abiding interest in pesticides has been reanimated in the face of changes in production, regulation and knowledge of toxicity.

Agricultural practices shape microbial communities and change fresh and soil organic matter mineralization in a tropical soil : S11.07-P -1 [PDF]

open access: yes, 2012
Priming effect (PE) is defined as a stimulation of the mineralization of soil organic matter (SOM) due to fresh organic matter (FOM) supply. This process leads simultaneously to a loss of carbon to the atmosphere and to a remobilization of nutrients.

Weed Control with Straw Residues in Occasional Direct Seeding of Faba Bean (Vicia faba sp.) in Organic Agriculture [PDF]

open access: yes, 2010
In order to gain momentum in the consolidation process of no-tillage systems in Europe’s Organic Agriculture, occasional direct seeding (DS) of faba bean (FAB) into a mulch layer of residues from precrop oats should be scrutinized.

Multivariate trait profiling and genetic diversity in a global foxtail millet germplasm panel

open access: yesPlant Biology, EarlyView.
Four elite foxtail millet groups discovered from 260 accessions: perfect for breeding climate‐resilient, high‐yielding dual‐purpose crops. Abstract Foxtail millet (Setaria italica L.), known for its climate resilience and dual‐purpose utility, is underutilized in breeding programs despite its agricultural potential.
