Free Ecosystem Services To Help Farmers Managing Crops

European scientists have been developing a web-based tool for farmers so they can see what is available in terms of ecosystem services.

Ecosystem services are free, but often hidden. They include pollination and killing of crop pests by beneficial insects. Now, QuESSA, an EU-funded research …

Success Of New Bug-Fighting Approach May Vary From Field To Field

A new technique to fight crop insect pests may affect different insect populations differently, researchers report. They analyzed RNA interference (RNAi), a method that uses genetic material to “silence” specific genes – in this case genes known to give insect pests an advantage. T…

Microdosing Fertilizer Improves Productivity For Less Money

Crop yields in the fragile semi-arid areas of Zimbabwe have been declining over time due to a decline in soil fertility resulting from mono-cropping, lack of fertilizer, and other factors. In collaboration with the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT),…

Can Insects Help Growing Better Apples?

Apples from trees pollinated by insects are bigger, rounder, and more desirable, according to new research.
The study, led by Dr Mike Garratt, from the University of Reading and published in the journal Agriculture, Ecosystems and Environment, values the annual contribution of insects to two of …

Future Global Crop Yield Projections in Question

About 30 percent of the major global cereal crops – rice, wheat and corn – may have reached their maximum possible yields in farmers’ fields, according to University of Nebraska-Lincoln research published this week in Nature Communications. These findings raise concerns about efforts to inc…

Global Food Production Increased by Changing Harvest Frequency

Harvesting existing cropland more frequently could substantially increase global food production without clearing more land for agriculture, according to a new study from the Institute on the Environment (IonE) at the University of Minnesota.
The study tracked global harvest trends of 177 crops…

Nitrogen Fertilizer Remains in Soils for Decades

Nitrogen fertilizer applied to crops lingers in the soil and leaks out as nitrate for decades towards groundwater — “much longer than previously thought,” scientists in France and at the University of Calgary say in a new study.
Thirty years after synthetic nitrogen (N)…

High Tunnel or Open-field, which System is better For Lettuce and Tomato?

In the mild coastal climate of western Washington, agricultural growers are learning more about the advantages of growing popular fresh-market vegetables in high tunnel production systems. High tunnels can offer many benefits for delicate vegetable crops, including protection from environmental…

LED Lighting Recommended to Enhance Lettuce Quality and Yield

In the life cycle of plants, most developmental processes are dependent on light. Significant biological processes such as germination, shade avoidance, circadian rhythms, and flower induction are all affected by light. Recent advancements in the use of LED lighting in plant and vegetable…
