Illinois' crop-counting robot earns top recognition at leading robotics conference

Researchers at the University of Illinois developed a robot called TerraSentia to count corn plants with high accuracy. The robot uses a suite of sensors, algorithms, and deep learning to capture each plant from top to bottom, overcoming challenges such as varying inter-plant spacing.

First step to lasting wheat health

Rothamsted Research has developed a new approach to protecting wheat crops from the devastating take-all root fungus, by carefully selecting the first wheat variety in a cropping cycle. This reduces the disease's severity and increases yields in subsequent crop varieties.

Long-term study shows crop rotation decreases greenhouse gas emissions

Crop rotation has been shown to decrease greenhouse gas emissions by up to 35% compared to continuous corn or soybean. Rotating crops also increases yield benefits of over 20%, with tillage not affecting emissions. The study highlights the importance of crop diversification and soil management in reducing environmental impact.

Policy driver of soil organic carbon accumulation in Chinese croplands identified

Chinese croplands experienced drastic changes in management practices since the 1980s, leading to increased soil organic carbon (SOC) accumulation. The study found that economics and policy-driven organic inputs dominated SOC sequestration, particularly through crop straw/stover return policies.

Faba fix for corn's nitrogen need

Researchers found that faba bean cover crops can add a significant amount of nitrogen to the soil, reducing the need for commercial fertilizer by up to half. The timing and management of faba bean residues also play a crucial role in maximizing the benefits of this practice.

Corn hybrids with high yields come with more variability

A new study evaluated 101 commercially available elite corn hybrids for their yield stability and crop-management adaptability. The researchers found that hybrids with stable yields under varying conditions are less responsive to environmental factors, while those with high adaptability yield well in optimal conditions but may perform ...

Satellites, supercomputers, and machine learning provide real-time crop type data

A new technique uses satellite data and machine learning to distinguish between corn and soybean fields in Illinois, providing accurate crop type data every two months. The researchers used Landsat satellites and a deep neural network to analyze the data, showing promise for future innovations in agricultural applications.

Natural enemies reduce pesticide use

A study found that increasing crop diversity in agricultural landscapes reduces aphid populations and decreases the need for pesticides. This is because natural enemies of aphids, such as ladybirds and spiders, have better living conditions in diverse landscapes.

Weeds out of control

A nationwide study found that black-grass populations in England have evolved resistance to herbicides, leading to increased costs and lower crop yields. The research team recommends adopting weed-management strategies that rely less on chemicals.

Rust stemmed for wheat

A team of experts has identified a gene that triggers resistance in wheat to the devastating fungal pathogen Puccinia graminis f. sp. tritici (Pgt). The breakthrough allows for DNA testing to identify whether a rust strain can overcome a resistance gene, enabling targeted treatment and reducing crop devastation.

Quantifying the greenhouse gas footprint of crop cultivation

A new study proposes a generic methodological framework to accurately quantify the greenhouse gas footprints of crop cultivation systems. The framework takes into account direct and indirect contributors, providing example values of emission factors and emphasizing the combination of measurements and model simulations.

Hitting the bull's eye on crop nutrient requirements

Researchers from Aarhus University have developed a method to match crop nitrogen requirements with a precision of 10-20 kg N/ha. This method uses a reference curve based on comparisons of leaf area and leaf reflectance at different light wavelengths, allowing for more accurate nitrogen application and reducing agricultural emissions.

Extreme weather conditions and climate change account for 40 percent of global wheat production variability

A new study reveals that heat stress concurrent with drought or water excess can explain about 40% of the changes in wheat yields from one year to another. Water excess affects wheat production more than drought in several countries, contributing to reduced yields due to increased pests and diseases.

Research for an oil (palm) change

A new technique developed by James Cook University scientists helps oil palm growers predict crop yield, nitrous oxide emissions and nitrogen leaching. The research provides valuable information for on-farm decision making, enabling growers to make decisions that balance productivity and environmental sustainability.

Drivers of insecticide use

A new study by UC Santa Barbara scientists has found that landscape characteristics, such as crop diversity and field size, affect insecticide use. Crop diversity was shown to reduce insecticide use by 8kg per hectare in table grapes, while larger fields use more insecticide.

Cover, crimp, cultivate?

Researchers explored three organic methods to suppress weeds: using cover crops instead of disks, turning them under, or flatening with a crimper. While some found cover crops to be effective in reducing weeds, the team also noted that unexpected weather conditions and soil fertility issues impacted results.

Domesticated rice goes rogue

A recent study has discovered the ancestry of Asian rice and its weedy cousins, revealing that rice has a natural tendency towards becoming weeds. The research found that both strains evolved from different crop varieties, with relatively few changes needed to turn the crop plant into a weed.
