Can simple measures of labile soil organic matter predict corn performance?
Organic matter is important for soil health and crop productivity. While an indicator of soil quality, a lot of organic matter is in extremely stable forms, and the nutrients in such forms are difficult for plants to use. The active, labile fraction, however, is a modest but important part of the organic matter. “The labile fraction is small – usually less than 20 or even 10 percent, ...

Nitrogen recommendations based on crop reflectance
Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

Fertiliser can offset heat for African farmers
[NAIROBI] African smallholders in dry areas can overcome climate change and even double crop yields if they invest in fertiliser use and harvest rainwater, researchers have found. Farmers in arid and semi-arid areas usually protect themselves from climate-related losses by investing as little as possible in farm inputs such as fertilisers. But in doing so they fail to grab opportunities for ...

International crop breeding programme needed for African farming
Climate change poses a large threat to African agriculture, but there is little research on how to respond. A recent study indicates that traditional adaptation methods are not enough and international collaboration is needed in 'planned adaptation' by collecting and conserving certain crops for the future. A large proportion of the African population - mainly the poor - depend on agriculture ...

Straw covering on soil can increase crop yields and improve the efficiency of water use
Straw from previous harvests can be used to help increase crop yields and improve the efficiency of water use in arid regions, finds a new study from China. By testing different techniques to improve water efficiency, the researchers found that the most effective method involved using straw to cover the soil when growing maize and wheat together in the same growing season. In north-western ...

Crop yields stall in China, India
China and India, the world's two most populous countries, are beset by stagnation in the production of staples like rice, wheat, soybean and maize (corn), says a new study on crop yield growth. Based on statistics from around the world during the 1951– 2008 period, the study 'Recent patterns of crop yield growth and stagnation', says that for some crops in China and India the spatial ...

Drones effective tools for fruit farmers
People have used the phrase “drone on and on” for a long time. Webster’s dictionary defines this figure of speech as “to speak for a long time in a dull voice without saying anything interesting.” Yet, in agriculture, drones aren’t dull, at all! Farmers use drones to be more efficient. Drones help farmers improve yields and stay ahead of problems before they ...
