  • Disasters Show Importance of Ag Risk Management Tools

    Mother Nature is an unreliable farming partner. Sometimes the weather helps, but too often it also hurts us. And there’s been a lot of hurt lately. Hurricanes have flooded east Texas. They have destroyed about half of the remaining citrus crop, flooded pasture and blown away much of the sugarcane in Florida. They have leveled pecan trees and pine trees in southern Georgia. Meanwhile, ...

  • Corn belt assessment of cover crop management and preferences

    Surveying end-users about their use of technologies and preferences provides information for researchers and educators to develop relevant research and educational programs. A mail survey was sent to Corn Belt farmers during 2006 to quantify cover crop management and preferences. Results indicated that the dominant cereal cover crops in Indiana and Illinois are winter wheat (Triticum aestivum L.) ...

  • Organic and mineral input management to enhance crop productivity in Central Kenya

    Organic resources (ORs) are important nutrient inputs in tropical agriculture. Combined with mineral fertilizers, they form the backbone of integrated soil fertility management. This study was conducted to determine the medium- to long-term influence of OR quality and quantity on maize productivity and to evaluate the occurrence of additive benefits in terms of extra grain yield produced by the ...

  • Italian ryegrass management effects on nitrogen supply to a subsequent potato crop

    There is increasing use of Italian ryegrass (Lolium multiflorum Lam.) as a green manure in potato (Solanum tuberosum L.) rotations; however, effects of its management on soil N supply to the subsequent potato crop are unknown. Fertilizer N management and plow-down date for a preceding Italian ryegrass crop, ‘Lemtal’, on soil N supply to a subsequent potato crop, ‘Russet Burbank’, was determined ...

  • Agricultural Management Practices to Sustain Crop Yields and Improve Soil and Environmental Qualities

    Increasing crop production to feed the growing population was a major challenge to the agricultural community in the past few decades. As a result, management practices consisting of intensive tillage and high rate of fertilization were used to increase crop production. While these practices increased crop production by severalfold compared with less intensive tillage and no fertilization, little ...


  • In-situ soil moisture conservation: utilisation and management of rainwater for crop production

    The salient results of in-situ soil water conservation technologies that have been found suitable for increasing soil moisture in the arid and semiarid lands of eastern Kenya are reviewed. The results showed that Zai pits, tumbukiza and deep tillage when used together with soil fertility improvement can increase crop yields by 4–10 times in comparison to conventionally ...

  • Summer cover crop and management system affect lettuce and cantaloupe production system

    Cover crops are widely used in both conventional and organic systems to protect and improve the soil. This study evaluated the effect of summer cover crop and management system on the production of fall romaine lettuce (Lactuca sativa L.) and spring cantaloupe (Cucumis melo L.) from 1999 to 2003. Cover crop treatments included cowpea [Vigna unguiculata (L.) Walp.] incorporated (CPI), cowpea used ...

  • Can water use efficiency be modeled well enough to impact crop management?

    Crop water use efficiency (WUE, yield per unit of water use) is key for agricultural production with limited water resources. Policymakers and water resource managers working at all scales need to address the multitudinous scenarios in which cropping systems and amounts, timing and methods of irrigation, and fertilizer applications may be changed to improve WUE while meeting yield and harvest ...

  • Emissions from Crops - POST Note

    Agriculture contributes 9% of the UK’s greenhouse-gas (GHG) emissions burden and 10-12% globally. Although there is a long-term declining trend from UK agriculture, the sector may account for a larger share of overall emissions in the future as other sectors reduce emissions. This POSTnote focuses on reducing GHG emissions from growing and storing arable and horticultural crops. ...

  • Manure Compost A New Cash Crop

    A growing number of livestock producers are discovering manure compost as a new cash crop. When Mark Meyer refers to the “magic” at New Day Farms, he isn’t referring  to  the  liquid  egg  products  generated  by more than 2.5 million laying hens. Rather, Meyer, the environmental manager  at the Ohio facility, is talking about the ...

  • Modeling olive crop yield in andalusia, spain

    Andalusia (southern Spain) is the largest olive (Olea europaea L.) oil producing region in the world. This study sought to identify the main factors influencing olive fruit production in this region, by modeling pollen release as an index of flowering intensity, field floral phenology data, and meteorological data over the fruiting season in three main olive-producing provinces of Andalusia: ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • Asia–Pacific Analysis: Plan for growth in biotech crops

    South-East Asian nations should follow the Philippines down the path to biotech crops for food security, argues Crispin Maslog. Since biotechnology-derived crops were introduced in 1996, they have been adopted at an unprecedented rate, according to the 2011 annual report of the International Service for the Acquisition of Agri-biotech Applications (ISAAA) released earlier this year. ...

  • High yielding organic crop management decreases plant-available but not recalcitrant soil phosphorus

    Phosphorus is a nonrenewable resource, raising concerns that agricultural practices may deplete reserves. Organic farming with low P inputs can result in deficient levels of plant-available phosphorus (available-P). The purpose of this study was to determine if common organically managed rotations are depleting P reserves or if large reserves still exist in unavailable forms. The research was ...

  • Simulated effects of Nitrogen management and soil microbes on soil Ntrogen balance and crop production

    Searching for environmentally friendly N management practices in the midwestern United States is an ongoing task in the agricultural community. Many practices have shown promise in reducing N in tile drainage that may contribute to hypoxia in the Gulf of Mexico. In this study, an agricultural system in central Iowa, managed using a corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotation from ...

  • Advancements in chemistry are providing growers with flexibility when managing slug pressures in potato crops.

    Flexibility in slug control The mild and wet weather and lack of ground frosts seen this winter, means that being vigilant to slug activity will be key as we move into the potato planting season. Andrew Sprunt, Agrii’s Northern region potato technical agronomist, explains what growers can expect from the season ahead, and how to manage the potential impact at farm level, ...

  • Performance of an optimized nutrient management system for double-cropped wheat-maize rotations in North-Central China

    Overapplication of N and P and insufficient supply of K are considered primary reasons for restriction of yield improvement in the North China Plain. Optimized nutrient management practices based on soil testing and yield targets have been developed. Other large scale field experiments have indicated that additional improvement for yield and nutrient use benefits is needed. The objective of this ...
