  • Cultivating energy crop production

    A NEW Farm Bill is moving through the Congressional legislative process. Along the way, commercial agriculture is debating the energy impacts of future corn and soybean production. The growth of corn-based ethanol and soybean-based biodiesel has created competition for the feed inputs into animal agriculture, namely corn and soybeans. While most of agriculture discusses energy production from ...

  • Crops flourish with Scalewatcher

    Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit.  Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated ...

  • Nutrient Management: Recycling Residuals Into Animal Feed

     Composting Reduces Fuel and Labor Costs on Family Farms Jeff and Pam Riesgraf — who manage a certified organic dairy and crop operation near Jordan, Minnesota — began composting manure from their dairy herd in 1993. They had two major objectives. First, they wanted to reduce weed seeds naturally present in manure. At the same time, they understood the need to protect water quality by ...

  • Zonejection: Conservation tillage manure nutrient delivery system

    Manure application in minimum till (MT) systems is a challenge worthy of attention because residue cover is a keystone for environmental protection. To develop a system combining zone tillage and manure application into one operation (zonejection), two experiments were conducted. In Exp. 1, liquid swine manure (LSM) was applied in fall or spring for two site years (A, B). In Exp. 2, LSM was ...

  • 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. ...

  • Crop sensors outdo farmers at choosing nitrogen rates

    Choosing how much nitrogen (N) to put on corn fields isn’t something farmers take lightly. Many factors go into the decision, including past experiences, the timing of application, yield goals, and results from soil tests. Nevertheless, crop sensors can select N rates for corn that outperform those chosen by farmers, according to more than 50 on-farm demonstration projects conducted in ...

  • Can nutrient trading shrink the Gulf of Mexico`s dead zone?

    The Gulf of Mexico has the largest dead zone in the United States and the second-largest in the world. Dead zones form when excessive amounts of nitrogen and phosphorous wash into waterways and spur algal blooms, depleting the water of oxygen and killing fish, shrimp, and other marine life. The Gulf of Mexico dead zone can ...

  • A review of the phosphorus content of dry cereal and legume crops of the world

    When food scarcity increases, instability in society increases. The majority of food consumed is from cereals and legumes. Phosphorus is essential for crop plant growth and soils are depleted as this element is removed from crop lands with harvested grains/seeds. To sustain yields, inputs of nutrients are required to balance losses. On global and continental/regional bases, we assembled nine ...

  • Rotary batch blender mixes biological products that boost farm crops

    Agriculture has never been more challenging and fertility efficiency tools, such as inoculants, more important. Modern farmers rely on technology and production practices to significantly increase the yield of their food crops. Biological products like inoculants are a vital part of that strategy. Novozymes Biologicals is an industry leader in developing and manufacturing inoculants, which are a ...

  • An overview of preharvest factors influencing postharvest quality of horticultural products

    Postharvest product quality develops during growing of the product and is maintained, not improved by postharvest technologies. Available genetic material allows discrimination of external and internal quality attributes that must satisfy consumer requirements and indulgences. Farmers face challenges in utilising technologies for producing high quality crops; meaningful manipulation of light, ...

  • Reuse: Agriculture

    Agronomic and water quality considerations Water use for agricultural irrigation is the largest component of water use in most countries and is more than 70% of human water use in drier countries. Use of recycled water for irrigation requires consideration of soil types, groundwater levels, soil and water chemistry, nutrient loads, limits on chemicals, the salt tolerance of ...

  • Five Ways to Manage the Soil for Planting

    The soil, as the primary resource for food production and the most important tool for every farmer, is crucial for farming. Successful farming begins with the quality soil, which provides water and essential nutrients to the crops. Rich and healthy soil, combined with the appropriate amount of water and sunlight can significantly contribute to global food production. Proper soil management ...

  • Family farms can be competitive by focusing on conservation and stewardship

    While the U.S. Department of Agriculture (USDA) reports a 40 percent decline in U.S. cropland soil erosion rates from 1982 to 2007, recent trends appear to challenge this progress. Record prices for corn and soybeans have diverted acres out of conservation programs and encouraged intensive production on a wide scale. Tree lines are cleared and wet areas drained, turning 120-acre farms into ...

  • High-Yielding corn response to applied Phosphorus, Potassium, and Sulfur in Nebraska

    Nutrient management recommendations may change as yield levels and efficiency of crop production increase. Recommendations for P, K, and S were evaluated using results from 34 irrigated corn (Zea mays L.) trials conducted in diverse situations across Nebraska. The mean yield was 14.7 Mg ha–1 with adequate fertilizer applied. The median harvest index values were 0.52, 0.89, 0.15, and 0.56 for ...

  • The Best Practices for Using Plant Residues

    Plant residue are crop materials such as stems, leaves, and roots, that are left on the field after the harvest. In the past, farmers considered crop residue to be trash, that was usually destroyed by fire. However, today this practice is not recommended and highly is not used by farmers. There are two different ways to manage crop residues. The first method is tillage prior planting when plant ...

  • Stud case study

    A major vegetable grower in Lantokia, Fiji, using soilless culture systems began to trial Amnite A-100. His crops consisted principally of lettuce, tomatoes, capsicums, cucumbers, zucchinis and melons. Before the trials they had been plagued with root diseases, mosaic virus and insect attack, control of which required constant use of pesticides and ultraviolet lighting. The first trials commenced ...

  • Peak phosphorus - conserving the world`s most essential resource

    Abstract Phosphorus (P) is one of the three major plant nutrients but it is the scarcest on the planet; at the current rate of exploitation, today's resources will be exhausted in about 70 years; 80% of the extracted P is used as fertiliser. Additional reserves might last another 200 years; when they are exhausted, crop yields will decline rapidly. All living cells require P; it cannot be ...

  • Fertilizer NPK from human urine and olive oil mill wastewaters

    The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two ...

  • Reuse of treated wastewater using sequencing batch bioreactor for the improvement of wheat growth

    Reclaimed wastewater reuse for irrigation to crop plants is evaluated in a laboratory-scale experiment to assess growth and water saving potential from natural resources. A prototype laboratory-scale treatment plant was established for this purpose with suspended and attached growth configurations. Chakwal wheat variety was selected to examine growth parameters. The removal of chemical oxygen ...
