  • 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 ...

  • 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 ...

  • GWT- Agro-Z nutrient soil medium enhancer

    Genesis Water Technologies case study for GWT Agro-Z specialized natural soil enhancement medium. This case study document shows the differences between vegetables grown with GWT Agro-Z zeolite soil medium and vegetables grown without this medium. Trials of seedling plants grown with the GWT Agro-Z medium have shown improvements in primary root development. Studies have resulted in better ...

  • 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. ...

  • 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 Assessment of Management Practices to Control Nutrient and Pesticide Levels in Vegetable Production Areas in the Rattaphum Catchment, Thailand

    The over-use of agrochemicals may have adverse effects on soils along with surface and groundwater. An assessment of alternative management practices to reduce the application of agrochemicals and minimise the pollution of water resources was carried out in the vegetable agroecosystem in the Rattaphum Catchment. This paper details the factors that govern the volume of agrochemicals used on high ...

  • Effect of AgraGel T-400 on tomato crops, U. of Valparaiso, Chile - Case Study

    Introduction At present, a great part of vegetable production in Chile is dedicated to industrial agronomy and one of the most important products is the tomato crop for industrial processing. Chile has a capacity of 180,000 tons of tomatoes per year, which is equivalent to 12,000 hectares of crop land. Among canned products tomato paste represents 38%. This is an important employment ...

  • Stevens Water and US Farm Bill Helps Farmers Optimize Crop Irrigation & Fertilization

    Agriculture is a major element for survival of the human race and of the economic system. 42 percent of the world’s laborers are employed in agriculture, making it by far the most common occupation. With agriculture using approximately 60 percent of available fresh water withdrawals, concerns continue to grow over farmers implementing water conservation practices. Also, increasing contamination ...

  • Effects of green manure and compost of pea plant on wheat

    Cereal based cropping systems have been established for food security in many countries where farmers use plenty of chemical fertilizers, but adoption of leguminous crop in the system is not popular. Excessive use of fertilizers is responsible for health and environmental hazards. Adoption of legume in cereal based cropping systems and improvement of organic fertilizer are needed to reduce ...

  • 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 ...

  • Sustainable Soil Health

    “A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing ...

  • Simulating yield response of quinoa to water availability with aquacrop

    The modeling of yield response to water is expected to play an increasingly important role in the optimization of crop water productivity (WP) in agriculture. During 3 yr (2004–2007), field experiments were conducted to assess the crop response to water stress of quinoa (Chenopodium quinoa Willd.) in the Bolivian Altiplano (4000 masl) under different watering conditions (from rain fed, RF, to ...

  • 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 ...

  • Effect of implementing organic farming on chemical and biochemical properties of an irrigated loam soil

    Conventional agriculture can lead to reduced soil organic matter and depletion in soil fertility. For that reason, Food and Agriculture Organization of the United Nations (FAO) recommends organic matter incorporation to soils to increase their agronomic quality. This work studies the effect of the transition to organic farming on chemical and biochemical properties of a loam soil (Xerofluvent), ...

  • Long-term study of properties of a xerofluvent of the guadalquivir river valley under organic fertilization

    The long-term effect of inorganic and organic fertilization in a vegetable crop rotation on soil chemical and biochemical properties was investigated in a trial in southern Spain. Two crops were grown in succession, potato (Solanum tuberosum L.) and a mixed-cropped strawberry–onion (Fragaria vesca L.–Allium cepa L.). Total organic carbon (TOC), Kjeldahl-N, bicarbonate-extractable P (Olsen-P), ...

  • Potassium and winter hardiness

    The role of Potassium in metabolic processes such as protein synthesis and the movement of sugars within the plant is now well understood and recognised as crucial for maximising quality and yield. But it is now known Potassium also plays a significant role in helping crops resist disease and environmental stresses during winter dormancy and ensuring optimum supplies of Potassium to see crops ...
