  • State Fertilizer Officials Focus on Compost

    For two years, the U.S. Composting Council’s (USCC) marketing committee has been meeting with the American Association of Plant Food Control Officials (AAPFCO) to discuss how the two organizations could work together to create a uniform compost bill to be given to each state legislature to consider adopting into law. AAPFCO is an organization of fertilizer control officials from each state in the ...

  • Application of rural slaughterhouse waste as an organic fertilizer for pot cultivation of solanaceous vegetables in India

    Background:The lack of electricity and water supply in rural abattoirs in developing nations prevents the adoption of waste-processing technologies practiced in economically advanced countries. This research attempts to recycle waste blood and rumen digesta generated in rural slaughterhouses as organic fertilizer, thus promoting sustainable agriculture. Results:The values of 5-day biochemical ...

  • Animal Manure or Sludge Organic Fertilizer Production

    Introduction of Animal Manure or Sludge Organic Fertilizer Production Line Organic fertilizer production line is designed for producing organic fertilizer from animal manure or sludge, without any chemical ingredients. As chickens, pigs have a poor digestion, can only consume 25% of the nutrients, so other 75% of feed nutrients with feces discharge can be produced to the dry ...

  • Poul-AR Valorization of poultry manure - Fertilizer and energy from poultry manure

    Application In contrast with generic manure types, poultry manure is very rich in nutrients as nitrogen (N) & phosphorus (P), but also in organic material. Both the form and the N/P ratio in which the nutrients are present make the manure less suitable for direct application as natural fertilizer. It leads to the release of large and undesired amounts of volatile ammonia into the ...

  • Will variable-rate nitrogen fertilization using corn canopy reflectance sensing deliver environmental benefits?

    Within-field variability of corn (Zea mays L.) N need calls for development of precision fertilizer application strategies. One approach many are investigating is in-season canopy reflectance sensing. Justification for this strategy partly rests with the premise it will improve N use and reduce N loss from fields. The objective of this study was to determine the potential environmental benefits ...

  • Nitrogen recovery from source-separated human urine using clinoptilolite and preliminary results of its use as fertilizer

    The use of source separated human urine as fertilizer is one of the major suggestions of the new sanitation concept ECOSAN. Urine is rich in nitrogen, phosphorus and potassium which act as plant nutrients, however its salinity is high for agricultural and landscape purposes. Moreover, characteristics change significantly throughout storage where salinity increases to higher values as the ...

  • GWT Case Study - Agriculture Processing Sector

    Application Case Studies - Agriculture Plant Nursery Challenge A plant nursery company had water quality issues from the well water source that there were using for irrigation purposes in their plant growing operations. These water quality issues including total dissolved salts (TDS) around 2500 mg/l, as well as turbidity, mineral hardness ...

  • 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 ...

  • Cover-all building ideal for composting process

    Hy-Line International is a multi-million dollar company whose primary purpose is the sole production, multiplication and distribution of leghorn genetics.  At its Iowa facility in Dallas Center, Hy-Line chose to handle its hatchery by-product in a cost effective manner by combining it with field by-products, such as corn stocks and chicken manure, to create a compost product for ...


  • Tilapia Fingerlings Feed formulation and Pellet Processing

    Tilapia fingerlings feed formulation and feed processing technology are significant for tilapia farming. Here we offer  the detailed information to help feed pellet production. 1. Feed Formula of Tilapia Fingerlings 2. Basic demands for feed pellet processing: Receiving Different Types of Raw Materials; Storing Raw Materials; Cleaning Raw ...

  • Land application of sugar beet by-products: effects on Nitrogen mineralization and crop yields

    Land application of food processing wastes has become an acceptable practice because of the nutrient value of the wastes and potential cost savings in their disposal. Spoiled beets and pulp are among the main by-products generated by the sugar beet (Beta vulgaris L.) processing industry. Farmers commonly land apply these by-products at rates >224 Mg ha–1 on a fresh weight basis. However, ...

  • Land application of sugar beet by-products: Effects on runoff and percolating water quality

    Water quality concerns, including greater potential for nutrient transport to surface waters resulting in eutrophication and nutrient leaching to ground water, exist when agricultural or food processing industry wastes and by-products are land applied. Plot- and field-scale studies were conducted to evaluate the effects of sugar beet by-products on NO3–N and P losses and biochemical oxygen demand ...

  • Improving the fermentation characteristics of corn through agronomic and processing practices

    This study determined the influence of corn (Zea mays L.) hybrids, N availability, grain harvest moisture, and drying temperatures on dry-mill ethanol production. Six hybrids, ranging from 92 to 108 d in relative maturity (RM), were planted at two locations over 2 yr. One of four N fertilizer treatments were applied. Grain was hand-harvested at grain moistures of 20 and 25%. Grain was dried to ...

  • Agrior Project, Chaudière-Appalaches, Quebec, Canada

    Compost Drying Application Agrior makes high value organic fertilizers by composting a mixture of animal manure and organic municipal and industrial wastewater treatment sludge. A DRY-REX low-temperature drying system was designed and installed at Agrior’s facility to dry the mixture into high-quality compost. The low-temperature process results in the drying of the manure with minimal ...

  • Effects of different composts on soil nitrogen balance and dynamics in a biennial crop succession

    Italy is faced with increasing pressures to reduce the amount of refuse disposed of in landfills. Compost represents a contribution to solve this problem. To give information for the correct management of composts as nitrogen fertiliser, it is necessary to assess their nitrogen release rhythm compared with the crop needs. This semi-field trial investigated the performance of three different ...

  • Phosphorus And Compost Use Dynamics

    Organic forms of phosphorus, such as biosolids and compost products, contain low to very low levels of water extractable phosphorus, but increasingly are regulated like inorganic P sources. Phosphorus is one of the 16 essential plant nutrients, and is considered one of the three major plant nutrients (along with nitrogen and potassium). Phosphorus is not only important in root development, but ...

  • 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 ...

  • Use of Fat, Oil and Grease Waste as an Agricultural Soil Conditioner

    Wastewater from the food processing and food service industries can contain large quantities of fat, oil and grease (FOG). Most North American jurisdictions have bylaws limiting the concentration of oil and grease in sewer discharges. As municipal source control efforts become more aggressive, quantities of FOG waste requiring proper treatment/disposal will increase. At the same time access to ...
