  • 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 ...

  • Knowledge of Farm Practices – The Key for Successful Farming

    Agriculture plays an important part in the world economy. One-third of the economically active population obtains its livelihood from agriculture. In Asia and Africa, millions of small-scale farmers, fishermen, and indigenous people produce most of the food consumed worldwide, in most cases on very small plots of land. Agriculture is increasingly called upon to address a wide range of critical ...

  • Analysis of Organic Fertilizer Market

    Organic fertilizer is processed by fermenting the animal and plant residues, it not only contains major elements that plant required such as nitrogen, phosphorus and potassium, also contains microelements such as molybdenum, zinc, iron, copper and other trace elements which is ...


  • Can chemical treatments to displace radioisotopes influence soil fertility? A laboratory trial

    Soils contaminated with radionuclide pose a long–term radiation hazard to human health through exposure via the food chain and other pathways. Remediation of contaminated soils has become increasingly important. The feasibility to move radionuclides from superficial soil layers to a deeper level using an acid leaching solution was already illustrated previously. As this chemical treatment may ...

  • Local fertilizer manufacturing: A new look at agro-business

    The American farmer works in a tough business. Aside from the demanding physical and mechanical processes to raise fertile crops from tiny seeds, the farmer must also battle against supply for adequate water, the right seeds, pest and weed control products, and various fertilizers. All these elements have added stress and cost to bring a crop to market, making it less profitable than ever to ...

  • Nitrogen Fertilizer Industry: March towards getting Greener

    AbstractA major concern to the growth and development of fertilizer manufacturing industries all over the world is on the environmental front. Serious efforts are underway to make fertiliser technologies most environment friendly and sustainable with the help of research and development initiatives in technology as well as management of facilities. Technology plays a key role in improving ...

  • Soil fertilization with wastewater biosolids – monitoring changes in the ‘soil–fertilizer–plant’ system and phosphorus recovery options

    The aim of this study is to establish changes that may occur after a prolonged application of wastewater sludge treated to biosolids, in the ‘soil–fertilizer–plant’ system. Thirteen experimental plots with different soil types planted with experimental crops were investigated in order to evaluate the suitability of these biosolids as soil conditioners and fertilizers. The biosolids were ...

  • HRC Pilot Test Reduces Fertilizer Contamination at an Agricultural Facility

    Site Summary Ammonia nitrate is the most common chemical used in fertilizers, providing nitrogen to plants for growth. Dichloropropane (DCP) has also become popular in agriculture as the most common pesticide sprayed on fruit and nut crops to control nematodes. When released into groundwater, nitrate and DCP can be hazardous to human health. A distributing facility in Northern California housed ...

  • 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 ...

  • Broiler litter fertilization and cropping system impacts on soil properties

    Understanding the effects of management practices on soil properties is necessary because soil properties are directly related to the capacity of soil to function. Soil physical, chemical and biological properties were determined after 3 yr in three cropping sequences [continuous cotton (Gossypium hirsutum L.) (CCC), cotton-corn (Zea mays L.)-cotton (CMC), and corn-cotton-cotton (MCC) each at ...

  • 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), ...

  • Value of composted organic wastes as an alternative to synthetic fertilizers for soil quality improvement and increased yield

    One of the major problems with agricultural soils in the tropical region of the western Pacific islands is their low organic matter content, which results from rapid decomposition due to the hot and humid environment. Composted organic material is frequently applied on agricultural fields as an amendment to provide nutrients and also to increase the organic matter content and to improve the ...

  • Synthetic nitrogen fertilizers deplete soil nitrogen: a global dilemma for sustainable cereal production

    Received for publication December 19, 2008. Cereal production that now sustains a world population of more than 6.5 billion has tripled during the past 40 yr, concurrent with an increase from 12 to 104 Tg yr–1 of synthetic N applied largely in ammoniacal fertilizers. These fertilizers have been managed as a cost-effective form of insurance against low yields, without regard to the inherent effect ...

  • 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), ...

  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...
