  • Decomposition of the organic matter of natural and concentrated vinasse in sandy and clayey soils

    Vinasse has been used as fertilizer by sugarcane growers, due to its potential to completely replace mineral fertilizers. However, if the application is not adequate, this practice may cause environmental contamination. This study used a respirometry test to evaluate the organic matter (OM) decomposition present in natural vinasse and concentrated vinasse (CV), with or without urea addition. ...

  • How the Earthworm Improves the Soil

    Nature has ways of converting vegetable and mineral raw materials into high-quality products. The inconspicuous earthworm provides striking example — it is a minirefinery in the soil. The dew worm or common earthworm, which is native to Europe, is just one of more than 3000 earthworm species in the world. About 30 centimeters long, the powerful earthworm digs ...

  • Estimation of the degree of soil P saturation from Brazilian Mehlich-1 P data and field investigations on P losses from agricultural sites in Minas Gerais

    The degree of phosphorus saturation (DPS) of agricultural soils is studied worldwide for risk assessment of phosphorus (P) losses. In previous studies, DPS could be reliably estimated from water-soluble P (WSP) for European and Brazilian soils. In the present study, we correlated measured WSP and Mehlich-1 P (M1P) from soils of Minas Gerais (MG) and Pernambuco (PE) (R2 = 0.94, ...

  • Estimation of Ascaris lumbricoides egg inactivation by free ammonia treatment of ash-amended UDDT vault products using stored urine in Uganda

    Urine-diverting dry toilets (UDDTs) are designed to recover nutrients and organic matter from human excreta for use as agricultural amendments, and have been promoted in many developing countries, including Uganda. Wider UDDT implementation could help address problems in areas where water scarcity limits sanitation coverage and/or declining soil fertility jeopardizes growing populations’ ...

  • 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 ...

  • Influence of soil properties and soil leaching on the toxicity of ionic silver to plants

    Silver (Ag) has been shown to exhibit antimicrobial properties and as a result it is being increasingly used in a wide range of consumer products. Due to these uses, there is an increased likelihood that Ag may enter the environment, predominately via land application of biosolids or irrigation with treated wastewater effluent. The aim of this study was to investigate the toxicity of Ag to two ...

If ...

  • Rice production with minimal irrigation and no nitrogen fertilizer by intensive use of treated municipal wastewater

    We designed a new cultivation system of rice with circulated irrigation to remove nitrogen from treated municipal wastewater effectively and assessed the possibility of nitrogen removal in the new system without any adverse effects on rice production through bench-scale experiments through two seasons. Overgrowth of the rice plant, which can lead to lodging and tasteless rice, was found in the ...

  • 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 ...

  • Promotion of pyrene removal from soils by Bidens maximowicziana

    A pot experiment was conducted to investigate the potential of removal of pyrene from spiked soils planted with Bidens maximowicziana . The removal of pyrene from the spiked soils planted with B. maximowicziana was obviously higher than that from the unplanted soils. After 50 d, the removal ratio of pyrene in the planted soils was 79%, which was 28% higher than that of the ...

  • Toxicity of pesticides associated with potato production, including soil fumigants, to snapping turtle eggs (Chelydra Serpentina)

    Turtles frequently oviposit in soils associated with agriculture and, thus, may be exposed to pesticides or fertilizers. The toxicity of a pesticide regime that is used for potato production in Ontario on the survivorship of snapping turtle (Chelydra serpentina) eggs was evaluated. The following treatments were applied to clean soil: 1) a mixture of the pesticides chlorothalonil, ...

  • Oil Palm on Peat: A path to (inevitable) disaster

    Oil palm cultivation on peatlands is seen as an attractive option for many plantation developers in Southeast Asia. Not only is the land extensively available, the soils – despite the poor soil fertility – are somehow “working” for oil palm cultivation. Peatlands can therefore be perceived as lucrative and attractive for expansion of oil palm plantations. ...
