  • Discerning shifting irrigation practices from passive microwave radiometry over Punjab and Haryana

    Overexploitation of groundwater (GW) in the recent past is a well-known fact for the Punjab and Haryana region of India, as reported by several studies using satellite-based gravity anomaly from the Gravity Recovery and Climate Experiment mission and also by using observed data. This decline in GW has enforced the Punjab Preservation of Sub-Soil Water Act 2009, and resulted in change in rice ...

  • Case study - Miscanthus mother plantation - KSG Agro Group, Ukraine

    Another project successfully completed in May 2013 was the establishment of the Miscanthus mother plantation in Ukraine. The task was carried out under the contract with Ukrainian company KSG Agro S.A. listed at Warsaw Stock Exchange. The investment was aimed on establishing several dozen hectares Miscanthus mother plantation on the land that belongs to KSG Agro Group. In the context of the ...

  • Seeds of change in sub-Saharan Africa

    In the late 1900s, as per-acre grain yields moved to 3 metric tons per hectare in South and Southeast Asia and Latin America, 5 metric tons per hectare in China, and 10 metric tons per hectare in North America, Europe and Japan, there’s one place where production stagnated big time: sub-Saharan Africa, where loss of soil fertility on small farms trapped grain production at an unsustainable ...

  • 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 ...

  • The transport of three emerging pollutants through an agricultural soil irrigated with untreated wastewater

    The aim of this work was to determine the mobility of naproxen, carbamazepine, and triclosan through a wastewater-irrigated agricultural soil. Transport experiments were carried out using undisturbed soil columns taken at 10 and 40 cm depths. The mobilization of the pollutants was evaluated using two hydrological regimes transient flow for superficial columns and steady-state conditions for the ...

  • 3 Unexpected ways to improve food security in Sub-Saharan Africa

    The United Nations’ new population growth projections show that the world is set to reach nearly 9.6 billion by 2050. This growth holds serious implications for global food security. Absent other effective measures to control dietary shifts and ...

  • Soil water reserve estimation and vegetation relationships in a Mediterranean sub-humid forested catchment

    A simple water balance model was used to calculate soil water reserve in a Mediterranean forested catchment. The relationship between soil water reserve and leaf water potential and stem water content was analysed. The usefulness of these variables as plant water status indicators was tested. The analyses were developed with a seven-year-long database (2001–2007) in the case of soil water content ...

  • Engaging High School students in soil science inquiry

    In April 2007, teacher Irka Elsevier and then-graduate student Biance Moebius-Clune began their second inquiry unit designed to enable high school students to better understand soil science concepts through their own research and experiments. Moebius-Clune was an NSF fellow in the Cornell Science Inquiry Partnerships (CSIP) program, which allowed the pair to develop inquiry curriculum to guide ...

  • Let the kids go wild outdoors

    A number of international studies have shown that children in developed nations spend an average of 55 hours a week indoors using electronics. Even though this means that the youth in these countries are techno-savvy, it often results in them spending less and less time outdoors. How do we change this, and get our kids to experience the wonders of nature, develop creativity and learn to ...

  • Modelling urban canopy and terrain for transport diffusion simulations at sub-mesoscales

    Studies of the transport and dispersion of atmospheric pollutants at the scale of a part or the whole of an urban agglomeration require numerical simulations over domains between a few kilometres and a few tens of kilometers (sub-meso scale to meso-y scale). Current computer capabilities do not allow for a grid resolution sufficiently fine to explicitly simulate the flows at the scale of urban ...

  • Assessing short-term responses of prokaryotic communities in bulk and rhizosphere soils to tall fescue endophyte infection

    Abstract In contrast to endophyte-free (E−) tall fescue, endophyte-infected (E+) tall fescue pastures appear to enhance soil carbon sequestration. A hypothetical mechanism that may account for the enhanced carbon sequestration is that the E+ tall fescue affects the soil microbial community or components of it that are involved in organic carbon turnover. A 60-week mesocosm study with a ...

  • The Relationship Between the Soil-Water Characteristic Curve and the Unsaturated Shear Strength of a Compacted Glacial Till

    Soils compacted at various “initial” water contents and to various densities should be considered as “different” soils from a soil mechanics behavioral standpoint even though their mineralogy, plasticity, and texture are the same. The engineering behavioral change from one specimen to another will vary due to differences in soil structure or aggregation. The shear strength of an unsaturated soil ...
