Within WRAP’s Organics Programme, the overall aim is to increase the manufacture and purchase of quality compost through capital funding, marketing, training, quality assurance as well as research and development. It has been ...

  • Water institutional reforms in South Africa

    ABSTRACT A comprehensive program of water institutional reforms has been implemented in South Africa since 1994. These reforms followed some major reform on the political and economic fronts. The institutional changes that occurred in the water sector covered the policy legal, and organizational dimensions of water allocation and management and affected all water sub-sectors including ...

  • India's groundwater irrigation boom: can it be sustained?

    Development of groundwater irrigation (GWI) has been very impressive in India, especially after the introduction of the green revolution. The area under GWI accounts for 62% of the net irrigated area today. Though GWI provides added benefits to farmers, compared to other sources of irrigation, the continuous exploitation of groundwater of late has resulted in a drastic drop in the water table, ...

  • No-till sequential cropping of summer and fall annual forage species compared with grassland

    Summer (SAS) and fall annual species (FAS) can supplement animal forage requirements during times of slow growth of cool-season perennials. A 2-yr experiment was conducted in a perennial grassland (G) at the Reedsville Experimental Farm of West Virginia University to determine herbage accumulation (HA) and quality of two summer and two fall crops (in factorial combination) grown on the same land. ...

  • Nutrient status in Alpine soils of the Colorado front range using the Nitrogen/Phosphorus ratio index

    The suitability of the foliar N/P ratio was evaluated as a predictor of nutrient limitation in an alpine ecosystem of the Colorado Front Range. We hypothesized that foliar N/P ratios are directly correlated with the alpine soil nutrient status. We used a long-term fertilization experiment conducted in three alpine plant communities, where 48 plots were established consisting of four replicates of ...

  • 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 ...

  • Productivity, oil content, and composition of two spearmint species in Mississippi

    ‘Scotch’ (Mentha x gracilis Sole) and ‘Native’ (Mentha spicata L.) spearmints are grown in the northern United States, but have not been evaluated in the Southeast. Two-year field studies were conducted in Mississippi at two locations (Verona and Stoneville) to evaluate the effects of N application rate and cut (harvest time) on yields, essential oil contents, compositions, and the yield of ...

  • QTL underlying self-fertility in tetraploid alfalfa

    A potential strategy to decrease the levels of self-seed production during the seed increase stages of alfalfa (Medicago sativa L.) synthetic cultivar development is selection for decreased self-fertility. The underlying genetics of this trait have not been elucidated and, therefore, a study was designed to identify genetic determinants of alfalfa self-fertility. An F1 mapping population ...

  • And the Award for Most Creative Use of a Porometer Goes to…

    Decagon employees have found some novel uses for the porometer over the years.  Since the sensor head measures stomatal conductance simply by determining vapor flux, they’ve clamped it on everything from fingers to house wrap to raincoats.  But Jan Narciso and her colleagues at the USDA in southern Florida have now “clamped” it on something even bigger…a ...

  • Water for agriculture and the environment: the ultimate trade-off

    Global population is projected to increase over year 2000 levels by 30% in 2025 and by 50% in 2050. Producing sufficient food to feed a more populous Earth will be a challenge requiring additional developed water supplies. Existing supplies are unevenly distributed around the planet. Some developing countries lack sufficient water to grow the food necessary to feed the growing population. With ...

  • Turkey: Transfer of irrigation management to water users associations

    Up to the early 1980s, operations and maintenance for irrigation systems was highly centralised, but this was imposing an increasing institutional and financial burden on the government. Contributing factors were: very low ...

  • 3 Great Ways to Use Your Farm Drone During the Off-Season

    You may have finished up your 2016 harvest, or perhaps getting a jump start on planning for the 2017 growing season, but think twice before putting away your farm drone for the winter. Just because you’re not actively working in the field does not mean your quad-copter shouldn’t play an active role in your off-season operations. Here are some great ways you can use your farm ...

  • Discovering Reservoir Operating Rules by a Rough Set Approach

    An integrated Rough Set approach is proposed and implemented to discover the historical operating rules of a Sicilian irrigation purpose reservoir. Operating rules are derived by expressing monthly releases from the reservoir as functions of stored volume, inflowand release during a 35-years period. This is accomplished through the Rough Set approach as implemented in the Rose package and the use ...

  • Multifunctional agriculture, non-trade concerns and the design of policy instruments: applications to the WTO agricultural negotiations

    This article focuses on how to achieve non-trade concerns (NTC) and multifunctional goals that countries may have with minimal trade-distortion. The term 'multifunctional agriculture' focuses on the issue that agriculture, in addition to the production of food and fibre, also may provide national food security, environmental benefits and viable rural areas. The article claims that ...

  • North American agriculture: its contribution to the green house effect

    This paper assesses the effect of agricultural systems and changing input use in North American agriculture on CO2 emissions. These emissions are linked to the greenhouse effect. In the early part of the 20th century, there was a significant increase in CO2 emissions as a large amount of land was diverted from its grassland state into cultivated cropland. CO2 emissions from North American ...

  • Survey of lanthanoids in plants from a tropical region

    Several anthropogenic sources may provide lanthanoids (La, Ce, Nd, Sm, Eu, Tb and Yb) to the agricultural and forestry landscapes. Because little information is available on the distribution of these chemical elements in Brazilian tropical ecosystems, this work focuses on the survey in leaves of diverse plant species (native trees, epiphytes and crops) from different ecosystems. Soil under crown ...

  • Stochastic order-based optimal design of a surface reservoir–irrigation district system

    This paper explores the effects of streamflow uncertainty and the type of stochastic order, which is used for comparing stochastic variables, on optimal design of a reservoir multi-crop irrigation district system. Four nonlinear mathematical programs with an economic objective function including deterministic, stochastic-EXP with expected value order, stochastic-SD with stochastic dominance (SD) ...
