Autores: Adamtey, Noah; Musyoka, Martha W.; Zundel, Christine; Cobo, Juan Guillermo; Karanja, Edward; Fiaboe, Komi K.M.; Muriuki, Anne; Mucheru-Muna, Monica; Vanlauwe, Bernard; Berset, Estelle; Messmer, Monika M.; Gattinger, Andreas; Bhullar, Gurbir S.; Cadisch, Georg; Fliessbach, Andreas; Mäder, Paul; Niggli, Urs; Forster, Dionys.
In 2007 two long-term trials were established in Kenya to contribute research-based evidence to the global debate on the productivity, economic viability and sustainability of different agricultural production systems. These trials compare conventional (Conv) and organic (Org) farming systems at high and low input levels at two locations, i.e. Chuka, with Humic Nitisols, high inherent soil fertility and rainfall, and Thika, with Rhodic Nitisols with low soil fertility and rainfall. The high input systems (High) represent commercial-scale, export-oriented production that uses the recommended amounts of fertilisers, pesticides and irrigation water to generate high yields, whilst the low input systems (Low) represent local smallholder practices, using...

Improving the efficiency of rock phosphate on high pH soils: Results from participatory research in India
Provedor de dados: 21
Autores: Andres, Christian; Mandloi, Lokendra S.; Verma, Rajeev; Gomez, Sara; Nyffenegger, Mirjam R.; Locher, Michael; Patel, Dharmendra; Forster, Dionys; Bhullar, Gurbir S.; Studer, Christoph.
High soil pH levels may limit the availability of phosphorous (P) to crops. In organic farming, the use of synthetic P fertilizers is not allowed. Application of rock phosphate (RP) to crops is one of the alternatives for organic production. However, RP application shows little effect on high pH soils, because the P is not transformed into plant-available forms under alkaline soil conditions.  Aiming at the development of locally adapted solutions, we followed a Participatory Technology Development approach, making use of the local knowledge to identify current practices and associated problems by conducting focus group discussions with organic farmers. Farmers stated that they are facing challenges with a P limitation in their cotton-based production...

Variation in the plant-mediated methane transport and its importance for methane emission from intact wetland peat mesocosms
Provedor de dados: 21
Autores: Bhullar, Gurbir S.; Edwards, Peter J.; Olde Venterink, Harry.
Aims and Methods Vascular plants are known to influence the production, transport and oxidation of methane in wetland soils, but these processes are not well understood. Using plants grown in intact peat cores, we compared the influence upon methane emissions of 20 forb and graminoid species from European wetlands. We measured plant-mediated transport of methane (conduit or chimney effect) using a novel agar-sealing technique that prevented methane exchange from the bare soil to the atmosphere.   Important Findings The plant-mediated transport (chimney effect) represented between 30% and almost 100% of the total methane flux, with graminoids exhibiting greater internal transport than forbs. In general, plants with less dense root tissues and a relatively...

Methane transport and emissions from soil as affected by water table and vascular plants
Provedor de dados: 21
Autores: Bhullar, Gurbir S.; Iravani, Majid; Edwards, Peter J.; Olde Venterink, Harry.
Background: The important greenhouse gas (GHG) methane is produced naturally in anaerobic wetland soils.  By affecting the production, oxidation and transport of methane to the atmosphere, plants have a major influence upon the quantities emitted by wetlands. Different species and functional plant groups have been shown to affect these processes differently, but our knowledge about how these effects are influenced by abiotic factors such as water regime and temperature remains limited. Here we present a mesocosm experiment comparing eight plant species for their effects on internal transport and overall emissions of methane under contrasting hydrological conditions. To quantify how much methane was transported internally through plants (the chimney...

What socially motivates farmers to grow organic cotton in central India?
Provedor de dados: 21
Autores: Riar, Amritbir; Mandloi, Lokendra S.; Poswal, Randhir S.; Messmer, Monika; Bhullar, Gurbir S.
India is the largest producer of ‘organic cotton’, as it contributes about three quarters (74%) to the global organic cotton production. The Nimar valley of Madhya Pradesh in central India is important region for organic cotton production. In general, cotton yields are low and variable in the Nimar valley and often do not reach the attainable levels on several farms of the region. With a steeply increasing demand for organic fibre, it is important to safeguard and increase the production of organic cotton in a sustainable manner. The precise understanding of social and biophysical motivations of different farmers for following their respective farming practices is of high importance for sustainable future of organic cotton in central India. The study of...

Autores: Riar, Amritbir; Bhullar, Gurbir S.
Hintergrund und Bedeutung für Coop  Indien ist seit jeher Zeiten ein wichtiger Exporteur von Baumwolle. Im Jahr 2014 / 15 war Indien der größte Baumwollproduzent weltweit, mit 6,5 Millionen Tonnen produzierter Baumwollfaser. Indien ist auch der größte Produzent von "Bio-Baumwolle", mit einem Anteil von fast drei Viertel (74 %) der globalen Bio-Baumwolle Produktion. Weil die Nachfrage nach Biobaumwolle stetig wächst, ist es wichtig, die Produktion von Bio-Baumwolle auf nachhaltige Weise zu sichern – um so mehr, da sich der Anbau von genetisch modifizierter Baumwolle rasch ausbreitet. Dies ist auch für Coop äusserst zentral angesichts dessen, dass Indien der Hauptlieferant ist von Biobaumwolle für die Naturaline-Eigenmarke.  Tatsache ist, dass sich in Indien...

Provedor de dados: 21
Autores: Helfenstein, Julian; Müller, Isabel; Grüter, Roman; Bhullar, Gurbir S.; Mandloi, Lokendra; Papritz, Andreas; Siegrist, Michael; Schulin, Rainer.
Zinc (Zn) nutrition is of key relevance in India, as a large fraction of the population suffers from Zn malnutrition and many soils contain little plant available Zn. In this study we compared organic and conventional wheat cropping systems with respect to DTPA (diethylene triamine pentaacetic acid)-extractable Zn as a proxy for plant available Zn, yield, and grain Zn concentration. We analyzed soil and wheat grain samples from 30 organic and 30 conventional farms in Madhya Pradesh (central India), and conducted farmer interviews to elucidate sociological and management variables. Total and DTPA-extractable soil Zn concentrations and grain yield (3400 kg ha-1) did not differ between the two farming systems, but with 32 and 28 mg kg-1 respectively, grain Zn...

Yields and gross margins of cotton-based production systems under organic and conventional management in India
Provedor de dados: 21
Autores: Andres, Christian; Forster, Dionys; Verma, Rajeev; Zundel, Christine; Messmer, Monika; Mäder, Paul; Bhullar, Gurbir S.
The debate on the relative benefits of conventional and organic farming systems has in recent time gained significant interest. So far, global agricultural development has focused on increased productivity rather than on a holistic natural resource management for food security. Thus, developing more sustainable farming practices on a large scale is of utmost importance. However, information concerning the performance of farming systems under organic and conventional management in tropical and subtropical regions is scarce.   This study presents agronomic and economic data from the conversion phase (2007-2010) of a farming systems comparison trial on a Vertisol soil in Madhya Pradesh, central India. A cotton-soybean-wheat crop rotation under biodynamic,...

Sustainable Intensification of Tropical Agro-Ecosystems: Need and Potentials
Provedor de dados: 21
Autores: Andres, Christian; Bhullar, Gurbir S.
Rapid population growth, increasingly complex economies and novel industrial uses of agricultural products call for further intensification of agriculture, particularly in the tropics. How to achieve sustainable intensification of food production systems in tropical regions that are challenged by ongoing climate change, loss of natural resources and biodiversity is a matter of debate. Here we highlight the major knowledge gaps in agricultural research and policy that must be addressed to develop adequate governance and regulatory frameworks for sustainable agricultural intensification. They include quantification of the (i) value of (public/private) goods generated by ecosystem services, (ii) costs to conserve the natural resources and biodiversity that...

Soil Biological Activity Contributing to Phosphorus Availability in Vertisols under Long-Term Organic and Conventional Agricultural Management
Provedor de dados: 21
Autores: Bhat, Nisar, A.; Riar, Amritbir; Aketi, Ramesh; Iqbal, Sanjeeda; Sharma, Mahaveer P.; Sharma, Sanjay K.; Bhullar, Gurbir S.
Mobilization of unavailable phosphorus (P) to plant available P is a prerequisite to sustain crop productivity. Although most of the agricultural soils have sufficient amounts of phosphorus, low availability of native soil P remains a key limiting factor to increasing crop productivity. Solubilization and mineralization of applied and native P to plant available form is mediated through a number of biological and biochemical processes that are strongly influenced by soil carbon/organic matter, besides other biotic and abiotic factors. Soils rich in organic matter are expected to have higher P availability potentially due to higher biological activity. In conventional agricultural systems mineral fertilizers are used to supply P for plant growth, whereas...
