Abstract:
[Truncated abstract] Weeds are a major limitation to agricultural and horticultural production and the main method of control is the use of herbicides. In addition to the resulting chemical pollution of the environment, the wide spread and continues use of herbicides have resulted in many weeds developing resistance to commonly used herbicides. This study investigated the potential of using green manures as a cultural method of control of weed invasion in agricultural fields. To understand the general mechanisms involved in the suppression of seed germination in green manure amended soils, see

Abstract:
Maintaining phosphorus (P) fertility in northern Great Plains (NGP) dryland organic cropping systems is a challenge due to high pH, calcareous soils that limit P bioavailability. Organic P fertilizers, including rock phosphate (RP) and bone meal (BM) are sparingly soluble in higher pH soils. Certain crops species have demonstrated an ability to mobilize sparingly soluble P sources. Objectives of this project were to 1) evaluate the effect of green manure (GM) crops and organic P fertilizers on the P nutrition of subsequent crops, and 2) investigate P fertility differences between organic and n

With shifting preferences of consumers towards healthier food, organic food demand has been on the rise for the past two decades. This increased demand has created an opportunity for farmers to shift from conventional to organic production. However, there are risks and uncertainties associated with organic farming. The management of an organic farm in the absence of organic-based disease and pest suppressing strategies constrains farmers from adopting organic vegetable production. The use of cover crops to control soil-borne diseases and suppress weeds and other pests has increased because of

Abstract:
The incorporation of cereal straw/stubble often immobilises nitrogen (N). This can help conserve N in soil in organic forms, thus reducing loss through leaching over dormant winter periods. However, N-depressions that arise during decomposition can reduce crop yield. The inclusion of a legume green manure can supply fixed-N, thus alleviating the low N availability to crops. In this study, the effect of lupin (Lupinus angustifolius L.) green manure incorporation on barley (Hordeum vulgare L.) straw/stubble decomposition, and N availability was investigated.

Human activities have doubled the loading of ecosystems with reactive nitrogen (N) contributing to many serious problems such as eutrophication, climate change and pollution. As most anthropogenic reactive N is created to supply plant-available N in agriculture, one of the ways to mitigate the situation is to improve N use efficiency in crop production. It is also potentially more sustainable to supply N to crops using biological N fixation (BNF) rather than synthetic N fertilisers, because BNF does not rely on energy from fossil fuels to create plant-available N.

Nos últimos anos os consumidores, em especial do mercado externo, estão interessados e preocupados cada vez mais com a segurança alimentar, principalmente no que se refere à forma de produção. Esse panorama tem motivado a busca por alternativas de baixo impacto ambiental. Uma delas é o uso de coberturas vegetais ou adubação verde. Nesse contexto a presente pesquisa teve como objetivo avaliar a influência do uso contínuo de coberturas vegetais em pomar de citros sobre os padrões de infestação e banco de sementes das plantas daninhas, assim como as características químicas do solo.
