Organic farming is considered an effective means of reducing nitrogen losses compared with more intensive conventional farming systems. However, under certain conditions, organic farming may also be susceptible to large nitrogen (N) losses. This is especially the case for organic dairy farms on sandy soils that use grazed grass–clover in rotation with cereals. A study was conducted on two commercial organic farms on sand and loamy sand soils in Denmark. On each farm, a 3‐year‐old grass–clover… 

Nitrogen management in organic farming: comparison of crop rotation residual effects on yields, N leaching and soil conditions

After 3 years of different crop rotations in an organic farming experiment on a sandy soil in northwest Germany, spring triticale was cultivated on all plots in the fourth year to investigate

Symbiotic nitrogen fixation in organically managed red clover–grass leys under farming conditions

Abstract Symbiotic nitrogen fixation (SNF) by legumes is an important source of N to agriculture, particularly under organic farming conditions. The objectives of this study were to document amounts

Effects of two contrasting agricultural land‐use practices on nitrogen leaching in a sandy soil of Middle Germany

The objective of this study is to evaluate different agricultural land-use practices in terms of N leaching and to give recommendations for a sustainable agriculture on sandy soils in Middle Germany.

Nitrogen and Weed Management for Organic Sweet Corn Production on Loamy Sand

These results underscore the well-known potential for rapid nutrient loss on coarse soil and management challenges associated with asynchrony between organic N release and crop uptake, though limited potential for early season application on loamy sand.

Nitrate leaching risk is increased under exercise grazing in organic farming

ABSTRACT There is a trend in organic dairy farming towards higher milk yields associated with more concentrates and less grazing. Grazing is usually compulsory but grass intake from grazing varies

Management Effects on Quality of Organically Grown Winter Wheat

The study emphasizes the challenges in improving the quality of organically grown wheat beyond what is predetermined by environmental growth conditions and cultivar, and baking quality appeared better than could be expected from the quality parameters determined.

Influence of ley duration on the yield and quality of the subsequent cereal crop (spring oats) in an organically managed long-term crop rotation experiment

The ability to maintain crop yield and quality in systems based on nitrogen (N) fixed by legumes rather than from synthetic N fertilisers is fundamental to the long-term viability of organic farming.

Reduced nitrogen leaching by intercropping maize with red fescue on sandy soils in North Europe: a combined field and modeling study

AimTo study maize (Zea mays L.) growth and soil nitrogen (N) dynamics in monocrop and intercropped systems in a North European climate and soil conditions with the support of a simulation

Nitrate leaching in an organic dairy/crop rotationas affected by organic manure type, livestock densityand crop

Abstract. In dairy farming systems the risk of nitrate leaching is increased by mixed rotations (pasture/arable) and the use of organic manure. We investigated the effect of four organic farming

Nitrate leaching and growth of cereal crops following cultivation of contrasting temporary grasslands

If the N use efficiency of dairy farming systems is to be further improved the utilization of N during the pasture phase is crucial, and large differences in N-input during the grassland phase of the crop rotation had relatively little effect on the subsequent N release.

Nitrate leaching and N2-fixation in grasslands of different composition, age and management

The results from the present study indicate that the higher leaching losses observed in fertilized grass compared with unfertilized grass-clover systems were caused by a reduction in N2-fixation in grass-Clover over time, lowering the grazing intensity and the recycling of grassland N via animal excreta.

Carbon storage after long-term grass establishment on degraded soils

Recent concern about global warming has led to attempts to estimate the effects of management on carbon sequestration in soil. The objective of this study is to determine the amount of soil organic

A Simple Model for Estimation of Atmospherically-Derived Nitrogen in Grass-Clover Systems

ABSTRACT Atmospherically-derived nitrogen can be a major source of nitrogen in organic or other low-input farming systems. It is, however, in practice difficult to quantify the contribution of

Soil inorganic-N and nitrate leaching on organic farms

Nitrate-N and ammonium-N were both consistently low in the surface layers of fields in ley and accumulated in arable soils on some occasions when there was little or no crop uptake of N, after ploughing, and after very heavy applications of manure.

Effects of one to six year old ryegrass-clover leys on soil nitrogen and on the subsequent yields and fertilizer nitrogen requirements of the arable sequence winter wheat, potatoes, winter wheat, winter beans (Vicia faba) grown on a sandy loam soil

SUMMARY The largest yields of wheat and potatoes came from the combination of longer ley plus optimum fertilizer N but yields of winter beans were decreased where N had been given to the previous
