This paper reviews the original reasons of the organic farming movement for excluding mineral (inorganic) fertilizers. In this paper, their theories and decision criteria for excluding use of inorganic fertilizers in crop production were revisited. Original reasons for banning inorganic fertilizers were subjected to scientific scrutiny, which was not possible when they were formulated 50–100 years ago due to limited knowledge of the soil-crop system. The original reasons were as follows: Rudolf…

Nutrient use efficiencies and leaching of organic and conventional cropping systems in Sweden

Measurements of leaching and crop uptake of N, P, and K and determinations of mineral N in soil were conducted during a 6-yr period in two organic crop rotations, one with and one without addition of animal manures to suggest that N use efficiency is improved if inorganic N fertilizers are used rather than green manures, especially in combination with cover crops.

Why organic farming is not the way forward

The aim of this article is to provide information about crop production data based on large-scale organic farming and to point toward major consequences. National statistics show lower organic yields

Nitrogen Fertilizer Suppresses Mineralization of Soil Organic Matter in Maize Agroecosystems

The possibility that N fertilizer increases soil organic matter (SOM) mineralization and, as a result, reduces SOM stocks has led to a great debate about the long-term sustainability of maize-based

Synthetic nitrogen fertilizers deplete soil nitrogen: a global dilemma for sustainable cereal production.

A major global evaluation of current cereal production systems should be undertaken, with a view toward using scientific and technological advances to increase input efficiencies, and the input of ammoniacal N should be more accurately matched to crop N requirement.

The Contribution of Commercial Fertilizer Nutrients to Food Production

technology and intensified production often involve a greater need for commercial fertilizer nutrients to avoid Nutrient inputs in crop production systems have come under innutrient depletion and

Strategies for carbon sequestration in agricultural soils in northern Europe

Abstract We present new and synthesize published results from long-term field studies exploring management options for carbon sequestration in cropland and grassland. Agricultural practices were
