“…They also provide useful amounts of organic matter, as well as non-leguminous crops which, nevertheless, cannot fix atmospheric N 2 (Davies and Lennartsson, 2005). During 32 years of winter wheat cropping, Procházková et al (2003) found higher average yields with green manuring compared with straw incorporation into the soil, probably due to a slower decomposition and following release of nutrients by the latter.…”

Agronomy for Sustainable Development, Springer Verlag/EDP Sciences/INRA, 2010, 30 (2), <10.1051/agro/2009040>. Agron. Sustain. Dev. 30 (2010) Abstract -Common agricultural practices such as excessive use of agro-chemicals, deep tillage and luxury irrigation have degraded soils, polluted water resources and contaminated the atmosphere. There is increasing concern about interrelated environmental problems such as soil degradation, desertification, erosion, and accelerated greenhouse effects and climate change. The decline in organic matter content of many soils is becoming a major process of soil degradation, particularly in European semi-arid Mediterranean regions. Degraded soils are not fertile and thus cannot maintain sustainable production. At the same time, the production of urban and industrial organic waste materials is widespread. Therefore, strategies for recycling such organic waste in agriculture must be developed. Here, we review long-term experiments (3-60 years) on the effects of organic amendments used both for organic matter replenishment and to avoid the application of high levels of chemical fertilizers. The major points of our analysis are: (1) many effects, e.g. carbon sequestration in the soil and possible build-up of toxic elements, evolve slowly, so it is necessary to refer to long-term trials. (2) Repeated application of exogenous organic matter to cropland led to an improvement in soil biological functions. For instance, microbial biomass carbon increased by up to 100% using high-rate compost treatments, and enzymatic activity increased by 30% with sludge addition. (3) Long-lasting application of organic amendments increased organic carbon by up to 90% versus unfertilized soil, and up to 100% versus chemical fertilizer treatments. (4) Regular addition of organic residues, particularly the composted ones, increased soil physical fertility, mainly by improving aggregate stability and decreasing soil bulk density. (5) The best agronomic performance of compost is often obtained with the highest rates and frequency of applications. Furthermore, applying these strategies, there were additional beneficial effects such as the slow release of nitrogen fertilizer. (6) Crop yield increased by up to 250% by long-term applications of high rates of municipal solid waste compost. Stabilized organic amendments do not reduce the crop yield quality, but improve it. (7) Organic amendments play a positive role in climate change mitigation by soil carbon sequestration, the size of which is dependent on their type, the rates and the frequency of application. (8) There is no tangible evidence demonstrating negative impacts of heavy metals applied to soil, particularly when high-quality compost was used for long periods. (9) Repeated application of composted materials enhances soil organic nitrogen content by up to 90%, storing it for mineralization in future cropping...

“…Nevertheless, many agricultural companies have no animal production or have significantly decreased production of farmyard fertilizers. Organic fertilization then may be replaced with straw left in the field after the harvest of cereals, although the effect of straw application on yield reported in literature is rather low (Powlson et al 1985, Thomsen and Jensen 1994, Procházková et al 2003). Yet, a positive influence of straw on soil properties was observed (Christensen 1986, Powlson et al 1987, Ocio et al 1991, Černý et al 2003).…”

In long-term stationary experiments under different soil-climatic conditions, an influence of mineral and organic fertilization on yield of winter wheat, spring barley and potato tubers was evaluated. Statistically significantly lowest grain yields of winter wheat (4.00 t/ha) and spring barley (2.81 t/ha) were obtained in non-fertilized plots at all experimental sites. In the case of potatoes, the lowest yield of dry matter (5.71 t/ha) was recorded in the control plot, but the result was not statistically significant. The manure-fertilized plot gave the average yield of wheat higher by 30%, of barley by 22%. Application of sewage sludge resulted in wheat yield higher by 41% and barley yield higher by 26% over control. On average, application of sewage sludge and manure increased the yield of potatoes by 30% over control. The highest yield was obtained after application of mineral fertilizers; average yield increased by 59, 50 and 36% in winter wheat, spring barley and potatoes, respectively. No statistically significant differences among the plots with mineral fertilizers were observed. At different sites, the yield of studied crops varied; however, the effect of fertilization on yield increments was similar at all experimental sites except for Lukavec. It is the site with the lowest natural soil fertility, and it showed the highest effect of the applied fertilizers.

“…Rothrock and Cunfer (1986) and Maas and Kotze (1990) showed that the number and kind of microorganisms antagonistic against Gaeumannomyces graminis changed under the influence of different plants in crop rotation. Procházková et al (2003) found that wheat yield was not significantly affected by continuous cropping and the high production ability of wheat in the long-term experiment showed a high antiphytopathogenic potential of the soil under study.…”

The effect of crop rotation and monocropping on the occurrence of bacteria with antagonistic activity toward Pythium debaryanum and Fusarium oxysporum was shown. Arthrobacter spp., fluorescent Pseudomonas spp. and actinomycetes were isolated from winter rape, sugar beet and winter barley rhizosphere and bulk soil from the plots of a long-term crop rotation experiment (18 years). The occurrence of mycoantagonistic isolates and their antibiosis level exhibited specificity for the site, crop and crop rotation. Mycoantagonistic activity was common among actinomycetes and fluorescent Pseudomonas spp. and less frequent among Arthrobacter spp. Antibiosis of fluorescent Pseudomonas spp. and Arthrobacter spp. was in general stronger against P. debaryanum than F. oxysporum. The highest percentage of antagonistic Pseudomonas spp. against P. debaryanum was in the plots of barley crop, while plots of winter rape showed higher frequency of antagonists against F. oxysporum. The highest antibiosis activity of Arthrobacter spp. against both pathogens occurred in isolates from barley and winter rape monoculture, and there were no F. oxysporum antagonists among these bacteria in sugar beet monoculture. Most of actinomycete isolates strongly inhibited growth of P. debaryanum and F. oxysporum. The percentage of mycoantagonistic actinomycetes and their antibiosis level were the highest in the 6-year crop rotation system.
