“…In our dataset, > 90% of the parcels could be re-identified from one year to the next. So, IACS offers valuable and viable insight into agricultural practice and land use (sensu Longueville et al 2007, Leteinturier et al 2006, Schönhart et al 2011). According to crop diversity, the north-western part of the study region is dominated by 1 to 2 relevant crops, which is characterized by a high share of maize in arable area.…”

“…Each farmer willing to receive direct payments has to offer information on field size and crops grown on each field in every year of participation. First attempts of studying this type of data were made by Leteinturier et al (2006) in the Wallon region (Belgium) and Schönhart et al (2011) in the Mostviertel region (Austria). Nitsch et al (2012) demonstrated the informational surplus on the basis of grassland transition in Germany.…”

Crop sequence patterns are considered as those schemes farmers apply within a single field to succeed crops over time, regardless of whether the same crop is grown continuously or a diverse rotation is used. This study aimed at identifying these patterns for a large and representative area in Northern Germany during a six-year period from 2005 to 2010. The analysis was carried out for the entire federal state of Niedersachsen (Lower Saxony) which has 1.8 million hectares of arable area.Field data was obtained by the Integrated Administration and Control System (IACS), which was developed for the administration of the European agricultural direct payments. So far, German IACS has not been exploited in the light of agronomical practice. In total, the available data comprised about 990 000 records for each year, each representing a single field out of the study region. Throughout the analysis, different agronomic and temporal scopes resulted in a different number of fields being accessible for evaluation. Ten major arable crops and crop groups were considered for the study; 184 701 fields representing 645 870 ha of arable area could be analyzed to identify crop sequence patterns over the six years. Thus, 16 836 combinations of the 10 major crops occurring in time and space could be described. Thereof, 12 crop sequence patterns were found covering 55.6% of arable area. For 2010, 619 447 fields representing 1 730 564 ha of arable area, were analyzed with regard to their respective crops and pre-crops. Maize, winter wheat, sugar beet, oilseed rape and potatoes were studied with special emphasis. On average, 46.9% of maize area were cropped following maize as a pre-crop. For winter wheat, self-sequences were identified on 30.0% of arable area. Oilseed rape and sugar beet are generally grown in typical rotations. However, 24.6% of arable crop area were considered as having a pre-crop which might be disadvantageous for crop health.Due to a rapid increase of maize area in the region, crop sequence patterns are undergoing a dramatic shift. It is concluded that a large proportion of arable area is potentially threatened by risks of pest and disease outbreaks as well as by economical over-reliance in a few cash crops. We demonstrate, that administrative data could offer many insights in agronomical trends and practices and should, therefore, be analyzed in more detail.

“…고대로부터 시작된 윤작은 토양의 비옥도를 높이고 병해 충과 잡초의 발생을 줄이기 위한 수단으로서 저투입 농업기 술의 하나로 간주 된다 (Kang, 2007;Leteinturier et al, 2006;White, 1970). 그러나 산업의 발달과 함께 화학비료와 합성농약을 이용한 농업의 생산성이 '녹색혁명'이라는 이름 으로 크게 향상된 이후, 단순한 윤작중심의 농업방식은 전근 대적인 농업기술로 인식되는 경향이다 (Klinkenborg, 2012).…”

Soil microbes are widely well known to play an important role for sustainable agriculture in terms of crop healthy cultivation and environmental conservation. In this context, the distributional characteristics of soil microbes according to cropping systems were investigated under rice (R)-rice (R), rice (R)-barley (B)-rice (R), and soybean (S)-barley (B)-soybean (S) cropping condition to get basic informations for sustainable agriculture, where barley was grown for winter, in mid-mountainous loam paddy located at the altitude of 285 m above sea level in Sangju area from 2014 to 2015. Estimating from microbial communities by fatty acid methyl ester (FAME) method, a total biomass of bacteria, actinomycetes, and fungi in R-B-R plot was 37% and 40% higher than that in S-B-S and R-R plots, respectively (p < 0.05). In especial, bacteria and fungi were more in R-B-R plot than those in any other ones. B. japonicum, AMF, and mesophilic Bacillus sp. were also greater in S-B-S plot than those. In the community distribution, however, bacteria and actinomycetes showed comparatively high values in S-B-S plot relative to either R-R or R-B-R plot including rice, in which fungi outstanding. In the correlation between microbial biomass and soil properties changed by the cropping, bacteria was positively correlated with C:N ratio; actinomycetes with exchangeable Ca; fungi with available P 2 O 5 (p < 0.05). While these microbes showed negative response to water stable aggregates of soil.

“…Crop rotation is characterized by a cycle period, while crop sequence is limited to the order of appearance of crops on the same piece of land during a fixed period (Leteinturier et al, 2006). Crop rotation is along used concept in models to represent the temporal dimension of cropping plan decisions (Heady 1948).…”

“…Crop rotation as a particular crop sequence is therefore a natural starting point in designing cropping systems that are stable over time (Vereijken, 1997). Crop rotation is considered as being essential for integrated farming (Stoate et al, 2001) and is in contradiction with mono cropping as a sustainable solution for farms (Leteinturier et al 2006). The concept of crop rotation is an interesting means of obtaining a succession of crops year after year on a specific piece of land.…”

In china, the farmland transfer makes various farmer specialized cooperatives (FSC) take possession of largescale farmland. In order to carry out large-scale production and intensive management, on the base of the land resources, agricultural information, and production technology, the FSC wants to make decisions on the selection of crops and their allocation to farmland (cropping plan problem) and on the temporal successions of crops over the years (crop rotation problem). In this paper, we propose the model of cropping plan decision. Firstly, based on the spatial-temporal and time flexible characteristics of crops, the network model of cropping plan is built. Secondly, through analyzing the network flow balance problems, the constraint conditions are derived, and the network model is optimized to get the linear model. Thirdly, considering the influence factors of crop productivity, the linear model is extended by establishing nonlinear constraints and objective function. Finally, the numerical example is provided to illustrate the process about making cropping plan decision. The results of the numerical example show that it is beneficial to improve the quality and output of crops, and increase economic benefit, if the model is applied to formulate scientific and reasonable cropping plan by the FSC.
