A 10-year-long field trial (between 2001 and 2010) was conducted to investigate the effect of paddy-upland rotation on rice yield, soil properties, and bacteria community diversity. Six types of paddy-upland crop rotations were evaluated: rice-fallow (control; CK), rice-rye grass (RR), rice-potato with rice straw mulches (RP), rice-rapeseed with straw incorporated into soil at flowering (ROF), rice-rapeseed incorporated in soil after harvest (ROM), and rice-Chinese milk vetch (RC). Analysis of terminal restriction fragment length polymorphism (T-RFLP) was used to determine microbial diversity among rotations. Rice yield increased for upland crops planted during the winter. RC had the highest average yield of 7.74 t/ha, followed by RR, RP, ROM, and ROF. Soil quality differences among rotations were found. RC and RP improved the soil mean weight diameter (MWD), which suggested that rice rotated with milk vetch and potato might improve the paddy soil structure. Improved total nitrogen (TN) and soil organic matter (SOM) were also found in RC and RP. The positive relationship between yield and TN/SOM might provide evidence for the effect of RC rotation on rice yield. A strong time dependency of soil bacterial community diversity was also found.

Long Term Treatment

The soil microbial community research conducted in the field has focused on the genetic diversity of these organisms. In this study, we assessed the proteins expressed in soil microbial communities following the long-term application of mineral fertilizer (NPK) and organic manure (M) to paddy soil, indirect extraction method and separated via two-dimensional (2D) gel electrophoresis and identified using a matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) approach. We found that the number of cells in the primary soil in the M treatment was significantly greater than in the NPK and CK treatments. The numbers of cells extracted were consistent with the total cell numbers and the concentration of extracted proteins (CK < NPK < M). 303 and 306 protein spots being detected in the CK map and NPK map, respectively. Eleven spots of interest were identified in the 2D gels, including 8 different protein spots and 3 unique protein spots. Three common proteins involved in protein hydrolysis and glutamate synthesis and metabolism. Eight differentially expressed proteins involved in DNA replication, transcription, protein folding and energy metabolism, the processes of cofactor and vitamin metabolism, transcriptional regulation, recombination and xenobiotic compound biodegradation and metabolism. The long-term application of fertilization resulted in significant changes in the microbial community structure and function, and the long-term application of pig manure significantly increased the microbial biomass and the functional and structural diversity in the soil. It is very interesting to address the MS identification of intracellular proteins from microbial communities under different fertilizer treatments in a paddy soil.

Agricultural Use

Проаналізовано процес трансформації у динаміці водно-фізичних показників осушуваних торфових ґрунтів під впливом довготривалого інтенсивного сільськогосподарського використання. Зміна параметрів будови торфового ґрунту визначає спрямованість еволюційного процесу в динаміці водно-фізичних констант. Найбільш ефективні параметри будови торфового ґрунту та водно-фізичні властивості формуються у разі впровадження монокультури багаторічних трав, трав’яно-просапних та зерно-трав’яно-просапних сівозмін. Складність раціонального використання осушуваних торфових ґрунтів в переведенні їх потенційної родючості в ефективну. The process of transformation in the dynamics of hydrophysical properties of drained peat soils under the influence of long-term intensive agricultural use is analyzed. Transformation of the structure parameters of the peat soil determines the orientation of the evolutionary process in the dynamics of hydrophysical constants. The most effective parameters of the peat soil structure and hydrophysical properties are formed when introducing single-cropping of perennial grass, herb-cultivated and corn-herb-cultivated crop rotation. The complexity of rational use of the drained peat soils is in transformation of their potential fertility into effective.

Positive Effect

The results of long-term research in experiments with crop rotations with different clover saturation are presented. It is shown that the cluster has a positive effect on the main indicators of vegetation of dark-gray forest soil. The introduction of two fields of perennial grasses into the six-field crop rotation significantly increases both the humus reserves and increases the productivity of arable land by 1.5–2 times compared to the crop rotation with a field of pure steam.
