The bacterial endophytic communities residing within roots of maize (Zea mays L.) plants cultivated by a sustainable management in soils from the Quechua maize belt (Peruvian Andes) were examined using tags pyrosequencing spanning the V4 and V5 hypervariable regions of the 16S rRNA. Across four replicate libraries, two corresponding to sequences of endophytic bacteria from long time maize-culti...

Approaches to soil management, including problems of soil degradation and low soil fertility, have recently undergone major changes. The former view was to concentrate on achieving high levels of production from the more fertile areas, leaving the marginal lands for extensive use only. Steeply sloping and highly drought-prone areas were preferably not to be cultivated at all. Soil constraints w...

field study was conducted at five villages of botswana namely, tsabong, tshane, mathathane, motlhabaneng and tsetsejwe during the periods of june to august 1999 and june to august 2000. the objective of the study was to assess and compare the soil physicochemical properties of soils at the five villages and to study the effect of cultivation on some soil physical properties. parameters measured...

Accurate assessment of soil loss is essential for sustainable agricultural production, 11 management and conservation planning, especially in productive rain-fed agro-ecosystems 12 and protected areas. The European Union considers soil as a non-renewable resource and 13 identifies that soil degradation has strong impacts on soil and water resources. In this work the 14 Revised Universal Soil Lo...

abstract phosphorus (p) sorption in soils is a key process governing the availability of p to crops. p sorption characteristics and their relationship to soil properties were determined in twenty-one paired surface soil samples (21 cultivated and 21 adjacent virgin soils) belonging to five soil types: typic calcixerepts, typic haploxerepts, typic endoaquepts, vertic endoaquepts, and vertic calc...

This greenhouse experiment aimed to investigate the effects of poultry manure (PM) on the growth of oat plant (Avena sativa) and removal of total petroleum hydrocarbons (TPHs) from soil. The treatments consisted of three TPH levels (4%, 6%, and 8% w/w) and two PM levels (zero and 1%) at three replications. According to the findings, shoot height, number of leaves, and the fresh and dry...

We investigated the interactive effects of plant domestication and perennial cultivation on diversity and richness of plant-parasitic nematode (PPN) communities associated with highbush blueberry (Vaccinium corymbosum). Rhizospheric soil of V. corymbosum plants was sampled in coupled wild and cultivated sites within the Pinelands National Reserve. Although PPN diversity was higher in cultivated...

The chernozem has high productivity, most of which is located in Northeast of China. Considering the restrictions of land use and terrain and meteorological conditions, soil erosion and degradation often result in lower agricultural output than expected. Land consolidation is served to consolidate parcels and to enlarge holdings as well as included provisions such as irrigation, drainage infras...

Lonicera confusa was a medical plant which could adapt to the Ca-rich environment in the karst area of China. The photosynthesis, relative chlorophyll content,differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) of L. confusa that cultivated in calcareous and sandstone soils were investigated. The results showed that the relative chlorophyll content and net photosy...
