Continuous cropping is a common agricultural practice in the word. In China, farmers often apply excessive fertilizers to fields in an attempt to maintain yields in continuous cropping systems. However, this practice often results in high nutrient concentrations in soils, nutrient pollution in

The Gonghe Basin region of the Tibet Plateau is severely affected by desertification. Compared with other desertified land, the main features of this region is windy, cold and short growing season, resulting in relatively difficult for vegetation restoration. In this harsh environment,

To determine how plantations of Caragana microphylla shrubs affect saline-alkali soil amelioration and revegetation, we investigated the vegetation and sampled soils from saline-alkali wasteland (SAW), perennial Caragana forestland (PCF), Caragana forest after fire disturbance (CFF). Results showed

The genetic diversity of 88 Caragana nodule rhizobial isolates, collected from arid and semi-arid alkaline sandy soils in the north of China, was assessed by PCR-RFLP of the 16S rRNA gene and the 16S-23S IGS, as well as the phylogenies of housekeeping genes (atpD, glnII and recA) and symbiotic genes
