This study describes the effects of balanced versus nutrient-deficiency fertilization on soil
microbial biomass, activity, and bacterial community structure in a long-term (16 years) field …

Salinity is among the most important abiotic stresses, which negatively affect growth, nutrient
uptake and yield of crop plants. Application of different micronutrients, particularly zinc (Zn) …

In this study, the effect of mineral fertilizer and organic manure were evaluated on soil
microbial biomass, dehydrogenase activity, bacterial and fungal community structure in a …

Most soils have relatively large contents of total potassium (K) but relatively small amounts of
plant‐available K+. Even though exchangeable K+ is considered to be one of the best …

The effects of mineral fertilizer (NPK) and organic manure on the community structure of soil
ammonia-oxidizing bacteria (AOB) was investigated in a long-term (16-year) fertilizer …

Crop land degradation is a common phenomenon in most regions of the world, especially in
arid and semi-arid regions. To mitigate cropland degradation and further enhance crop …

The combined long‐term effects of tillage method and crop rotation on crop yield have not
been studied in rainfed systems under Mediterranean climates. A field study was conducted …

Purpose Organic and inorganic fertilizers are used primarily to increase nutrient availability
to plants. Monitoring balanced versus unbalanced fertilization effects on soil microbes could …
