reliance nitrogen fertilizers biological nitrogen fixation
2020/4/3
Crop yields have increased substantially over past decades, along with increasing use of nitrogen fertilizer. While nitrogen fertilizer benefits crop growth, it has negative effects on the environment...
Potassium fixation in soil size fractions of arid soils
calcareous soils Iran smectite soil fractionation
2015/3/9
Amounts of potassium (K) fixed in soil fractions of 10 calcareous soils of southern Iran were measured to evaluate the contributions of different soil size fractions to K fixation. Soil particles were...
Effect of mycorrhizal inoculation on growth, nitrogen fixation, and nutrient uptake in Cicer arietinum (L.) under salt stress
Cicer arietinum Glomus mosseae growth nitrogenase
2011/6/29
Most legumes in natural conditions form a symbiosis with arbuscular mycorrhizal (AM) fungi. AM fungi in saline soils have been reported to improve salinity tolerance and growth in plants.
