Response of Soybean to Hydrochar-Based Rhizobium Inoculation in Loamy Sandy Soil

Soybean Response to Drought and Seed Inoculation

Drought is one of the most important factors that limits N fixation, growth and yield of soybean. 2 The aim of this study was to determine the effects of water stress, starter N application and seed inoculation on yield and yield components of soybean (cv. Williams). The experiment was conducted in 2010 at the Islamshahr town that located in 12 km of South-west of Tehran, the capital of Iran. T...

Response of Chickpea to Rhizobium Inoculation I. Nitrogen Fixation

Investigating the Effect of Zeolite on the Coefficients of Soil Moisture Curve Models in Two Sandy and Loamy Texture

One of the important elements in mechanized irrigation is to know the relation between suction force (matric force) and soil moisture, which is referred to as moisture curve. The shape and coefficients of this curve are influenced by the texture and structure of the soil and can change with soil structure modification.  The most important goals of this study were to evaluate the effect of using...

Response of microbial activities to heavy metals in a neutral loamy soil treated with biosolid.

Application of biosolid on land has been widespread in numerous countries for last several decades. This study performed incubation experiments by mixing a neutral loamy soil and biosolid enriched in Cu, Pb and Zn to explore how heavy metal affects soil mineralization and microbial biomass. The experimental results indicated that large nutrient, microorganism and C sources from biosolid were be...
