Effect of organic and chemical amendments on some nutrients concentration of soil and pistachio leaf at field condition

Azam Razavi Nasab; Amir Fotovat; alireza astaraie; ahmad tajabadipour

Volume 42, Issue 1 , May 2019, Pages 47-59


  Introduction Pistachio is one of the most economical cash crops in Iran that is located in arid and semi-arid regions with low soil organic matter and very harmful ions. The enhancement of the organic matter in sufficient quantity and quality plays an important role in agricultural production and soil ...  Read More

Research Paper Soil Chemistry and Pollution
The effect of carbon black and hair waste on heavy metals uptake and some growth parameters of lettuce and spinach irrigated with metal contaminated water

Vafa Bozar; Nafiseh Rang Zan; Habibollah Nadian Qomsheh

Volume 42, Issue 1 , May 2019, Pages 61-80


  Introduction Soil quality is very important because of the direct impact on agricultural production and the nutrition of living creatures. The use of urban and industrial wastewaters (as lower quality water for irrigation of plants to reduce raw water consumption) can lead to a gradual accumulation of ...  Read More

Research Paper Soil Biology, Biochemistry and Biotechnology
The effect of pseudomonas sp and enterobacter cloacae on the distribution of carbon forms in the soil under corn and wheat cultivated in rhizobox

Marzieh Mazraeh; Roya Zalaghi; Naiemeh Enayatizamir

Volume 42, Issue 1 , May 2019, Pages 81-93


  Introduction Growth-stimulating bacteria are now proposed as an alternative to chemical fertilizers in order to increase soil fertility in sustainable agriculture. Biofertilizers are also expressed as microbial inoculants that are capable of removing soil nutrients from an inaccessible state through ...  Read More
