The long-term application of excessive chemical fertilizers has resulted in the degeneration of soil quality parameters such as soil microbial biomass, communities, and nutrient content, which in turn affects crop health, productivity, and soil sustainable productivity. The objective of this study was to develop a rapid and efficient solution for rehabilitating degraded cropland soils by precis...

introduction in agricultural ecosystems, organic fertilizers play an important role in producing sustainable agricultural production. considering this sajjadi nik et al (2011) reported that with increasing of vermicompost inoculation with nitroxin biofertilizer, capsule number per sesame plant increased, so that the most of capsule number per plant (124.7) was observed in 10 t/h vermicompost wi...

due to importance of nitrogen on the agronomic traits of linseed oil, a factorial experiment was conducted in randomized complete block design with three replications at the field research station of faculty of agriculture at shahrekord university in 2012. five different treatments of fertilizer including urea, azomin, nitroxin, supernitroplus and control (without nitrogen) as the first factor ...

recently, using the source of organic fertilizers and biofertilizers in sustainable crop production is growing. in order to evaluate the effect of organic compounds, biofertilizers and chemical fertilizer on morphological properties, yield and yield components of forage sorghum (sorghum bicolor) a field experiment was conducted in the research farm, college of agriculture, ferdowsi university o...

We studied nutrient balance in a paddy field that had a recycling irrigation system and evaluated the effect of the irrigation system on nutrient balance during the irrigation period, from April to August 2002. Chemical fertilizer was the main input of phosphorus; the soil absorbed about 56% of it. The amount of nitrogen supplied by the irrigation system was higher than in a representative padd...

Seeds of rice, jowar, ground nut and fingermillet were inoculated with microorganisms like Chaetomium globosum, Aureobasidium pullulans, Gliocladium roseum, Streptomyces sp. Pseudomonas pseudomallei YL-1 along with fertilizer (NPK 17:17:17) and were grown under laboratory conditions in earthen pots for forty five days. The phenotypic traits were analyzed and compared with control and fertilizer...
