The present investigation deals with the role of Plant Growth Promoting Rhizobacteria and chemical fertilizers alone or in combination on urease, invertase and phosphatase activities of rhizospheric soil and also on general impact on growth of safflower cvv. Thori and Saif-32. The PGPR (Azospirillum brasilense and Azotobacter vinelandii) were applied at 10cells/mL as seed inoculation prior to s...

A field experiment was conducted to assess the effect of farmyard (cattle) manure (FYM) and inorganic nitrogen (N) phosphorus (P) fertilizers on growth and tuber yield of potato (Solanum tuberosum L.). The treatments consisted of factorial combination of 4 levels of FYM (0. 10, 20 and 30 t h-1) and three levels of inorganic NP fertilizers (0, 33.3%, 66.6% recommended rates) laid out in a Random...

This Bulletin discusses several manufacturing processes for organic compound fertilizers overseas and in Taiwan. The different formulations of N-P2O5-K2O in the fertilizers are also reported. The yield response of different crops from the application of organic compound fertilizer reflects their superiority over organic fertilizers. Experiments also showed that the use of organic compound ferti...

ome organic fertilizers are suitable for greenhouse crops and can also fit the current ways of applying fertilizers commercially. However, not much information is available on plant response, nutrient supplying power, or the environmental impact of nutrient leaching with organic fertilizers. Not surprisingly, because of their differences in the makeup, levels of success in growing acceptable gr...

As a result of the studies carried out by Department Chemistry, Agrochemistry and Agroecology to improve physicochemical parameters sod-podzolic soils in conditions Pskov region, positive results were obtained. It was noted that on sandy loam soil period from 2016 2019, control option, there gradual increase acidity over years. For 5 years, exchange increased 0.1 units, hydrolytic 0.07 meq/100 ...

In this article, the influence of acidic effluent (AE) neutralization process, production raw fatty acids cotton soap stock, on change in applicability phosphate powder (PP) and mineralized mass (MM), which are low-grade phosphorites Central Kyzylkum, has been studied. It was found that with wide changes ratios AE : PP AE: MM (from 100:10 to 100:40) at a temperature 60 °C time duration 30 min, ...

This paper has substantiated the expediency and prospects of obtaining organomineral fertilizers by encapsulating mineral granules with an organic suspension in fluidized bed apparatuses. An overview existing approaches to mathematical description kinetics granule growth granulation processes apparatuses is presented. A model formation a hard shell around been built. It shows that depend on siz...

Agrochemical is evolved by the contraction and combination of words agricultural and chemical, and is a generic term used for the various chemical products typically used in agriculture. Agrochemicals essentially help in intensifying crop production and to reduce the effects of pests and parasites on farm animals. Agrochemical basically refers to the broad range of pesticides and fertilizers. A...
