There seems to be conflicting information about foliar fertilizers and their timing of application to cotton. Much of the confusion lies in the variety of fertilizer products available. A cotton fanner now has a choice of applying foliar fertilizers (according to fertilizer labels) beginning at the first true leaf stage and continuing until defoliation. This newsletter will focus on available i...

Nitrogen is the most important essential nutrient that plays a major role in achieving maximum crop yield in agriculture. Therefore, nitrogen fertilizers such as ammonium sulfate and urea have been extensively used in modern agriculture. These fertilizers are generally oxidized to nitrate via nitrite by nitrifying microorganisms in the agricultural field (4, 10, 11). The serious environmental p...

BACKGROUND: Suitable and useful usage of different kind of fertilizers is the main way for reformation and potential of soil fertility and increasing of crops yield. Microelements are the critical elements for plants; also play the important role in crop productivity where it is used in low rate. Optimum plant nutrition and maximum yield is achieved when nutrient elements are a...

in order to evaluate row spacing and microelements spraying on yield and some morphological traits ofpeppermint, a split plot experiment was conducted based on randomized complete block design with fourreplications in sari agricultural sciences and natural resources university during 2010-2011. threelevels of row spacing (50 × 10, 50 × 20 and 50 × 30 cm) and two levels of microelements (no spra...

The state of ecology in the world, and as a result, requirements world community make agricultural producers turn to sustainable agriculture, which involves implementation measures aimed at eliminating preventing land degradation greening production along with biologization agriculture. Sustainable agriculture is based on competent use laws nature, scientific achievements, focused healing soil,...

The nutrient elements uptake in many of soils, is a problem because of high pH and plenty of calcium ions in them. Some of these elements are phosphorus and microelements. It is possible to increase absorption of these nutrient elements by addition of sulfur in soil and biological oxidation. The rate of this reaction is very slow and Thiobacillus bacteria are the most important oxidators of sul...

Target. Intensification of photosynthetic activity narrow-leaved lupine plants in order to increase the level crop grain yield by creating optimal conditions for their growth and development due combination technological process dose mineral fertilizers calculated planned foliar top dressing with during critical periods development, as well seed treatment before sowing inoculant a fungicide. Wa...

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...

Relevance. At present, the issues of mineral nutrition medicinal plants with essential elements remain unstudied, and lack certain microelements in soils is an underestimated agroecological factor. This necessitates study effect different doses zinc copper fertilizers on content mobile forms meadow-chernozem soil when cultivating Achillea millefolium L. Tanacetum vulgare southern forest-steppe ...

Devices on the basis of carbon nanotube (CNT) were not used extensively up to date [6]. That is connected with a problem of receiving the reliable, corresponding to the sizes and properties of CNT, electrode systems [7]. As a rule, usually represented CNT-devices contain other elements of the scheme, including electrodes, of the micron size. In devices on the base of CNT-array, electrodes can h...
