RESEARCH AND APPLICATION OF NON-TRADITIONAL ORGANIC FERTILIZERS

Nanostructured sewage sludge – highly-effective fertilizer-meliorant

Designed enzyme-cavitation method of bioremediation of waste water and deep processing of the resulting precipitate to the nanoscale. The method of creating different microcavitation medium for microorganisms, which ensure the destruction of organics. Nanostructured organic in processed sediment available plant roots and soil biota. The most important property of nanosediment – enormous sorption properties. When making such a pellet at a dose of 20 t/ha, high-arid conditions on light-brown soils are obtained high yields of winter wheat. Along with the precipitate was subject to field studies and deep primary tillage. The combination of deep chizel (37-40 cm) and the precipitate gives a good result, but the sediment is necessary to make the field on the surface of a layer of mulch. Due to this precipitate to accumulate sorption properties of air and atmospheric moisture. Also carried out experiments on the use of nanosediment in irrigated agriculture. To the residue was added natural meliorant - glauconite at a ratio of sediment and glauconite 10:1. It is found that the nanosediment sludge has versatile properties and water-saving solves the problem.

Effect of selenium on the productivity and quality of spring wheat under conditions of soil contamination with CAD

Effect of different methods of application of sodium Selenite on the yield and some quality indices of spring wheat varieties Zlata studied under conditions of soil contamination with cadmium. Installed that the greatest impact of selenium on the formation of grain productivity are more affected by presowing treatment of seeds and spraying of vegetating plants by sodium Selenite. In this case, when the seed treatment increased plant yield occurred as a result of increased attraversa ability of the ear, resulting in the improvement of the execution of kernels. When spraying vegetative plants revealed more and more bookmarks and the implementation of the reproductive organs that caused the growth in the number of kernels in ear. It should be noted that the indicators of quality of grain of wheat varieties Zlata largely influenced by the introduction of selenium in the soil. At the same time increased the contents of crude protein, indicating that the restoration processes of nitrogen in plants and its accumulation in grain as well as other processes productive use of nitrogen for protein synthesis.

Endogenous formation of nitrates in plants and role of some stress factors and selenium

The results of laboratory studies with triticale (X Triticosecale Wittm.) and wheat (Triticum aestivum L.) sterile seedlings in Petri dishes proving the possibility of endogenous formation of nitrates in plant tissues and the influence of external factors on this process are shown. The physiological expediency of the reduced nitrogen compounds to nitrate forms playing an indispensable role in the plant development, in particular direct or indirect (through a nitrogen monoxide) effect of nitrate to the plant stress resistance is discussed. The increase of endogenous formation of nitrates was observed in triticale and wheat sterile seedlings changing from the effects of high concentration salt solutions and some other stress factors and the influence of selenium on this process. The increase of nitrate content was noted in triticale 7 old days sterile seedlings more than 8 times in stress free conditions. In additional the increase of nitrate content was shown in wheat sterile seedlings more than three times in stress free conditions. Our studies also showed that the decrease endogenous formation of nitrates in wheat sterile seedlings using selenium with ammonium chloride and sodium chloride respectively 35% and 4 times.

Vladimir opolie agrogrey soils phosphorous potential buffer capacity and its relationship with mineralogical composition of the clay fraction

2NPK application reducing potential buffer capacity of soils, but it allows to support concentration of mobile phosphates at high level. 2NPK with manure application leads to reducing concentration of «reserved» phosphates forms, like in the control variant. In variants with moderate fertilizer application concentration of mobile phosphates, «reserved» phosphates forms and PBCP remains at a high level. Lime and manure application leads to the optimization of all parameters, except for the content of mobile phosphates – it is low. Fertilizer application increases the content of water-peptizationed clay and content of hydromicas, kaolinite and chlorite in it composition, but reduces content of mixed-layer minerals. Lime and manure application increasing concentration of aggregated clay.

Keywords: the effect of fertilizer application, long field experiment, phosphorus mobility factor, PBCP by K.E. Ginzburg, the total reserve of mobile soil phosphate, water-peptizationed clay, aggregated clay, x-ray diffractometrics.
