The article discusses the influence of the main fertilizer in combination with additional fertilizing on the feeding regime of soil and productivity of “Kazanskaya 560” winter wheat variety. The provision of soil with available nutrients is achieved through the rational use of fertilizers in crop rotations. In 2010-2012 an additional fertilizing by Humate “Bioplant Flora” at a rate of 2 litre per hectare in autumn increased yield to 4.6-5.5 centner per hectare, depending on the background of the basic fertilizer. Additional spring fertilizing in early plant growth by Bioplant Flora on the background of autumn feeding practically does not increase the yield of winter wheat. Fertilizing with ammonium nitrate at a rate of 1.5 center in share weight per hectare increased the average yield to 2.1-2.4 tons per hectare for the period 2010-2012, depending on the background of the main treatment. In favorable 2011 it increased the yield to 1.5-3.5 centner per hectare. Adding NPK at sowing in rows at 1 centner per hectare in share weight increases yields to 3.5 centner per hectare without feeding, to 7.5 centner per hectare with the autumn fertilizing by Bioplant Flora, to 5.6 centner per hectare with the spring fertilizing with ammonium nitrate, comparing with the background without fertilizers. Thus, the differential application of the basic fertilizer, combined with fertilizing, improves the soil nutrient status and facilitates the formation of a predetermined amount of yield.

Soft Winter Wheat

The studies were carried out in the southern part of the Rostov region in 2017-2019 on typical carbonate chernozem. Studied was the efficiency of periods of ammonium nitrate application (N30, N30+30 ) in autumn when the vegetation season is finished, in spring in the thawed soil, and during the tillering phaseon the yield and quality of winter wheat grain of Krasa Dona variety by different seed sowing rates (500, 600, 700 pcs/m2). Soft winter wheat variety Krasa Donacultivated after sunflower has shown a good reaction to double nitrogen top-dressing in autumn and in spring (N30 in autumn when the autumn growing season is finished + N30 in spring on thawed soil). In this variant there has been formed the largest yield of 6.09-6.18 t/ha. The productivity excess over the control variant (without nitrogen top-dressings) was 2.38-2.63 t/ha, depending on the seeding rate, which significantly exceeded the level of LSD05 in the experiment (LSD05 = 0.24 t/ha). In addition, in this variant with the seeding rate of 500 pcs/m2 the maximum economic efficiency was obtained. The profitability was 121.3 %, and the contingent net income was 34,268 rub/ha. The application of nitrogen fertilizing provided an increase in the mass of 1000 grains to 42.6-43.0 g (39.8-40.2 g in the control) and increased the gluten content in the grain to 20.5-21.8 % (18.6-18.8 % in the control).

Field Variability

<p>The EU Water Framework Directive (WFD) aims to target prevalent poor water quality status. Of the various contributing sources agriculture is particularly important due to the high loading rates of sediment and nutrient losses associated with fertilisation, sowing, and cropping regimes. Understanding soil nutrient status and the potential pathways for nutrient loss either through point or diffuse sources is an important step to improve water quality from an agricultural perspective. Research has demonstrated extensive in-field variability in soil nutrient status. A sampling regime that explores this variability at a sub-field scale is necessary. Traditional soil sampling consists of taking 20-30 cores per field in a W-shaped formation to produce a single bulked core, however, it generally fails to locate nutrient hotspots at finer resolutions. Inappropriate generalised fertilisation and management recommendations can be made in which nutrient hotspots or deficient zones are overlooked. Gridded soil sampling can reveal the full degree of in-field variability in nutrient status to inform more precise and site-specific nutrient applications. High soil phosphorus levels and the concept of legacy nutrient accumulation due to long-term over-application of phosphorus fertiliser in addition to animal slurry is a problem across the island of Ireland.</p><p>This research aims to locate and quantify the presence of soil nutrient hotspots at several field-scale locations in the cross-border Blackwater catchment in Northern Ireland / Republic of Ireland. Based on 35 m sampling grids, the nutrient content at unsampled locations in each field was determined using GIS interpolation techniques. Particular attention was paid to phosphorus, given its role in eutrophication. Gridded soil sampling enables the identification of nutrient hotspots within fields and when combined with an analysis of their location in relation to in-field landscape characteristics and knowledge of current management regimes, the risk of nutrient or sediment loss potential may be defined. This research concluded that traditional W soil sampling of producing one average value per field is not appropriate to uncover the degree of spatial variability in nutrient status and is inappropriate for catchment management of agricultural systems for controlling nutrient losses. Soil sampling at multiple locations per field is deemed to be cost-prohibitive for many farmers. However, sub-field scale soil sampling and appropriate geostatistical interpolation techniques can reveal the degree of variability and suggest an appropriate resolution for field-scale nutrient management that may be necessary to achieve measurable improvements in water quality.</p>
