The article examines the effect of organic and mineral fertilizers on the accumulation of total nitrogen, phosphorus and potassium in the surface mass of alfalfa in the gray-meadow soils, which have long been irrigated and poorly supplied with nutrients in the Karabakh region. issues were commented: Provision of plants with essential nutrients during the growing season, productivity, product quality depends on the availability of easily digestible nutrients in the soil. In order to get high yields from agricultural crops, organic and mineral fertilizers should be applied to the soil every year in accordance with the norms established on the basis of soil cartograms, and cultivation techniques should be properly followed. The optimal diet for alfalfa depends on the optimization of fertilizer rates in different irrigations. The highest amount of total NPK was observed in the first form over the years and decreased in subsequent forms. Each of the formations in the surface mass was high in nitrogen and potassium, and low in phosphorus. In the 2nd and 3rd years of alfalfa condition, the total NPK was higher than in the first year in terms of formats. This is due to the fact that alfalfa increases the amount of nutrients in the soil and soil fertility. It also has a positive effect on the regulation of nutrients in the surface mass of alfalfa.

The problems of impact of organic and mineral fertilizers on gathering of total nitrogen, phosphorus and potassium in the lucerne surface mass in coating planting of the grey–meadow soils which are weakly provided with the nutrient under the condition of Karabakh region were commented. Provision of plants with the main nutrient during the vegetation, productivity, crop quality depends on supply of the nutrient which is easily assimilated. In order to get high yields from agricultural plants, the organic and mineral fertilizers must be applied to a norm which was fixed on the basis of soil cartograms, the cultivation agrotechnics must be correctly fulfilled every year. The good food regime for the lucerne depends on optimization of fertilizer norms in different irrigation. The highest quantity of total NPK was observed in the first mowing, but it reduced in the next mowing’s. Nitrogen and potassium is high in each of the mowing’s, but phosphorus is little on the surface mass. This is due to increase of the nutrient quantity of lucerne and soil fertility. This positively influences on nutrient regulation on the surface mass over the mowing’s in lucerne plant.

The influence of systematic application of mineral fertilizers, on the background (BG) of the after-effect of 30 t on ha of manure, on the content of nutrients in spring wheat plants of “Myronivska Yara” regional variety and winter wheat plants of “Myronivska 61” variety, and on nutrients removal by plants, during cultivation on Meadow-Chernozemic Carbonate Soil, was studied. The results indicate a close relationship between external conditions and internal metabolic processes in winter and spring wheat plants. Thus, a balanced ratio of nitrogen, phosphorus and potassium provides a more intensive supply of these elements from the soil, what increases their content in plants. The highest content of total nitrogen, phosphorus and potassium in winter wheat plants was observed in the variant, where 1.5 rate of mineral fertilizers was applied with the background of 30 t on ha of manure, in the tillering phase and was 4.86; 2.17; 3.48 %, respectively, what is almost 2 times higher, than the control. During the growing season, the nutrients content in all variants decreased. The same pattern was observed in plants of spring wheat. The maximum nutrients content was recorded in all variants in the phase of spring tillering, and also was recorded significant reduction in their adsorption from the soil and using by plants during the growing season. The content of total nitrogen in spring wheat plants in the tillering phase fluctuated in fertilized variants in the range of 2.21-2.51 %, compared with the control – 2.10 %; phosphorus – in the range of 1.20-1.47 %, compared with the content on the control – 1.04 %; potassium – 1.88-3.08 %, in the control, respectively – 1.68 %. The results of research indicate, that long-term application of fertilizers in crop rotation affects, as a result, also on the removal of nutrients with the crop. Thus, the removal of basic nutrients by plants of winter and spring wheat was the highest in the variant “BG + N110P120K120”. Under winter wheat it was 210 kg on ha N, 122 P2O5, 157 kg on ha K2O, compared with the control variant – 86.3 N, 48.2 P2O5, 57.8 kg on ha K2O. Under the spring wheat it was 119 N, 66.4 P2O5, 85.4 kg on ha K2O, and in control variant, respectively, – 46.6 N, 26.5 P2O5, 32.8 kg on ha K2O.

Long-term observations of the drained soil of peat-podzolic-gley light loam on ancient alluvial sands state on the example of the meliorative object "Tinky-2" showed that under the influence of agricultural use in the soil, the organic matter mineralization processes are accelerated. During the drainage process, the soil evolutionarily suffered the following changes: the peat layer was compacted, humified and mineralized, which was a reason of the transformation them into the humus horizon. Based on the monitoring studies results it was established that during 21 intensive use years the peat layer thickness was decreased by 74.5% and amounted to 5.51 inch, which in the following 20 years was decreased to a layer of 1.18 inch, and for another 14 years it became a homogeneous humus horizon containing difficulty identifiable plant remains. For half a century, the bulk density increased by 6 times and the total moisture capacity of the soil decreased by 3.6 times. Other indicators were changed significantly. So, the ash content by 2016 increased from 11.2% to 52.7%. It was a reason of the plough-layer decreasing and it mixes with the mineral sand horizon during plowing. It should also be noted that the total nitrogen content in the soil decreased by 1.13%, and total carbon by 15.3% from 1982 to 2016. The dynamics of changes in the soil acidity, phosphorus and potassium content is associated with the introduction of calcareous, organic and mineral fertilizers in the 1980s. The unsystematic exploitation of such soils leads to decrease in the agricultural products productivity and increase in energy costs. When planning these soils usage in agricultural production, it is necessary to develop and implement modern melioration technologies and techniques aimed to increase soil fertility.

The biennial thistle Cirsiumvulgare (Savi) Tenore significantly reduced ponderosa pine (Pinusponderosa Dougl. ex Laws.) seedling growth during the second year of infestation but had insignificant effects in the first year when all thistles were in the rosette stage. Pine stem diameter relative growth rate was significantly negatively correlated with four different indices of thistle interference and with visual estimates of thistle cover. Total thistle density (adults + rosettes) within 2.0 m of target seedlings best explained differences in stem relative growth rate, but density of adults alone and visual estimates of thistle cover were nearly as good. Simple regressions indicated that soil moisture and pine predawn leaf water potential were significantly negatively correlated with thistle density and significantly positively correlated with stem relative growth rate, but multiple regressions and path analyses indicated that their effects on seedling growth were negligible relative to the other (unexplained) effects of thistle density. Foliar nitrogen, phosphorus, and potassium concentrations were not significantly correlated with thistle density and failed to explain differences in seedling growth. Although it remains unclear how thistles suppressed pine seedling growth, if these results hold true at other sites, plantation managers will have at their disposal relatively easy methods for assessing thistle interference.

Granulated organic and mineral fertilizers: Technology and utility properties This work presents the selected aspects of a technological concept for the production of organic and mineral fertilizers from communal sludge stabilized with volatile ash, by using two methods of granulation: coating and pressure. The presented concept is the effect of optimization, taking into account an interference of a number of factors exerted onto the fertilizing values and the mechanical strength of the final products. The fertilizers (contain ash from brown coal) obtained according to that method are characterized by a sufficient (according to law) content of organic matter (35,73% w/w), total nitrogen (1,70% w/w), phosphorus P2 O5 (3,62% w/w) and after the modification, also potassium K2O (8,43% w/w). The mechanical properties are better for the granulates, prepared by using pressure granulation (15,1 kG/cm2) and allow for their transportation, storage and application.

Analysis of modern scientific literature and patents has shown the absence of acid-free production technology of a mechanically activated multicomponent mineral fertilizer containing water-holding substances. Experimental researches connecting with mechanochemical activation and physicochemical properties of Karatau phosphorites prove a possibility of development of a new multicomponent mineral fertilizer. Application of inorganic and organic activators considerably improves qualities of fertilizers because the developed fertilizer mixtures contain nitrogen, phosphorus, potassium, humate and microelements. The suggested technology intends to use wastes of coal mining that leads to presence of humates and microelements in the end product. It was determined, that content of total nitrogen, phosphorus and potassium depends on a form of nitrogen-phosphorus-potassium-containing substances. The given article contains data of researches connecting with use of multicomponent mineral fertilizers in field conditions for cotton cultivation on irrigated light sierozems consisting of soil-forming rocks of loess and loess-type clay loams. The research results show the increase of soil’s fertility and cotton’s productivity. Studying of agronomic efficiency of the new kinds of mechanically activated multicomponent mineral fertilizers at the cultivation of a bean-cereal mixture has been carried out in the Negorelsk experimental nursery-garden of the Belarus State Technical University on a sod-podzol sandy-loam soil and has shown the essential influence on productivity and quality of the bean-cereal mixture. The researches fulfilled on a sod-podzol sandy-loam soil have revealed the essential increase of key indicators of feed productivity. Application of the mineral fertilizers has promoted increase of nitrogen, phosphorus and potassium content in green plants. In so doing content of calcium and magnesium in green mass depends from quantity of the fertilizer used to a smaller extent. An essential difference of crop capacity and feed productivity indicators depending on forms of the applied mineral fertilizers has not been found.

Field experiments were carried out during the dry seasons in (2012-2013 and 2013-2014) to study the impact of Integrated Nutrient Management on some soil properties and nutrients uptake by red onion (Allium cepa L.) in Moda, Michika, Adamawa state, Nigeria. Soil samples were randomly collected and analysed for pH, EC, organic carbon, organic matter, total nitrogen, available phosphorus before and at the completion of the experiment. Total nitrogen, phosphorus and potassium contents of the onion bulbs were determined. There was an improvement in the fertility status of the soil as a consequence of integrated nutrient management. Combined organic and inorganic fertilizer application influenced the uptake of nitrogen, phosphorus and potassium by red onion. The highest nitrogen, phosphorous and potassium uptake by onions of 0.76, 43.82 and 2.42kgha-1 occurred when all treatments were combined. Uptake of N and K increased as treatment level increased. The P uptake was highest at lower treatment levels and could be linked to sufficiency of indigenous soil P for plant growth resulting in high P uptake with minimal addition of nutrient inputs. Integrated Nutrient Management could be adopted to improve soil fertility status and N, P and K uptake by red onions.

The present investigation was carried out to determine soil and leaf nutritional status of some typical healthy and declined mandarin orchards of Amravati District (M.S) during 2016-19.Total twenty five representative surface and depth wise soil and leaf samples from healthy and declined mandarin orchards were collected and analyzed various nutrients in plant as well as leaf samples. The data analysis showed that total nitrogen content in healthy and declined mandarin orchards from surface soils varied from 0.045 to 0.093 % and 0.015 to 0.37% respectively. The available nitrogen, phosphorus and potassium content of healthy orchards surface soils varied from 200.0 to 265.7 kg ha-1 , 22.0 to 35.3 kg ha-1 , 320.0 to 665.0 kg ha-1 and in declined orchards it varied from 130.4 to 203.5 kg ha-1 , 17.8 to 21.3 kg ha-1 , 360.0 to 744.4 kg ha-1 respectively. The exchangeable calcium and magnesium together constitute more than 80% of exchange complex. The exchangeable calcium, magnesium and sulphur content in healthy orchards surface soils varied from 26.34 to 30.22 cmol (p+ ) kg ha-1 , 11.71 to 16.92 cmol (p+ ) kg ha-1 , 0.27 to 0.90 kg ha-1 and in declined orchards it varied from 29.00 to 31.98 cmol (p+ ) kg ha-1 , 12.07 to 13.71 cmol (p+ ) kg ha-1 , 0.36 to 0.69 kg ha-1 respectively. Micronutrients status of orange orchards showed that available copper, zinc, iron and manganese in healthy orchards surface soils varied from 2.20 to 5.60 ppm, 0.50 to 0.79 ppm, 4.50 to 6.29 ppm, 12.61 to 18.11 ppm and in declined orchards it varied from 1.90 to 2.48 ppm, 0.35 to 0.46 ppm, 3.40 to 5.00 ppm, 8.10 to 12.24 ppm respectively. Findings revealed that total nitrogen, available nitrogen, phosphorus, sulphur, zinc and manganese content found more supporting in healthy orchards than declined ones. Depth wise distribution showed that total nitrogen, available nitrogen, phosphorus and copper showed decreasing trend with the soil depth. The leaf nutrient content in the plant showed that nitrogen, phosphorus and potassium content in leaf of healthy orchards varied from 2.35 to 2.55%, 0.14 to 0.17%, 0.82 to 1.00% and in declined orchards it varied from 1.75 to 2.00%, 0.10 to 0.13%, and 0.84 to 1.70% respectively. Calcium, magnesium and sulphur content in healthy orchards varied from 3.00 to 3.90%, 0.60 to 0.74%, 0.21 to 0.19% and in declined orchards it ranged from 2.40 to 3.15%, 0.33 to 0.74%, and 0.19 to 0.23% respectively. Results pertaining to micronutrient showed that iron; manganese, copper and zinc in healthy orchards varied from 105.6 to 140.6 ppm, 21.72 to 34.62 ppm, 29.40 to 35.96 ppm, 30.45 to 39.18 ppm, and in declined orchards it varied from 70.66 to 100.00 ppm, 20.38 to 27.67 ppm, 21.72 to 26.05 ppm, and 17.24 to 25.00 ppm respectively. Results showed that a healthy orchard has significantly higher content of nutrient than declined orchards except potassium content

Reduction Of Costs

Agricultural utilization of yellow waters associated with cassava wastewater is a sustainable technique, since it allows reduction of costs related to acquisition of industrialized fertilizers and minimizes the environmental pollution caused by the inadequate disposal of these effluents. In this context, this study evaluated the macronutrient macronutrient content and growth of cowpea fertigated with yellow water associated with cassava wastewater and NPK as source of nutrients. The experiment was set up in a greenhouse located at Campus I of the Federal University of Campina Grande. The experimental design was completely randomized, composed of five treatments characterized by: fertigation with mineral fertilizers, in the form of NPK; organic fertigation composed of human urine, cassava wastewater, human urine plus cassava wastewater; and organo-mineral fertigation composed of urine, cassava wastewater and mineral phosphorus, with four replicates. At 36 days after sowing, the following parameters were determined: contents of nitrogen, phosphorus, potassium, sulfur and the variables number of leaves, plant height, stem diameter, leaf area, shoot fresh matter and shoot dry matter. The use of yellow waters promotes significant increases for growth and production variables for nitrogen and potassium contents mainly, as well as for growth and production variables. The contents of nitrogen, phosphorus and potassium were higher than the levels considered as adequate for the cowpea crop. The use of human urine and cassava wastewater have potential to meet the needs for the main macronutrients required by cowpea and the irrigation via fertigation with these biofertilizers positively influences the development of cowpea.
