Evaluating of phosphorus quantity/intensity parameters in soil with different systems of organic fertilizing

One of the refinement methods for estimating the parameters of phosphorus dynamics in soil is the construction of sorption isotherms in dependence on changes of exchangeable sorbed phosphorus in soil (ΔQ) and changes of phosphorus amount in soil solution (ΔI). Regression analysis allows to calculate equilibrium concentration (cequ) and phosphorus buffering capacity (BC). The mentioned analyses were realised on soils from the long-term field experiments of the Czech University of Life Sciences (CULS) in Prague and Crop Research Institute (CRI) in Ruzyně, Czech Republic. The influence of different organic fertilisers compared to the control (not amended) treatment was tested. For the evaluating of parameters, the root and logarithmic functions were used. The lowest cequ of the logarithmic function was always found on not amended treatment. Low amounts were found in the treatments amended with barley straw as well. The highest amounts were found in soil after potatoes cropping fertilised with farmyard manure (FYM). In the FYM variant fertilised with 70 kg P/ha, the cequ value reached 0.45 mg P/l. Both treatments fertilised with sewage sludge (720 kg P/ha and 240 kg P/ha) showed similar values of about 0.25 mg P/l. A different trend was found for the phosphorus buffering capacity (BC); this was the highest at the control treatment and at the treatment fertilised with straw. The lowest BC was observed in both soils after potatoes fertilised with FYM, where it reached 61 mg P/kg and 65 mg P/kg, respectively. Similar trends were found when evaluating root function.

Abstract Soil is the fundamental element in agriculture and is affected in a variety of ways. Besides other things, the long-term application of mineral and organic fertilisers can significantly influence the topsoil pool of nutrients, organic carbon content and pH. Within the scope of longterm field experiments in Praha-Ruzyně, we evaluated the effect of six fertiliser treatments - unfertilised Control, farmyard manure (FYM), cattle slurry (CAT), cattle slurry amended with straw from previous cereals (CAT+STR), mineral fertiliser (NPK) and NPK amended with FYM (NPK+FYM) on a topsoil pool of nutrient content, organic carbon content (Cox) and pH between the years 2001 and 2012. In the selected period, the fertiliser treatment did not influence the N and Cox content (ranging from 0.126% to 0.143%). Phosphorus and potassium were significantly higher in the NPK+FYM treatment (109.82 and 279.27 mg/kg, respectively), while calcium and magnesium were significantly lower in the NPK treatment (2,973 and 134.95 mg/kg, respectively). Application of mineral fertilisers significantly decreased the value of pH, influencing the Ca and Mg topsoil concentrations. Organic fertilisers cannot provide a sustainable amount of nutrients to generate high yields in a short time, but release their nutrients slowly and the range of nutrients is wider. Mineral fertilisers, if not amended with organic fertilisers, can provide huge doses of nutrients, which can be quickly reused for high yields, but negatively influence the pH value, resulting in a decrease in the pool of Ca and Mg.

Technological Methods

In the years 2011–2014, winter wheat grain yield, qualitative and economic parameters were evaluated according to different fertiliser treatments: (1) control: unfertilised treatment; (2) farmyard manure (FYM) and (3) FYM + NPK (farmyard manure applied together with mineral NPK). The highest yields (8.10 t/ha) were recorded in the FYM + NPK treatment, while significantly lower yields (6.20 t/ha and 5.73 t/ha) were recorded in FYM and control treatments, respectively. Similarly, statistically significantly higher values of the quality parameters were found in the FYM + NPK treatment (13.55% of crude protein content and 43.56 mL of Zeleny’s sedimentation test), compared to control (10% and 22.44 mL, respectively). The modelling expert system (AGROTEKIS-Crop Technology and Economy) was used for the evaluation of economy. This software is based on technological methods of cultivation and norms of material input costs and costs of individual mechanised works. The economic benefits and profitability were evaluated for three different levels of grain market price. The highest gross profit per ha was recorded in the FYM + NPK treatment. According to the gross profit, the control treatment provided better results than the FYM treatment.

SummarySix field experiments, three each during 1982–3 and 1983–4, were conducted on a sandy loam soil to study the effect of varying levels of nitrogen, phosphorus and potassium, in the absence and presence of farmyard manure (FYM) (30 t/ha), on the number of tubers and yield of potato in three grades. Increase in nitrogen, phosphorus and potassium application, in the absence or presence of FYM, did not significantly affect the total number of tubers/m2 but did affect the number of tubers in different grades. An increase in nitrogen and potassium significantly decreased the number of tubers/m2 in small (< 25 g) and increased in medium (25–75 g) and large (> 75 g) grades at 45, 60, 75 and 90 days after planting. Increase in the application of phosphorus increased the number of tubers/m2 in the small grade and decreased it in the large grade but did not affect the number in the medium grade. Increase in nitrogen and potassium application decreased the tuber yield in the small grade and increased it in the medium and large grades. Applied phosphorus increased the yield in the small and medium grades and decreased it in the large grade. The increase in the yield of tubers with increase in nitrogen and potassium application was found to be caused by an increase in the number of tubers in the medium and large grades at the expense of the small grade; however, with applied phosphorus the increase in yield was due to increase in the weight of individual tubers within the small and medium grades. FYM application decreased the number of tubers in the small grade and increased it in the medium and large grades. The response of potato to nitrogen increased and to phosphorus and potassium decreased with the application of FYM.

Residual Fertilizer N

Preliminary determinations for NO3- and NH4-N in topsoil from nitrogen field experiments are discussed. The amounts of residual nitrogen as well as the dates and depth for sampling are considerd in order to investigate the need of fertilizer-N for continuous sugar beet. Tops ploughed down as manure increased the available soil nitrogen by about 50 kg/ha. In practice nitrogen from fertilizer and farmyard manure given to previous beet crops seems to accumulate in the beet soils of Finland. The concentrations of nitrate and ammonium nitrogen in topsoil were low in the spring of 1972 and 1973. NO3-N increased in topsoil during the early summer, and the highest concentrations were found at the beginning of July. Starting from the middle of July the amount of NH4-N began to increase both in topsoil and in subsoil. With increasing amounts of nitrogen in the topsoil the sugar content decreases continuously. Also the α-amio N content of beets correlates with the soil nitrogen. There is experimental evidence that 150 180 kg/ha nitrate nitrogen in topsoil (residual + fertilizer N) in early July gives the best economic result. The effects of fertilizer and accumulated soil nitrogen on the sugar beet quality together with som other experimental data have been statistically analysed. Regression coefficients indicated that both forms of nitrogen affected the suger content, the α-amino N concentration and clear juice purity, in a similar way.

Abstract A new glass fertilizer (GF) system of main composition 60P2O5.30K2O.3.5ZnO. 3.5MnO.3Fe2O3 was developed in response to the needs of pea plants with bio-fertilizers (Rhizobium leguminosarum. Bv.vicieae, Bacillus megaterium var phosphaticum, Bacillus circulans).GF was prepared by the traditional melt quenching technique at 1150°C. Characterization of prepared system was done using FTIR spectra before and after immersion in a simulated actual agriculture medium like 2% citric acid and distilled water. During two winter seasons, two successful field experiments were conducted at Cairo University's Eastern Farm to determine the impact of chemical, glass, and bio-fertilizers on plant growth, yield attributes, and seed quality of pea plant. Control treatment were without any addition of recommended chemical fertilizers and other treatments were full dose of recommended chemical fertilizers (100%RDF), glass fertilizers at rate 60 kg fed− 1, Glass fertilizers at rate30 kg fed− 1, 50% RDF ,100%RDF + bio-fertilizers, Glass fertilizers at rate 60 kg fed− 1 + bio-fertilizers, glass fertilizers at rate 30 kg fed− 1+ bio-fertilizers, 50%RDF + bio-fertilizers. Plots received 60 kg fed− 1 glass fertilizers + bio-fertilizers show the highest significant increment in plant growth, number and weight of pods plant− 1, number of grain pods− 1, grain yield, biological yield, P%, k% in pea leaves and quality of pea seeds compared with plots without any addition (control) in both seasons.

In field experiments in the conditions of sod-podzolic sandy loam soils of the Moscow region, protectants were tested. Before planting potatoes, tubers were treated with a new two-component insectofungicide AVG – 0190 (Idikum, SC, iprodion, 133 g/l + Imidacloprid, 100 g/l + diphenoconazole, 6.7 g/l)-1.0 – 1.5 l/t and a mixture of the fungicide Syncler, SC (75 g/l fludioxonyl) and the insecticide Tabu Super, SC (Imidacloprid, 400 g/l and fipronil, 100 g/l)-0.2-0.3 l/t. According to the results of three-year tests, it was found that the etching of potato tubers before planting does not have a negative impact on the germination and biometric indicators of growth and development of potatoes. Their use helped to reduce the development and spread of rhizoctoniosis and provided almost complete protection of potatoes from the first generation of the Colorado beetle – during the mass appearance of older larvae and during the beginning of the departure of larvae for pupation. Biological efficacy against Rhizoctonia amounted to 58.8-66,3%, the Colorado potato beetle – 93,7 95.5 per cent. The use of new potato tuber protectants allowed to increase the gross yield by 6.2-7.1 t / ha or 30.9-35.3% compared to the control. Treatment of seed tubers with protectants helped to obtain a crop free from rhizoctoniosis and increase the yield of standard healthy potatoes by 57.7

Vertical uplift of seedlings and rods on the soil surface and at a depth of 5 cm, and of reference trees, was monitored using a theodolite from autumn to spring in two adjacent field experiments on a silt soil in northern Sweden. Treatments involving scarification (control and square patches of 0.1, 0.2, 0.4, and 0.8 m at natural snow cover) and snow cover (simulated maximum cover, snow free, and natural cover for control and 0.4-m patches) were compared. For snow free and natural snow cover, diurnal variation of soil surface temperature, duration and magnitude of freezing temperatures, and uplift increased with patch size. At the end of the winter under natural snow cover, uplift of the soil surface and shallow soil was between 4.4 and 5.3 cm for the control treatment without scarification and the 0.1-m patch while the uplift for the 0.4- and 0.8-m patches reached 7.611.5 cm. The highest uplift value, 14.6 cm, was observed for the snow-free treatment with 0.4-m patches. Maximum uplift of trees averaged 4.4 cm, which was similar to values observed for seedlings and rods with an intact humus layer and a natural snow cover, indicating that the highest observed uplift was mainly due to needle and soil surface ice. In conclusion, size of the scarified area and duration and thickness of snow cover largely influence frost heaving of tree seedlings in a susceptible soil.

Western Kenya

Soybean is an important crop with nutrition, economic and soil fertility improvement benefits to farmers. However, its production in western Kenya is partly constrained by low soil pH and soil fertility levels. A greenhouse pot study was conducted to evaluate the effects of inorganic fertilizers, farmyard manure and lime application on soil pH, nutrient uptake, growth and nodulation of soybean grown in acidic soils from western Kenya. The experiment was set up in a randomized complete block design with eight treatments: control; NPK; manure; lime; manure+lime; NPK+manure; NPK+lime and manure+lime+NPK. Significant effects of inorganic fertilizers, manure and lime applications were observed on all the variables. Manure, lime and manure+lime treatments increased soil pH by 1.33, 2.19 and 2.28, respectively, above the control treatment. The shoot N was lower under control (1.71-1.81%), NPK (1.85-1.98%) and manure (2.00-2.11%) than under all other treatments. Treatments NPK+lime and manure+lime+NPK recorded higher uptake of P and K nutrients than all other treatments. The control and NPK treatments recorded shorter plants and low leaf area and above-ground biomass compared to other treatments. The NPK+lime and manure+lime+NPK treatments recorded higher plant height and aboveground biomass than other treatments. Lime+manure treatment recorded highest nodule numbers and dry weights per plant. Positive relationships were observed between pH and N, P and K nutrient uptake (R2 ranged between 0.30 and 0.77) and between biomass and N, P and K nutrient uptake (R2 ranged between 0.68 and 0.99). From this study, use of manure and lime could result in improved soil pH for better uptake of nutrients, nodule formation and productivity of soybean in Western Kenya.

Soil compaction caused by mechanical force affects the vegetative and generative plant growth. Field experiments were conducted to study the effects of soil compaction treatments and soil contact pressures on bulk density, penetration resistance and silage maize emergence in a clay-loam soil. Soil compaction treatments were applied while planting as follows: Compaction on furrow surface (F-surface), compaction on furrow bottom (F-bottom), compaction on inter row (I-row), and non-extra compaction as a control (C). The soil contact pressures of 0.025, 0.051 and 0.076 MPa were applied while the control was 0.0085 MPa. Significant differences between soil compaction treatments and contact pressures were recorded in bulk density, penetration resistance and silage maize emergence. Percentage of emerged seedlings increased as the soil contact pressure was increased slightly. The lowest mean percentage of emerged seedlings (52.63%) was obtained with 0.076 MPa contact pressure in F-surface treatment and the highest mean value (81.58%) was obtained with 0.025 MPa contact pressure in F-bottom compaction treatment. The control treatment gave the 69% mean value under the non-irrigated condition.
