SUMMARYField experiments at Askov and Lundgaard Experimental Stations, Denmark, were carried out in 1987–91. Winter and spring applications of pig slurry at two application rates and an unfertilized treatment were combined with three rates of mineral nitrogen fertilizer; 15 treatment in all. Grain and straw yield, nitrogen content and nitrogen uptake of spring barley were measured at harvest. All main effects were significant, resulting in increasing yield and nitrogen uptake both when increasing the rate of mineral nitrogen fertilizer and slurry, and when slurry was applied in spring rather than in winter. The nitrogen content of the barley was affected by mineral nitrogen fertilizer application, and by the rate of slurry. The nitrogen efficiency of applied ammonia-N in the pig slurry was estimated by a quadratic polynomial yield response function and expressed relative to a reference function based on the application of mineral nitrogen fertilizer. The efficiency was estimated at 10 for spring-applied pig slurry. The value for winter-applied pig slurry was lower (0·6) and more variable. The efficiency of ammonia-N in spring-applied pig slurry decreased by 0·4/100 kg N/ha when supplementary mineral nitrogen fertilizer was applied at the same time.

The paper presents the results of the foliar feeding application in the technology of spring barley cultivation for fodder purposes. The effectiveness of foliar nitrogen fertilizer application and treatment with humic fertilizer «Stimulife» is also discussed in the paper. The use of foliar top dressing in a rate of 30 kg N/ha on an unfertilized background contributed to a 28%-increase in the productivity of spring barley. Subsequent treatment of the crop with «Stimulife» resulted in an additional 12%-increase in productivity. Application of a lower nitrogen rate (20 kg N/ha) on the N75P50K50 background contributed to 11%-increase in barley productivity, while with subsequent treatment with «Stimulife» – to 19%. Foliar fertilizer application at a rate of 10 kg/ha on the most fertilized background (N100P75K75) resulted in an increase in barley productivity of 15%, and with subsequent treatment with «Stimulife» – of 30%. The energy yield of the crop and grain chemical composition was estimated. Differences in the experiment treatments resulted in a change in the chemical composition of barley grain. The combined use of foliar nitrogen fertilizer (30 kg N/ha) with «Stimulife» stimulated an increase in the nitrogen content in barley grain of 50%. Reducing the nitrogen rate to 20 kg N/ha led to an increase in nitrogen in the grain of 44%. The minimum rate of nitrogen in top dressing (10 kg N/ha) allowed to increase the nitrogen content in grain by 16%. Thus, foliar differentiated nitrogen fertilization together with «Stimulife» treatment on an increasing background of mineral fertilizers contributed to an increase in the protein content of barley grain from 9 to 17%.

The effectiveness of herbicides in spring barley crops on different nutrition backgrounds was studied in field experiments on dark gray forest soil of medium loamy particle size distribution in the conditions of Volga-Vyatka region. It is revealed that on both backgrounds of fertilizer application the barley formed a maximum yield, when applying the herbicide Bomba. When using this herbicide in making mineral fertilizers N54P54K54 the productivity was 2.71 tons per hectare and a dose N70P70K70 – it was 2.83 tons per hectare. On average for three years, the maximum (11.35%) protein content was appeared in the preparation by Sekator turbo herbicide on the background of fertilizer application of N70P70K70.

In the period of 1983-1985, 18 field experiments with potatoes grown for industrial starch production were set up in the Netherlands to investigate the effects of poultry-slurry application on tuber yield and on soil mineral nitrogen. Slurry was applied in autumn with and without the nitrification inhibitor dicyandiamide (DCD) and in spring without DCD. Control treatments without slurry or DCD were included. Various nitrogen fertilizer rates were applied to all slurry treatments. In autumn, following slurry application without DCD, slurry-derived nitrate moved to the 0.3-0.6 and 0.6-1 m soil layers. Following DCD-application, most of the slurry-derived nitrate remained in the 0-0.3 m soil layer. Maximum yields as estimated from a nitrogen fertilizer response function were slightly increased by the slurry application. Nitrogen supplied from the slurry decreased the amount of fertilizer nitrogen needed for maximum yield. Increasing the amounts of soil mineral nitrogen in June from slurry or applied inorganic nitrogen fertilizer increased residual soil mineral nitrogen at harvest.

The aim of this study is to describe the changes of bioavailable phosphorus content in soil in long-term 18 years field experiments with different fertilizing systems. The field experiments are located at three sites with different soil and climatic conditions in the Czech Republic (Červený Újezd, Humpolec and Prague-Suchdol). Same fertilizing systems and crop rotation (potatoes (maize) – winter wheat – spring barley) are realized at each site with following fertilizing treatments: (1) unfertilized treatment (control), (2) farmyard manure (FYM), (3) and (4) sewage sludge (SS 1 and SS 3), (5) mineral nitrogen (N), (6) mineral nitrogen with straw (N + straw) and (7) mineral nitrogen with phosphorus and potassium (NPK). The long-term fertilizing effect on available P content changes in soil was observed. Bioavailable phosphorus content in soil increased in treatments with organic fertilization after 18 year experiment at all sites. The treatments SS 3 had the highest increase at all sites. The highest bioavailable P content increase compared to control (258 mg/kg) was determined at site Červený Újezd. On the contrary, available phosphorus content decreased at treatments with mineral fertilization and control treatment among all sites. Bioavailable P content decrease in the treatment NPK was observed, although phosphorus was applied. The lowest differences in available P content among all fertilizing treatments were observed at the location Prague-Suchdol.

Yield reductions occur when corn (Zea mays L.) is continuously grown compared to when it is rotated with soybean [Glycine max (L.) Merr.]; primarily due to soil nitrogen availability, corn residue accumulation, and the weather. This study was conducted to determine if a combination of agronomic practices could help overcome these causative factors of the continuous corn yield penalty (CCYP) to obtain increased corn yields. Field experiments conducted during 2014 and 2015 at Champaign, IL, U.S.A. assessed the yield penalty associated with continuous corn verses long-term corn following soybean. Agronomic management was assessed at a standard level receiving only a base rate of nitrogen fertilizer, and compared to an intensive level, which consisted of additional N, P, K, S, Zn, and B fertility at planting, sidedressed nitrogen fertilizer, and a foliar fungicide application. Two levels of plant population (79,000 verses 111,000 plants ha−1) and eight different commercially-available hybrids were evaluated each year. Across all treatments, the CCYP was 1.53 and 2.72 Mg ha−1 in 2014 and 2015, respectively. Intensive agronomic management improved grain yield across rotations (2.17 Mg ha−1 in 2014 and 2.28 Mg ha−1 in 2015), and there was a 40 to 60% greater yield response to intensive management in continuous corn verses the corn-soybean rotation, suggesting intensified management as a method to mitigate the CCYP. With select hybrids, intensive management reduced the CCYP by 30 to 80%. Agronomic management and hybrid selection helped alleviate the CCYP demonstrating continuous corn can be managed for better productivity.

Wheat was grown where nitrogen fertilizer does not usually produce a large increase in grain yield. Urea was applied at sowing at rates from 0-75 kg N per hectare and the crop was sown either after cultivation or without cultivation but with the weed controlled with herbicides-a promising technique for earlier planting. Estimates of weeds and growth, nitrogen content, nitrogen stress, and grain yield of the crop were made at appropriate times. Maximum nitrogen stress occurred during tillering. The response by grain yield to urea was small and could be explained only in part by the relatively low values of nitrogen stress at that time. Where cultivation was replaced by herbicides, nitrogen stress was greater and growth rate, nitrogen uptake and grain yield were lower. Application of 75 kg N/ha at sowing compensated for lack of cultivation during the vegetative stage but did not fully do so for grain yield.

The growth and nitrogen uptake of a maize crop (Zea mays) were studied under furrow irrigation on a red-brown earth soil. Plots receiving 120 kg N/ha as urea at sowing were compared with unfertilized plots and with plots receiving the same amount of nitrogen, as urea or aqua ammonia, added to water during three irrigations: in the first or last 2 h of three 6-h irrigations (at 20 kg N/ha.h), or continuously during three 6-h irrigations (6.7 kg N1ha.h). Dry matter accumulation and nitrogen uptake measurements made 21,36,49,84 and 150 d after emergence all revealed a consistent pattern of results. The same pattern was also evident in grain yield. Urea-fertilized plots gave higher yields (mean of the three application methods = 3.2 t/ha) than ammonia-fertilized plots (1 .8 t/ha). Application early in the irrigation was superior to application throughout irrigation (3 .2 and 2 .5 t/ha, respectively), while plots receiving nitrogen late in the irrigation gave the lowest yield (1 .8 t/ha). There was no significant (P< 0.05) difference between yield from plots receiving urea early in irrigation and that from those receiving urea at sowing. Soil nitrate-nitrogen concentrations below the hills were higher for urea treatments, suggesting greater penetration of the urea solution. In the ammonia treatments, a much higher concentration of ammonium-nitrogen was found immediately under the furrow than under the furrows of urea-fertilized plots, confirming the relatively restricted movement of ammonia into the soil. Ammonia concentration of the irrigation water fell by up to 32% over a 90 m length of furrow. This loss was ascribed to volatilization. Urea was superior to ammonia largely because it minimized mineral nitrogen retention near the soil surface and because it was not susceptible to volatilization losses. Fertilizer application early in the irrigation, during the period of high infiltration, resulted in lower retention of mineral nitrogen close to the furrow surface and away from the root zone. It also reduced the proportion of nutrient solution lost to the drainage system.

SummarySeven field experiments were made on the effect of two harvesting dates on the nitrogen requirements of sugar beet. All were on Rauceby series soils overlying oolitic limestone in Lincolnshire.Nitrogen fertilizer increased sugar yield in all experiments, and yield was considerably higher at the mid-December harvest than in early October. On average, the sugar-yield response to nitrogen was greater at the late harvest, and the requirement for nitrogen was about 45 kg/ha higher then than at the early harvest. Sugar content was depressed less at the late harvest than at the early by increasing nitrogen rate.These results suggest that farmers should apply more nitrogen to fields that they plan to harvest late than to early-harvested fields; they also have implications for the conduct and interpretation of nitrogen response experiments on sugar beet.
