Calcium nitrate and ammonium nitrate limestone (»Oulunsalpietari») were compared as the nitrogen fertilizer for oats in 15 field trials and for barley in one trial. The trials were carried out in summers 1959 and 1960 in various places in Finland. The split plot technique was employed in order to reduce the variation as much as possible. In 1959 the amounts of nitrogen applied as these two fertilizers to the corresponding halves of the plots were 25 and 50 kg/ha. In 1960 also higher applications were used: 75 and 100 kg/ha of N. In three trials these fertilizers were compared both as a surface dressing and worked in. Visual observations suggested about 5—6 weeks after sowing a darker green colour in the stands treated with calcium nitrate as compared with the other half treated with ammonium nitrate limestone. These differences later disappeared. In some trials a higher nitrogen content of the plants from the calcium nitrate stands could be demonstrated during this period. The uptake of nitrogen by plants was regularly followed throughout the growing period. Owing to the large variation, usually, no statistically significant difference between the effect of the fertilizers could be detected. In a few cases the superiority of calcium nitrate could be demonstrated. No differences in the ripening could be found. In most trials there was a fairly regular tendency to higher yields and higher nitrogen content in the grain and straw produced by calcium nitrate. Yet, only in a few cases were the differences statistically significant at the five per cent level. Thus, it was concluded that on the basis of the results of these trials ammonium nitrate limestone and calcium nitrate may be considered practically equal as nitrogen fertilizers for oats. There was no difference in the yields of barley produced by these two fertilizers, but the nitrogen content of grains was significantly lower with ammonium nitrate limestone than with calcium nitrate. This may be worth further study in connection with the production of malting barley.

The distribution of ammonium nitrogen and nitrate nitrogen in the soils of field trials was followed in two growing seasons. In these trials ammonium nitrate limestone and calcium nitrate were, at several rates, applied as surface dressing. It was found that not only the ammonium nitrogen but also the nitrate nitrogen applied to the surface of loam, silt, silt clay, and fine sand clay soils tended to remain in the top inch for a considerable period in the absence of heavy rainfalls or a longer wet period. The plants appeared rapidly to deplete the layers downwards from 1 inch, but even after six and eight weeks from the application of the fertilizers the ammonium nitrogen and nitrate nitrogen contents of the surface inch could be markedly higher in the treated plots than in the untreated ones. In the non-cropped soil, eight weeks after the application of the fertilizers, the mineral nitrogen content of the top inch corresponded to about 60 % of the nitrogen applied. On the basis of these results the working in or placement of nitrogen fertilizers seems to be profitable. Fixation of ammonium nitrogen in unexchangeable forms was observed in some of the trials. This, however, did not significantly impair the value of ammonium nitrate limestone as a nitrogen source in these trials.

Six nitrogen fertilizers (urea, sulfur-coated urea, urea-formaldehyde, ammonium nitrate, ammonium sulfate, and ammonium nitrate) were individually applied, either in fall or in spring, at a rate of 224 kg N/ha and compared for nitrogen retention in the different horizons of a podzol under jack pine. Despite its susceptibility to nitrogen losses through ammonia volatilization, urea was by far, among readily available nitrogen fertilizers, the one whose nitrogen is best retained in soil surface horizons. Retention varied with weather conditions that prevailed immediately after fertilizer application. With the other fertilizers used, nitrogen retention followed this order: ammonium sulfate > ammonium nitrate > calcium nitrate. After four seasons, about 50% of the nitrogen applied as sulfur-coated urea and urea-formaldehyde was still found in its original form. Ammonium sulfate is next to urea among the recommended nitrogen sources for similar jack pine sites, considering that fertilizers with nitrate are prone to leaching and the sulfur-coated urea and urea-formaldehyde used presented problems of nitrogen availability.

Balsam woolly aphids were reared on young grand fir trees maintained in controlled environment or outdoors. Solutions of various nitrogen fertilizers were applied repeatedly to the trees and the effects on aphids and bark amino acids were studied. On trees fertilized with ammonium nitrate or a sequence of compounds, aphid population growth was less than on trees fertilized with urea or potassium ammonium nitrate. On urea-fertilized trees, populations multiplied 16.5 times in five generations, compared with a 5.7-fold increase on unfertilized trees and a 1.4-fold increase on ammonium nitrate-fertilized trees. These differences resulted from effects of these nutrients on aphid life history. Urea promoted aphid establishment and reproduction, whereas ammonium nitrate affected these processes, as well as survival, adversely. The highest establishment and survival rates resulted from potassium ammonium nitrate.These differences may be related to fertilizer-induced changes in the amino acid diet of the aphid. Thin layer electrophoresis and chromatography revealed that urea, ammonium nitrate, and calcium nitrate each increased arginine concentrations in the bark, the highest levels resulting from ammonium nitrate. Traces of phenylalanine and asparagine, found in other treatments, were absent from trees fertilized with ammonium nitrate during June.

The effect of irrigation and fertilizer placement on the accumulation of nitrogen in the aerial parts of spring wheat was studied in the relatively dry summer 1969, on the basis of plant samples collected at various stages of development from a field trial on silty clay soil. In addition to 16 kg/ha of nitrogen in the basal dressing, 120 kg/ha of nitrogen was applied as ammonium nitrate limestone, as urea, or as Ureaform, either on the surface, or in rows at the depth of 8 cm. 60 mm of water was applied by sprinkler irrigation, one half about three, and the other half about four weeks after sprouting. Under the conditions of this trial, spring wheat only slightly responded to Ureaform. No significant difference in the effect of urea and ammonium nitrate limestone could be detected. Placement of these two fertilizers tended to increase both the amount of dry matter and its content of nitrogen; these effects were more significant without irrigation. Though irrigation, usually, markedly increased the total amount of nitrogen in the aerial parts of the plants, this was in the later stages of development due only to higher yields of dry matter, since in July the positive effect of irrigation on the percentage of nitrogen in plant dry matter changed to a negative effect. In the grain yields the apparent recovery of nitrogen in urea or ammonium nitrate limestone was estimated to be only about 30 per cent of the 120 kg N/ha applied as surface dressing. Irrigation increased this recovery to 54 per cent, placement of the fertilizer to 42 per cent, and both placement and irrigation resulted in an apparent recovery of 61 per cent. On the basis of plant samples collected two days before harvest, the apparent recovery of nitrogen in urea or ammonium nitrate limestone by the aerial parts of wheat was estimated to be, on the average, 36 per cent from the surface-dressing, and 60 per cent when the fertilizers were placed. Irrigation increased the apparent recovery in the first case to 76 per cent and in the latter case to 96 per cent. Thus, in the field experiment the uptake of fertilizer nitrogen by spring wheat was markedly increased by irrigation and to a lesser extent by fertilizer placement. Both treatments together are recommended.

A field experiment was conducted to examine the effects of different nitrogen fertilizers in combination with bacterial fertilizer onnutrient uptake of horseradish and plant available nutrients of the soil. Three different N fertilizers, ammonium-nitrate, urea and calciumnitrate(116 kg ha-1 N) in combination with Microbion UNC bacterial fertilizer (2 kg ha-1) were applied as treatments in a randomizedcomplete block design in three replications. In this paper we presented the results of soil measurements. The soil of the experimental areawas chernozem with medium sufficiency level of N and P and poor level of K.Our main results:The amount of 0.01M CaCl2 soluble inorganic nitrogen fractions, NO3--N and NH4+-N and also the quantity of soluble organic-N werealmost the same in the soil. N fertilizers significantly increased all the soluble N fractions. The amount of NO3--N increased to the greatestextent and the increase of organic N was the slightest. We measured the largest CaCl2 soluble NO3- -N and total-N contents in the plotstreated with ammonium-nitrate, the largest NH4+-N in the plots treated with calcium-nitrate and the largest organic-N fraction in plotstreated with urea.Bacterial inoculation also increased both soluble inorganic nitrogen forms and also total-N content of soil compared to the control. Inthe case of combined (artificial and bacterial fertilizer) treatments we measured lower NO3--N, organic-N and total-N compared to thevalues of plots having only nitrogen fertilizer treatments. On the contrary in the plots with combined treatments the CaCl2 soluble NH4+-Ncontent of soil in more cases were higher than that of values with artificial fertilizer treatment.As a function of calcium-nitrate application increased AL-P2O5 and AL-K2O values were measured compared to control. MicrobionUNC supplement of calcium nitrate yielded also increase in AL-P2O5 and AL-K2O values, till then supplement of ammonium-nitrate fertilizeryielded a decrease in these values compared to the control.All nitrogen fertilizers resulted in a significant decrease in AL-Mg content of soil compared to the control. Nevertheless bacterialfertilizer increased AL-Mg values in any cases.

The effectiveness of calcium nitrate (CN) and calcium ammonium nitrate (CAN) as N sources for winter wheat in spring was studied in seven field trials in Southern Finland, in the province of Uusimaa. The experiments were carried out on clay soils in 1986—1989. Nitrogen dressings of 120—150 kg ha-1 were broadcasted either as a single application or split into two applications. The two applications were in most cases 30—40 and 90 —110 kg ha-1. The single or the first split application was given in the beginning of the growing season and the latter application at the end of tillering. The grain yields obtained by a single N application of 140—150 kg ha-1 ranged from 2 610 to 7 550 kg ha-1 and the protein content of grains from 9.4 to 14.5 %. The nitrogen form of the fertilizer had no significant effect on the grain yield and on the protein content of grains. Splitting the nitrogen increased the grain yield by 400 kg ha-1 and the protein content of grains by 0.8 percentage points.

The age of sugarcane exerts a definite influence on the nutrient content of the sugarcane leaf. The effects of age on the leaf-nutrient (N-P-K) content were as follows: 1. There was a decrease in the nitrogen content of the leaf as the cane age increased. 2. The rate of decrease of nitrogen with age was greater for nonirrigated than for irrigated cane, being about 2 1/2 times as large for the former as for the latter during the first 7 months. 3. Leaf nitrogen declined more rapidly in ratoons than in plant crops. 4. There was no significant difference in rate of nitrogen decline for the varieties tested: B. 41227, M. 336, and P. R. 980. 5. The time of year the leaf samples were taken had no significant effect on the rate of leaf-nitrogen decline with the age of cane. 6. There was a marked decrease in leaf phosphorus with age of cane in nonirrigated cane up to 4 months, and no change from 4 to 6 months. 7. Irrigated cane decreased in leaf phosphorus, but not quite so rapidly as nonirrigated cane, a decrease apparent until about 9 months. After this the leaf phosphorus began to increase until a cane age of about 14 months, where it once again began decreasing. 8. Leaf potassium did not decrease with age throughout the whole growing period of the sugarcane. At first there was a decrease in leaf potassium with increasing age; however, there was a definite increase as the cane neared maturity. This increase began at about 5 1/2 months for nonirrigated and 15 months for irrigated cane. 9. A table of suggested correction factors for age of sampling is presented to assist workers engaged in foliar diagnosis of sugarcane.

1. Twenty-one experiments were carried out in various parts of England and Scotland in 1959–61 comparing two or more of the nitrogen sources ammonium sulphate, ammonium nitrate, calcium nitrate and urea, combine-drilled in compound fertilizers for spring barley.2. Ammonium sulphate and ammonium nitrate combine-drilled at rates from 35 to 105 lb./acre of nitrogen checked early growth slightly in some of the experiments, with no important difference between the two sources, which also gave similar grain yields.3. Calcium nitrate and urea combine-drilled at 45 lb./acre of nitrogen had no large effect on early growth, while at 70 and 90 lb./acre both fertilizers seriously delayed brairding and reduced the plant population in many of the experiments, especially in eastern England. They gave lower yields than ammonium sulphate and ammonium nitrate in many of the experiments in which early growth was affected, and gave lower mean yields at all rates of application.4. In eleven of the experiments, broadcast applications of two or more of the four nitrogen fertilizers were compared. All sources gave similar mean yields.5. There was a slightly smaller yield from combine drilling than from broadcasting ammonium sulphate and ammonium nitrate, and a markedly smaller yield from calcium nitrate and urea.

Fall or spring applications of six different nitrogen fertilizers (urea, sulfur-coated urea, urea-formaldehyde, ammonium nitrate, ammonium sulfate, and calcium nitrate) at a rate of 224 kg N/ha in an 18-year-old jack pine stand induced a very rapid increase of nitrogen concentration in current year and 1-year-old needles, as well as in weight of current year needles. In the latter, nitrogen content (concentration × weight) increased more than 100% the 1st year following fertilization in the ammonium sulfate and the ammonium nitrate treatments applied in spring. Response did not last more than 2 years. Foliar analysis of other elements (P, K, Ca, Mg, and Mn) revealed a reduction of P concentration in the needles sampled the first fall after treatment together with a reduction of Ca and Mn in the current foliage of the second and third seasons after treatment. Changes in nitrogen concentration in Kalmiaangustifolia L. and particularly in Solidagopuberula Nutt. were in good correlation with those observed in jack pine needles.

SummaryFour factorial experiments made in 1982 and 1983 tested the effect of 10 t CaCO3/ha, applied either in autumn 1981 or spring 1982, on the response of established grassland to 360 kg N/ha per year applied either as ammonium sulphate, calcium nitrate, urea or a mixture of ammonium nitrate and calcium carbonate.Lime did not increase yield in the short term. It also reduced herbage Mn and, to a lesser extent, herbage N, P and Mg. The mixture of ammonium nitrate and calcium carbonate gave about 0·5 t D.M./ha per year more herbage than did the other forms of N.Lime had no effect on the recovery in the herbage of N from calcium nitrate, but it reduced N recovery from the other three fertilizers in 1982, and from urea also in 1983. Soil pH, which initially ranged from 4·9 to 5·7 at the four sites, was raised by lime to almost 7·0 in the top 5 cm soil. This pH is probably not high enough to cause serious losses due to NH3-volatilization.Application of fertilizer prone to loss from NH3-volatilization is not recommended soon after liming. However, the practice is not likely to cause detectable yield loss in established grassland in Northern Ireland.
