Introduction

Well managed long-term agricultural field experiments (LTEs) and their related datasets of

measurements provide a unique research platform for studies on the sustainability of the soil

resource. This catalogue is an inventory of ongoing LTEs within the Nordic countries, describing

their location, their history, the experimental design and treatments, and the availability of archived

samples, of climatic recordings and of data from previous studies on soil and crop properties. The

catalogue is also available at www.planteinfo.dk/Nordic-LTE.

An overview (Petersen et al., 2008) of the LTEs in this catalogue will be presented at NJF-seminar

no. 407 entitled Long-term field experiments - a unique research platform, held in June 2008 and

organized by a working group appointed by Section I (Soil, Water and Environment) of the Nordic

Association of Agricultural Scientists (NJF) and supported by Norden – The Nordic Council of

Ministers. This catalogue and the accompanying overview report are intended to serve as

background for discussing, qualifying and setting common standards for the entries, and for

identifying research areas and joint projects that could benefit from the research platform, e.g. their

feasibility in relation to the proposed EU Framework Directive for protection of the soil resource.

Methods

A questionnaire was established to identify experiments that might qualify for the inventory of

Nordic long-term soil experiments. In the present context LTEs were considered to be experiments

initiated before 1990. Along with an information letter the questionnaire was distributed within each

Nordic country (Iceland, Norway, Sweden, Finland and Denmark) through national contact persons

plus in the Baltic countries (Estonia, Latvia and Lithuania). The structure of the questionnaire was

deliberately kept simple and included entries that could be completed without consulting a large

number of colleagues and without digging deep into experimental details. We requested the

completed questionnaires to be returned before May 2007. In October 2007 a draft inventory was

distributed to researchers who had submitted entries to provide them with the possibility of

checking their entries. Supplementary information concerning climate and experimental designs

was sampled during November 2007-February 2008.

Results

The catalogue includes 38 experimental plans for ongoing LTEs in Norway (NO), Sweden (SE),

Finland (FI), Estonia (EE) and Denmark (DK) (Figure 1). A unique catalogue number consisting of

the country code and a number has been assigned to each experimental plan (Table 1). A familiar

calling name is used for more widely known experiments.

Figure 1 Sites of ongoing long-term experiments initiated before 1990 in the Nordic and Baltic countries. There may be

more experiments located at the same site.

The web-catalogue available at www.planteinfo.dk/Nordic-LTE is a database from which LTEs

may be selected based on included treatments (Mineral fertilizers, Animal manures, Sewage sludge,

Compost, Lime, Crops, Crop residues, Crop rotation and Soil cultivation), existence of plant and

soil archives and country.

Furthermore the web-catalogue offers maps indicating the experimental sites including climatic

conditions. The climate was recorded manually until establishment of automatic weather stations,

often but not always located nearby the experimental site. The monthly mean temperature and

precipitation (1961-1990 normal) for each experimental site available at the web-catalogue are

obtained from the Danish Meteorological Institute (DMI), Estonian Meteorological and

Hydrological Institute (EMHI), Finnish Meteorological Institute (FMI), Norwegian Institute for

Agricultural and Environmental Research (Bioforsk), Norwegian Meteorological Institute (DNMI)

and Swedish Meteorological and Hydrological Institute (SMHI).

The information in the catalogue has been compiled in the overview report (Petersen et al., 2008).

In the early years, emphasis was on crop responses in terms of harvest yields and economic returns, and on demonstrating to farmers and advisors the beneficial effects of nutrient management in crop production. At that time, a general change in agricultural production towards animal husbandry increased the volume of animal manure available on many farms and an increasing number of pigs and cattle required a larger and more reliable production of forage and grain. From this development emerged a need to establish more precisely the value of animal manure given to various crop rotations. At the same time, there was a growing interest in the use of mineral salts (“artificial manures”) as a source of plant nutrients. Scientists had already recognized the potential of mineral fertilizers but the use of mineral fertilizers in crop production was insignificant and many practical issues remained unsolved. One major concern was the consequences for soil fertility when animal manures were completely substituted by inorganic salts. The traditional farmyard manure rich in bedding material contributed to the maintenance of soil organic matter levels. Although it soon became clear that crops grew well following adequate and balanced additions of mineral fertilizers, their longer-term effects on soil fertility remained of great concern. This concern widened the scope of the experiments, and since 1923 soil has been sampled systematically at 4 to 5 years intervals and analysed for chemical properties, including total-C and total-N. Systematic analyses of crops for nutrient content were not introduced until 1949. Adjustments of the experimental layout have been made in accordance with recommendations presented at the Anniversary Workshop. The two major changes concern the B4-field at the Lermarken site and the Sandmarken site. At the Lermarken site,

the experimental plan of the B4-field was changed in 1996. One main objective was to allow for a comparison of equivalent amounts of nutrients given either in cattle slurry or in cattle farmyard manure plus liquid manure. In 1997, the Sandmarken site was converted into permanent grassland. The nutrient additions were stopped and the site was sown to grass in March 1997. The grass is cut once or twice each year, the cut grass being left on the plots. Soil samples are taken from each of the previous treatments every 4th year.

Other or different sampling intervals (2-5 lines): Yield was recorded yearly the first decade. At this time the experiment had a crop rotation and 4 fields. In 1964 one field was planted with different threes species and taken out of rotation. From 1985 and onwards the three remaining fields have been cropped with spring barley in monoculture (with a few exceptions where one or more of the fields were used for special investigations requiring special crops e.g. fallow, winter barley or lupinus). For several decades there are no recordings of yield. Yield recording for one field was initiated again in the mid 1990'es. Soil have beens sampled every 3-5 years since the 1990 and sporadically before that.

The experiment is interesting due to - Well-established gradients in soil pH, which is detectable to almost 1 meters depth, - Pronounced treatment effects on various soil properties. It is very extreme, acidity of unlimed plots precents growth of the merging barley plants within the first few weeks.

Abstract from most recent publication: Results for 1998-2004 are reported from four long-term (25-28 years) tillage trials, comparing conventional autumn ploughing with reduced tillage, normally spring harrowing only. Plant residues were retained during the period studied. Results with reduced tillage were mostly similar to those seen in earlier trial periods. In Trial 1, mean grain yield was 95% with spring harrowing only versus autumn ploughing, 96% when harrowing in autumn was performed as well and 97% when the soil was ploughed every third year. In Trial 2 positive crop rotation effects were found both with and without ploughing, and reduced tillage gave 5% lower grain yield in this trial also. In Trial 3, tillage system did not affect yields of cereals grown in rotation with potatoes, but reduced tillage gave 12% lower potato yield than ploughing. Little difference in response to N fertilizer was found. In Trial 4, reduced tillage on large-scale (0.7 ha) plots

39

Long Continued Agricultural Soil Experiments: A Nordic Research Platform J. Petersen, L. Mattsson, H. Riley, T. Salo, G. Thorvaldsson & B.T. Christensen Catalogue: NO-1

gave 11% lower grain yields than annual ploughing, partly due to shallow sowing depth. No long-term trend in the yield responses to tillage was discernible in any trial, and between-year variability was similar with both ploughing and reduced tillage. Percentage yields with reduced tillage relative to annual ploughing correlated positively with rainfall in May and with mean air temperature in August. It is concluded that the reduced tillage systems studied are sustainable in terms of productivity, relative to labour, machinery and energy inputs. Likely benefits of such systems include higher levels of organic matter and aggregate stability in surface soil horizons, but a disadvantage is the need for frequent herbicide use to control perennial weeds.

The experimental design was: K1, K3 and K4: Randomized split-plot block design in 4 replicates. K5: Randomized block design in 2 replicates. Trial K1: Main-plot treatments: No stubble cultivation vs. Shallow stubble cultivation (8 cm) (24 x 16 m) Split-plot treatments: No autumn ploughing versus autumn ploughing at 25 cm depth (12 x 16 m) Trial K3: Main-plot treatments: No autumn ploughing versus autumn ploughing at 25 cm depth (24 x 13 m) Split-plot treatments: Various (fertilizer, fungicide etc). At present fungicide use against snow mould in winter wheat is being investigated (12 x 13 m). Trial K4: Main-plot treatments: No autumn ploughing versus autumn ploughing at 25 cm depth (50 x 10 m) Split-plot treatments: Various (fertilizer, rotation etc). At present shallow stubble cultivation (8 cm) is being investigated in monocultures of spring oats and spring wheat (12,5 x 10 m) Trial K5: Main-plot treatments: No autumn ploughing versus autumn ploughing at 25 cm depth (200 x 35 m) This is a large-scale trial with only two true replicates. Harvesting is performed on five randomly distributed subplots (15 m² ) per main plot. There are no split-plot treatments in this trial.

Abstract of key reference article: Factorial combinations of N, P and K fertilizer have been compared with the use of farmyard manure at Møystad since 1922 in a seven-year crop rotation (3 ley, oat, potato, wheat, barley). Until 1982, low inputs of N fertilizer (22 kg ha-1) were used. In 1983, they were brought into line with current farming practice. This paper presents results of three subsequent rotations. Yields without any fertilizer were on average 48% of those with 100 kg N ha-1 in compound fertilizer, whilst those with 20, 40 and 60 Mg ha-1 farmyard manure were 81, 87 and 90%, respectively. Yields with other combinations of N, P and K declined in the order NP, NK, N, PK and K. When NPK fertilizer was used, apparent recoveries of applied fertilizer were close to 50% for N and K, and around 40% for P. Much lower values were found for nutrients applied singly. Balance between N supply and removal was indicated at rates of about 60 kg N fertilizer ha-1 in potatoes, 75 kg ha-1 in cereals and 90 kg ha-1 in leys. A surplus of P was found in all crops at all N levels, and of K in cereals and potatoes. In leys, K balance was achieved with an N supply of 90 kg N ha-1. Nutrient balance was indicated at a little below 20 Mg ha-1 yr-1 farmyard manure. Larger manure applications gave large nutrient surpluses, particularly of N. Soil reaction remained close to neutral with the use of calcium nitrate and manure, but declined with the use of ammonium nitrate. Manure use gave the highest amounts of available P, K and Mg in soil. Similar increases in total inorganic P were found with manure use as with fertilizer use, but amounts of organic P and total K were little affected.

Two trials (E and F) adjacent to each other are laid out as randomised block trials with 4 replicates in each. Treatments are applied to plots of 30 m², of which the central area (ca. 10 m²) is harvested. Tillage is kept to a minimum. No ploughing has been performed since before 1990 at this site.

Yields are reported from four long-term (16-30 years) tillage trials, comparing results since 1998, under relatively wet conditions, with earlier experience. In trial 1, on clay loam, mean grain yield with spring harrowing only, compared to that obtained with autumn ploughing, was 87% over the last ten years, whereas it was 94% for the whole period since 1991. The inclusion of autumn harrowing increased these figures to 94% and 98%, respectively. Over the last six years, spring ploughing gave 5% lower yield than autumn ploughing. Relative yields of unploughed versus ploughed treatments were negatively correlated with summer rainfall. Grain protein was lowest with spring harrowing only. In trial 2, on clay loam, direct drilling has since 1998, as in previous years, given around 10% lower yield than autumn ploughing. Autumn harrowing gave 4% lower yield in winter wheat and 6% higher yield in spring oats, than autumn ploughing, whilst yields of spring turnip rape were not significantly affected by tillage.

Sample archive is available for some years. The experimental treatments have been subject to some changes during the years - fertilizer rates have been increased in accordance with the common trends in agriculture, and also the crop sequences have been adjusted. The design includes the following six-course crop rotations: I Continuous cereal cropping II Cereal crops (three years) and row crops (three years) III Cereal crops (four years) and ley (two years) IV Cereal crops (two years) and ley (four years) All crops were grown every year in two replicates making a total of 48 rotation plots, which were located in six blocks of four plots. Each rotation plot was divided into four subplots, which were subjected to the following fertilization treatments: a. Low rates of NPK in mineral fertilizers (30-40 kg N, 15-25 kg P, and 30-120 kg K/ha) b. Normal rates of NPK in mineral fertilizers (80-120 kg N, 25-35 kg P, and 60-180 kg K/ha) c. FYM (farmyard manure) plus mineral fertilizers to supplement to treatment b d. FYM plus mineral fertilizers to supplement to treatment b plus additional fertilizer for grassland for rotations III and IV. Farmyard manure (60 t/ha) was incorporated in spring by harrowing before planting, once in the 6 years period. After 1980 the manure was applied in the form of slurry. From 1992 all cereal straw has been ploughed in annually.

The experiment consist of three regionally adapted eight-year crop sequences. A "traditional" crop sequences including rotational leys and animal manure is compared with two modern crop sequences adapted to agriculture without cattle. The cattle has largely disappeared from the most fertile soils in Sweden and accumulated in more humid areas with less fertile soils. One of the “modern” crop sequences in the experiment is well balanced to reduce the risk of damages due to diseases and weeds. Crop residues are ploughed under and a one-year ley included to supporty soil fertility. This rotation is quite close to what is used in organic farming without animals. The second modern sequence include a large percentage of the most profitable crops. The crop residues is burned or removed to reduce the carry-over of diseases from one crop to the next. Long-term fertility is not a priority in this rotation. The experiment belonged to the field trial Unit of Crop Sequences (-1992) at the former Department of Crop Production Science with the task to produce experimental data to support increased productivity in Swedish agriculture. No complete report of the experiment has ever been published. The experiment is the last remaining experiment in a series of experiment with locally adapted, but similar, rotations. R4-0007 in the same series is still active, but grown with spring barley in all plots since 2006. The experiment R4-0002 has been maintained and data collected, but has not been used in reports since the closure of the field trial unit in 1992. The experiment do, however, run well. The activities in the experiment has increased in recent years.

The experiment consist of three regionally adapted eight-year crop sequences. A "traditional" crop sequences including rotational leys and animal manure is compared with two modern crop sequences adapted to industrial agriculture without cattle. The cattle has largely disappeared from the most fertile soils in Sweden and accumulated in more humid areas with less fertile soils. One of the “modern” crop sequences in the experiment is well balanced to reduce the risk of damages due to diseases and weeds. Crop residues are ploughed under and a one-year ley included to supporty soil fertility. This rotation is quite close to what is used in organic farming without animals.

The experiment belonged to the field trial Unit of Crop Sequences (-1992) at the former Department of Crop Production Science with the task to produce experimental data to support increased productivity in Swedish agriculture. The experiment has been maintained and data collected since that time. The experiments is designed with crop rotations in main plots and crops in the rotation in sub-plots. Since 1981, each sub-plot has been divided into two N-fertiliser levels. The design gives few degrees of freedom to study treatment effects and are thus best suited to study the interaction between crop and cropping strategy. The residual effects of the systems are studied since 2006. There are twelve plots with barley monoculture in close connection to the experiment

In the trial a sex-year rotation with different annual crops, but without rotational ley, is compared with oats, spring barley and spring wheat grown in monoculture. The straw is either ploughed under or burned in different monoculture treatments. Four levels of nitrogen fertiliser are included. The original aim of the experiment was to find how well different spring cereal crops could manage being grown in monoculture in the short and long-term perspectives.
