Cross Compliance

The paper presents the main results of the monitoring on the effectiveness of the cross-compliance Standard 4.1 ‘Permanent pasture protection: lett. b, c’ carried out in two case studies within the project MO.NA.CO. Soil, botanical, productive and economic (competitiveness gap) parameters have been monitored. In the short term, the Standard 4.1 showed its effectiveness on soil quality, biomass productivity and competitiveness gap in both case studies. Botanical parameters showed differing results, therefore their generalization is not applicable to the heterogeneity of the pasture land Italian system. Shallow soil tillage could be suggested, every 40-50 years, when an appropriate soil organic matter content and the absence of runoff phenomena occur.

AbstractThe effects of different tillage systems on the properties and microbial diversity of an agricultural soil was investigated. In doing so, soil physical, chemical and biological properties were analysed in 2013-2015, on a long-term field experiment on a loamy sand at the IUNG-PIB Experimental Station in Grabów, Poland. Winter wheat was grown under two tillage treatments: conventional tillage using a mouldboard plough and traditional soil tillage equipment, and reduced tillage based on soil crushing-loosening equipment and a rigid-tine cultivator. Chopped wheat straw was used as a mulch on both treatments. Reduced tillage resulted in increased water content throughout the whole soil profile, in comparison with conventional tillage. Under reduced tillage, the content of readily dispersible clay was also reduced, and, therefore, soil stability was increased in the toplayers, compared with conventional tillage. In addition, the beneficial effects of reduced tillage were reflected in higher soil microbial activity as measured with dehydrogenases and hydrolysis of fluorescein diacetate, compared with conventional tillage. Moreover, the polimerase chain reaction – denaturing gradient gel electrophoresis analysis showed that soil under reduced till-age had greater diversity of microbial communities, compared with conventionally-tilled soil. Finally, reduced tillage increased organic matter content, stability in water and microbial diversity in the top layer of the soil.

Soil structure is a key determinant of many soil environmental processes and is essential for supporting terrestrial ecosystem productivity. Management of arable soils plays a significant role in forming and maintaining their structure. Between 1994 and 2011, we studied the influence of soil tillage and fertilisation regimes on the stability of soil structure of loamy Haplic Luvisol in a replicated long-term field experiment in the Dolná Malanta locality (Slovakia). Soil samples were repeatedly collected from plots exposed to the following treatments: conventional tillage (CT) and minimum tillage (MT) combined with conventional (NPK) and crop residue-enhanced fertilisation (CR+NPK). MT resulted in an increase of critical soil organic matter content (St) by 7% in comparison with CT. Addition of crop residues and NPK fertilisers significantly increased St values (by 7%) in comparison with NPK-only treatments. Soil tillage and fertilisation did not have any significant impact on other parameters of soil structure such as dry sieving mean weight diameters (MWD), mean weight diameter of water-stable aggregates (MWD<sub>WSA</sub>), vulnerability coefficient (Kv), stability index of water-stable aggregates (Sw), index of crusting (Ic), contents of water-stable macro- (WSA<sub>ma</sub>) and micro-aggregates (WSA<sub>mi</sub>). Ic was correlated with organic matter content in all combinations of treatments. Surprisingly, humus quality did not interact with soil management practices to affect soil structure parameters. Higher sums of base cations, CEC and base saturation (Bs) were linked to higher Sw values, however higher values of hydrolytic acidity (Ha) resulted in lower aggregate stability in CT treatments. Higher content of K<sup>+</sup> was responsible for higher values of MWD<sub>WSA </sub>and MWD in CT. In MT, contents of Ca<sup>2+</sup>, Mg<sup>2+ </sup>and Na<sup>+</sup> were significantly correlated with contents of WSA<sub>mi </sub>and WSA<sub>ma</sub>. Higher contents of Na<sup>+</sup> negatively affected St values and positive correlations were detected between Ca<sup>2+</sup>, Mg<sup>2+ </sup>and Na<sup>+</sup> and Ic in NPK treatments.

Maize Response

No-tillage systems, associated to black oat as preceding cover crop, have been increasingly adopted. This has motivated anticipated maize nitrogen fertilization, transferring it from the side-dress system at the stage when plants have five to six expanded leaves to when the preceding cover crop is eliminated or to maize sowing. This study was conducted to evaluate the effects of soil tillage system and timing of N fertilization on maize grain yield and agronomic efficiency of N applied to a soil with high organic matter content. A three-year field experiment was conducted in Lages, state of Santa Catarina, from 1999 onwards. Treatments were set up in a split plot arrangement. Two soil tillage systems were tested in the main plots: conventional tillage (CT) and no-tillage (NT). Six N management systems were assessed in the split-plots: S1 - control, without N application; S2 - all N (100 kg ha-1) applied at oat desiccation; S3 - all N applied at maize sowing; S4 - all N side-dressed when maize had five expanded leaves (V5 growth stage); S5 - 1/3 of N rate applied at maize sowing and 2/3 at V5; S6 - 2/3 of nitrogen rate applied at maize sowing and 1/3 at V5. Maize response to the time and form of splitting N was not affected by the soil tillage system. Grain yield ranged from 6.0 to 11.8 t ha-1. The anticipation of N application (S2 and S3) decreased grain yield in two of three years. In the rainiest early spring season (2000/2001) of the experiment, S4 promoted an yield advantage of 2.2 t ha-1 over S2 and S3. Application of total N rate before or at sowing decreased the number of kernels produced per ear in 2000/2001 and 2001/2002 and the number of ears produced per area in 2001/2002, resulting in reduced grain yield. The agronomic efficiency of applied N (kg grain increase/kg of N applied) ranged from 13.9 to 38.8 and was always higher in the S4 than in the S2 and S3 N systems. Short-term N immobilization did not reduce grain yield when no N was applied before or at maize sowing in a soil with high organic matter content, regardless of the soil tillage system.

Applying alternative soil cultivation methods based on reduced disturbance of the soil more favourable conditions can be created in order to increase the organic matter content of the soil and the availability of the nutrients for the crops. In complex soil tillage experiment – in 1997 was set on – at Karcag, as the element of the investigation of soil reduced and conventional tillage systems. There is close correlation between the degree and intensity of CO2-emission from the soil and the structural state and organic matter content of the soil. In order to quantify the increased CO2-emission from soil due to soil preserving cultivation systems, in situ CO2-emission of soil was measured by means of an ANAGAS 98 infrared gas analyser. The soil type of the investigated plot is meadow chernozem solonetz in the deeper layers, a soil type that is characteristicfor the Trans-Tisza Region of Hungary. In this paper the results gained from the measurement on different stubbles are published, as we consider stubbles the most suitable state when the effects of different soil cultivation systems on the microbiological activity of the soil can be compared. Experimental data provided information about the length of the time period when CO2 emission increasing effects of soil cultivation are observable. Studying the effect of different soil cultivation methods on the CO2 emission from chernozem soil is indisputably actual and needs more efforts as it can contribute to develop a more environmental friendly agricultural production. The main goal of these measurements was to determine the effect of soil cultivation technologies and certain agrotechnical elements on the factors of the soil carbon cycle.

<p>Within the MO.NA.CO. Project<em> </em>the environmental effectiveness of GAEC cross-compliance Standard 3.1 ‘Ploughing in good soil moisture conditions’ was evaluated, as well as the economic evaluation of the competitiveness gap for farmers which conform or do not conform to cross-compliance. The monitoring has been carried out at nine experimental farms with different pedoclimatic characteristics, where some indicators of soil structure degradation have been evaluated, such as bulk density, packing density and surface roughness of the seedbed, and the crop productive and qualitative parameters. In each monitoring farm two experimental plots have been set up: factual with soil tillage at proper water content (tilth), counterfactual with soil tillage at inadequate water content (no tilth). The monitoring did not exhibit univocal results for the different parameters, thus the effectiveness of the Standard 3.1 is ‘contrasting’ (class of merit B), and there was an evident practical problem to till the soil at optimum water content, even in controlled experimental condition. Bulk density was significantly lower in the factual treatment although in soils with very different textures (sandy-loam and clayey). Packing density (PD) showed a high susceptibility to compaction in soils with low PD and medium texture. The tortuosity index, indicating the roughness of the seedbed, was lower and generally significantly different in the factual treatment. Results showed that the ploughing done in excessive soil moisture conditions is more expensive due to the increased force of traction of the tractor, which causes an increase in slip of the tractor wheels, with a speed reduction and increase in the working times and fuel consumption. Moreover, the crop yield is also reduced considerably according to the cultivated species.</p>

In the last decades the physical and biological status of the soils in Hungary significantly decreased. The degree and intensity of CO2-production of the soil is in close correlation to its structural status and organic matter content. In a complex soil tillage experiment at Karcag in situ measurements have been carried out since 2002 in order to determine the CO2-emission of the soil. Carbon-dioxide emission of the soil in the cases of conventional tillage and reduced cultivation system was analysed in a long-term cultivation experiment. The measurements were carried out after the harvest of the barley, thus root respiration was excluded. For the spatial delimitation of the measuring area a newly developed frame+bowl set was used. Based on measurements, significant differences between cultivation systems can be recognized due to the soil structure changes and its effects

It is estimated that around 95 percent of national rice production is supplied from paddy fields, so the paddy fields is very strategic in national food securities. Therefore, the potential carrying capacity and productivity of rice fields must be maintained and developed. But on the contrary the productivity of paddy fields in Sub Das Tampo, Lintau Buo Utara, Tanah Datar District, West Sumatra, there is an indication of a decrease in paddy productivity in the last 10 years (Agita and Ayendra 2018). Decreased paddy productivity is indicated as a result of 1.) Drainage or nutrient deficit due to harvest carried out more than what is given through fertilization or addition of nutrients from irrigation water, 2). Excess or lack of certain nutrients due to unbalanced fertilization, 3). Decreased of soil organic content in the land and 4). Decrease in the quality of rice field management, especially: a). the use of inorganic fertilizers which causes low organic matter content and soil texture becomes porous quench, so it is less able to hold water, b). use of rotary plow in tillage for a long time which causes the processing layer and the depth of the root zone to become shallower ( into 10-15 cm), c). less intense of crop maintenance. This research was carried out by creating of soil tillage from 10-15 cm to 20-25 cm using a plow and increasing of organic matter by adding manure of 50 tons / ha (5% soil tillage zone ) to the rice fields in the Farmers Group of Tanjung Mutiara in Tampo Irrigation System, Nagari Lubuk Jantan , Kecamatan Lintau Buo Utara. The results of the study showed an increase in land productivity from an average of 3.2 tons / ha to 4.6 tons / ha and increase farmers' income by Rp 1.200.000 / ha.Key words : land creation, soil tillage, productivity

The results of the study on the comparative assessment of different tillage methods in the field crop rotation with different levels of mineral nutrition (N30P30 and N60P30 kg of active ingredient/ ha) are presented. The experiment was carried out on low-humus low-carbonate chernozem of the forest-steppe zone of Eastern Trans-Baikal Territory in 2012–2014. The zoned variety of Buryatskaya-79 spring wheat, and Metis oat variety were used for sowing. Low-cost methods of soil tillage were studied, providing for the preservation and improvement of soil fertility, an increase in the productivity of grain and fodder crops, and a decrease in material and energy costs. Replacement of the basic tillage with a PN-4-35 plow with a ring roller in the third and fourth crop rotation fields by surface tillage with a Stepnyak-7.4 cultivator and direct sowing on the stubble with a PPM Ob4-ZT seeder when applying mineral fertilizers at a rate of N60P30 kg of active ingredient/ha had a positive effect on the condition of the soil. The following indicators of soil fertility were achieved: structural coefficient 1.28–1.38, organic matter content 3.15–3.33%, productive moisture content in the 0–50 cm layer 29.2–31.8 mm, the release of carbon dioxide 1.810–1.969 kg per 1 hour, the content of Р2О5 in the 0–20 cm layer 71–96 mg/kg of soil, the content of K2O – 57–82 mg/kg of soil. An increase in the yield of oat grain of 0.16–0.21 t/ha, the green mass of annual grasses of 3.44.0 t/ha, the collection of feed units of 0.32–0.34 t/ha, a reduction in the cost of fuel and lubricants by 31.2-36.4%, and an increase in profitability by 25.0–40.3% were achieved.

Information on the pH buffer capacity of soil is required to estimate changes in pH due to acidic or alkaline inputs, and to model pH-dependent processes within the soil nitrogen (N) cycle. The objective was to determine whether a model based on soil organic matter (SOM) and mineral characteristics (clay content, extractable iron (Fe) and aluminium (Al)) would be adequate to estimate the buffer capacities of New Zealand soils. We measured pH changes in 34 soils, representing a range of SOM and texture, after equilibration with several rates (range 0–15 cmol OH– kg–1 soil) of either KOH or Ca(OH)2. The Ca(OH)2 method often yielded higher buffer capacity values than the KOH method, possibly because of incomplete reaction of Ca(OH)2, especially at high addition rates. Buffer capacity (measured using KOH) of the soils was strongly correlated with soil carbon (C) (R2 = 0.76), and weakly (but significantly, P < 0.05) with clay content, and with dithionite extractable Fe and Al. A regression with soil C, clay, and P-retention (a surrogate for extractable Al and Fe) as independent variables explained 90% of the variability in pH buffering. The role of organic matter was further evaluated by measuring buffer capacity of soil from research plots at Lincoln, Canterbury, New Zealand, that differed in C (21–37 g C kg–1 in the top 7.5 cm; 19–26 g C kg–1 in the 7.5–15 cm) as a result of the treatments imposed during the 12-year trial period. A substantial decrease in pH buffering (by up to 24% in top 7.5 cm) was associated with a decline in SOM following the conversion of permanent pasture (pre-trial land use) to arable cropping. Across all treatments and sampling depths, buffer capacity was linearly related (R2 = 0.84, P < 0.001) to soil C; the estimated buffer capacity of SOM was 89 cmolc kg–1 C pH unit–1, similar to the value calculated from the previous study with different soil types. After 12 years, treatments with low soil C concentrations tended to be more acidic, possibly partly because of weaker pH buffering.

Abstract Conservative systems are based on less intense soil loosening, carried out by different methods, without turning the furrow and only in the conditions of keeping a certain amount of vegetal residues at the soil surface; for that reasons are therefore considered to be ecological protection strategies. For this study the parcel of 118.78 ha was divided into two plots of 59.39 ha each. On the first plot (P1) the conventional soil works system was used, while on the second plot (P2) was used the system of minimum soil works. The methodology used was to analyze, synthesize and calculation of fuel consumption. Following the application of soil conservation systems, many benefits have been identified: - the time with soil tillage is reduced at 2-4 times;-the fuel consumption per unit area is reduced by 40-50%;- the number of agricultural machinery at the surface unit is reduced;-soil structure is rebuilt and surface and depth compaction is reduced;- the organic matter content from the soil is increased;- soil permeability for water is increased and global soil drainage is improved;
