The Impact

Numerous studies by Ukrainian and foreign scientists have shown that one of the limiting factors for obtaining a stable yield of any crop is the reserves of available moisture in the soil, especially in critical periods of plant growth. The article presents the results of research on the impact of three farming systems – industrial (control), ecological and biological and four options for primary soil tillage – plowing by 20–22 cm (control), chiseling by 20–22 cm, disking by 10–12 cm, disking for 6–8 cm on the reserves of productive moisture in the soil for growing spring durum wheat. According to research, it is established that the highest moisture reserves in a meter of soil for the period of sowing wheat was obtained by combining the biological farming system and chisel tillage, which allowed to accumulate in 2018 – 199.1 mm, 2019 – 179.6 and 2020 – 159.9 mm of available moisture in the soil. The use of chisel tillage in combination with industrial and organic farming systems also provides an advantage in all years of observations over plowing combinations and both disking options with these systems. During the growing season, against the background of all studied agricultural systems, use of chiseling and disking provided the highest reserves of available moisture in the soil. However, the best option should be considered a combination of ecological farming system with chiseling by 20–22 cm, which provided for the flowering period in 2018 – 74.0 mm of moisture, 2019 – 93.7 and 2020 – 90.9 mm, and for the harvest period culture, these indicators were, respectively, 61.0, 67.7 and 61.6 mm. The grain yield of spring durum wheat in this variant was significantly the highest in the experiment and was, respectively, 4.6, 6.7 and 5.6 t/ha.

This work presents the results of the study of changes of the potential contamination of soybean agrophytocenosis in grain-row crop rotation by using different systems of farming and typical black soil tillage. It was established that in the upper 0–5 cm layer of soil there are on average 393–671 million pieces of weed seeds. which is 33.6–43.0% of the total number in the layer of soil 0–20 cm. It was established that the use of periodical moldboard and superficial basic soil tillage had no impact on reducing the potential contamination of typical black soil compared to the variant of differentiated tillage. During subsurface plowing the total number of seeds in the soil layer 0–20 cm increased by 13.5–25.8% compared to differentiated tillage. In the variants of ecological and biological farming systems the number of weed seeds in the layer 0–5 cm was 11.3–19.6% higher compared to the intensive farming system. Based on monitoring of the species composition of the weed seeds bank it was established that in the arable layer of the soil the largest share are annual dicotyledonous – 48–62%. annual monocotyledonous – 30.2–44.6%. perennial – 0.9–3.3% of the total number. It was proved that under the intensive system of farming the yield of soybean variety Silesia increased on average from 10.2 to 147% compared to the ecological and biological system of farming. During the biological system of farming soybean yield did not exceed 1.0–1.8 t/ha. Therefore. the industrial and ecological system of farming had the greatest impact on reducing the potential weediness of the soybean agrocenosis during the growing season. During the biological system of farming crop yields decrease due to the accumulation of weed seeds in the topsoil and formation of high actual weediness of the soybean agrocenosis.

The Impact

Farmer field schools (FFSs) emerged in response to the gap left by the worldwide decline in agricultural extension services. With time, this methodology has been adapted to specific rural contexts to solve problems related to the sustainability of peasant-farming systems. In this study we draw upon empirical data regarding the peasant-farming system in the Nicaraguan highlands to evaluate whether FFSs have helped communities improve the sustainability of their systems and the food security of their residents using socioeconomic, environmental, and food and nutrition security (FNS) indicators. In order to appreciate the long-term impact, we studied three communities where FFSs were implemented eight, five, and three years ago, respectively, and we included participants and nonparticipants from each community. We found that FFSs have a gradual impact, as there are significant differences between participants and nonparticipants, and it is the community that first implemented FFSs that scores highest. The impact of FFSs is broad and long lasting for indicators related to participation, access to basic services, and conservation of natural resources. Finally, this paper provides evidence that FFSs have the potential to empower farmers; however, more attention needs to be paid to critical indicators like production costs and the use of external inputs in order to scale up their potential in the future.

The Impact

The paper proposes a method for determining specific soil resistance and presents the results of the conducted research. One of the main limiting factors in determining the working width of the tillage implement is specific soil resistance. This indicator is a quantitative characteristic of the labor intensity of soil tillage. Therefore, when designing new machinery, it is necessary to have reliable data on its value. The data presented in the scientific literature on the value of specific soil resistance are average and do not take into account the parameters of tillage working tools. Therefore, the determination of specific soil resistance for working tools with known parameters is the current topic of scientific research. The purpose of the research is to determine the value of specific soil re-sistance for working tools with known parameters. The research method consists of the experimental determination of the total draft resistance of the tillage implement and further mathematical processing of the obtained experimental data on the basis of the rational formula of Vasily P. Goryachkin. To conduct experimental research, a laboratory unit was developed. Its design elimi-nates the impact of its weight on the draft resistance, arising from the friction between the parts of the working tool and soil. It was found that for the soils under consideration, which are typical for Northern Kazakhstan, the specific soil resistance is k = 45908 N/m2. The obtained coefficient of variation υ < 10 % indicates a slight change in the considered variation. Therefore, the obtained value of the specific soil resistance is reliable. The obtained results will be used to substantiate the working width of the tillage implement with the working tools under consideration.

The Impact

Agricultural intensification may cause significant changes in weed density due to high weed competitiveness. Therefore, sustainable practices are to be designed to get maximum benefits of plant biodiversity in the agro-ecosystems. Field experiments were conducted in 2013/2014 and 2014/2015 to evaluate the impact of fertilizer source and soil tillage on weed spectrum in durum wheat (Triticum durum Desf.). Treatments in this study were: (i) two fertilizer sources (mineral fertilizer (MIN) and municipal organic waste (MOW)), and (ii) three tillage regimes (plowing (Plo), subsoiling (Sub) and spading (SM)). A randomized complete block design with three replications was adopted. Data on weed density and biomass were collected at the wheat tillering stage. Weed density was higher in MOW than MIN (53.8 vs. 44.0 plants·m−2), especially in 2014/2015, while S was the highest among tillage regimes (58.2 plants·m−2). Annual and monocots species were always the highest in subsoiling (43.5 and 10.1 plants·m−2). The density of perennial and dicots species was higher in MOW compared with MIN plots, regardless of soil tillage management. Weed community, in terms of weed species composition, varied between the two fertilizer sources, while among soil tillage regimes, it only differed between plowing and subsoiling. Based on the analysis of weed community composition, annual dicot species were mainly associated with plowing, while monocots tended to be associated with MIN fertilizer. Spading tillage may be a useful strategy for managing weed diversity under organic fertilization, where mineral soil nitrogen availability was limited. Conversely, the spading machine produced lower grain yields than plowing with mineral fertilizer application.

The Impact

In cereal-livestock farming systems of North Africa and West Asia the straw of durum wheat [Triticum turgidum (L.) Thell. ssp. turgidum conv. durum (Desf.) MacKey] is frequently used for feeding animals during the dry season and may enhance the sustainability and the flexibility of farming in various respects. In Algeria the average sale price per unit weight of the durum straw is around 30% of that of grain. Six tall and 18 semi-dwarf locally well-adapted cultivars were grown in the season 2000/01 at five Algerian locations representing the main durum wheat cropping areas to verify: (i) the impact of straw yield on the economic merit of cultivars for recommendation and (ii) the interest of tall v. semi-dwarf plant types for breeding. The tall material comprised four cultivars derived from local landraces and two old varieties. The semi-dwarf germplasm originated from CIMMYT, ICARDA or various Mediterranean countries. In the economic assessment the straw value was expressed in terms of grain-equivalent, defining an economic yield as: grain yield+(0·30×straw yield). The merit of individual cultivars was markedly affected by ignoring or taking into account the straw yield. On average, tall germplasm had a moderate (about 3%) but significant (P<0·02) economic advantage over semi-dwarf material as a result of much higher straw yield (+25%) and aerial biomass (+12%) and somewhat lower grain yield (−7%). However, three semi-dwarf varieties from CIMMYT were top-ranking for economic yield. They possessed outstanding aerial biomass and similar harvest index compared with the mean response of other semi-dwarf germplasm. On average, the tall germplasm showed higher grain yield stability (P<0·01), lower straw yield stability (P<0·01) and slightly higher stability of economic yield (P<0·11) than the semi-dwarf group as measured by Shukla's stability variance. Grain yield was negatively correlated with straw yield (r=−0·41, P<0·05), and was not correlated with aerial biomass, in the whole set of cultivars. However, it was not correlated with straw yield, and was positively correlated with aerial biomass (r=0·61, P<0·01), within the semi-dwarf germplasm. Information on straw yield can improve the targeting of cultivars for cereal-livestock farming systems. Breeding for these systems may target either a tall type within semi-dwarf material (i.e. a ‘tall dwarf’), or a truly tall plant type.

The Impact

Microorganisms are the most important bioindicators of the environment and ecological risk assessment. The impact of the no-till farming system in combination with microbial preparations needs to be studied and is an urgent task aimed at preserving fertility. The aim of our study was to determine the effect of pre-sowing inoculation with complex microbial preparations (CMP) and farming systems (no-till and conventional farming system) on the microbocenosis of the rhizosphere of Triticum aestivum L. in the Crimean Steppe. Microbiological analysis of the rhizosphere showed a significant increase in the number of actinobacteria (twice). The number of micromycetes, among which there are many pathogens of various plant diseases, decreased under direct sowing by 23 % as a result of inoculation and amounted to 21.5 thousand CFU/g of soil. The number of cellulose-destroying microorganisms that form soil fertility increased under the influence of microbial preparations by 23 % under conventional farming system (10.0 thousand CFU/g of soil); by 20 % under no-till (15.4 thousand CFU/g of soil). Thus, it was found that the use of microbial preparations under both farming techniques contributed to an increase in the number of microorganisms of most ecological-trophic groups that participate in the transformation of nitrogen in the rhizosphere, enhanced enzymatic processes, reduced the development of pathogenic microbiota and, consequently, contributed to improving the state of soil biocenosis.

Sum Of Active Temperatures

Soybean has an ecological adaptability due to the deep selectivity of this crop in relation to the specific features of the growing zone. At the same time, it makes increased demands on heat and moisture, especially during certain "critical" periods of growth and development. The lower threshold of active average daily temperatures is 15–17oC, and for full maturation of ultra-ripe and early-maturing varieties, the sum of active temperatures of 1700–2100oС is required. Assessment of the agro-climatic resources of the Ryazan region indicates the possibility of growing precocious soybean varieties here. The limiting indicator in some critical periods may be insufficient moisture. As a result of the conducted research, it was found that soybean varieties of the Northern ecotype are able to form a stable yield in the conditions of the Ryazan region. At the same time, the lesser response to changes in agroclimatic conditions was shown by the Kasatka variety, which showed the shortest growing season and yield at the level of 1.00 t / ha. The Georgiya variety reacted more than any other to changes in weather conditions, its yield was from 1.24 to 1.72 t/ha over the years of research.

The Impact

Greenhouse gas (GHG) emissions from dairy farms are significant contributors to global warming. However, much of the published work on GHG reduction is focused on either methane (CH4) or nitrous oxide (N2O), with few, if any, considering the interactions that changes to farming systems can have on both gases. This paper takes the raw data from a year of activity on a 300-cow commercial dairy farm in Northern Ireland to more accurately quantify GHG sources by use of a simple predictive model based on IPCC methodology. Differing herd management policies are examined together with the impact of integrating anaerobic digestion (AD) into each farming system. Whilst significant success can be predicted in capturing CH4 and carbon dioxide (CO2) as biogas and preventing N2O emissions, gains made can be lost in a subsequent process, negating some or all of the advantage. The process of extracting value from the captured resource is discussed in light of current farm parameters together with indications of other potential revenue streams. However, this study has concluded that despite the significant potential for GHG reduction, there is little incentive for widespread adoption of manure-based farm-scale AD in the UK at this time.

Tillage Methods

The agricultural sector is required to produce food at the same pace as population growth, while accounting for pollution and costs. For this reason, conservative agricultural practices have been employed worldwide. Attenuated Total Reflectance–Fourier Transform Infrared (ATR-FTIR) spectroscopy has the ability to provide a snapshot of the macromolecular composition of a sample in a timely and cost-effective way and it has been widely applied in the field of agriculture to assess food quality. The aim of this study was to exploit ATR-FTIR spectroscopy to assess the impact of different soil tillage methods (conventional tillage, CT; minimum tillage, MT, and no tillage, NT) and nitrogen fertilization levels (0, 90 and 180 kg N ha−1) on the macromolecular composition of leaves and caryopses of durum wheat (Triticum turgidum subsp. durum). The analysis of the spectral data revealed that the quality of durum wheat, in terms of protein content, grown on soil with no tillage was not reduced. Indeed, with regards to caryopses, the different tillage methods influenced only the lipid and hemicellulose content, whereas the macromolecular composition of leaves was sensitive to tillage methods mostly during the early stage of growth. Moreover, no relevant effects were found in leaves and caryopses when different fertilizer concentrations were used. These results provide important knowledge supporting the adoption of both no-tillage soil treatments and reduced fertilization dosage for the development of durum wheat management strategies and support the use of spectroscopy for conservative agriculture practices.

Direct Sowing

The variability of morphometric indicators of typical chernozems is considered based on long-term field experiment in a grain 4-field crop rotation (winter wheat, corn, barley, peas) to assess the impact of plowing as a traditional farming system that uses soil treatment and no-till, in which plowing is not used. On the example of four experimental fields (each with an area of 2.4 hectares), the variation of indicators associated with the features of the soil cover structure and the applied farming systems was revealed. The tillage leads to an increase in the thickness of the soil profile leached from carbonates, and direct sowing leads to its decrease. The highest variability degree is found in the boiling depth of soil. It is shown that the tillage leads to the homogenization of the soils surface layer and the transformation of the soil cover structure, as a kind of ”insurance system " against weather risks reducing its effectiveness. The direct sowing usage leads to the restoration of degraded properties and natural of soils heterogeneity in the soil cover structures, which can be considered as a process aimed at ecological improvement of both specifiс soil sites and the soil cover structures. The mutual influence of the soil cover structure and agricultural systems can be traced in time and space. The soil structure and the cultivated crops yield related to the sustainability of agrosystems to adverse climatic conditions and other risk. For these it is necessary monitoring soil as the basis for the qualitative assessment of soil and selection of the most optimal directions of agriculture development, a new technologies development in the production of agricultural products.
