Studies were conducted on an experimental field of Samara State Agrarian University in 20072019 with the purpose of studying the influence of primary soil tillage of typical heavy loam chernozem and aftereffect of different organic fertilizers on the yield of soybeans. The most optimal conditions for the soil density were determined by plowing, which was 0.90-1.10 g / cm3 for the growth and development of soybeans. Primary tillage did not have any significant effect on the productive moisture reserves in the meter layer of soil. Shallow tillage and no-till contributed to a 1.3-time increase in weediness of soybean crops compared to plowing. The greatest crop yield 1.45 t / ha was collected by plowing, which was 0.25 and 0.44 t / ha higher than by shallow tillage and no-till respectively. The aftereffect of organic fertilizers promoted the additional soybean yield of 0.17-0.18 t / ha compared to the non-fertilized plot. New types of organic fertilizers were as good as manure in terms of impact on productivity.

Over a 5 year period, we examined the influence of substrate and fertilization on nursery growth and outplanting performance of Norway spruce (Picea abies (L.) Karst.). We focused on the relative growth and development of roots and shoots and the colonization intensity and diversity of ectomycorrhizal (ECM) fungi. In the nursery, a conventional substrate (low-humified Sphagnum peat) supplemented with woody material (wood fibre and pine bark) and either mineral or organic fertilizers yielded shorter seedlings than those grown on the unmodified substrate. However, after outplanting, the growth rate of seedlings cultivated on modified substrates was higher than that of seedlings grown on the unmodified substrate. Seedlings cultivated in modified substrates had significantly higher root/shoot ratios and ECM diversity; the latter remained significant after ≥3 years of outplanting. Seedlings grown on a substrate containing 50% woody material and supplemented with organic fertilizer had the highest growth rate among all seedlings during the 3 year period of outplanting. Colonization intensity of ECM fungi was high in all seedlings except for those grown in heavily fertilized substrate. This study suggests that nursery techniques that produce seedlings with higher root/shoot ratios and ECM diversities could improve plantation success and growth rate for at least the first 3 years of outplanting.

How do you manage to achieve optimal conditions for growth and development of plants, which can only be achieved through the diversification of soil tillages and and executing their correctness. Moisture and nutritive stress during crop growing, symptoms of nitrogen or phosphorus deficiency are very common in plants grown on compacted land, so production can be significantly reduced.The experiment realized at A.R.D.S. Turda is focused about the influence of the soil cultivation system (conventional and minimum tillage), fertilizer and agricultural year on the soil humidity and yield at maize. In the minimum tillage system the water accumulates in the soil harder but it loses more slowly but comparative with the classic system when accumulates in easier but is lost more quickly. The two years taken into study, 2015 and 2016, were favorable for the realization of corn production so there were yields of over 7000 kg/ha.

A field experiment was conducted to evaluate weed control systems in a conservation tillage rotation of grain sorghum [Sorghum bicolor(L.) Moench.] – cotton (Gossypium hirsutumL.) – wheat (Triticum aestivumL.). Herbicide systems included fall and spring/summer inputs of high and low intensity. Tillage regimes were no-till (NT) and reduced-till (RT) systems; the latter included fall primary tillage followed by spring stale seedbed planting. Both tillage systems utilized controlled traffic lanes and wide, raised beds. Effective johnsongrass [Sorghum halepense(L.) Pers. # SORHA] control required intense herbicide inputs at one or both application periods, i.e., in the fall and/or spring/summer. Grain sorghum and cotton yields for the most intense weed control system, which included high inputs in both the fall and spring/summer, were not superior to systems that included high inputs in only one of the two application periods. Seedling johnsongrass emergence occurred before spring planting in RT (but not in NT) in 2 of 3 yr, and control measures were ineffective. After 3 yr, the predominant weeds were johnsongrass and browntop panicum (Panicum fasciculatumSw. # PANFA).

AbstractNortheastern Thailand relies on agriculture as a major economic activity, and has used high levels of agrochemicals due to low facility, and salty sandy soil. To support soil recovery and sustainable agriculture, local farmers have used organic fertilizers from farmed animal feces. However, knowledge about these animal fecal manures remains minimal restricting their optimal use. Specifically, while bacteria are important for soil and plant growth, an abundance and a diversity of bacterial composition in these animal fecal manures have not been reported to allow selection and adjustment for a more effective organic fertilizer. This study thereby utilized metagenomics combined with 16S rRNA gene quantitative PCR (qPCR) and sequencing to analyze quantitative microbiota profiles in association with nutrients (N, P, K), organic matters, and the other physiochemical properties, of the commonly used earthworm manure and other manures from livestock animals (including breed and feeding diet variations) in the region. Unlike the other manures, the earthworm manure demonstrated more favorable nutrient profiles and physiochemical properties for forming fertile soil. Despite low total microbial biomass, the microbiota were enriched with maximal OTUs and Chao richness, and no plant pathogenic bacteria were found based on the VFDB database. The microbial metabolic potentials supported functions to promote crop growth, such as C, N and P cyclings, xenobiotic degradation, and synthesis of bioactive compounds. Pearson’s correlation analyses indicated that the quantitative microbiota of the earthworm manure were clustered in the same direction as N, and conductivity, salinity, and water content were essential to control the microbiota of animal manures.

Nutritionally unbalanced organic waste can be converted into potential resources for animal and plant farming by culturing black soldier fly (Hermetia illucens) larvae (BSFL) and prepupae (BSFP). BSFL and BSFP are rich sources of protein and lipids, while the leftover excrement called “frass” can be used as an organic fertilizer. Using readily available resources, BSFL were cultured on spent coffee, donut dough or an equal blend for 35 days. Survival, productivity, daily pupation and biochemical composition of BSFL and BSFP were measured along with the nitrogen-phosphorus-potassium values of the frass. Survival was highest in the blend compared (81%) to spent coffee (45%) or dough (24%); however, BSFL and BSFP were significantly longer and heavier from dough. Stage and food significantly influenced the protein, lipid and glycogen content of the BSFL and BSFP, which tended to be higher in the latter. While fatty acids were often significantly higher in BSFL fed spent coffee, the amino acid composition of BSFL was generally higher in dough. Frass from the blend had significantly highest nitrogen content, while potassium and phosphorus were significantly higher and lower from spent coffee, respectively. Although coffee and donut dough were suboptimal substrates for BSFL, a blend of these produced BSFL and frass that were nutritionally comparable to soybean meal and many organic fertilizers, respectively.

Natural nitrogen isotope abundance (δ15N) has been suggested as a potential indicator for discriminating organic vegetables from their conventional counterparts. However, little is known about the δ15N characteristic of cauliflower (Brassica oleracea L. var. botrytis) under organic production and how the application of chemical fertilizers could affect this characteristic. In this study, δ15N characteristics of cauliflower (including the intra-plant δ15N characteristic) and soil under different fertilization treatments were investigated under field conditions. Five treatments were laid out: control, chemical fertilizers (F4M0), organic fertilizer (F0M4), and chemical fertilizer in combination with organic fertilizer at the ratio of 3:1 (F3M1) and 1:3 (F1M3). Results showed that plant δ15N was positively correlated with fertilizer δ15N and plant root/flower was more sensitive to changes of fertilizer δ15N and soil δ15N than leaf/stem. Distribution of δ15N in different plant parts (especially in flower and leaf) was significantly changed when organic fertilizers were partially or totally substituted by chemical fertilizers, suggesting a comparison of flower δ15N and leaf δ15N might be applicable for the organic identification of marketed cauliflowers. Our results provide fundamental data for the soil- and fertilizer-specific crop δ15N database and indicate that the intra-plant δ15N characteristic could be helpful for organic cauliflower identification.

PurposeThis research aims to assess the consumers' intention to purchase organic foods for balanced physical and mental growth. It examines the decision-making process in buying organic products built on the extended Theory of Planned Behaviour (TPB). This study designed a model to show how Bangladeshi consumers wish to purchase organic food.Design/methodology/approachData were collected by means of a formal questionnaire from shoppers in different markets who buy organic and non-organic foods. Statistical analysis is done by applying partial least square-structural equation modelling (PLS-SEM).FindingsFindings refer that among the four antecedents called social norms (SN), personal attitude (ATT), perceived behaviour control (PBC) and health consciousness (HC), three (ATT, PBC and HC) have a significant influence on the intention to consume organic food in Bangladesh. The only cognitive variable called social norm (SN) has no statistically significant impact though it positively relates to the behavioural intention to purchase organic food.Research limitations/implicationsThe fitted model did not consider any moderating or mediating variable though there might be such effects regarding organic food purchase and consumption. The study includes a major portion of the respondents from less than Tk. 20,000 monthly income group, which is a price-sensitive group from Bangladesh perspective. Hence, this price sensitivity might have a slight influence on the results of the study.Practical implicationsThis study includes four variables as the predictors to describe consumers' intention to purchase organic food products in Bangladesh. Among the predictors, health consciousness or awareness is found to be most powerful. Though consciousness is the key, the awareness of Bangladeshi citizen regarding organic food is lower than in other parts of the world. Hence, the research model directs the policymakers to increase awareness through different social campaigns.Social implicationsUnder Vision 2040 of promoting sustainable development, the government of Bangladesh is trying to increase organic food consumption. Production and consumption of organic food will positively impact society since organic fertilizers are environmentally friendly and do not harm society. This research promotes a strategy formulation to ensure the consumption of organic foods for a positive social impact.Originality/valueThis study is a unique research to concentrate on the importance and factors influencing the consumption of organic foods in Bangladesh, a recently graduated developing country. Furthermore, it extended the Theory of Planned Behaviour (TPB) and proposed a new conceptual framework.

This article proposes a systematic engineering for sustainable economic and ecologic development. This system is deemed to be applicable in any country of the world. The system aims to realize five important objectives: water source clearance, energy saving and emission reduction, renewable energy and organic fertilizer production, and ecological agriculture development, all in large scale and at low cost. The main conception of the new system to reach these goals is the replacement of the conventional sewage treatment approach with more efficient and more ecological process – the natural fermentation of the mixture of the urban sewage and agrarian wastes, such that water body clearance, including water de-eutrophication, green algae prevention and siltation dredging will all be accomplished at virtually a zero cost. Along with this process, the system can produce a vast amount of renewable energy and organic fertilizers, consequently ecological agriculture development in large scale can be realized. As a result, this system will greatly reduce the use of chemical fertilizers thus largely reduce the consumption of fossil energy and the related polluting emissions. This system is thus fully a circular economy model through full west-reuse processes, which ultimately will enhance our life quality with healthier food and living environment. The system is flexible and adaptable to be implemented in either small towns or megacities. The implementation and operation of this system will also benefits employment growth. Lastly, in terms of economic feasibility and profitability, millions to billions of dollars of annual revenue can be generated from the running of this system in a country.
