The Impact

В условиях Республики Коми в полевом стационарном опыте на дерново-подзолистой легкосуглинистой почве изучена эффективность различных доз органических и минеральных удобрений, а также совместного их применения. Исследования проводили в 1978–2019 годах на опытных полях Института агробиотехнологий ФИЦ Коми НЦ УрО РАН. Целью проводимых исследований было изучение влияния комплексного применения удобрений на продуктивность и качество кормовых культур в шестипольном севообороте. Кормовой севооборот имел следующее чередование культур: картофель, викоовсяная смесь с подсевом многолетних трав, многолетние травы 1 г.п., многолетние травы 2 г.п., викоовсяная смесь, картофель. В результате научных исследований (более 40 лет) установлено, что наиболее эффективной была органоминеральная система удобрений, особенно при внесении 80 т/га торфонавозного компоста (ТНК) и минеральных удобрений. Многолетние исследования показали, что наиболее значительные урожаи кормовых культур (в среднем за три ротации) получены при использовании 80 т/га ТНК и NPK: однолетних трав — 4,4 т/га; многолетних трав — 6,2 и картофеля — 7,1 т/га сухого вещества высокого качества. Содержание сухого вещества в клубнях картофеля в вариантах с NPK составило 18,0–18,8%, на органическом фоне — 18,4–18,9 и при комплексном применении удобрений — 17,1–17,7; в контроле — 19,6%. Количество крахмала в картофеле незначительно различалось по вариантам опыта и равнялось 12,6–13,1%. Содержание нитратов не превышало ПДК (250 мг/кг сырой массы). Количество сухого вещества в однолетних и многолетних травах изменялось незначительно и составляло 19,0–19,8 и 25,0–26,8% соответственно. Установлено, что удобрения способствовали повышению содержания сырого протеина в однолетних и многолетних травах до 13,1–15,0% (в контроле — 11,2%) и 8,8–10,6 % (в контроле — 8,1%) соответственно. The impact of various rates of organic and mineral fertilizers was analyzed in the Komi Republic on sod-podzolic soil with low loam content. The research took place at the Institute of Agricultural Biotechnology in 1978–2019. The goal was to test forage crop productivity and quality under fertilization and six-field crop rotation. Crop rotation happened as follows: potatoes, vetch-oat mixture overseeded by perennial grasses, first-year perennial grasses, second-year perennial grasses, vetch-oat mixture, potatoes. For 40 years the combination of mineral and organic fertilizers was the most effective. The highest yields for three rotations were observed under the application of 80 t ha-1 of peat-manure compost and NPK: annual grasses produced 4.4 t ha-1; perennial grasses — 6.2, and potatoes — 7.1 t ha-1 of high-quality dry matter (DM). Potato tubers accumulated 18.0–18.8% of DM under NPK application, 18.4–18.9 — under organic nutrition, 17.1–17.7 — when using complex fertilization, and 19.6% — in the control. Starch content varied within 12.6–13.1% in potatoes. Nitrate content did not exceed the maximum acceptable concentration (250 mg/kg of raw mass). DM concentrations amounted to 19.0–19.8 and 25.0–26.8% in annual and perennial grasses, respectively. Fertilization increased crude protein amount in annual and perennial grasses up to 13.1–15.0% (versus 11.2% in the control) and 8.8–10.6 % (versus 8.1%), respectively.

The utilization of organic fertilizers in farmlands to enhance crop productivity and soil health is increasing globally. Compost and charcoal obtained from the decomposition and slow pyrolysis (respectively) of plants and animals wastes. Here we evaluated the effect of charcoal and compost on the growth and yield of wheat (Triticum aestivum L.) at Agriculture Research Farm Peshawar, Pakistan during 2014-2015. Results showed that the application of compost and charcoal as sole or in combination significantly affected the yield and yield attributes of wheat. Data divulged that the maximum numbers of plant tillers (337 m-2), number of productive tillers per plant (313 m-2), number of grains per spike (56 spike-1) and 1000 seeds weight (50.2 g) were produced by the combined application of compost and charcoal at 5+5 Mg ha-1 while plant height (95.3 cm) was enhanced with the application of charcoal at 10 Mg ha-1. The gain (4106.7 kg ha-1) and biological yield (8473.3 kg ha-1) was significantly increased with the compost application at the rate of 10 Mg ha-1. These results proved that charcoal and compost can be used as organic fertilizers for boosting growth and yield performance of wheat under the agro-climatic conditions of Peshawar, Pakistan.

The overuse of agrochemicals for agricultural productivity to meet the global food demand of the rapidly growing human population is a great environmental threat, particularly for aquatic ecosystems. Being associated intimately with plant health, growth, and productivity, the plant microbiome is emerging as a promising environmentally friendly and sustainable resource for agricultural productivity. For the past decades, our understanding of the interactions between plants and microorganisms and our knowledge of how to improve the plant microbiome by using microbial inoculants has increased significantly. A better understanding of the impact of the plant microbiome on mineral resources will benefit plant and soil health. In this review, we highlight the importance of microbial inoculants and their interactions with mineral fertilizers in enhancing crop productivity, as well as current challenges.

The Impact

An assessment of the impact of long term (>20 years) MSW disposal on soil properties and their suitability for crop productivity was carried out in Anambra and Enugu States of southeast Nigeria. Four dumpsites were selected (two in each state) and, 12 soil auger samples (2 sampling points at 3 depths and 2 repeated measures) each were collected at incremental depth intervals of 0-20, 20-30, and 30-40cm were collected at the dump sites and adjacent non-dumpsites situated 100 meters away from the dumpsites; The auger samples were used for the determination of Fe, B, Pb and Zn content of the soil. Forty Amaranthus spinosus biomass samples were collected from both dump and non-dumpsites in the four locations and also assayed for Fe, B, Pb, and Zn content. Results showed that the mean values of Fe concentration in the dumpsites are between 4.48 – 11.57 mg kg-1 whereas B ranged from 1.19 – 6.73 mg kg-1; Pb ranged from 0.36 – 2.19 mg kg-1 and Zn averaged from 17.2 – 54.0 mg kg-1. The values of these elements were higher than those of the corresponding non-dump sites by between 6-100 %. Pb and Zn with values of 2.0 and 0.06 mg kg-1 respectively in the amaranth plants in the dumpsite soils were higher than the permissive limits for heavy metals in vegetables. Despite the toxicity variance of the elements in the dumpsites and non-dumpsite soils and vegetables, the calculated hazard quotient (ecological risks) values of these elements were less than unity (Q.H.Q < 1), suggesting that harmful effects are not likely to occur in the study areas. Public awareness creation of the dangers of plant cultivation in the unmanaged dumpsite, including health implication of heavy metal pollution and entry into the food chain as well as controlling sources of municipal wastes with appropriate legislations are recommended.

Maize Fertilization

Maize (Zea mays. L) is a source of carbohydrates as food, feed ingredients for livestock and industrial raw materials and bioethanol raw materials. To optimize the productivity of local maize, fertilization can be done. The use of organic fertilizers is very good for maintaining soil health, one of them is vermicompost. The application of vermicompost fertilizer is the right solution in this problem because composting of organic waste with the help of earthworms (Lumbricus sp.) contains high nutrients. The needs of adequate nutrient and growing environment will maximize the genetic potential of a variety. This research was conducted with the aim to determine the effect of vermicompost fertilizer on growth and yield of several maize varieties (Zea mays L). This study used a grooved plot design (Strip Plot) with 3 replications. The vertical path consists of 4 doses of fertilizer, namely P0 = 0 ton /ha, P1 = 4.5 tons/ha, P2 = 9 tons/ha, and P3 = 13.5 ton/ha. Horizontal path consists of 4 varieties, namely V1 = Dampit local variety, V2 = Arjuno superior variety, V3 = Karangploso local variety and V4 = Madura local variety (V4). Results of this study shows that fertilizer dose is 13.5 tons/ha (P3) and themaizeDampit localvariety (V1) showed good results on the growth and yield of maize crops. The results of P3V1 in maize plants were 2.66 kg of maize per bed and 1.15 kg of maize per bed. Keywords: Maize, Varieties, Vermicompost.

The Impact

Agriculture contributes to over 20% of global anthropogenic GHG emissions and irrigated paddy fields account for 5–10% of CH4 emissions. Main organic input providing methanogenesis substrate is straw. We hypothesized that removing rice straw can mitigate CH4 emissions, and that replacing its carbon (C) input with raw or solid digestate can be a valuable alternative both for crop, soil and emission responses. A mesocosm study was setup to follow crop growth, changes in soil pore water chemistry (dissolved Fe(II) and dissolved Organic C), and CH4 emissions over one cropping season on soil treated with the combination of two straw managements (removal or incorporation) and three fertilizations (mineral, raw digestate, solid digestate). Soils not receiving straw on average emitted 38 % less than soils after straw incorporation, while the two organic fertilizers did not increase emissions with respect to mineral N application. Furthermore, straw incorporation induced a yield depression independently from the fertilization strategy, probably as a result of N immobilization, especially in early stages. This was evidenced by early SPAD observations and flag leaf length, and both grain and straw final production. Moreover, the two organic fertilizers were not fully able to sustain crop N requirements with respect to the mineral fertilizer. Straw management was therefore decisive for determining both rice yield and CH4 emissions, while the impact of fertilization treatments was crucial only for crop productivity.

The Impact

Biochar, a carbon-rich material produced by the pyrolysis of organic residues, is frequently used as a soil amendment to enhance soil fertility and improve soil properties in tropical climates. However, in temperate agriculture, the impact of biochar on soil and plant productivity remains uncertain. The objective of this review is to give an overview of the challenges and opportunities of using biochar as an amendment in temperate soils. Among the various challenges, the type of feedstock and the conditions during pyrolysis produces biochars with different chemical and physical properties, resulting in contrasting effects on soils and crops. Furthermore, biochar aging, biochar application rates and its co-application with mineral fertilizer and/or organic amendments add further complexity to our understanding of the soil-amendment-plant continuum. Although its benefits on crop yield are not yet well demonstrated under field studies, other agronomic benefits of biochar in temperate agriculture have been documented. In this review, we proposed a broader view of biochar as a temperate soil amendment, moving beyond our current focus on crop productivity, and instead target its capacity to improve soil properties. We explored biochar’s benefits in remediating low productive agricultural lands, and its environmental benefits through long-term carbon sequestration and reduced nutrient leaching while curtailing our reliance on fertilizer input. We also discussed the persistence of beneficial impacts of biochar in temperate field conditions. We concluded biochar displays great prospective to improve soil health and its productivity, enhance plant stress resilience, mitigate greenhouse gas emissions and restore degraded soils in temperate agriculture.
